NFAS PRI?????

[swood89083]

I know the IP office can have multiple PRI's. the question is can the IP Office allow you to share a d channel like you can on the definity. So you would have one pri with 23B + D and then the second PRI would have 24B's using the first PRI for D channel signaling. In the Definity you do this with Signaling groups. Is it possible?

Thanks

Looking through the documentation, I found this:
"PRI T1trunks support both ISDN and Analog emulation. The default setting is 23B+1D and is switchable in the installation software to become a 24B trunk."

So it looks as if you would be able to do what you're looking for, however I've not found any specifics yet on how to do so. (This is from the 3.0 documentation btw)

I believe that the 24B option is Analog emulation
the 23B=1D is ISDN signaling

as far as I kno ther is no way to get the IPo to recieve singanling information for 1 circuit from another.

Maby one of the North American experts can assist further with this one

Better to have 2 separate PRI's with 2 "D" channels, if you lose the pipe with the "D" channel on an NFAS arrangement and cannot have a redundant "D", you are dead in the water. If you lose 1 pipe or 1 "D" channel, out of two, you are still half alive. This makes a big difference to businesses that depend on dialtone for revenue. The Carrier can provision multiple pipes and "D's" into a trunk group with fallover if one fails.
