This chapter describes how to provision BTS Call Agents (CAs) and Feature Servers (FSs).
Call Agents
The CA provides signaling and call processing (call setup and teardown) for the BTS. This section describes adding the CA and associated office tables to the BTS. The following table provides example steps to provision the CA and lists examples of CLI commands with mandatory tokens. For all available tokens, see the Cisco BTS 10200 Softswitch CLI Database.
Step
Task
Description and CLI Command
Step 1
Adding CAs.
The Call Agent (call-agent) table has the domain name and tsap addresses of the CA as well as the primary and secondary IP addresses of the EMS.
add call-agent id=CA101;
Step 2
Adding CA profiles.
The Call Agent Profile (ca-agent-profile) table defines the properties (functionality) of the CA. The CA reads this table once every 20 calls. This means that when the CA processes 20 calls per second, changes to this table take effect in one second.
The Call Agent Configuration (ca-config) table defines the defaults for each CA. The defaults are prepopulated at installation. Only change and show commands are valid.
Note The add command is used during installation but additional parameters cannot be added.
The Call Agent Configuration Base (ca-config-base) table is a static table in the EMS to perform constraint checks. This table is not provisionable. Only the show command is allowed. Information in the Call Agent Configuration Base table must match the information in the Call Agent Configuration table.
Step 4
Adding home area codes.
The National Destination Code (ndc-code) table defines the home area codes supported by the CA.
add ndc digit-string=469;
Step 5
Adding exchange codes.
The Exchange Code (exchange-code) table specifies the exchange codes assigned to a particular CA.
add exchange-code ndc=469; ec=255;
Step 6
Adding office codes.
The Office Code (office-code) table specifies the office codes assigned to a particular CA. The office codes defined in this table normally terminate to a subscriber. This table defines the office-code-index (normalized office code) that is used as an index in the DN2Subscriber table.
The Digit Map (digit-map) table tells a media gateway (MGW) how to collect and report dialed digits. The CA uses a default digit map ID for normal digit collection unless a specific digit map ID is assigned to the subscriber. POTS subscribers use a public dialing plan. Centrex subscribers use a customized dialing plan.
Note This digit pattern permits the creation of both 2- and 3-digit VSCs. If the first digit is 2 or 3, the length is 3 digits. If first digit is 4-9, the length is 2 digits. For example: *2-3xxx *4-9xx
Step 8
Adding points of presence.
The CA can serve several geographical regions or Metropolitan Statistical Areas (MSAs) simultaneously. Each geographical region is referred to as a point of presence (POP). Each POP has its own unique dialing and routing characteristics. The Point of Presence (pop) table contains a default dialing and routing characteristics. Each originating entity (subscriber or trunk group) is assigned to a POP. The POP also performs policy routing, for example, it routes the call to the nearest announcement server in the POP or to the nearest interLATA carrier location within a POP.
add pop id=1; state=tx; country=usa; timezone=CST;
Feature Servers
The FS provides access to features through a well-defined interface, Feature Control Protocol (FCP). BTS FS architecture separates feature control from call control with a clear interface defined between them. The CA uses FCP to provide an effective environment for interfacing with multiple FSs. This provides AIN, POTS, Centrex, and 800 services as required during call processing.
A FS is invoked from a detection point (DP). At the DP, the CA checks if any triggers are armed. If they are, the CA checks if the trigger applies to a subscriber, group, or office, in the order specified. If the trigger is applicable, the CA invokes the feature associated with that trigger.
The following table lists the steps for provisioning a BTS FS and provides commands with mandatory tokens.
For all available tokens, see the Cisco BTS 10200 Softswitch CLI Database.
Note When adding an FS, add the entries to the CA as well as the FS tables in the respective FSs. The POTS FS has the Feature Server table, but the AIN FS does not.
Description
Description and CLI Command
Step 1
Adding FSs.
The Feature Server (feature-server) table identifies the location and type of FS (POTS or AIN). It also identifies the IP address of the primary and secondary EMS and MGWs used by the FS. It is updated at both the CA and the applicable FS. The FS can be prepopulated during installation using a script, and it is used to automatically provision the Service Trigger table.
The Feature (feature) table defines characteristics for the features supported by the BTS. Repeat this step for each feature you want to add to the system.
The Vertical Service Code (vsc) table translates a vertical service code, also known as a star code (*XX), to a feature name. This table is preprovisioned, based on the Feature table customer records, during installation.
add vsc digit-string=*72; fname=CFUA;
Step 4
Adding services.
A service is a collection of one or more features that are invoked when a trigger is reached. Each feature within a service can have one or more triggers. Services can be dynamically created within the BTS 10200. The service provider defines a service and the features associated with it. Up to 10 commonly used features can be grouped into a service, and up to 50 services can be provisioned per subscriber. The subscriber is then provisioned with a service-id instead of individual features.
add service id=1; fname1=CFU; fname2=CFB; fname3=CFNA;
fname4=CW;

TOS, DSCP, and PHB
This section describes how BTS supports Type of Service (TOS), Differentiated Services Codepoint (DSCP), and Per-Hop Behavior (PHB). For more information, see the following IETF documents:
•TOS—RFC 791, Internet Protocol
•DSCP—RFC 2474, Definition of the Differentiated Services Field (DS Field) in the IPv4 and IPv6 Headers
•PHB—RFC 2597, Assured Forwarding PHB Group, and RFC 3246, An Expedited Forwarding PHB (Per-Hop Behavior)
Figure 2-1 shows how the TOS, DSCP, and PHB standards are related.
Figure 2-1 Relationship of TOS, DSCP, and PHB Standards
On the BTS, the parameters for TOS, DSCP, and PHB are provisioned differently depending on the token.
Caution Restart or swtichover the CA to effect changes you make in the ca-config table.
TOS
If the BTS requires TOS parameters as precedence strings, provision tokens as follows:
If the BTS requires Diffserv parameters as bytes, provision a single token as an integer, 0 - 255. The Diffserv byte is based on 8 bits, 2 more bits than the DSCP value. For example, if you want a DSCP value of 24, provision it with 96.
DSCP
If the system requires parameters to be provisioned in the DSCP value format, provision a single token as an integer between 0 and 63. The DSCP value is the decimal equivalent of the first 6 bits of the Diffserv byte.
PHB
If the system requires parameters to be provisioned in the PHB format, provision a single token as one of the following values: CS0, CS1, CS2, CS3, CS4, CS5, CS6, CS7, AF11, AF12, AF13, AF21, AF22, AF23, AF31, AF32, AF33, AF41, AF42, AF43, EF, DEFAULT.
Note Entering the value "DEFAULT" has the same effect as entering "CS0." These values are included in Table 2-5.
Combined PHB/DSCP Format
Some tokens can be provisioned in either the alphanumeric PHB format or the numeric DSCP value format. In this case provision the token as one of the following values: an integer between 0 and 63, CS0, CS1, CS2, CS3, CS4, CS5, CS6, CS7, AF11, AF12, AF13, AF21, AF22, AF23, AF31, AF32, AF33, AF41, AF42, AF43, EF, DEFAULT.
Refer to RFC 791 for additional information on the PRECEDENCE values. The relationship between PRECEDENCE and CSx values is as follows: NETCONTROL=CS7, INTERNETCONTROL=CS6, CRITICAL=CS5, FLASHOVERRIDE=CS4, FLASH=CS3, IMMEDIATE=CS2, PRIORITY=CS1, ROUTINE=CS0/DEFAULT.
Allowed and Default Values
This section lists the provisionable TOS, DSCP, and PHB tokens applicable to each protocol.
Caution Cisco recommends against using any value other than the default. Changing these values from their defaults can significantly impact network performance. Contact Cisco TAC for further information.
Caution If you change any parameters in the ca-config table, these changes do not take effect until the CA platform switches over or restarts.
MGCP Signaling
The MGCP-SIG-DSCP parameter from the CA_CONFIG table is used for signaling between the BTS 10200 and MGWs.
SIP Signaling
The SIA-TRUNK-GRP-LEVEL-SIG-TOS parameter from the CA_CONFIG table applies to SIP signaling. For its changes to take effect, you must performa switchover.
•Y: Use the value provisioned for SIP-SIG-DSCP in the SIP-ELEMENT table for the applicable SIP trunk group.
•N: Use the value provisioned for the system-wide parameter SIA-SIG-DSCP in the CA-CONFIG table.
The SIA-SIG-DSCP parameter from the CA_CONFIG table defines system-level DSCP for SIP calls.
TheSIP-SIG-DSCP parameter in the SIP_ELEMENTtable applies to trunk-level SIP signaling.
CA to FS Signaling
TheSIM-SIG-DSCP parameter from the CA_CONFIG table applies.
FS to CA Signaling
The following values from the CA_CONFIG table apply:
•The FSAIN-SIG-DSCP value is used for internal AIN Feature Server (FSAIN) to CA signaling.
•The FSPTC-SIG-DSCP value is used for internal POTS/Tandem/Centrex Feature Server (FSPTC) to CA signaling.
DQoS Signaling
DQoS signaling uses the Common Open Policy Service (COPS) protocol. The RTP-DSCP from the QOS table applies.
H.323 Signaling
The SIG-DSCP parameter from the H323_GATEWAYtable applies.
COPS and RADIUS Signaling
This section lists the tokens used in provisioning COPS and RADIUS signaling from the QOS and CA_CONFIG tables.
Tip The tokens in this section are provisioned using values between 0 and 255. For an explanation of how to calculate these values, see the "Diffserv" section.
TheQOStable contains the following token (applicable to voice traffic):
•DQOS-CMTS-DSCP-TOS—This value is used for the packets about to enter a provider backbone from the CMTS.
•DQOS-DSCP-TOS-BITMASK—This token specifies particular bits within the IPv4 DSCP/TOS byte.
•DOCSIS-DSCP-TOS—Identifies the DSCP/TOS value that must be matched for packets to be classified onto the IP flow.
•DOCSIS-DSCP-TOS-BITMASK—This token determines what bits in the DSCP/TOS byte are to be used as filters in classifying packets.
Table 2-4 lists the allowed values and default value for each of these tokens.
Mapping of Provisionable TOS, DSCP, and PHB Values
Table 2-8 shows how the provisionable values in the PHB format are mapped to the values in TOS and DSCP formats.
Caution Cisco recommends using the combinations of values in the table. BTS accepts other combinations, depending on format; however, the combinations shown have been tested by Cisco.
Note Binary and Hex values are informational and not used for provisioning.
Table 2-8 Mapping of Provisionable Values in PHB Format to TOS and DSCP Formats1
1Cisco recommends that you use the combinations of values shown in the table. The system will accept certain other combinations of values, depending on the format; however, the combinations shown in the table have been tested by Cisco for proper behavior.
2Hexadecimal equivalent. This value is listed for convenience. It is not used in provisioning the BTS.
3Binary equivalent. This value is listed for convenience. It is not used in provisioning the BTS.
4D = Delay, T = Throughput, R = Reliability. To provision these tokens, enter N for 0 or Y for 1.
When adding an FS, add the entries to the CA as well as the FS tables in the respective FSs. The POTS FS has the Feature Server table, but the AIN FS does not.
