Has anyone built a PRI from Tata Communications? I am struggling with getting it working... Primarily the Digital Link Descriptor and ISDN Protocol.
I know the circuit is E1 and from the carrier's equipment to the Mitel's T1/E1 MMC modules is a straight-thru cable.
What Address for Message Control (A/B), Network termination, E1 Impedence, etc...
I am trying to work with a local vendor through an interpreter but am struggling with it.
Below is what I have setup, I assume I should see something (like a netsync source at least)? The local carrier said the disconnected the cable from the Mitel, connected to their E1 tester and was able to place and receive a call, so the signal should be there. I have tried about every combination of settings I know to get some response but not getting anything. The carrier supposedly told the customer that they need a "modem" to connect it to an IP PBX (the local Mitel vendor tech said he didn't think that was right), but I don't see why an E1 won't work in a standard E1/T1 card in MMC1.
