I am trying to get a PRI tieline installed between the G3 and my voice gateway. Unfortunately the PBX jockey gave me a cable that I believe I have pinned out correctly but, still cannot get the connection to come up. I have 25 pair cable with the PBX ds1 connection to a RJ45 using pair 1,2,4&5. I set the Gateway up using MGCP with DMS-100 protocol, I am using the exact setup I used on a previous Nortel Option 81 setup. Any suggestions would be appreciated.
