T-CCS Bandwidth Usage

I'm considering T-CCS to connect a couple PBX's over a T1 Serial link. I'm also going to be running regular data traffic over the link and am concerned about the amount of bandwidth a T-CCS connection uses. Does anyone have any numbers on this? Can I use LLC with the T-CCS?

Re: T-CCS Bandwidth Usage

This depends mostly on the codec you decide to use and also if you keep VAD disable or enable.

For bandwidth calc you can follow the attached link..

Hope that helps..

Re: T-CCS Bandwidth Usage

The bandwidth calculation is also seen here:

The clear channel would take 80k, and if you used 23 channels at g729, cRTP, and FRF12 fragmentation, each channel would take 11.6k, so that is 346.8k.
