Backhaul Set

The Backhaul Set (backhaul-set) table defines an entity for IP communication between a Call Agent and a media gateway for ISDN signaling. It is used to group entries in the Reliable User Datagram Protocol Backhaul Session table.

Table Name: BACKHAUL-SET

Table Containment Area: Call Agent

Command Types

Show, add, change, and delete

Examples

show backhaul-set set-id=backset1;

add backhaul-set set-id=isdn1; mgw-id=mgw_isdn; set-name=set1;

change backhaul-set set-id=isdn1; set-name=set3;

delete backhaul-set set-id=isdn1;

Usage Guidelines

Primary Key Token(s): set-id

Foreign Key Token(s): mgw-id

Add Rules: None.

Change: Control trunk groups using this set to admin-oos.

Delete Rules: Foreign key constraints.

---

Note If using these commands after a system upgrade, use the mgw-id as the set-id. There is one entry for each ISDN media gateway. The hard code set-name = ISDN1.

ISDN Interface

The ISDN Interface (isdn-intf) table defines the number of T1s per primary rate interface (PRI). This table is provisioned before the Trunk table. The number of entries for a trunk group is dependent on whether it is nonfacility associated signaling (NFAS) and facility associated signaling (FAS). FAS trunk groups have only one entry in this table, and with an INTF value of zero (0). NFAS trunk groups have multiple entries in this table; one for each T1.

ISDN Trunk Group Profile

The ISDN Trunk Group Profile (isdn-tg-profile) table holds common information regarding an ISDN trunk group. This table is used to configure the Cisco BTS 10200 Softswitch to interact with various types of private branch exchanges (PBXs) having different configurations (such as NFAS, FAS, and so forth), initialization procedures (service or restart), or supporting different call control or maintenance timer values. The isdn-tg-profile record can be shared by multiple ISDN trunk groups. The table tokens configure the Call Agent to communicate with a particular PBX.

Reliable User Datagram Protocol Backhaul Session

The Reliable User Datagram Protocol (RUDP) Backhaul Session (rudp-backhaul-session) table specifies the IP connections between a media gateway and the Call Agent for ISDN call processing.

Table Name: RUDP-BACKHAUL-SESSION

Table Containment Area: Call Agent

Command Types

Show, add, change, and delete

Examples

show rudp-backhaul-session set-id=isdn1;

add rudp-backhaul-session set-id=backset1; group-name=group1; session-name=session1; 
mgw-tsap-addr=10.89.227.200; mgw-backhaul-port=9000; call-agent-tsap-addr=10.89.225.223; 
call-agent-backhaul-port=9000;

change rudp-backhaul-session set-id=backset1; group-name=group1; session-name=session1; 
call-agent-backhaul-port=17777;

delete rudp-backhaul-session set-id=isdn1;

Usage Guidelines

Primary Key Token(s): set-id, group-name, session-name

Foreign Key Token(s): set-id

Add Rules: None.

Change: Control trunk groups using this set to admin-oos.

Delete Rules:

•Foreign key: constraints

•Allowed only if the media gateway supports ISDN.

(Release 4.5.1) For medium configurations, if configuring 2000 D-channels, changes to the RUDP retransmission timeout value configured in the gateway can adversely affect link recovery times. Lost calls can occur on switchover. The retransmit timer value must be above 1000 in order to maintain all active calls during switchover. For example:

group group1 timer retransmit 2000

group group2 timer retransmit 2000

Syntax Description

* SET-ID	Primary key. Foreign key: Backhaul Set table. Specifies which backhaul set to gateway to use for communication. Must match a set-id in the Backhaul Set table. VARCHAR(16): 1-16 ASCII characters.
* CALL-AGENT- BACKHAUL-PORT	Specifies the Call Agent port connected to the MGW backhaul port. Only applicable if the MGW supports ISDN. SMALLINT: 1-65536.
* CALL-AGENT- TSAP-ADDR	DNS or IP address of the Call Agent. Domain names cannot begin with a number. VARCHAR(64): 1-64 ASCII characters.
* GROUP-NAME	Primary key. Name for a collection of sessions. VARCHAR(16): 1-16 ASCII characters.
* MGW-BACKHAUL- PORT	Media gateway port number is used to backhaul ISDN signaling. Used only if the MGW supports ISDN. SMALLINT: 1-65535.
* MGW-TSAP-ADDR	DNS or IP address of the media gateway. Domain names cannot begin with a number. VARCHAR(64): 1-64 ASCII characters.
* SESSION-NAME	Primary key. Name of the connection between a media gateway and the Call Agent. Usually specified as Session1, Session2, Session3, and Session4. VARCHAR(16): 1-16 ASCII characters.
AUTO-REFRESH	Specifies whether to display cached data on the screen. Valid only for the show command. CHAR(1): Y/N (Default = Y). Y—Queries the database for the most current data. N—Queries the database for the most current data only if the cached data is unavailable.
DISPLAY	Specifies what token information to display on the screen. Valid only for the show command. VARCHAR(1024): 1-1024 (Default = all tokens are displayed). Permitted values are any valid token that can be shown for this command. Multiple tokens can be entered by separating with a comma.
LIMIT	Specifies the number of rows to display on the screen. Valid only for the show command. INTEGER: 1-100000000 (Default = 100000000). Note The actual maximum number of rows displayed is currently lower than 100000000 due to software limitations.
ORDER	Specifies whether to display data on the screen in a sorted order. Valid only for the show command. VARCHAR(1024): 1-1024 (Default = all rows are displayed). Permitted values are any valid token that can be shown for this command. Multiple tokens can be entered by separating with a comma.
