Planning for Provisioning


Revised: February 25, 2010, OL-1110-23

This chapter describes how to plan for your system provisioning.

This chapter includes the following sections:

Planning SS7 Signaling Routes

Planning SS7 Signaling Links

Planning Media Gateway Control Links

Route Analysis


Note We recommend that you use two Cisco PGW 2200 Softswitch hosts for maximum availability. The differences in the active and standby hosts are defined in the XECfgParm.dat file, which is configured during software installation. The configuration planned in this chapter applies to both of the Cisco MGCs. You create one configuration for one primary or active node (The standby node cannot be provisioned.) and apply that configuration to both nodes.



Tip This chapter provides worksheets you can use to plan the configuration components. While some tables provide room to define many components, other tables allow you to plan just one component. Before you start your planning, copy the tables and write on the copies. This way, you can make additional copies later if you need them.


Prerequisite Provisioning Information

Before you can complete the provisioning planning tables in this chapter, you must collect the following information:

Device addresses

SS7 point codes

External nodes

Media gateway controller interface card information

Trunk identification data


Note Cisco IP Transfer Point - LinkExtender (ITP-L) is the new name for Cisco Signaling Link Terminal (SLT). Over time, Cisco ITP-L will replace Cisco SLT in publications and the product.


Collecting External Device Addresses

For the control signaling network, list each device attached to the network that has a unique IP address assigned to it. In addition to the device IP address, you should also record a device name, and a description.

Collecting SS7 Point Code Data

The SS7 point codes are SS7 network addresses that uniquely identify every switch, Signal Transfer Point (STP), and Cisco PGW 2200 Softswitch node on the SS7 network. To communicate with the SS7 network, you must get the SS7 point codes for your Cisco PGW 2200 Softswitch and for every SS7 network device with which you are to communicate. At a minimum, you need at least one originating point code (OPC) for the Cisco PGW 2200 Softswitch node and one destination point code (DPC) for the remote switch. If you plan to connect the Cisco Cisco PGW 2200 Softswitch to STPs, you need an adjacent point code (APC) for every STP to which you connect.

Table 2-13 serves as a form you can use to plan point codes for the OPCs, DPCs, and APCs you need to configure. The point code type, network address, and network indicator are required for each SS7 network device. The description column is not required; however, you can use this column to note special information about a point code, such as its geographical location or network administrator.

Collecting External Node Information

An external node is another device, such as a media gateway, with which the Cisco PGW 2200 Softswitch communicates. Within the Cisco PGW 2200 Softswitch software, an external node is a system component that describes another device. The Cisco PGW 2200 Softswitch can connect to a maximum of 1,000 media gateways, and you must configure an external node for each MGW.

External node configuration parameters include:

External node name

Type

Description

ISDN signaling type

M3UA/SUA group number

Table B-16 serves as a form you can use to plan for each external node.

Collecting Media Gateway Controller Interface Card Data

When configuring connections between the Cisco PGW 2200 Softswitch and Cisco IP Transfer Point - LinkExtenders (ITP-Ls), media gateways (MGWs), or SS7 signaling points (SPs), you must be ready to enter information about the name, location, type, and address of the network interface cards. The interface card location and type are determined when the card is installed. The location is identified by the slot where the card is installed, and the type must be the type designation listed in the second column of Table 2-1. Table B-2 serves as a form you can use to record Ethernet interface card information.


Note The CARD component is not supported in software Release 9.4(1).

This MGW signaling service link information can be listed in Table B-21.

Collecting Linkset Data

The linkset must be defined for each link between the Cisco PGW 2200 Softswitch and the adjacent STP. If there are two adjacent STPs, you need to create two linksets (for example, LS01 and LS02). A linkset can contain from 1 to 16 links. You must be ready to enter the following information about each linkset:

Point code

Type of component

Name

Description

Protocol (SS7-ANSI, SS7-China, SS7-ITU, SS7-Japan, or SS7-UK)

IP transport type

This linkset information can be listed in Table B-9.

Collecting Cisco ITP-L Data

A link must be defined for each path from the Cisco ITP-L to the Cisco PGW 2200 Softswitch. There must be one path (two maximum) for each connection between the Cisco ITP-L and Cisco PGW 2200 Softswitch. The link corresponds to the linksets you previously created. You will create a linkset pair for each linkset that exists in your system. For example, if your system has two linksets, you will create two links for each linkset, resulting in your creating a total of four links. You must be ready to enter the following information about each Cisco ITP-L linkset:

Description

Linkset name

Card interface type

Linkset type

Linkset rate

Protocol family variant

Cisco ITP-L IP address

Cisco PGW 2200 Softswitch IP address

This linkset information can be listed in Table B-9.

Collecting Sessionset Data

A sessionset represents a pair of backhaul IP links used on the Cisco PGW 2200 Softswitch. These links are used to communicate with external nodes that support IPFAS, or BSMV0.

Sessionset parameters include:

Peer IP address

Port number

Peer port number

IP route

Type

This sessionset information can be listed in Table B-27.

Collecting C7 IP Link Data

A C7 IP link needs to be defined for each physical SS7 link that is connected to the SS7 network by the Cisco ITP-L. The C7 IP links correspond to linksets you previously created. You must be ready to enter the following information about the C7 IP link:

Description

Linkset

Sessionset

Name

Description

Signal DPC

Linkset

OPC

This SS7 route information can be listed in Table B-12.

Collecting SS7 Subsystem Data

An internal SS7 subsystem must be defined that connects each mated pair of STPs. This allows the Cisco PGW 2200 Softswitch to route traffic over the C-links between the STPs. Thus if one STP fails, the Cisco PGW 2200 Softswitch can route traffic over a C-link to the other STP. The SS7 subsystem component type represents an SS7 subsystem. You must be ready to enter the following data:

MML name of SS7 subsystem

MML name of an SUA key (optional)

Remote subsystem number

The SS7 subsystem component structure is shown in Table B-15.

Collecting Trunk Data (Nailed)

During the provisioning process, you must define all of the nailed bearer trunks that connect remote switches to the media gateway. Each remote switch is identified by its DPC, and each trunk is identified by the trunk ID. Table B-13 provides space for you to provide the following information for the nailed trunks coming from remote switches:

Trunk ID (name)

Source signaling service

Source span

Source time slot/CIC (1)

Destination signaling service

Destination span

Destination time slot/CIC(1)

Span size

To save space, you might want to specify ranges of trunk IDs for each E1 or T1 connection. For large installations, you might want to make copies of this table or create your own worksheet with these columns.

The circuit identification code (CIC) is the SS7 value representing the trunk and must match the CIC value defined at the remote switch.

The destination span ID and destination time slot must match the trunk configuration values defined during Cisco PGW 2200 Softswitch configuration. The destination span ID is defined when configuring T1 and E1 controllers and must match the value of the nfas_int parameter. T1 spans use time slots (channels) 1-24 and E1 spans use time slots 0-31. For more information on gateway configuration, see the Cisco SS7 Interconnect for Access Servers and Voice Gateways Solutions Media Gateway Installation and Configuration Guide.


Note Configure the Cisco PGW 2200 Softswitch first and then configure the MGW. When you configure the Cisco PGW 2200 Softswitch first, enter the Cisco PGW 2200 Softswitch configuration parameters in Table B-13, then use these values when configuring the MGW.


Collecting Trunk Data (Switched)

During the provisioning process, you must define all of the switched bearer trunks that connect remote switches to the media gateway. Each remote switch is identified by its DPC, and each trunk is identified by the trunk ID. Table B-14 provides space for you to provide the following information for the switched trunks coming from remote switches:

Trunk ID (trunk group member number)

Trunk group number

Span

Circuit identifier code

Coding unit

End point

Span size

To save space, you might want to specify ranges of trunk IDs for each E1 or T1 connection. For large installations, you might want to make copies of this table or create your own worksheet with these columns.

The circuit identification code (CIC) is the SS7 value representing the trunk and must match the CIC value defined at the remote switch.


Note Configure the Cisco PGW 2200 Softswitch first and then configure the MGW. When you configure the Cisco PGW 2200 Softswitch first, enter the Cisco PGW 2200 Softswitch configuration parameters in Table B-14, then use these values when configuring the MGW.

Planning SS7 Signaling Routes

To configure routes between the Cisco PGW 2200 Softswitch and a destination device (for example, a switch), you must do the following:

1. Define the point codes (SS7 network addresses) of devices along the signaling route.

2. Define linksets.

3. Override linkset properties (if necessary).

4. Define C link as an SS7 subsystem for each pair of STPs.

5. Define an SS7 signaling service to support the signaling route.

6. Override the SS7 signaling service properties (if necessary).

7. Define the SS7 signaling route.

Figure 2-1 shows the relationship of these components. Figure 2-2 shows the order in which these components are to be configured.

Figure 2-1 SS7 Signaling Route Configuration Components

Figure 2-2 SS7 Signaling Route Component Hierarchy


Note When provisioning, fully define all components (see Figure 2-2) before deploying a configuration.



Note For properties not described in this chapter, refer to "Components and Properties."


Planning Point Codes (SS7 Network Addresses)

The first step in planning signaling routes is to identify the SS7 network devices that link the Cisco PGW 2200 Softswitch to remote switches. To uniquely identify these network devices, you must assign a point code (see Table 2-2 for a list of point code parameter descriptions) to each network device, which serve as SS7 network addresses. The point codes must be unique within the SS7 network. You must get these point codes from your SS7 network administrator.

Point codes are necessary for the following network devices:

Cisco PGW 2200 Softswitch—Within the Cisco MGC software, the Cisco PGW 2200 Softswitch point code is called the OPC. Use Table B-4 to plan the OPC configuration for your Cisco PGW 2200 Softswitch.

STP—Within the Cisco PGW 2200 Softswitch software, the point code for each STP with which the controller communicates is called the APC. Use Table B-7 to plan the APCs for your Cisco PGW 2200 Softswitch.

Destination switch—Within the Cisco PGW 2200 Softswitch, a remote device's point code is called a DPC. You need a point code for each remote switch with which the MGC node will communicate. Use Table B-5 to plan the DPCs for your Cisco PGW 2200 Softswitch.

When configuring a Cisco PGW 2200 Softswitch, you must enter a point code and a point code type for each Cisco PGW 2200 Softswitch, along with the network address and the network indicator. The point code type is OPC and the point code address is a value in the form of x.x.x. For example, 8.232.72. The two periods separating the three numeric labels are required, and the numeric labels must be entered in decimal values. If your service provider issues these numbers using binary or hexadecimal values, you must convert them to decimal.


Note The point code examples used in this document follow the ANSI SS7 (8bits.8bits.8bits) point code format. However, the Cisco PGW 2200 Softswitch can also support ITU point codes.


For configuring point codes for remote switches, the point code type is DPC. Each point code for an STP is an APC, and the STP point code type is APC. The point code values for DPCs and APCs use the same format (x.x.x) as for OPCs.

To define SS7 network addresses, use the following components:

VSPT name: Originating Point Code

MML name: OPC Table B-6

VSPT name: Destination Point Code

MML name: DPC Table B-5

VSPT name: Adjacent Point Code

MML name: APC Table B-7

TRUEOPC

True OPC

MML name of the true OPC with which the capability OPC is associated. The MML name of previously defined true OPC. It only applies to the capability OPC.


Planning Linksets

After you determine the point codes for your network devices, you must define the linksets that connect each MGC node directly to a remote switch or indirectly to the remote switch through an STP. A linkset is the group of all communication links connecting an MGC node to a specific SSP or STP. When two STPs are defined as mates within the Cisco PGW 2200 Softswitch, the Cisco PGW 2200 Softswitch can use either linkset to connect to the SS7 signaling network.

Table 2-3 lists the configuration parameters you define for each linkset during provisioning. Table B-9 serves as a form that you can use to plan the linksets.

To define linksets, use the following component:

VSPT name: LinkSet

MML name: LNKSET


Note When configuring linksets for STP connections, you will usually configure two linksets for each pair of STPs.

Planning SS7 Subsystems

In the Cisco PGW 2200 Softswitch, an SS7 subsystem is used to mate two STPs or to define SS7 systems that access IN services. When two STPs are defined as mates within the Cisco PGW 2200 Softswitch, the software can use either STP for communications with an external switch. Table 2-5 lists the configuration parameters you define for each SS7 subsystem during provisioning. Table B-15 serves as a form that you can use to plan the SS7 subsystems.


Note You must define one SS7 subsystem for each STP to which the Cisco PGW 2200 Softswitch software connects.


To define an SS7 subsystem, use the following component:

VSPT name: SS7SubSys

MML name: SS7SUBSYS

For mated STPs, the subsystem defined for each STP defines the other STP as the mate using the MATEDAPC parameter.

Table 2-5 SS7 Subsystem Configuration Parameter Descriptions 

MML Parameter Name
Voice Services Provisioning Tool Parameter Name
Description

NAME

MML name

Unique name for this subsystem. Enter as many as 20 alphanumeric characters and enclose in straight quotes. Hyphens (-) can be used.

DESC

Description

Text description of this component. Enter as many as 128 characters and enclose in straight quotes.

LOCALSSN

(formerly SSN)

Local SSN

Subsystem number. Enter an integer from 0 to 255. When mating STPs, SSN = 0. When using Intelligent Network (IN) services, SS7-ANSI, SS7-ETSI, or SS7-ITU, Local SSN can be set to a value greater than 0.
Default = 0.

MATEDAPC

Mated adjacent point code

Adjacent point code for an STP mate. Enter the MML name of previously defined APC. Only used when mating STPs, not when creating AIN subsystems.

OPC

Originating PC

MML name of a previously defined originating point code.

SS7-UK - when mating an STP pair.

If the SVC is an APC, SCCP should not be used (SCCP is not used when mating STP pairs. If the SVC is a TCAPoverIP service, then TCPIP should be used

REMOTE SSN

Remote SSN

Integer from 2 through 254;(0). Can be set to non-zero only for SS7-ANSI, SS7-ETSI, or SS7-ITU. If set to 0, the subsystem is used for mating two STPs. Use LOCALSSN if not specified.

TRANSPROTO

Transport protocol

Transport protocol. Enter the transport protocol of this subsystem. When mating STPs = SCCP. Values: SCCP or TCPIP. Not used when mating STPs.


Planning SS7 Routes

The final step in planning SS7 signaling routes is to define the SS7 routes themselves. Routes are defined in terms of the point codes along the path and the linksets that lead from the MGC node through the STPs to each DPC. Table 2-6 describes the configuration parameters you use to define routes during provisioning. Table B-12 serves as a form you can use to plan your routes. It is a good practice to define two routes to each remote switch. Each route should pass through a different STP in a mated pair. The linkset parameter, LNKSET, defines which STP a route will follow.

To define an SS7 route, use the following component:

VSPT name: SS7Route

MML name: SS7ROUTE

Table 2-6 SS7 Route Configuration Parameter Descriptions 

MML Parameter Name
Voice Services Provisioning Tool Parameter Name
Description

NAME

MML name

Unique name for this route. Enter as many as 20 alphanumeric characters and enclose in straight quotes. Hyphens (-) can be used.

Default = 1.

DESC

Description

Text description of this route. Enter as many as 128 characters and enclose in straight quotes.


Planning the SS7 Signaling Service

The SS7 signaling service is the Cisco MGC software service that communicates over the route with a remote switch. You must define a separate service for each remote switch. Table 2-7 describes each of the SS7 signaling service parameters and provides space for you to plan the configuration of one service. Table B-21 serves as a form you can use to plan your signaling services.

To define an SS7 signaling service, use the following component:

VSPT name: SigSS7

MML name: SS7PATH

Table 2-7 SS7 Signaling Service Configuration Parameter Descriptions 

MML Parameter Name
Voice Services Provisioning Tool Parameter Name
Description

OPC

Originating Point Code

Originating Point Code. Enter the MML name of a previously originating point code.


Changing SS7 Signaling Service Properties

SS7 signaling service properties serve as additional configuration parameters that you can use to tune signaling service communications. Table 2-8 lists the default properties assigned to an SS7 signaling service. These properties apply to all SS7 signaling services you create. You do not have to enter these values.

To change SS7 signaling service properties, use the following component:

Planning SS7 Signaling Links

Once you have planned your SS7 routes (as described in the "Planning SS7 Signaling Routes" section), it is time to plan the communication links between the Cisco PGW 2200 Softswitch and the SS7 SPs. SPs are SS7 network nodes, such as STPs and SSPs, with which the Cisco PGW 2200 Softswitch communicates. The Cisco PGW 2200 Softswitch supports two types of SP links: Cisco ITP-L links and direct SP links. Cisco ITP-L links use the Cisco ITP-L to offload MTP 1 and MTP 2 processing to Cisco ITP-Ls. Direct SP links directly link the Cisco PGW 2200 Softswitch to an SP; the Cisco PGW 2200 Softswitch performs all signal processing including MTP 1 and MTP 2 processing.

While linksets define which SP a given route uses, it is the links that carry the communications traffic. Signaling Link Component Hierarchy (without Cisco ITP-Ls)

This section describes how to plan for provisioning the signaling link components:


1. Create point codes (APC or DPC)

2. Create linkset

3. Override linkset properties (if necessary)

4. Create adapter

5. Create interface

6. Create TDM link


It is best to plan SS7 routes before you configure links, because you define APCs and linksets when defining routes, and these components must be planned and configured before you can configure links. Because the planning of these components is described in the "Planning SS7 Signaling Routes" section, these procedures are not repeated here. This section describes how to plan for provisioning the following components:

Cisco PGW 2200 Softswitch cards

Cisco PGW 2200 Softswitch interfaces

Links

The following sections describe how to plan for each of these components.

Planning Network Cards for Cisco ITP-L Communications

Cards are the hardware cards that are installed on the host computer and provide the network interfaces that communicate with other devices. When planning STP links, you define cards that will communicate with the MGC node Cisco ITP-Ls.


Note In the MGC node, the same cards and interfaces can be used for communication with the Cisco ITP-Ls and media gateways. When this type of configuration is used, separate links are assigned for the Cisco ITP-L and media gateway communications.


All Cisco MGCs will have at least one Ethernet interface card installed. When configuring the Cisco PGW 2200 Softswitch you need to enter the card name, type, slot number, and IP address information. The IP address information is entered by entering or selecting a system variable name, which is associated with an IP address in the XECfgParm.dat file. You configure the IP addresses and assign them to variables using the procedures in Cisco Media Gateway Controller Software Release 8 Installation and Configuration Guide.

Table 2-9 lists the Cisco PGW 2200 Softswitch interface card parameter definitions. Table B-1 serves as a form you can use to enter the configuration information for the network interface cards installed in your Cisco PGW 2200 Softswitch. For Ethernet cards, the system variable is required for configuration, but the IP address and card slot are not required. The IP address column is provided for convenience.

To provision network cards, use the following component:

VSPT name: Adapter

MML name: CARD


Note The CARD component is not provisionable in software Release 9.4(1).

Planning TDM Interfaces for Cisco ITP-L Communications

Each SS7 link in the Cisco PGW 2200 Softswitch node must be associated with an interface component, which must be associated with a network card. The interface represents a physical network connection on the network card.


Note In the Cisco PGW 2200 Softswitch node, the same cards and interfaces can be used for communication with the Cisco ITP-Ls and media gateways. When configured this way, separate links are assigned for the Cisco ITP-L and media gateway communications.



Note TDMIF is not supported in software Release 9.4(1).

Note To prevent a single point of failure in a dual-homed Cisco PGW 2200 Softswitch configuration connected to a VISM in a Cisco MGX8850 (with one IP address), establish IP redundancy by:
Configuring NEXTHOP and NETMASK for all signaling links and session sets.
The external node must be the MGX8850
The hosts must be on different subnets.


Planning A-Links Through Cisco ITP-Ls

After you have planned your cards and interfaces, you are ready to plan the SS7 signaling links. When you configure C7 IP links, you can configure a maximum of two of these links for every Cisco ITP-L. Within the MGC node, the ends of each link are identified as follows:

At the Cisco PGW 2200 Softswitch end of each link, the link is associated with an Ethernet interface, an IP address, and a UDP port.

At the Cisco ITP-L end of each link, the Cisco ITP-L is identified with an IP address and a UDP port.


Tip For SS7 provisioning, keep the following points in mind.
A maximum of 6 OPCs that can be supported.
Enter routing information for the OPC before creating the C7 IP link.
For each OPC added, you must specify a different local port for each C7 IP link.
Provision a maximum of 32 links per local port number. Specify another port number for each additional group of 32 links.


The portion of the link between the Cisco ITP-L and the STP is identified by the TIMESLOT configuration parameter. The TIMESLOT configuration parameter identifies the physical port on the Cisco ITP-L.

To provision the Cisco ITP-L links, use the following component:

VSPT name: C7IPLink

MML name: C7IPLNK


Note When provisioning, fully define all components (see Figure 2-2) before deploying a configuration.


Table 2-12 describes the C7 IP link configuration parameters that define each link. Table B-10 serves as a form you can use to plan a single C7 IP link.

Value range: 0 through 3.


Planning F-Links through Cisco ITP-Ls

After you have planned your cards and interfaces, you are ready to plan the SS7 signaling links. When you configure F-links, you must configure one of these links for every Cisco ITP-L. Within the MGC node, the ends of each link are identified from the Cisco ITP-L to the specific DPC.

Planning F-Links to Signaling Points

After you have planned your cards and interfaces, you are ready to plan the SS7 signaling links. When you configure F-links, you must configure one of these links for every PTI card. Within the MGC node, the ends of each link are identified from the Cisco PGW 2200 Softswitch to the specific DPC.

Planning PRI Backhaul Links

After you have planned your cards and interfaces, you are ready to plan the SS7 signaling links. When you configure PRI backhaul links, you must configure one of these links for every Ethernet card to the media gateway (MGW). Within the MGC node, the ends of each link are identified from the Cisco PGW 2200 Softswitch to the MGW.

Planning Media Gateway Control Links

The MGW control links provide the communication path the Cisco PGW 2200 Softswitch uses to control the bearer traffic that passes through each MGW. Planning MGW control links is similar to planning the other components described earlier in this chapter.

The cards and interfaces are configured in the same way as the cards and interfaces used for SS7 signaling links. In fact, you might be able to use the same cards and interfaces previously planned for your MGW control links. You must define IP link components for MGW communications; you cannot use C7 IP links or TDM links.


Tip Links are logical connections between a Cisco PGW 2200 Softswitch physical interface and another device. You can assign multiple links to any interface. When assigning links, be sure to consider fault tolerance. For example, placing all four links between the Cisco PGW 2200 Softswitch and one MGW on the same interface results in a useless MGW if that interface fails.


This section describes how to plan for provisioning the following component types:

External nodes

Cisco PGW 2200 Softswitch cards

Cisco PGW 2200 Softswitch interfaces

Media gateway signaling services

Override properties (if necessary)

IP links

The following sections describe how to plan for each of these components.

Planning Media Gateway External Nodes

An external node is another device, such as a media gateway, with which the Cisco PGW 2200 Softswitch communicates. Within the Cisco MGC software, an external node is a system component that describes another device. The Cisco PGW 2200 Softswitch can connect to a maximum of 1,000 media gateways, and you must configure an external node for each MGW.

To provision media gateway external nodes, use the following component:

VSPT name: ExtNode

MML name: EXTNODE


Note If you are configuring a redundant system, you must define two redundant link manager links between each Cisco PGW 2200 Softswitch and MGW. Each redundant link manager group must be associated with a different port number and a different NASPATH, but the same EXTNODE.


Table 2-13 describes the external node configuration parameters. Table B-16 serves as a form you can use to plan for each media gateway.

To provision a media gateway signaling service, use the following component:

VSPT name: Multiple IPFAS

MML name: MLTIPFAS

VSPT name: SigNAS

MML name: NASPATH

VSPT name: SigEISUP

MML name: EISUPPATH

VSPT name: SigIPFAS

Even though the name parameter is limited, use a description that will allow someone else to understand the network well enough to scale or troubleshoot it.


Planning Network Cards for Media Gateway Communications

Network cards are the hardware cards installed on the host computer providing the network interfaces that communicate with other devices. When planning media gateway control links, you define the cards that will communicate with the media gateways.


Note In the MGC node system, the same cards and interfaces can be used for communication with Cisco ITP-Ls and media gateways. When configured this way, separate links are assigned for Cisco ITP-L and media gateway communications.



Note CARD is not supported in software Release 9.4(1).


To provision cards, use the following component:

VSPT name: Adapter

MML name: CARD

Table 2-16 describes configuration parameters you can use to configure network cards. Table B-1 serves as a form you can use to plan network card configurations.

Planning Ethernet Interfaces for Media Gateway Communications

Each SS7 link in the MGC node must be associated with an Ethernet interface component, which must be associated with a network card. The Ethernet interface represents a physical network connection on the network card.


Note In the MGC node, the same cards and interfaces can be used for communication with Cisco ITP-Ls and media gateways. When configured this way, separate links are assigned for Cisco ITP-L and media gateway communications.


To provision an Ethernet interface, use the following component:

VSPT name: EnetIF

MML name: ENETIF


Note ENETIF is not supported in software Release 9.4(1).


Table 2-17 describes the configuration parameters that define an Ethernet interface. Table B-2 serves as a form you can use to plan the Ethernet interfaces on your Cisco PGW 2200 Softswitch.

Text description of this interface. Enter as many as 128 characters and enclose in straight quotes.


Planning IP Links

The last step in planning media gateway control links is the planning of the links themselves. You must identify each end of each link as follows:

At the Cisco PGW 2200 Softswitch end of each link, the link is associated with an Ethernet interface, an IP address, and an IP port.

At the media gateway end of each link, the Cisco ITP-L is identified with an IP address and port.

To provision a media gateway IP link, use the following component:

VSPT name: IPLink

MML name: IPLNK

Table 2-18 lists and describes the configuration parameters that define each link. Table B-23 serves as a form you can use to plan a single IP link.

Table 2-18 IP-Link Configuration Parameter Descriptions

Signaling service this IP link supports. Enter the MML name of a previously defined signal service.

NEXTHOP

Next hop

0.0.0.0

Router IP address where packets are to be sent for delivery to the PEERADDR that is not a subnet directly connected to the Cisco PGW 2200 Softswitch. Typically the PEERADDR is on a subnet directly connected to the Cisco PGW 2200 Softswitch. NEXTHOP can be specified in dot notation or using the DNS name. Optional parameter. Value range: 0.0.0.0 (default, disables the IP routing feature) through 223.255.255.255.

NETMASK

Note NEXTHOP and NETMASK are used only if the Cisco PGW 2200 Softswitch is on a different subnet than the Cisco PGW 2200 Softswitch and ITP-L are located. However, if the local IP address and peer IP address are on the same subnet, set NEXTHOP to 0.0.0.0.



Note For proper operation of redundant IP links (using MGCP signaling) connected to an IP media gateway, configure the IP gateway with the IP address of the VISM card on the IP media gateway. Both of these IP addresses are typically the default network gateway for each VLAN. Ensure the IP netmask matches the VISM card netmask of the IP links connecting to the IP media gateway and is not the netmask of the default gateway.


Planning Backhaul TCP Link

The Backhaul TCP link component represents a static IP route. Its MML name is as follows:

MML Name—TCPLINK

The Backhaul TCP link component structure is shown in Table 2-19.

The following attributes cannot be modified:

NAME

EXTNODE

The following rules apply when you are creating or editing QSIG/Q.931 Over BRI Backhaul signaling services:

You must define the TYPE parameter as PRI. If the TYPE parameter is not defined as PRI when the TCPLINK is added/edited, a warning is issued. If the TYPE parameter is not defined as PRI when the provisioning session is copied or deployed, an error message is generated and the copy or deployment is stopped.

You must define the TCPLINK parameter with the same EXTNODE attribute that its associated BRIPATH has. If the TCPLNK is not defined when the BRIPATH is added/edited, a warning is issued. If the TCPLINK is not defined when the provisioning session is copied or deployed, an error message is generated and the copy or deployment is stopped.

If the TCPLINK with the same EXTNODE value as the BRIPATH is deleted, a warning message is issued to inform you that the BRIPATH must also be deleted. If the BRIPATH is not deleted when the provisioning session is copied or deployed, an error message is generated and the copy or deployment is stopped.

Only two combinations of local IP address and port number can be used per Cisco PGW 2200 Softswitch. Once you have identified two unique local IP address and port number combinations, all subsequent Backhaul TCP links must use one of those combinations.

Planning QSIG/Q.931 Over BRI Backhaul Signaling Service

Note If you are using the ETS_300_102 or Q931 protocol files, this should be set to 1. If you are using the ETS_300_172 protocol file, this should be set to 2.



The following attributes cannot be modified:

NAME

EXTNODE

The following rules apply when you are creating or editing QSIG/Q.931 Over BRI Backhaul signaling services:

You must define the TCPLINK parameter with the same EXTNODE attribute that its associated BRIPATH has. If the TCPLNK is not defined when the BRIPATH is added/edited, a warning is issued. If the TCPLINK is not defined when the provisioning session is copied or deployed, an error message is generated and the copy or deployment is stopped.

If the TCPLINK with the same EXTNODE value as the BRIPATH is deleted, a warning message is issued to inform you that the BRIPATH must also be deleted. If the BRIPATH is not deleted when the provisioning session is copied or deployed, an error message is generated and the copy or deployment is stopped.

A maximum of 2000 BRIPATHs can be provisioned on your Cisco PGW 2200 Softswitch.

Planning Session Sets

The session set component is used for ISDN and SS7 backhaul over RUDP links. A session set represents a pair of backhaul IP links used on the Cisco PGW 2200 Softswitch. These links are used to communicate with external nodes that support IPFAS. You must identify each link in the session set as follows:

At the Cisco PGW 2200 Softswitch end of each link, the link is associated with a port, an IP address, and a peer address.

To provision a session set, use the following component:

VSPT name: Session Set

MML name: SESSIONSET

Keep the following points in mind when provisioning session sets.

The PEERPORT and PEERADDRESS must be unique for each backhaul IP link created.

IPADDR1 and IPADDR2 must be different.

Once a session set is created, it cannot be separated.

A maximum of 50 IPFAS session sets are supported per port.

The following attributes cannot be modified:

NAME

EXTNODE

TYPE

This command will generate a session set, which is one or two (if IPADDR2 and PEERADDR2 are specified) backhaul IP links. The names are "NAME-1" and "NAME-2". The DESCRIPTIONs are "Session Set `NAME' Backhaul Link 1" and "Session Set `NAME' Backhaul Link 2".

All commands (add, edit, delete, and retrieve) are performed against the pair by only specifying the "NAME". Retrieving a session set displays the backhaul IP links (there may only be one) for the session set. Retrieving all session sets displays all backhaul IP links.

The ISDNSIGTYPE of the EXTNODE must be N/A.

The session set TYPE must be BSMV0 for C7 session sets.

The session set TYPE must be IPFAS for IPFAS session sets.

IP Addresses cannot be split across session sets. For example if SET 1 has IP_Addr1 and IP_Addr2, then SET 2 cannot have IP_Addr1 and IP_Addr3.

If IPADDR2 or PEERADDR2 is specified, then they must both be specified. You cannot have one local address and two remote addresses or two local addresses and one remote address.

IPADDR1 and IPADDR2 must be different.

PEERADDR1 and PEERADDR2 must be different, except when the EXTNODE is a VISM (MGX8850).

The PORT attribute cannot be set to the same value as the PORT attribute of any ASSOCIATION, IPLNK, or SIPLNK.

The PORT attribute cannot be set to the same value as the PORT attribute of another SESSIONSET with a different TYPE value. That is, the PORT value of a BSMV0 SESSIONSET cannot be the same as the PORT value of an IPFAS SESSIONSET.

When IPROUTE1 or IPROUTE2 is specified, the IP address value from the PEERADDR1 or PEERADDR2 attribute must be the same as the DESTINATION and NETMASK attributes to ensure the IPROUTE is valid.

When IPROUTE1 is specified, the IPADDR must match the IPADDR1 of the session set.

Similarly, when IPROUTE2 is specified, the IPADDR must match the IPADDR2 of the session set.

When IPROUTE1 or IPROUTE2 is not specified, the IP address value for the PEERADDR1 or PEERADDR2 attribute must match the defined IPROUTES to ensure it should not be assigned to one of the IPROUTEs. If the PEERADDR is on the same subnet as an IPROUTE, then the link should use that IPROUTE.

Another IPLNK, SESSIONSET, or ASSOCIATION with a different EXTNODE cannot use the same PEERADDR value.

Table 2-21 lists and describes the configuration parameters that define each session set. Table B-27 serves as a form you can use to plan a single session set.

Planning for D-Channels

A D-channel is the signaling channel between the Cisco PGW 2200 Softswitch and an external node. One D-channel is created for a FAS interface and up to two D-channels for an NFAS interface. The second D-channel is a backup D-channel to prevent a single point of failure for NFAS. There can be a maximum of two D-channels per IPFAS. Table 2-15 lists and describes the configuration parameters that define each D-channel. Table B-31 provides space to plan a D-channel between the Cisco PGW 2200 Softswitch and a gateway.

To provision a D-channel, use the following component:

MML name: DCHAN

VSPT name: D Channel

This parameter identifies the subunit value on the external node when you create a trunk with a VISM or IOS gateway endpoint. When you create a BRI trunk, this parameter identifies the subunit of the slot.

Values are: 0, 1, 2, 3, 99.

Note Required for QSIG/Q.931 Over BRI Backhaul D-channels.

Note Use 99 only for onboard 2-tuple T1/E1 controller on NM-HDV2-1T1/E1 and NM-HDV2-2T1/E1 and so forth.


The following rules apply when you are creating or editing D-channels:

Backup D-channels for QSIG/Q.931 Over BRI Backhaul signaling services are not supported.

The priority for QSIG/Q.931 Over BRI Backhaul D-channels should be set to 1.

Session sets are used only in support of IPFAS D-channels.

TCP links are used only in support of QSIG/Q.931 Over BRI Backhaul D-channels.

Up to 1000 D-channels can be provisioned against a single IP address and port combination used by your Backhaul TCP links. Since the Cisco PGW 2200 Softswitch supports a maximum of two IP address and port combinations, you can provision a maximum of 1000 D-channels for a QSIG/Q.931 Over BRI Backhaul signaling service.

Planning for NOA Line Translation

Configurable NOA mapping is supported in Cisco PGW 2200 Softswitch software Release 9.4(1) and allows you to translate an external NOA value to any internal NOA value for inbound or outbound calls.

Provisioning Trunk Groups and Trunks

There are two different methods that can be used to provision trunk groups and trunks. Provisioning can be performed individually creating each trunk group and trunk by using MML commands. Or provisioning can be performed by importing a customer-created file.

Provisioning Trunk Groups and Trunks Using MML Commands

Provisioning trunk groups and trunks can be performed using MML commands. Examples of the provisioning MML commands are contained in this chapter. More extensive MML command examples are listed in Chapter 5 "Adding Components with MML."

When provisioning using MML commands, it is important to realize that the MML commands are used to add to existing components. Therefore, MML commands are very useful when modifying existing trunk groups and trunks. However, if you have to create large trunk group or trunk files, importing a file can greatly speed the provisioning effort.

Provisioning Trunk Groups and Trunks Using an Imported File

Importing a customer-created file is another way to provision trunk groups and trunks. The customer file can be created using Voice Services Provisioning Tool or a text editor. MML commands cannot be used to create the customer file. After the file is created, you must import it into the Cisco PGW 2200 Softswitch. When importing this file, you can use either MML commands or the Voice Services Provisioning Tool.

When provisioning using an imported customer-created file, it is important to realize that the imported file overwrites the existing file. For example, if a customer-created trunk group file is imported, the existing trunk group file is overwritten.

Provisioning a Nailed Configuration

Adding Nailed Trunks

You need to add trunks for each connection between the MGW and a destination switch. These trunks can be either nailed or switched. For nailed trunks, the Cisco PGW 2200 Softswitch does not perform switching of trunks. To create a nailed trunk, you can use an MML command to create a single trunk, use the Voice Services Provisioning Tool to create a trunk, or use the MML command to import a trunk file created using a text editor. To add multiple nailed trunks, refer to the "Adding Multiple Nailed Trunks" section.

The MML command format used to create one nailed trunk is:

prov-add:nailedtrnk:name="1910",srcsvc="ss7svc1",srctimeslot=101,dstsvc="nassrv1", 
dstspan=3,dsttimeslot=1,spansize=1
 
   

Table 2-25 lists the nailed trunk MML command parameter definitions and their associated values.

Table 2-25 Nailed Trunk Parameter Descriptions

Used to look up the destination service component ID. The MML name of a previously defined signaling service.

DSTSPAN

Destination span ID

Corresponds to the destination span ID. Value range: an integer from 1 through 65535 or ffff (default). This value is converted from decimal to hexadecimal, except when the value is ffff.

DSTTIMESLOT

Destination time slot

Corresponds to the destination time slot. Value range: an integer from 0 through 16384. This value is converted from decimal to hexadecimal, except when the value is ffff.

SPANSIZE

Span size

Span size. Indicates the number of trunks per span. Value: 1 (default) through 24 for T1, or 1 through 31 for E1.


The MML command format used to import a customer-created nailed trunk file is:

prov-add:files:name="BCFile",file="trunkCust.dat",action="import"
 
   

This imports the customer-created file that uses #format2. The imported file format would appear as:

Trunk	Src	Src	Src	Dest	Dest	Dest     
ID	cmp-id	Span	Time slot	cmp-id	Span	Time slot
 
   
101	00130002	ffff	65	00140001   3      1
102	00130002	ffff	66   	00140001   3      2
 
   

The #format2 fields are Trunk ID, Source Service CompId, Source Span, Source Time slot, Destination Service CompId, Destination Span, and Destination Time slot.

Configuring Profiles

Profiles allow one or more property values to be overridden and then applied as a customized group called a profile. Two profile types exist:

GRPROFILE — a profile of GR properties for trunk groups

ISUPTMRPROFILE — a profile of ISUP timers for signaling service

For example, a property that belongs to a profile can be added to a single trunk group or repeatedly to many trunk groups without having to provision all the parameters for each trunk group.

Table 2-26 lists the profile MML command parameter definitions and their associated values.

Table 2-26 Profile Parameter Descriptions

Configuring Signaling Service Profiles

ISDN User Part (ISUP) timer profile properties allow property values, listed in "Components and Properties," to be overridden for the specified protocol.

When configuring an ISUP timer profile, you can attach a profile to a signaling service, but both the profile and the signaling service must belong to the same variant (refer to "Components and Properties" for a list of variant names). However, you can create a profile even though the signaling service does not exist.

The following is an MML command format used to create an ISUP timer profile and attach it to a signaling service:

prov-add:profile:name="mtp3profile1",type="isuptmrprofile",variant="ISUPV2_FRENCH",T1="140

Note A profile must be created before a signaling service can be associated with the profile.


Configuring ATM Profiles

When the Cisco PGW 2200 Softswitch is acting as a Call Agent making ATM Voice Connections between two Gateways, the Cisco PGW 2200 Softswitch must provide the capability to influence the profile negotiation between the sides. To facilitate ATM profile negotiation, the AtmConnectionType and GWDefaultATMProfile trunk group property settings are used. These two trunk group properties are described in the following sections.

AtmConnectionType

The trunk group property AtmConnectionType populates the connection type parameter (ct:) in local connection option parameters. This property is read for both originating and terminating legs of all ATM-switched calls.

Applying Cisco PGW 2200 Softswitch influence, that is, bias, in the profile negotiation process is hierarchical and is applied through using the GWDefaultATMProfile property at the trunk group level, and then by analysis results in A-number or B-number analysis.


Note ATM profile negotiation can work over Extended ISUP (EISUP) too.


Valid values: 1 (AAL1), 2 (AAL1_SDT), 3 (AAL1_UDT), 4 (AAL2), 5 (AAL 3/4), 6 (AAL5)

Default value: 4 (AAL2)

Profile Negotiation Levels

This implementation provides the following structure with regard to ATM profile negotiation when the Cisco PGW 2200 Softswitch is involved.

Level 0

At level 0, nothing is defined on the Cisco PGW 2200 Softswitch. That is, no trunk group properties and no analysis results are defined. This means that the decision for the profile used for the call is made at the gateway level. However, the Cisco PGW 2200 Softswitch, using MGCP messages, negotiates between ingress and egress gateway. This is the only role of the Cisco PGW 2200 Softswitch at this level.

Level 1

At level 1, the Cisco PGW 2200 Softswitch can influence the profile negotiation by the trunk group property GWDefaultATMProfile configuration on the originating side and even on the terminating side.

With GWDefaultATMProfile configured on the originating side, the Cisco PGW 2200 Softswitch offers to the originating gateway the profile list extracted from this property within the CreateConnection (CRCX) request. The originating gateway then matches this received list with its own ActiveProfileList to produce a new list composed of the matched profiles. This list is returned by the gateway to the Cisco PGW 2200 Softswitch in the SDP information returned in the CRCX Acknowledgement.

If the terminating side trunk group has this property configured, the retrieved profile list is sent along with the SDP profile list (received previously from the originating side) to the terminating-side gateway.

If no terminating trunk group property is configured, then only the originating-side SDP information is sent.


Note With regard to the terminating side, the trunk group property profile list is read only in the absence of any level 2 results from A-number or B-number analysis.


The Cisco PGW 2200 Softswitch passes the originating SDP and any retrieved terminating profile list to the terminating-side gateway in another CRCX message. The egress gateway then matches the received list with its own ActiveProfileList to develop a final list. The egress gateway then chooses from this resultant final profile list, which is transported back to the Cisco PGW 2200 Softswitch in the CRCX Acknowledgement message.

Finally, the Cisco PGW 2200 Softswitch passes this profile choice to the originating gateway in an MDCX message. Once this exchange has been carried out, only one profile exists for both the ingress and egress gateways, which is the result of profile negotiation (influenced by the Cisco PGW 2200 Softswitch applying a bias for the SLA between those gateways).

Level 2

At level 2, the Cisco PGW 2200 Softswitch can apply another layer of SLA bias to profile negotiation. This additional layer provides the capability of provisioning ATM_ORIG_PROFILE and ATM_TERM_PROFILE results within the Cisco PGW 2200 Softswitch A-number and B-number analysis functions. These results contain the same data words and both results deliver a profile list to bias negotiation on either the ingress or egress gateway.

Dataword2 in the result type provides a mandatory or preferred indication for the profile list, which determines the actions that must take place. If dataword2 is set to mandatory, then the profile list from the previous stages is ignored and the egress gateway supports a profile from the list identified by dataword1. If dataword2 is set to preferred, then the profile list identified by dataword1 is retrieved and the existing list (from previous stages, if collected) is appended to the profile list, thus forming a new list to forward to the gateway.


Note If results are collected from A-number analysis and then from B-number analysis, B-number analysis can further adjust or overwrite the existing profile list created by the A-number analysis. This provides the possibility for there being two sublevels within the level 2 capability.


GWDefaultATMProfile

When the Cisco PGW 2200 Softswitch is acting as a Call Agent making ATM voice connections between two gateways, it must provide the capability to influence the profile negotiation between the two sides to the gateway.

To accomplish this profile negotiation, a list of profiles supported by the code image on the gateway, but is refined by configuration according to the prevailing network Service Level Agreement (SLA). The Cisco PGW 2200 Softswitch applies the SLA changes or refinements to the profile list rather than apply them as configuration changes on the gateways. Thus, the gateways contain a list of profiles that their respective code images can support. The Cisco PGW 2200 Softswitch retrieves a provisioned profile list from the GWDefaultATMProfile trunk group property or as the ATM_ORIG_PROFILE or ATM_TERM_PROFILE result delivered from A-number (Calling number) or B-number (Called number) analysis. This list is then passed over MGCP to the gateway to bias profile negotiation.

While establishing the connection between two gateways, the originating gateway profile list is refined by ANDing with a new profile sent from the Cisco PGW 2200 Softswitch in the originating side CRCX message. The resultant profile list is passed in the Session Description Protocol (SDP) to the terminating gateway. Also, the Cisco PGW 2200 Softswitch can optionally produce another profile choice to bias the profile on the terminating gateway according to the SLA. This profile accompanies other data sent in the CRCX message to the terminating gateway. Upon receiving this profile, the terminating gateway ANDs the SDP profile with any existing received profiles and then ANDs the profile list with the existing gateway ActiveProfileList to produce a resultant profile list. From the resultant profile list, the gateway chooses a profile entry and passes back the profile list to the originating side.

The Cisco PGW 2200 Softswitch produces a profile choice list (ProfileList1) that is sent to the originating gateway in the first CRCX command. The originating gateway forms a new list by ANDing the received profile with its own ActiveProfileList and generates ProfileList2, which consists only of the profile choices that were present in both lists. This profile information is embedded in the SDP that is sent back to the Cisco PGW 2200 Softswitch in the CRCX Acknowledgement.

If the Cisco PGW 2200 Softswitch also has an SLA profile for the terminating gateway (ProfileList3), it is added to the profile list in the SDP and both profiles are sent to the terminating gateway in another CRCX message. Upon receiving this profile, the terminating gateway ANDs all three lists to produce a single profile list that is refined by the SLA conditions from both sides. The terminating gateway makes a choice from the final profile list that is then sent to the Cisco PGW 2200 Softswitch in the CRCX Acknowledgement message and the profile is then sent to the originating gateway in an MDCX message.

Once this process has been carried out, a single profile exists for both the originating and terminating gateway, which is the result of profile negotiation between the two gateways by the Cisco PGW 2200 Softswitch and application of the prevailing SLAs.

The trunk group property GWDefaultATMProfile provides, on a per trunk group basis, an initial list of profiles for use in ATM gateway profile negotiation. This property contains a list of profile choices separated by semi-colons, that influences ATM gateway profile negotiation. If GWDefaultATMProfile is set to NULL (default), then there is no profile list negotiation bias applied from the trunk group level.

Valid values: NULL, <Profile1>;<Profile2>;<ProfileN>

Default value: NULL


Note This property is added in propSet.xml.dat for provisioning, added in properties.mod for migration, and added in tpTrunkgroup for importing and exporting.


Creating the Trunk Group

Before switched trunk groups and trunks can be created, the following two files need to be created:

Trunk group file—Used to define the trunk group and the signal path controlling the trunk group

Trunk file—Used to define the trunks (also called bearer channels) associated with a trunk group. The trunk file is a switched trunk.

You can either use MML commands to import a trunk group file or you can use the following MML command to populate a trunk group one line at a time.

Populating a Trunk Group File

After you create a trunk group file, you need to populate that file. Trunk group information is used to populate the trunkGroup file and spawns information for the Properties file and the SigPath file.

Table 2-29 lists the MML trunk group parameters, the corresponding VSPT names, the parameter definitions and the associated values.

Table 2-29 Trunk Group Parameter Descriptions

10 = SS7 Japan 29 = QSIG MASTER
17 = 5ESS 30 = QSIG SLAVE
20 = SS7 Clear 40 = SS7 ITU
22 = NI2

SELSEQ

Selection sequence

Specifies the trunk selection sequence. The Cisco PGW 2200 Softswitch uses the CICs within a trunk group according to the sequence specified by the SELSEQ value. You can provision this value to reduce the chance of glare when the system selects a trunk.

ASC = Ascending. The system selects the available CICs in ascending order starting from the lowest CIC number (for example, 1, 2, 3 ...).

CASC = Cyclic ascending. The system selects the next available CIC in ascending order based on the most recently selected CIC. For example, if the most recently selected CIC is CIC 5, the system selects CIC 6, even if CIC 1 is available.

CDESC = Cyclic descending. Similar to CASC, but in descending order based on the most recently selected CIC. For example, if the last selected CIC is number 18, the system selects CIC 17, even if CIC 31 is available.

DESC = Descending. Similar to ASC, but in descending order starting from the highest CIC number (for example, 31, 30, 29 ...).

EASC = Even ascending, then odd ascending. The system selects the first available even CIC in ascending order (for example, 2, 4, 6 ...). If no even CIC is available in the trunk group, the system selects the first available odd CIC in ascending order (for example, 1, 3, 5 ...).

EDECS = Even descending, then odd descending. Similar to EASC, but in descending order. The system selects the first available even CIC in descending order (for example, 30, 28, 26 ...). If no even CIC is available in the trunk group, the system selects the first available odd CIC in descending order (for example, 31, 29, 27 ...).

ITU2 = ITU method 2. The system selects the trunk according to the procedure in ITU-T Recommendation Q.764, paragraph 2.9.1.3 Method 2.

LIDL = Least idle (default). The system selects the least idle (most recently used) CIC.

MIDL = Most idle. The system selects the most idle (least recently used) CIC.

OASC = Odd ascending, then even ascending. The system selects the first available odd CIC in ascending order (for example, 1, 3, 5 ...). If no odd CIC is available in the trunk group, the system selects the first available even CIC in ascending order (for example, 2, 4, 6...).

ODESC = Odd descending, then even descending. Similar to OASC, but in descending order. The system selects the first available odd CIC in descending order (for example, 31, 29, 27 ...). If no odd CIC is available in the trunk group, the system selects the first available even CIC in descending order (for example, 30, 28, 26 ...).

RDM = Random. The system selects a CIC at random.


Caution When the trunk selection sequence (SELSEQ) is set to its default value, LIDL (least idle), there is a risk that the Cisco PGW 2200 Softswitch will select a significant number of temporarily unavailable trunks, which causes calls to fail. This kind of call failure can happen when an overloaded media gateway responds to the Cisco PGW 2200 Softswitch with a temporary MGCP error (400 to 499), or the Cisco PGW 2200 Softswitch does not receive a response from the media gateway in time. We recommend that you set SELSEQ to a value other than LIDL.

QABLE

Queuable

Determines if queuing is used on the trunk during call processing. Value range: Y for yes or N for no (default).


In addition to the trunk group parameters listed in Table 2-29, additional properties can be set or changed in the text file. To add multiple trunk groups, refer to the "Adding Multiple Trunk Groups and Bearer Channels" section. Table 2-30 lists the trunk group property MML parameter definitions and their associated values. For a description and provisioning order in which they appear in the VSPT Configuration Editor, see Table 3-18 in Chapter 3 "Provisioning with the Cisco Voice Services Provisioning Tool."

Route Analysis

Routing analysis is necessary to identify the path for bearer traffic from the Cisco PGW 2200 Softswitch to the adjacent switch.

Creating a Routing Trunk Group

You need to create a routing trunk group. You can use either the MML command to create a routing trunk group or use the Voice Services Provisioning Tool to import a routing file.

Provisioning a Routing Trunk Group Using MML Commands

Provisioning routing trunk groups can be performed using MML commands. Examples of the provisioning MML commands are contained in this chapter. More extensive MML command examples are listed in Chapter 5 "Adding Components with MML."

The MML command format used to create a row in the routing trunk group file is:

prov-add:rttrnkgrp:name="1910",type=7,reattempts=1,queuing=0,cutthrough=2
 
   

Table 2-32 lists the routing trunk group MML command parameter definitions and their associated values.

Table 2-32 Routing Trunk Group Parameter Descriptions

MML Parameter Name
Voice Services Provisioning Tool Parameter Name
Description

NAME

Name

Unique name for this routing trunk group number. Enter as many as 20 alphanumeric characters and enclose in straight quotes. Hyphens (-) can be used.

TYPE

Type

Identifies the trunk group type. Value range: 0 through 11.

0 = TDM_GEN (default)—Used with SS7 signaling services with switch types not equal to 0, 5, 20, 23, or 40.
1 = TDM_ISUP—Used with SS7 signaling services with switch types of 0, 5, 20, 23, or 40.
2 = TDM_CAS—Currently not supported.
3 = TDM_TUP—Used with SS7 signaling services with switch type of 5.
4 = IP—Used with EISUP signaling service.
5 = ATM—Used with VSI path signaling service.
6 = TDM_DPNSS—Used with DPNSS protocol family signaling services.
7 =TDM_ PRI—Used with ISDN PRI protocol family signaling services.
8 = TDM_BTNUP—Used with SS7 signaling services with switch type of 5.
9 = IP_SIP—Used for SIP signaling services at the terminating side.
10 = SIP_IN—Used for SIP signaling services at the originating side
11 = CTI—Used for CTI signaling.

Switch type values are:

0 = No switch-specific logic 23 = SS7 ANSI
for the signaling path. 26 = DPNSS
5 = BTNUP 27 = NET5
10 = SS7 Japan 29 = QSIG MASTER
17 = 5ESS 30 = QSIG SLAVE
20 = SS7 Clear 40 = SS7 ITU
22 = NI2

REATTEMPTS

Reattempts

Identifies the number of times the system reattempts to select the same trunk group due to congestion. If, after the specified number of reattempts, a trunk group is not selected, the call is released.
Value range: 0 (default) through 5.

QUEUING

Queuing

Identifies the duration (in seconds) the call will be queued when circuit selection on a trunk group has failed. The value specified is the time (in seconds) the call is queued and waits for a circuit to become free. If a circuit becomes free before the time interval expires, the call is completed. If no circuit becomes available before the elapsed time, the call is released.
Value range: 0 (default) through 120.

CUTTHROUGH

Cutthrough

Identifies the point in the call process where the trunk is seized from end point to end point. Value range: 0 (default) through 3.

0 = Undefined
2 = ACM
3 = Answer

RESINCPERC

Reserve Incoming Percentage

Identifies the percentage of bandwidth for incoming calls. It defaults to 0 if ResIncomingPerc is not defined. Value range 0 (default) through 100.

BEARERCAPNAME

Bearer Capability Name

Unique name for this bearer capability (NULL). Enter as many as 20 alphanumeric characters and enclose in straight quotes. Hyphens (-) can be used.


Associating a Route with a Trunk Group

You need to create a route to connect to a trunk group. You can use either the MML commands to associate a route with a trunk group or use the Voice Services Provisioning Tool to import a routing file.

The MML command format used to create a row in the route trunk file is:

prov-add:rttrnk:name="rt1910",trnkgrpnum=501910
 
   

Table 2-33 lists the route trunk MML command parameter definitions.

Table 2-33 Route Trunk Parameter Descriptions

MML Parameter Name
Voice Services Provisioning Tool Parameter Name
Description

NAME

Name

Unique name for this routing trunk group. Enter as many as 20 alphanumeric characters and enclose in straight quotes. Hyphens (-) can be used.

TRNKGRPNUM

Trunk group number

Identifies the trunk group number.

NEXTTRKGRP

Next trunk group

Identifies the next trunk group number.


Each line entry in the route trunk file is one entry in the route list file.

Weighted Trunk Group

Weighted trunk group based routing allows the same trunk group to be used multiple times in the same route when the random distribution algorithm is enabled. The user has the option of setting the distribution indicator on the route entry to determine how the trunk groups are selected in each route. If the distrib parameter is OFF then sequential selection is used to choose the trunk groups in that route. If the distrib parameter is ON then random selection is used, this is useful if there is a need to balance the choice of trunk groups across the connected equipment. This required an extra parameter to be added at the rttrnk level to specify if weighted trunk group base routing is enabled. If weighted trunk group based routing is enabled or disabled at the route trunk level, then the following rules must be observed:

If weighted trunk group based routing is enabled at the route trunk level, any route list that it is connected to must have distribution enabled to ensure that the random algorithm is used.

If weighted trunk group based routing is enabled at the route trunk level, then the same route trunk group can be added to the route trunk multiple times.

If weighted trunk group based routing is disabled at the route trunk, then the same route trunk group cannot be added to the rttrnk multiple times.

If the route trunk has the same route trunk group connected to it more than once, the weighted trunk group based routing cannot be changed to disabled.

If the route list is connected to an route trunk that has weighted trunk group based routing enabled, the distribution parameter for the route list cannot be changed from on to off.

If the route trunk has weighted trunk group based routing as enabled, then the nexttrkgrp parameter is not supported.

When the user deletes the route trunk group from an route trunk that has multiple route trunk group of the same value, it only deletes the first route trunk group in the list.

Limit the number of route trunk group in an route trunk to 100.

For weighted trunk group based routing, you add the same route trunk group to the route trunk multiple times for it to be weighted trunk group based routing.

There following MML example creates the routing data with 25% of the calls on trunk group 1111 and 75% of the data on trunk group 2222 for the route trunk called route1.

prov-sta::srcver="new",dstver="test",confirm
prov-add:rttrnkgrp:name="1111",type=0
prov-add:rttrnkgrp:name="2222",type=0,reattempts=5,queuing=2,cutthrough=3
prov-add:rttrnkgrp:name="3333",type=0,reattempts=1,queuing=1,cutthrough=1
prov-add:rttrnk:name="route1",trnkgrpnum=1111,weightedtg="ON"
prov-ed:rttrnk:name="route1",trnkgrpnum=2222,weightedtg="ON"
prov-ed:rttrnk:name="route1",trnkgrpnum=2222
prov-ed:rttrnk:name="route1",trnkgrpnum=2222
prov-add:rttrnk:name="route2",trnkgrpnum=3333,weightedtg="OFF"
prov-add:rttrnk:name="route3",trnkgrpnum=2222,weightedtg="OFF"
prov-add:rtlist:name="one",rtname="route2",distrib="OFF"
prov-add:rtlist:name="two",rtname="route1",distrib="ON"
prov-add:rtlist:name="three",rtname="route3",distrib="OFF"
prov-stp

Note Additional trnkgrpnums can be added to the rttrnk with or without enabling the weightedtg parameter. If the second weightedtg had been set to OFF, then the whole rttrnk would not allow weighted trunk group based routing. Route1 must be connected to an rtlist with distrib ON since the weighted trunk group was set to ON.


Creating a Route List

After you have finished creating a route trunk, you need to create a route list. You can use either the MML command to create a route list, use the Voice Services Provisioning Tool, or import a routing file.

The MML command format used to create the route list is:

prov-add:rtlist:name="rtlist1910",rtname="rt1910",carrierid=333
 
   

Table 2-34 lists the route list MML command parameter definitions and their associated values.

Table 2-34 Route List Parameter Descriptions 

MML Parameter Name
Voice Services Provisioning Tool Parameter Name
Description

NAME

Name

Unique name for this route trunk. Enter as many as 20 alphanumeric characters and enclose in straight quotes. Hyphens (-) can be used.

RTNAME

Route name

Used to look up the source service component ID.

NEXTRTNAME

 

Next route name.

DISTRIB

 

Sequential distribution. Values are: Off (default) to use sequential selection to choose the trunk group in the route; or On to use random selection.



Note What is called route list in MML is called a route group in Voice Services Provisioning Tool.


An MML Example for Creating a Routing File

The following MML commands provide a sample routing file.

prov-add:rttrnkgrp:name="1910",type=7,reattempts=1,queuing=0,cutthrough=2
prov-add:rttrnkgrp:name="2744",type=1,reattempts=1,queuing=0,cutthrough=2
prov-add:rttrnkgrp:name="3913",type=7,reattempts=1,queuing=0,cutthrough=2
prov-add:rttrnkgrp:name="3914",type=1,reattempts=1,queuing=0,cutthrough=2
prov-add:rttrnk:name="rt1910",trnkgrpnum=1910
prov-add:rttrnk:name="rt2744",trnkgrpnum=2744
prov-add:rttrnk:name="rt3913",trnkgrpnum=3913
prov-add:rttrnk:name="rt3914",trnkgrpnum=3914
prov-add:rtlist:name="rtlist1910",rtname="rt1910"
prov-add:rtlist:name="rtlist2744",rtname="rt2744"
prov-add:rtlist:name="rtlist3913",rtname="rt3913"
prov-add:rtlist:name="rtlist3914",rtname="rt3914"

Planning for Session Initiation Protocol Provisioning

To pass calls between the Cisco PGW 2200 Softswitch and a Session Initiation Protocol (SIP) domain, configure the following SIP parameters using MML commands:

SIP signal path

SIP link

SIP trunk group

Domain Name System

You must create a SIP routing trunk group. You can use either the MML command to create a SIP routing trunk group or use the Voice Services Provisioning Tool to import a routing file.

Table 2-35 SIP Routing Trunk Group Parameters
