Linking two Defnity Switches ISDN-PRI

[tbg247]

I am trying to go from a Prologix v6 to a G3R v9.5 PRI. How do I set up the two groups? How do I create the D-Channels? Please advise.

You have to check to make sure you have ISDN-PRI RTU first. That would be in "system customer-options". Then you would add a DS1 (one end would be set for user and one end would be set for network). Then you add a trunk group, type isdn, no members. Then add a signal group, use channel 24 as the D-channel. Then go back to your trunk group and add your members. Tip: make everything the same on both switches (example; trunk group 10, signal group 10 in both PBXs). Good luck!

Thanks for the response. Not really what I'm looking for. I know how to add PRI circuits. I just need to know the precise steps that need to be taken when you are bypassing a carrier class (5ESS, DMS250, etc)switch and generate D-Channels from the Definity. Should I be setting up line-side/network, isdn/isdn-ext, pbx user/pbx network?? Any help is appreciated.

Apparently, the D-channel is not in service when I do a "status sig group", but it passes all the DS1 tests when I do "test board 01xxx".

Any ideas?? Please help.

If everything is set up properly, then busy and release the 24th port. If that doesn't work try busy and releasing the whole board. That will usually bring the d channel up. Is it really passing all the tests, even on the ports? IF the d channel is not up, then the port tests should fail.

The DS1 board has to be set up as Connect: host on one and Connect: user on the other. The host generates the D channel. If requested (depends on DS1 board) the connection type would be PBX, everything else is standard PRI and UDP programming.
