I intend to make some changes to the internal phone/broadband wiring in my 1985 property. I have a couple of questions before I go ahead, and I wonder if any of the esteemed forum members can assist me.
The current wiring scheme is as follows:
The BT drop cable enters the house into the rear of a flush-mounted 1-gang back box.
In the box, behind a blanking plate, two wires are gel-crimped to CW1308 cable (approx 2.5m long).
Then a LJU2/1A master socket.
Then CW 1308 cable (approx 15m).
Then a LJU2/3A secondary socket in the lounge (modem, router & DECT phone plugged in here).
Then CW1308 cable (approx 8.5m).
Then a LJU2/3A secondary socket.
(Two computers, NAS & printer are in an upstairs office, connected to the router via a switch and powerline adapters. Other devices connect to the router via WiFi.)
The modem & router are not in an ideal location, but there is no other telephone socket close to a power outlet.
My long-term aim is to relocate the modem or modem/router adjacent to where the drop cable enters the house and run an ethernet cable to the office, thereby eliminating the powerline adapters, but first I would have to install a new power socket. My plan is:
Stage 1: Terminate the drop cable at an Openreach branded NTE5A (2014 vintage) fitted to the back box. Reconnect the internal wiring to this and replace the LJU2/1A with a LJU2/3A. I already have the necessary 'bits'.
Stage 2: Fit an Openreach branded Mk3 interstitial plate to the NTE5A. Re-site the modem (& router) to the upstairs office, and connect to the A&B terminals on the Mk3 using CAT6 cable (approx 27m). Remove the powerline adapters.
Stage 3: Fit a power socket close to the NTE5A, re-site the modem alongside, and use the CAT6 cable from Stage 2 to establish an ethernet connection with the router in the office.
My questions are:
1. I know Stage 1 is not allowed unless I get BT to do it, but is it likely to cause any problems?
2. Will Stage 2 work?
3. Will the Mk3 stop the phone extensions acting as a bridge tap, and if not would there be any benefit from using a VDSL faceplate instead?
4. Will the Mk3 remove the need for a dangly filter on the DECT phone, and if so would it cause issues if I don't remove it? It's behind some heavy furniture, so I would prefer to leave the filter in place if it doesn't cause a problem.
I don't expect any immediate improvement in the broadband speed, as I am already syncing at the full contracted 40/10, and the biggest slowdown is due to congestion on the Vodafone backhaul in the evening. However, I would like the house network to not be a bottleneck for any future upgrade.
Thanks in anticipation,
George
