asterisk users - Dec 2003 - Where is D channel in a PRI link?

We have contracted with Eschelon to provide voice and data over a T1 
link.  The plan is to terminate this link at a T100P card in the * system.

The vendor has said that they will provide the D channel "contiguous to 
the voice channels" (voice on channels 1-8 and D channel on 9).  The 
data channels would be 20-24.

Will the T100P be able to accept this configuration?  Does the PRI 
specification mandate where the D-channel should be?

Thanks for your help.

It doesn't matter for the zaptel (since you can set dchan=any_channel) but
in chan_zap.c in asterisk dchannel for t1 cards is hardcoded to by on 24th
channel. You can change that though.

Martin
