Support for QSIG Over BRI and Q.931 Over BRI Backhaul
Reference Information
45
Cisco MGC Software Release 9.5(2)
• NAME
• EXTNODE
The following rules apply when you are creating or editing QSIG/Q.931 Over BRI Backhaul signaling
services:
• You must define the TCPLINK parameter with the same EXTNODE attribute that its associated
BRIPATH has. If the TCPLNK is not defined when the BRIPATH is added/edited, a warning is
issued. If the TCPLINK is not defined when the provisioning session is copied or deployed, an error
message is generated and the copy or deployment is stopped.
• If the TCPLINK with the same EXTNODE value as the BRIPATH is deleted, a warning message is
issued to inform you that the BRIPATH must also be deleted. If the BRIPATH is not deleted when
the provisioning session is copied or deployed, an error message is generated and the copy or
deployment is stopped.
• A maximum of 2000 BRIPATHs can be provisioned on your Cisco MGC.
The commands to retrieve and set the service state of an QSIG/Q.931 Over BRI Backhaul signaling
service can be found in the “Retrieving Signaling Service States” section on page 35 and the “Setting
the Service State of a Signaling Service” section on page 32.
