The ability to do ISDN at 64 KBps, some say that the robbed bit signeling is "dirty-er" then out of bands messageing on the D channel. Paul D. Farber II Farber Technology Ph. 570-628-5303 Fax 570-628-5545 farber@admin.f-tech.net On Wed, 22 Sep 1999, Stainforth, Matthew wrote:
Part of the reason we're doing this is because CT1 is cheaper but I've never used CT1 before and I'm wondering what other functionality we're going to lose. I gather it will no longer be possible to do busy out the channels from this end and we'll also probably lose ANI too. Are there any other drawbacks that I might be overlooking?

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.

Overnight tonight the telco is changing one of our T1s to channelized T1 from PRI service for testing. 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...
