Cisco Cisco IOS Software Release 12.4(11)T

Each c5510 digital signal processor (DSP) channel supports 64 kilobits of bandwidth. Each c5510 DSP 
has 16 channels available. One of those channels can support a bandwidth of 1024 kbps, allowing the 
DSP to support one H.320 call with a maximum of 16 B-channels. For each dial peer configured for 
information-type video, an optional bandwidth command can be added that specifies the minimum 
acceptable and maximum allowed bandwidth for the H.320 call, in 64-kbit increments. If the number of 
call legs connected falls between the minimum and maximum configured, then video is allowed. If the 
minimum bandwidth cannot be met for the call, the call drops back to an audio-only H.320 call.

This section describes how to configure integrated data, voice, and video services for ISDN BRI or PRI 
interfaces, and includes the following tasks:

Enabling integrated services allows video and voice call traffic to occur from ISDN BRI or PRI 
interfaces simultaneously. 

When an interface is in integrated service mode:

ISDN performs call type checking for the incoming call. The call is rejected by ISDN if no voice or 
data dial peer is matched for an incoming call.

The voice option for the isdn incoming-voice command, which handles all incoming calls as if they 
are voice calls, is not available.

By default, the integrated service option is disabled from the supported interfaces. Use the following 
procedure to enable integrated mode on a serial interface.
