Update: 2 more Nortel techs looked at the system, both of these tech were from AT&T. The first one struggled and called in another engineer who I was told was one of their most experienced Nortel techs. He looked at the situation, could not make it work either, and thinks there is something...

Update: Had a 3rd tech that is supposed to be versed in Nortel look at the setup today. He said the dchannel messages probably weren't showing up because the NI2 protocol is meant to work with a CO type of connection, not a connection between devices like this. He didn't seem to think my...

I will try the DMS100/S100 just to see if it would work. My AudioCodes has two DMS100 options: T1 DMS100 ISDN T1 DMS100 Meridian ISDN Generally, I try to stay in a recommended/supported setup, so even if I get some functionality this way, I still think I need to get the upgrades and do QSIG...

OK, I don't know if this is the answer for certain but I may know what is wrong now. Put shortly, I have an IT vendor and a PBX vendor, and it appears neither of them have the full picture. The IT guys were supposed to do the AudioCodes and Exchange UM side, while the PBX guy was supposed to...

Thanks again everyone for responses. The gateway device is also set for NI2. My PRI for telephone calls is NI2 and I see messages on it. My main Nortel guy seemed sure the problem was in the PBX. His logic was basically that the process was never getting far enough to be the AudioCodes...

Dial 8303 and I get dial tone, which I think is what I'm supposed to get. I thought after that, I'm supposed to be able to dial anything (even if it's not "real") and with the dchannel msgi msgo enabled, I should "see" it try? Instead, I see nothing, and after a few moments, I hear a busy...

Sorry, I know there are probably many Nortel fans and I apologize if I seemed to bash them. This phone system has for the most part been very reliable. I am just very frustrated because I'm completely out of my element here, and the costs seem way out of line. I was told that since I don't...

Thanks for the input, DocVic. As stated above, I have been trying to dial the access code directly and I never see any d-channel messages when I do. Regarding the carrier/loopback plug, I didn't want to over-complicate the problem with too much information. I'm wanting to use this PRI to...

Alberto111, I am not sure what you mean about TGAR? If there is some specific command I can input that will help, I will be glad to do so. I Google searched TGAR and it appears to be relating to call restrictions. I know that the Nortel tech I had onsite who tried to get this working...

Sorry, correction, dchannel 12 is used by the signaling server as part of an h.323 trunk to another office. I don't think that's relevant but I wanted to provide correct info.

I'm having trouble capturing the output. I'm trying to source a serial adapter since this this system uses 25 pin and I only have 9 pin ports on my computer. Then I will be able to easily provide exactly what I'm seeing. But when I ld 96 and stat mon, I see something like: DCH MON ON DCH 004...

Ah, ok I was logged in the web interface and CLI simultaneous, so that explains the overlay issue. I changed the DSEL of the RDB to 3VCE, and still when I dial the access code and an extension I want to send over the new PRI, I see no messages. If I understand correctly, I should be able to ld...

I did ld 60, stat 3 and all channels are idle (except 24, which I thought was correct). I did ld 96 and stat dch, it shows to be established. DSEL for the RDB is set to VCE. I'm not sure how to change to 3VCE from the command line, but I can choose from a drop down box in Element Manager and...

We first tried slot 6, then moved it to slot 3, only in the first cabinet. The card itself is fine, btw. We physically swapped it with the working PRI setup and it functioned fine. Working TMDI card is in slot 1, slot 2 has an MC-32, and slot 3 now has the new PRI card.

I'm not a guru on the Nortel system by any means, but we have this dinosaur and I'm trying to add another PRI connection to it. It seems that no outbound communications make it to the D channel. If I enl msgi and enl msgo, then dial the access code, I see nothing. What seems crazy to me is...

Doh, sorry. Thanks for the redirect.
