So for circuits that donít require anything from the exchange bar pairs they will maintain a pair just for testing purposes ???
That seems hugely shortsighted (though sadly not surprising) if you ask me.
On SOGEA lines thatís the case already, and the reason is the one Iíve given.
There was some work done in 2013/4 looking at whether test heads in Cabs would cost in, back then it didn't but the economics may change.
The feeling ( not sure it ever got firmer than feeling!) was that you needed a system to routinely / remotely test lines without a truck roll to the cab. This could have been overcome with a modem 'app' but there was intense pressure for any modem to be allowed and this gave OR ( you) no remote vision of the line state. Of course with modem failure the line would have been untestable so "exchange test heads remain" was the answer then.
By 2025 the economics may have changed.
Of course in a vertical monopoly situation this is all easy to solve as the supplier would control the end to end service BUT we will never be back there using copper. Fibre is a different beast until OFCOM mandate unbundled FTTP.
Test heads in cabs sounds very expensive anyway. The FTTC Brandeburg system can and does detect issues like HR faults. It can do so with no E-side.
However proper tests heads are needed to detect earth and battery faults. Openreach does have remote vision of the line at the moment though. All that is required is the OGEA reference for the circuit concerned and a test can be run that will tell you the sync speed, and if thereís a fault on that circuit.
