I've been playing with a dead TC unit for hours now, and I still can't get it working. It has 45A chassis, quad modems, PRI NAC with T1 software, and a Netserver card. At present, it appears to only answer on a channel or two. The rest of the channels get dead air. The telco is reporting not getting a wink back when they test it. (This T1 works fine with other units) I've tried: 1. Setting all modems to default, and resetting them all. 2. Moving all cards from this unit to a spare 45A chassis. 3. Copying config of PRI NAC and quad modems from a working chassis. 4. Removed all but one modem card. Seemed to answer calls fine with one modem card during two hours of bombarding it with calls. 5. Power cycled a dozen times. 6. Set all modems to inactive in Netserver and reactivated them. Any other ideas? I have 6 more quad modem cards I can pull from a working unit, but I don't want to end up frying them somehow. I also have a 186 T1 card I could try swapping in, but I think it has old software, and it may not work with the rest of the software revs. Would swapping out the Netserver card and NMC card possibly help?
