Integrating Data, Voice, and Video Services for ISDN Interfaces
Bandwidth for H.320 Calls
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.

Enabling Integrated Services on the Interface
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.

are voice calls, is not available.

By default, the integrated service option is disabled from the supported interfaces. Use the following
