Phone extension sockets, Digital Voice and broadband speed

[TallSteve2]

I recently had problem with router. As part of the EE investigations an Openreach engineer tested my line at point of entry into the house. He decided to replace my ancient phone socket with a new Openreach Master Socket 5C.

Router fixed by new PSU, but now will not connect via phone extension point (fine before). Only works through master socket (no electrical outlet nearby). EE "guide" couldn't get his head round this and couldn't see the problem as router working through master socket. He said I need a technical survey at extra charge.

Decided to look online, and I can now see that Openreach engineer did not connect my phone extension cables.

Where to next?

@XRaySpeX . Don't think it was NTE5. More like this

OK, it's an LJU 1 or 2 Master but still has internal terminals to connect Secondaries.

@TallSteve2 A full 5c Master socket complete with the front plate!

5c OR Master socket complete!

Incidentally I have one of these on the window frame upstairs where the extension lead re-enters the house.

[XRaySpeX]

Yes, that's not a Master 5C Mk 4 as @JimM11 has but just the unfiltered 5C.

You last image is just a Junction Box on the incoming line before it reaches the master socket. It has no real significance other joining the incoming cable to your internal circuit.

I have had no contact from EE arranging a technical visit for extension cable reconnection. I am going on holiday. I'll worry about it when I get back. Meanwhile router remains connected to power outlet in kitchen and BB cable trails across floor through kitchen door to master socket.

Update. No contact from EE. I have had the extension socket reconnected privately. Now all hunky-dory........at least until Openreach decide to install Fibre to the Premises when it might all have to be reconfigured.

If the extension cable has been left loose and unconnected then it's easy enough to re-connect it yourself. Just lift up the clear plastic lever on the left of the master socket, insert the two wires and close it firmly. This will penetrate the insulation and make the necessary connections.

The colour code is blue with white stripe to terminal 2, and white with blue stripe to terminal 5. These two terminals are the outer ones of the three in the extension connector.

If you also  have an orange with white stripe wire then this can  be connected to the middle terminal - numbered 3, though this is not required for a broadband connection.

As an aside, it seems very remiss that an Openreach technician could forget to re-attach the extension cable and then express puzzlement when the extension socket didn't work!

Yes, private engineer found extension cable just loose behind new master socket. Cabling was old and there was at least 4 wires of various colours. He sorted it out and checked everything  working at extension socket. Engineers well-honed knowledge will disappear when he retires.
