It is likely that you either have a grounded connector, possible pinched between a duct or water pipe or, in a previous life, there may have been a 10 VAC transformer connected for a Trimline or Princess telephone that is connected to the pair on which you are working.

Until you can determine WHAT TYPE of metallic fault exists, you cannot begin to clear it.

A digital volt-ohm meter costs about ten bucks. And guess what? It's re-usable AND a tax deduction.

My guess in this instance is that there is an imbalance on the line that isn't present at the NID because it is due to a high-resistance open (faulty splice on one side of the cable pair). That additional bit of inside wiring added to the circuit is just enough to bring out the noise. If it's clear at the NID and not after the inside wiring is connected, you're going to have a hell of a time getting the telco to accept responsibility.

Well I managed to find a 2nd cross connect block in a store room. The first two pairs have the same buzzing sound. Again switch to another pair; the third pair was a good clear dial tone. So I got the user back up. Still not sure where the fault is at, but every time it rains some phone wire in this building goes south.

Again guys ty for your advice.
