Advice on new wiring please

Recently had CCTV installed and asked the installer to run some of the surplus external CAT6 cable from the external phone junction box to a purchased MK4 master socket to be fixed internally on the outside wall of the box room now being used as an office. The plan being to abandon all other internal phone wiring present.

Taking off the cover of the junction box I was surprised to see that the internal connection block was not being used as seen in this picture: www.cyberpictures.net/chestnuts/box.jpg

No issues, will just use new jelly connectors. Any suggestions of which of the colours of the CAT6 cable to use and at the master socket which way round on the connection block of the MK4 do the colours go? There will be no further extension wiring.

Helpful responses welcomed.

**you shouldn’t be touching that**

The screw terminals pictured should always be bypassed. HR central.

Use a twisted (together) pair in the Cat6, pair 1 will be blue/white use that.

Which way at the NTE, it doesn’t matter. Just on the back terminals of the NTE.

But of course, unfortunately I understand that Openreach are not making house calls at present so its Hobson's choice to get the service where its needed now while we have to self-isolate.

Thank you for saying to choose a twisted pair, I probably would not have done so If you had not said that.

This task is not complex and should go quite smoothly!

Openreach are making house calls. But install work within properties is being done at a very basic level, first choice being to use the existing fit, second, provide an NTE as close as poss to the external feed, with power nearby.

Was it not possible to run the CAT6 from the A&B terminals on the back of a filtered faceplate, fitted to an existing NTE5, to a socket in the box room? I guess you are perhaps running the CAT6 externally though?

All existing wiring does not use the correct cable; workmanship is poor and clearly installed by someone least qualified to do so. It doesn't even have a master socket (a secondary was fitted) in the hallway! A plugin extension cable to the bedroom is currently used.

I have no doubt that abandoning all existing wiring with a simple external run on the outside of the house to a new 5C MK4 will marginally improve internet speeds.

The ISP said it would be quite a while before an OR engineer could be sent and said there would be charges which were unspecified. Obviously entry into the house would be necessary just to fit the master socket.

One thing to bear in mind is that if your Cat6 cable is going to run outside, it should be external grade. If it isn't, the jacket is likely to degrade with exposure to the elements, particularly sunlight.

Yep, exterior grade CAT6 used. It's not nice to have wiring on the outside of a house for broadband purposes and CCTV but these technological features were unheard of when the house was built. I guess the future will see FTTP arriving at some time and maybe a mobile phone signal. Dream on in this part of rural England.

I'm sure it certainly will

Edit: I would check for a dial tone and do a quiet line test from the new NTE5 test socket before connecting up the router just to be sure that the circuit is OK. Best of luck.

Maybe using external CW1308 cable (not CCA or CCS) rather than external Cat 6 would have been a better way.
