Adding System Components with MML
This chapter describes how to add system components, describes how to verify the addition of the components, and gives tips that can help you solve problems. It provides information about:
•
Adding SS7 Signaling Route Components
•Adding Signaling Link Components
•Adding MGW Control Links
•Adding Trunks, Trunk Groups, and Routing
Before starting an actual configuration, refer to "Planning for Provisioning" for instructions and worksheets for configuring your system. That chapter describes the system components that need to be configured on the MGC. Each component has a specified type, name, and description, and may have additional configuration parameters.
When adding components, add the components in the following order.
•External nodes
•Point codes (OPC, APC, and DPC)
•Adapter cards
•Adapter interfaces
•Signaling services
•Linksets
•Links
•SS7 routes
•SS7 subsystems
•Trunk groups
•Trunks
•Route groups
Adding SS7 Signaling Route Components
Your first task is to configure SS7 signaling routes that link the MGC to the SS7 network nodes (signaling points). You typically do this by:
•Adding a Point Code
•Adding an Adjacent Point Code
•Adding a Linkset
•Adding an SS7 Subsystem
•Adding an SS7 Route
•Adding an SS7 Signaling Service
•Adding a TCAP over IP Signaling Service
•Adding a FAS Signaling Service
Note When provisioning, fully define all components (see Figure 2-2) before deploying a configuration.
To add a system component, do the following:
Step 1 Start MML as described in the "Working with MML" section.
Step 2 Start a provisioning session as described in the "Starting a Provisioning Session" section. The source configuration that you chose during startup determines the configuration to which you can add components.
Step 3 Enter the following command:
prov-add:componentType:name="name", desc="description", paramName=value
Replace the componentType parameter with the type of component you want to create. To define more than one parameter, enter the additional paramName=value descriptions on the command line.
Provide a description. The description can be as many as 128 alphanumeric characters in length.
Replace the name parameter with the name you want to give to the component. The name can be as many as 20 characters in length and can only be number and letter symbols, and the dash (-) symbol.
SS7 System Component Hierarchy
When you are adding SS7 system components, create them in proper order. For example, before you add a point code, you must define the external nodes.
Adding a Point Code
A point code is an SS7 network address that identifies an SS7 network node, such as a switch, SCP, STP, or SSP. Its MML name is PTCODE. This can be the MGC's originating point code (OPC) or the destination point code (DPC) of a remote node with which the MGC communicates.
Note For information on point code parameters, refer to Table 2-1.
Procedure
To add a point code to the MGC configuration, use the PROV-ADD command.

|
Verify
Use the PROV-RTRV command to verify.
Tip Point codes provide the addressing scheme for the SS7 network. ITU point codes are 14 bits long, and ANSI point codes are 24 bits long.
Adding Multiple OPCs
Depending on your system configuration, you may have to assign more than one OPC to a single MGC. When adding multiple OPCs, keep the following information in mind.
•ITU point codes contain 14 bits and ANSI point codes contain 24 bits.
Note Use care when supplying ITU point codes since they are not checked in the provisioning session.
•A maximum of 6 true OPCs can be supported per MGC.
•For each OPC added, you must specify a different local port number for each C7 IP link on the same interface.
•For each OPC added, you must create a duplicate DPC with a different name but with the same
IP address.
•Each OPC must have a unique network address.
•Enter the OPC before creating the C7 IP link.
•When specifying a local port number, it must be greater than 1024 (for example, 7000).
•Each OPC requires its own linkset (a linkset cannot be shared by 2 OPCs).
•A maximum of 2 Session Manager sessions (1 active and 1 standby) can be supported per SLT (1 session per link).
•A maximum of 32 links can be supported per Control Channel.
•A maximum of 16 linksets can be included per Control Channel.
•A maximum of 4,096 DS0s (CICs) can be supported per OPC-DPC pair for ITU or a maximum of 16,384 DS0s (CICs) for ANSI.
Procedure
To add another point code to the MGC configuration, use the PROV-ADD command.

Scaling System Components
After you have configured your system components, you can begins scaling your system. Keep the following in mind when scaling.
Tip A maximum of 6 OPCs can be supported per MGC.
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. As many as 192 links can be supported per MGC.
Planning for future network expansion by spreading the linksets evenly across the Control Channels is suggested. Failure to do so will require the linksets to be removed from service to add more links.
As many as 256 NASs can be supported. When creating IP links to the NASs, increment the MGC port number after 32 links have been added. Be sure to set the NAS RLM to match the MGC RLM port value.
Dynamically Configuring the Input/Output Channel Controller
When dynamically configuring the IOCC, evenly distribute number of channels associated with one channel controller. For different signaling service, there are different rules when associating channels with channel controllers. The number of links associated with a channel controller is configurable on a protocol family basis through parameters contained in XECfgParm.dat. If the number of links exceeds the limit defined in XECfgParm.dat, a new instance of channel controller is created.
The naming convention for creating a new channel controller is the first five characters of the protocol family, plus a dash (-), and <num>, where num is number of channel controllers per protocol family created so far.

Port number.
Number of links.
When a channel controller is created, the RLM port number is created as the property port for this channel with the value of the actual port number (minus 1) in properties.dat. The format is:
<IOCC MML Name>.port = <port number> - 1
|
Local port and peer port must be the same.
The port number must always be an odd number.
The number of links on the same port cannot exceed the maximum number of links specified in XECfgParm.dat.
Links associated with the same signaling service must use the same port number. (that is, redundant links).
Redundant links do not count when validating the maximum number of links per IOCC.
