Reference Information
46
Cisco MGC Software Release 9.5(2)
The following rules apply when you are creating or editing D-channels:
• Backup D-channels for QSIG/Q.931 Over BRI Backhaul signaling services are not supported.
• The priority for QSIG/Q.931 Over BRI Backhaul D-channels should be set to 1.
• Session sets are used only in support of IPFAS D-channels.
• TCP links are used only in support of QSIG/Q.931 Over BRI Backhaul D-channels.
• Up to 1000 D-channels can be provisioned against a single IP address and port combination used by
your Backhaul TCP links. Since the Cisco MGC supports a maximum of two IP address and port
combinations, you can provision a maximum of 1000 D-channels for a QSIG/Q.931 Over BRI
Backhaul signaling service.
The commands to retrieve and set the service state of a D-channel can be found in the “Retrieving the
Service State of D-Channels” section on page 36 and the “Setting the Service State of a D-Channel”
section on page 33.
