Anyone using Q-Sig for DCS or to an adjunct system? I'm interested in using Q-Sig supplementary services to an adjunct system. This is an s8700 CM3.0 box connected to a Nortel. Both systems support Q-Sig but we haven't had much luck getting the trunks in service. From what I've read, all I need to do on my side is set:

Sig chan - supplemental service protocol = b
trunk grp - supplemental service protocol = b

DS1 board is configured as isdn-pri, connect = network, protocol version = a.

I'll be happy to provide any additional configs to anyone who has a feel for this, thanks..

Just a couple quick questions to start with.

Is the signaling group type h.323?
Have the nodenames been administered at both ends?
I assume the trunk group carrier type is IP.
How are the ISDN parameters set on the route pattern (bottom half of the screen)?
I also assume you know that DCS will not work to a Nortel, the best you will get is UDP.
Since the Nortel is not a public CO switch, try a connect type of PBX which will open up another field to work with.
Last, DS1 protocol "a" is NI1. I do not have my notes in front of me but I believe Nortel uses protocol "c".

Avaya has published some white papers on connecting to a Nortel switch. Check their support web site for any docs about this.

This is an ISDN/PRI, not IP, trunk group. I've got lot's of PRIs connected to this particular switch, we do use the 'a' protocol on the DS1 config with no problem. I realize we won't be using DCS, I mentioned it just as an example. I will try setting the connect field to PBX, I wasn't sure if that was proper or not.
