Multiple Trunk Groups on a Single ISDN

D-Channel

Revised: January 31, 2008, OL-12436-02

The Cisco BTS 10200 Softswitch supports ISDN 23B+D on a single T1 port with the ability to define

explicit routing from a DN to a group of CICs or DS0s. To support using a different DN to route to an

ISDN 23B+D, multiple trunk groups must be provisioned on a single D-channel. The trunk group is a

logical entity used to group a range of B-channels or a single B-channel in a D-channel (ISDN T1).

Specific DNs can be associated to the trunk groups for explicit routing of a DN to a specific range of

B-channels in the ISDN D-channel (23B+D).

This section describes provisioning multiple trunk groups on a single ISDN D-Channel.

Step 1

Add one ISDN D-channel id.

add isdn-dchan id=40089; dchan-type=primary; dchan-format=slot-port;

dchan-slot=2;dchan-port=21;sctp_assoc_id=c5400_102;

backhaul-type=IUA;isdn_dchan-profile-id=NI2; dchan-intf=0;

Provision multiple trunk groups to the same ISDN D-channel id (40089). In this example, 6 trunk

Step 2

groups: 9950, 9951, 9952, 9953, 9954, 9955 are provisioned.

add trunk-grp id=9950;call-agent-id=CA146;tg-type=ISDN;tg-profile-id=tb78-isdn-dchan1;
