Application

The NID-01VTJ splitter provides single line xDSL signal separation from the voice line within the customer’s residence.
The NID-01VTJ also provides an RJ11 test access port, which is used to verify the connection between the customer’s
telco box and the central office.

Preparation

The NID-01VTJ does not require an earth ground.
Use only 22AWG, 24AWG or 26AWG solid conductor wire.

Instructions

Snap in the NID-01VTJ into the customer side of the Telco Box. The NID-01VTJ is designed to fit into most major
boxes.

The NID-01VTJ has four connections:

 Modem – customer’s xDSL modem
 Line – the incoming line
 Phone - customer’s telephone
 Test Jack – verify connection to central office

If the wires have been previously used, cut-off
approximately ½” from the end, before inserting into
the IDC (Insulation Displacement Connector) on the
NID-01VTJ.

Making IDC connections:
Push each IDC away from you, until it swings open
and stops.

Carefully observe the proper orientation of the Tip­Ring leads. Do not remove the insulation from
the wire and maintain the wire twist. Insert each
pair of wires into the appropriate IDC about ½”.

Press the IDC closed, until the IDC latches lock into
place. It will take some force to close the IDC, with
the thicker wire gauges taking more effort.

Testing

To test the NID-01VTJ for correct operation, connect a phone to the phone jack and lift the handset - you should
hear dial tone.

The modem status light should be illuminated indicating xDSL service. You may have to refer to the xDSL modem
users guide to correctly interpret the meaning of its status indicators.

Once tested, secure the wires.
