I am trying to extend from the customer's master BT outlet (a BT Business Highway panel) to their new office room, via a preinstalled cat 5e outlet, feedingto their patch cabinet. The wiring is all tested and correct but if a phone is connected to the other end, I get a ring trip (ie phone constantly rings). This is not a problem normally experienced by performing this same procedure but fed from a standard analogue socket.

BT have been less than helpful (as ever) so I wondered of any of you guys had come across this problem, and have any suggestions.

Regards,

Chris

You'll have to take the cable from the front of the TA.

Are you running the extension off a digital port or an analogue port ?

I guess as you are experiencing ring trip, it is an analogue port, is it Line 1 or Line 2 of the 2 analogue ports.

Line 1 can be extended from the NTE5a customer extension panel - the NTE5a will be in front of the Highway NTE, i.e. between the Bt network and the Highway box.

Line 1 can also be extended from the port on the Highway box.

Line 2 has to be extended from the Highway box, either cut the end off a DIY extension lead or run the cable and crimp a BT 431a plug on the end.

*Edit* Sorry just re-read your post, you are not getting ring trip which is a fault condition, you are getting continous ringing, check your wiring you have reversed terminals 3 and 5 somewhere in your connections.

Regards

Simon
