Network Terminating Unit
NTE 5 Master Sockets and VDSL Face Plates


The NTE5 is a network terminating point used in the UK.  It connects to incoming and outgoing copper wiring.   These units also act as a demarcation point and provide a method of isolating the customers wiring.


NTE 5A
This socket allows the customer wiring to be kept separate from the PSTN.  The incoming PSTN wires are terminated on screw contacts with the provision to fit a 3 pole GDT over-voltage protection device.

Customer equipment equipment can be connected either via the Line Jack or by hard wiring onto IDC contacts fitted inside the faceplate.

Removal of the face plate exposes a socket which is used for testing the carriers line.  This provides for a clear demarcation point between network and customer wiring. 

Can be surface mounted (with back box) or flush mounted.

Accommodates a single copper telephone line.

NTE5A

 

NTE 5B
The NTE 5B has the same function as the NTE 5A but does not have the Line Jack outlet in the faceplate.  The face plate is just used as a connection for the customer wiring.
 
This NTE was a "secure" version of the NTE 5A and was typically used for payphones or lines at secure locations.

NTE 5C Mark 1
This socket is shaped differently to the older NTE5 sockets in so much as the front is curved in shape.  The front plate is removable without tools and this is done by pressing the clips on either side of the plate.

Wiring connection is by "Cam Locks" which are colour coded.  The ‘Network’ connectors are RED and the ‘Home’ wiring connectors are BLUE.  No tools are required for the connection.

The Mark 1 can be identified by the blue "Cam Lock" cover.

The home wiring is no longer connected to the faceplate, which again makes it even easier to swap according to the service being installed.

NTE 5C Mark 2

An updated version of the NTE 5C.  It can be identified by the "Cam Lock" covers being clear.  Facilitates easy testing of the BT line by removal of the front lower faceplate to reveal another socket, known as the "test socket".

Uses a 2 wire "Cam Lock" connector on the rear connect to the incoming phone line and three wire "Cam Lock" connector on the front to allow the user to connect internal telephone extension wiring.

It is supplied as two pieces (rear plate with test socket, incoming line & extension connectors and front lower plate equipped with BT socket).   The socket can be flush mounted to a standard single gang back box.

The VDSL face plate Mark 4 and G.fast plate can be fitted in place of the supplied front plate.

Dimensions (L) 85mm x (W) 85mm x (H) 35.5mm.

VDSL Face Plate Mark 1
The VDSL unit fits onto a NTE5A socket and uses the original sockets front plate.  Very simple vDSL filtering is offered on this NTE. 

VDSL Mark 1

 

VDSL Face Plate Mark 2
Plug into a standard NTE5A and no rewiring is required as the faceplate fits in between the existing front lower faceplate and the rear of the NTE5A socket.  Centralised vDSL filtering is then provided negating the need for plug in microfilters with an RJ45/RJ11 socket providing the connection for a modem/router.  Alternatively, provision is made for a hard wired connection to the modem via a two way IDC connector on the front.  This faceplate is backwards compatible with all ADSL services & represents the latest and best in broadband faceplates available on the market.  The Mk2 version adds an RF filter for line stability (a filter for small Repetitive Electrical Impulse Noise-REIN) & features differential and common mode filtering performances past 30Mhz.

VDSL Face Plate Mark 3
This faceplate provides the same benefits as the NTE5/BT Broadband Accelerator bell wire filter with the addition of vDSL/ADSL filtering.  There is an IDC connector for connecting directlt to data sockets.  Removal of the front plate exposes this connector.

It is designed to plug into a standard NTE5A telephone socket, so no rewiring is required as the faceplate fits between the existing NTE5 front lower faceplate and the rear of the NTE5 socket.  Centralised vDSL filtering is then provided negating the need for plug in microfilters with an RJ45/RJ11 socket providing the connection for a modem/router.  Alternatively, provision is made for a hard wired connection to the modem via a two way IDC connector on the front.  This faceplate is backwards compatible with all ADSL services.

The Mk3 adds an improved RF filter for line stability (a filter for small Repetitive Electrical Impulse Noise - REIN) and features differential and common mode filtering performances past 30Mhz.

If replacing an ADSL faceplate then the original lower front of the NTE5 socket needs to be retained to fit onto the vDSL faceplate.  If this is not available then a complete NTE5 will have to be purchased as they are not available separately.

Key Features

  • Line: BS6312 approved integrated 431A plug.
  • CCU: BS6312 approved 4 way 401A socket (filtered).
  • VDSL Modem: Direct coupled RJ45 socket (RJ11 compatible) Direct coupled 2 way IDC connector.
  • Designed for self install without the need to disconnect existing extension wiring.
  • Filters all connected voice equipment so negating the need for microfilters.
  • Moulded from V0 rated material colour matched to BT 1P white.
  • Supplied with long length self tapping & machine type mounting screws (compatible with ALL NTE5 socket variants).
  • Differential and common mode filtering performances specified past 30Mhz.
  • Improved RF Filter for increased line stability.

Note: NOT compatible with NTE5C master sockets! Use MK4 VDSL or G.fast for NTE5C sockets.

VDSL Face Plate Mark 4
The Mk4 VDSL/ADSL filtered faceplate is generally supplied with a NTE5C master socket.  Unlike the previous Mk3 VDSL faceplate this design reverts back to the previous style of replacing the lower front half of the master socket (in this case the NTE5C socket - also available separately).  The new design requires no specialist tools to install - the faceplate clips to the master socket & all wiring connections are via cam lock connectors so no IDC tool is required (tool-less IDC connectors).  Centralised VDSL & ADSL filtering is then provided negating the need for plug in microfilters with an RJ45/RJ11 socket providing the connection for a modem/router & a filtered telephone socket for telephones etc.  Alternatively, provision is made for a hard wired connection to the modem/router via a two way cam lock tool-less IDC connector on the rear.

This unit requires a suitable single gang back box.  If replacing an existing NTE5A then this socket will fit onto the existing surface mounted back box.  It is now supplied with the NTE5C Mk 2 master socket which can be flush mounted without any modification to the back box.

This socket combination replaces all versions of the previous NTE5A & all previous versions of filtered faceplate (NTE2000, NTE2005, Mk1, Mk2 & Mk3 vDSL I-Plate).  This faceplate will work with ADSL, ADSL2, VDSL, VDSL2 & G.fast.

The VDSL face plate plugs into the NTE5C.  On the rear of the VDSL face plate are two connectors marked A and B.  This is a "Cam Lock" connector which can be used to wire a stand alone broadband socket.  The output is filtered so no additional filters are required.  The broadband socket can be  a normal socket or a data socket.  This connector does not support the exchange line and no telephones can be connected to it.  Telephone wiring is connected to the front terminals on the NTE5C marked 2, 3 and 5.

Please note that the broadband output from the face plate is from the small socket on the front-plate (and the filtered “A” and “B” internal terminals directly behind it ) only.  This small socket will not support telephones and a plug in filter for broadband.

G. Fast Faceplate
This unit is specifically designed BT G.fast.  G.fast offers speeds that improve on VDSL & VDSL2, currently up to 330Mbps.  The faceplate is identical to the MK4 VDSL faceplate, however the G.fast version uses revised circuit design which improves the filtering up to 106Mhz.  The faceplate features a revised REIN filter.  All wiring connections are made via "Cam Lock" tool-less IDC connectors and provision is made for a hard wired connection to the modem/router via a two way "Cam Lock" connector on the rear of the face plate.

Normally supplied as a complete unit - which includes a NTE5C Mk2 design.

This product requires a suitable single gang back box (surface or flush mount).

This faceplate will work with ADSL, ADSL2, VDSL, VDSL2 & G.fast.

Dimensions (L) 85mm x (W) 85mm x (H) 39mm.
