You should be able to use the same code for either a PRI or a channelized T1 on the DSP, just go into the TCM, select the T1 portion of the DSP (top LED below the power LED), click Configure-->Programmed Settings-->Trunk Settings You will see a setting called signal mode, it should be set to robbed bit for a channelized T1 and message oriented for a PRI. Unless the telco is changing other things (ie switch type, etc) that should be the only setting you need to change when the telco changes your PRI to a channelized T1.

I seem to remember that there is different code for the dual T1/PRI cards depending on which service you have but I'm using all DSPs now and I can't seem to have any CT1 specific code for these cards on TotalService. Does the one code base now support both CT1 and PRI or am I missing something? Thanks...
