To enable BSR polling over IP without the B-channel, you must:
● Set up the signalling group for H.323, QSIG, and NCA-TSCs
● Set up the designated trunk group for ISDN and IP, with at least one trunk assigned.
! Important:
Important: If an IP Media Processor circuit pack is not installed, the Trunk Group Status
form indicates the trunk as out-of-service. However, status poll signaling over D-channel is not affected.
The forms that you must administer to enable BSR polling over IP without the B-channel are described in the following sections:
● Pattern formon page 109
● Signaling Group formon page 110
● Trunk Group formon page 110
● Feature-Related System Parameters form (ISDN)on page 113

Pattern form
Use the display route-pattern xx command (where xx is the route pattern used by the trunk group that supports the TSCs) to display the Pattern form. Verify that your administration settings comply with the following requirement:
● In the TSC column, set the value to y.
An example route-pattern form that is configured for BSR polling over IP without the B-channel is shown below.
Best Service Routing form
Use the display best-service-routing xx command (where xx is a BSR application plan number) to display the Best Service Routing form. Verify that your administration settings comply with the following requirement:
● The Status Poll VDN field must specify an AAR or AAS pattern that routes over an IP trunk.
! Important:
Important: Do not specify a TAC in the Status Poll VDN field. If you do so, the poll will
route through a B-channel, if one is available.

Signaling Group form
Use the display signaling-group xx command (where xx is the signaling group number) to display the Signaling Group form. Verify that your administration settings comply with the following requirements:
● You must specify the TSC-related fields in the upper-right corner of the field. The relevant fields include:
- Max number of NCA TSC:
- Trunk group for NCA TSC:
● The Supplementary Services Protocol: field must be set to b.
An example signaling-group form configured for BSR polling over IP without the B-channel is shown as follows.
Trunk Group form
Use the display trunk-group xx command (where xx is the signaling group number) to display the Trunk Group form. Verify that your administration settings comply with the
requirements listed below each of the following example form pages.
Examples for the key pages in the Pattern form that must be configured for BSR polling over IP without the B-channel are shown as follows.
