This section describes the supported ISDN profiles.
Maintenance Message Support
This section describes the ISDN D-channel profile parameters, which hold information about the ISDN
D-channels. These parameters are used to configure the Call Agent to interact with various types of
PBXs having different configurations (for example, FAS), initialization procedures (Service or Restart),
supporting different call-control or maintenance timer values, and so forth.
The following definitions and meanings apply:
•
The Call Agent can send restart messages to a PBX during trunk group initialization (restoral). The
restart message can be any of the following:
–
One for all interfaces (all B channels on all T1 interfaces)
–
One for each interface (all B channels on a specified T1 interface)
–
A separate restart message for individual (indicated) B channels
•
The PBX can support sending service messages to the Call Agent.
–
Support by the PBX means the PBX takes action on service messages from the Call Agent and
sends an acknowledgment message back to the Call Agent.
–
Nonsupport by the PBX means the PBX does not send an acknowledgment message back to the
Call Agent.
•
Maintenance message support using service and restart messages handles the protocol discriminator
for national coding (0x43). Unsolicited service acknowledgment messages are also handled,
including proper update of the trunk or channel states.
The ISDN D-channel profile is provisioned using the CLI. See the
Cisco BTS 10200 Command Line
Interface Reference Guide
for additional information. The following tokens configure the Call Agent to
communicate properly with the PBX:
•
ISDN-RESTART-PRI-SUPP
–
SIf YES—The CA sends a restart message for all interfaces (Restart Class 7).
–
If NO—The PBX does not support a restart message for all interfaces (Restart Class 7). The CA
will not send a “Restart All Interfaces” message.
•
ISDN-RESTART-INTERFACE-SUPP
–
If YES—The PBX supports a restart message for single interface (Restart Class 6). The CA
sends a single restart message for an individual interface.
–
If NO—The PBX does not support a restart message for a single interface (Restart Class 6).
•
ISDN-SERVICE-SUPP
–
If NO—The PBX does not support service messages (B-channel availability). The CA sends a
single service message for an individual channel.
–
If YES—The PBX supports service messages (B-channel availability).
•
ISDN-RESTART-CHAN-SUPP
–
If YES—The CA sends single restart messages for individual channels (Restart Class 0).
