Nortel4Ever
Vendor
We have a very frustrating situation for both us as the provider and our customer as the end user - An IPO500V2 cabinet with two V2 combo cards whose trunk ports keep failing. We have replaced the combo cards numerous times and the issue keeps happening. The Telco has been out numerous times and tells us that both loop voltage and ringing voltage are within spec.
Back in the Nortel Norstar/BCM days we had issues with certain analog trunk cards and trunk ports on BCM 50s that would "burn out" and Nortel's suggestion was to install 200 Ohm resisters in series with the Tip and Ring on each trunk. This worked and saved a lot of Nortel trunk cards and BCM trunk ports from damage. We have tried the same thing on this IPO but it has not corrected the problem.
Any suggestions anyone has would be appreciated.
