BT Telephone Master Sockets

[plugwash]

NTE5 master sockets come in two peices. The front peice you show in your picture and the back peice. Incoming phone wiring connects to the back peice while extension wiring connects to the front peice.

Which part is actually broken? just the front peice you show in your picture or the back peice as well?

You can buy unbranded NTE5 boxes from reputable suppliers but if you have to replace both peices (the front peice doesn't carry any branding) than fitting an unbranded one may cause you issues with BT in future depending on how much of a jobsworth the BT guy is. http://cpc.farnell.com/1/1/52124-nte5-socket-5a-r20-7983-psid-pressac.html

There are lots of listings on ebay for BT/openreach branded NTE5s but as bernard says there is a high chance that they are either counterfeit or stolen.

perhaps they're fake, but theres no guarantee the overpriced maplin part is actually any better!

The NTE5 doesnt do any filtering of ADSL does it? Thats done by a seperate filter, be it a "micro-filter" dongle or an interstitial plate in front of the NTE5?

The "micro filter" between phone socket and a phone blocks the ADSL signal to prevent it being heard in the telephone ear-piece. This requires a micro filter for every telephone.

All NTE 5 front plate filters do the same function for the voice phone wiring connected to the filtered ( non ADSL ) connections. This removes the need for a micro-filter at every telephone. Also and more important it separates the voice phone wiring from the wiring between NTE 5 and the modem / router and this separation of ADSL from voice phone wiring prevents any stubs in the voice phone wiring from having any significant effect on the ADSL signal.

( A stub is a cable that branches off from the main cable, the equivalent to a dead end side street from a main road ) Some of the ADSL signal will go down the stub, be reflected at the dead end and return to the main highway after a delay ( the time to travel along the stub ). The modem see the signal followed by an echo ( from the stub ) and this degrades the ADSL signal as seen by the modem / router

can get them off ebay

The standard front plate supplied with a NTE5 does no such thing.

You can get replacement front plates that do but they are an optional extra, not standard issue.

I did say

NTE 5 front plate filters

Perhaps I should have said "A replacement front plate for NTE 5 with filters installed ""

Sorry I misread your post and missed the word filters.

Let's keep it simple and just get grandad back on the phone.
You need a basic NT5 box with a single socket on the front of the front plate and a set of IDC connectors on the back of the front plate
The NT5 splits so that the lower front plate half pulls out from the back half that is screwed onto the wall box.
There is the main incoming cable from BT that has two wires connected to the A*B terminals on the backplate. Get that fitted first.
There is the cable going to the house extensions. (White in your photo) Connect the wires in it to the same numbered connect ions on the new front plate. only 2 3 & 5 actually matter,
Solved and back to pre-existing.
NT5 available anywhere in adequate quality.
Only if broadband ADSL is used do you need to worry about filters and the better options of inbuilt NT5 filters
Best to ask in alarm & phone forum

Just flag down a BT van and offer the bloke a tenner to put it right!
