The BT/Openreach "Interstitial ADSL/VDSL Faceplate" was a clever design that was designed to fit onto an existing NTE5 type master socket WITHOUT any rewiring. We were one of the first companies to offer this faceplate & during production we sold literally thousands with zero returns! That was nearly 10 years ago now and as with anything electronic they don't last forever and are now starting to fail. The bad news is production of these units ceased years ago (we DO sometimes have stock available, check out the product page!), the last revision being the Mk3. The good news is a replacement is available!

However, when replacing there is a choice of faceplates available....

The nearest direct replacement is the Openreach Mk4 faceplate (

Unlike the previous version this is designed to fit onto the new NTE5C type master socket, indeed it is supplied as a complete unit (the NTE5C back plate & the Mk4 VDSL/ADSL front plate).

If you don't have any extensions wired there are 2 wires that will need disconnecting from the old NTE5A back plate & reinserting into the NTE5C, don't worry, no tool is required as the NTE5C uses cam lock connectors (pictured top right) :-

If you do have extensions wired these will currently be connected to the old NTE5A's small lower front plate:-

These will need disconnecting & reconnecting to the NTE5C extension connectors (pictured bottom left), so 5 wires in total in this scenario :-

The other choice is to replace the old VDSL/ADSL interstitial plate & small lower NTE5 front plate with the VTE-2015 faceplate (

This single faceplate replaces two old parts, if you have no extensions wired then no wiring is required, simply unscrew what is fitted and replace with the VTE-2015 (screws are provided).

If you do have extensions wired then these will need swapping over to the terminals on the VTE-2015, an IDC tool is required for this (our code IDCT or IDCTP - see here). The terminals are marked 2, 3 & 5 on both the old and new faceplates so this is very easy to do!

The main confusion with the old VDSL/ADSL faceplates seems to be from people not understanding which part is which, proclaiming they need a "front plate" but not realising that is in fact TWO parts, the small lower front plate (which IS still available as a whole NTE5A type socket & the main VDSL/ADSL plate which is discontinued.
