Non-NTE5

This socket could be an old style master socket, or it could be a secondary socket. Openreach should not be installing this style of socket as the master socket when installing a new phone line.

NTE5

This is the 'standard' socket that Openreach will install, it has been the standard since the 1980's. The lower half is removable. Removing the lower half gives access to the 'Test Socket' as well as the connectors.

VDSL Faceplate

With an engineer installed FTTC (aka VDSL, BT Infinity) a VDSL faceplate is sometimes installed. The socket at the top is a RJ11 socket and should be connected to the FTTC modem or router. The Lower socket is a BT telephone socket for a phone to connect to.

Unfiltered Broadband Faceplate (Installed)

This NTE5 has been fitted with an unfiltered RJ11 socket. These faceplates are typically supplied by AAISP if they provide the phone line where no phone calls are provided. The socket is an RJ11 and so a router can be connected without the need for a filter/splitter.
