Channelized T1

[cmesser]

I have a T3 coming into my 7204 router. I use 14 T1s, all timeslots, for data and ipt. For one T1 I would like to use timeslots 1-18 for data and use the remaining timeslots as a voice PRI. Has anyone done this, or is it even possible?

Thanks in advance for any response.

I had a diff scenario with 2 T1. The 1st t1 had 1-8 for fxo voice and 9-24 for data and the 2nd t1 had 1-4 fxo voice, 5-12 CAS, 13-14 fxo and the rest was disabled...although it is not the same as yours, it does give an idea that it may be possible. Below is a snippet:

controller T1 0/0/0

framing esf

linecode b8zs

channel-group 0 timeslots 9-24

ds0-group 1 timeslots 1 type fxo-loop-start

ds0-group 2 timeslots 2 type fxo-loop-start

ds0-group 3 timeslots 3 type fxo-loop-start

ds0-group 4 timeslots 4 type fxo-loop-start

ds0-group 5 timeslots 5 type fxo-loop-start

ds0-group 6 timeslots 6 type fxo-loop-start

ds0-group 7 timeslots 7 type fxo-loop-start

ds0-group 8 timeslots 8 type fxo-loop-start

Hi,

You are talking about CAS here not PRI. I have split the channels in PRI and then used them seperately for diff dial-peers but not for data.

I am not sure if Telco would support this but just in case there is a caveat you can prolly give this config a shot. Let me know how it goes.
