Re: (usr-tc) Channelized T1 vs PRI
Doesn't PRI have some advantages for error checking, etc. Basically it's easier to trace down and correct line noise problems, signal bounces, etc. than a channelized T1? - mike ----------

You should be able to busy out channels just like you did before with a CT1. CT1s also support ANI if configured that way from the telco. The only functionality I figure you will lose is the ability to take incoming 64k clear channel ISDN calls on your Total Control chassis.

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...

Shouldn't be any differences. Possibly if the CT1 is configured with SF, you might not have as much diag info, but if the CT1 is configured as B8ZS/ESF (same framing as PRI), you'd have the same link diagnostics available.
