Trying to get out of a potential nightmare. Power generating plant built between the 60's and 80's has an extensive copper wiring plant between an old telco CO that once hosted a DMS-100 switch for Centrex (since replaced with a Nortel 81c), that connects out to the various buildings on site.
Issues with bad pairs are commonplace here - most likely due to two generators kicking out 345kv out the grid 24/7, and Sidekick stress tests are unfavorable for many pairs I come across.
We have a large unused block of pairs - about 1000 - that the telco never used to connect one telephone room to another. Plan is to add 400 more phones - and management is insisting on using existing copper - rather than go with fiber remote gear to bring over to the other telephone room.
Am I right to assume that unused pairs over a period of time - even if they've never been used? Or am I reading too far into the Sidekick test results?
80% of the the unused pairs failed the stress test (that is what the Sidekick says is bad for spans of 2,300 feet - anything over 17db) - and while they may be useable, it'll just create headaches galore during implementation and trouble tickets down the road.
That and the BIX frame where the Nortel PBX is located is one of those back-to-back deals (feepairs on one side, PBX on the other - hate those things).
Seriously trying to avoid what management thinks I should do and sell them the more costly fiber remote option for the sake of quality and reliability (which in the long run will prove to be even costlier).
Thanks.
