Telephone Network Interface

When using your telephone equipment, basic precautions should always be followed to reduce the risk of fire, electric shock, and personal injury, including the following:

  • Read and understand all instructions before proceeding.
  • Follow all warnings and procedures on this instruction sheet or on the product.
  • NEVER install telephone wiring during a lightning storm.
  • NEVER install telephone jacks in wet locations unless the jack is specifically designed for use in wet locations.
  • NEVER touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
  • Use caution when installing or modifying telephone lines.

SAVE THESE INSTRUCTIONS

GENERAL
Exterior of your telephone network interface boxDeregulation has brought about many changes in the telephone industry. A particular concern to customers is defining where the "interface" or "demarcation point" between telephone company and customer responsibility lies.

The Network Interface Device provides a clear interface point for connections to the telephone system.

The local telephone company installs the Network Interface Device on your premise and will maintain service to this point. You, the customer, are responsible for installing your telephone equipment and connecting the telephone wires to the Network Interface Device. If you do not wish to install your own equipment, you may contract with the local telephone or independent company to install the equipment for you.

TERMINAL ACCESS
Interior of your telephone network interface boxUnscrew the customer access screw using a slotted screw driver. Swing open the outer cover all the way to the left (Figure 1).

Warning: DO NOT open the inner cover – It is the responsibility of the telephone company to make the necessary connections under this cover. There is a potential HIGH VOLTAGE DANGER inside.

Caution: To avoid electrical shock hazard when servicing your telephone wiring, open cover of terminal by depressing latch as shown in Figure 2, to disconnect electrical connection to wiring.

WIRING

  • Interior view of your telephone network interface boxLocate terminal to be wired and open cover by depressing latch as shown in Figure 2.
  • Use a sharp object, such as a pencil or pen, to puncture a small hole through one of the holes in the grommet located in the bottom right of housing, as shown in Figure 3.
  • Pull wire through hole in grommet and extend 3 inches past top of box. Route wire to proper terminal. Tuck extra wire in trough of housing.
  • Strip cable jacket back 1-3/4 inches. Be careful not to cut insulation of individual colored wires. Remove 3/8 inch of insulation from individual wires. Pass wires between legs of hinge.
  • Loosen four screws one turn – DO NOT REMOVE SCREWS. Match color of wire to color coded screws. Loop wire clockwise between washers. Tighten screws securely. (Alternate wire colors: Blue/White to Red screw; Blue to Green screw;Orange to Yellow screw; and Orange/White to Black screw).
  • Route wires neatly. Close terminal cover, press until cover clicks closed.
