What does "teed" actually mean in these circumstances?
So, for whatever reason the cabinet is being relocated. This is no mean feat, as is to be done with no loss of service to the punters connected to it.
Before I go off on one of my rambling explanations, lets get my jargon clear, cab 1, the original cabinet and terminations, cab 2, the new one. Cab hole, the underground cable chamber holding all the current cables. Hopefully you are all up to speed with the terms E and D sides.
Cab 2 installed and new ducts run in to the cab hole.
Although records exist, a 'picture' is taken of all the existing terminations in cab1, tracing the jumpers out from E to D.
New cables are pulled in from cab hole to cab2
The existing E and D side cable joints in the cab hole are opened or have joints made in them.
So now the 'teeing' begins.
E side 1 in cab1 is three way crimped to E side 1 in cab2 in the joint in the cab hole. At this point the pair splits in the joint going to two separate points, this is repeated for say the first 100 pairs.
All this is repeated till everything is duplicated in both cabs, then the new jumpers are run from new E to new D's in cab2, once complete, the tee's are cut away.
All this takes time, and lots of it.
Factor in also the new added complication of FTTC cables and additional jumpers.
It could certainly give issues with FTTC services, and may even be the location of the OP's battery fault.
Got that ?
