The local telephone company installs the NID on your premises and will maintain service to this point. you, the customer, are responsible for installing your telephone equipment and connecting the telephone wires to the NID. 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.

2. Terminal AccessWARNING: DO NOT open 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 module by sliding the orange latch towards the hinge and lifting up as shown in Figure 2, to disconnect electrical connection to wiring.

NI-3012 Network Interface Device — Telephone Company Instructions

The model NI-3012 Network Interface Device (NID) (Figure 5) is designed to allow up to 12 telephone lines to be installed. It is equipped with a Universal Line Module (ULM) and Universal Station Protector (USP) which provide Telco/customer termination, line protection, and optional Telco electronics in one unit. The unit may be upgraded by adding additional lines as required.

6. InstallationStep 1: Remove existing protector and

enclosure from building, if installed.Step 2: Select desired mounting location.

Select appropriate mounting features for secure mounting: external mounting ears or vertical conduit mounting.

7. Service HookupStep 1: Open telco cover using a pin and hex tool to turn the

two telco screws one-quarter turn. Remove the middle rubber grommet and pierce with sharp object (Figure 6). Feed drop wire and ground wire through grommet and replace grommet.

Figure 6

NOTE: Drop wire terminals are Insulation Displacement Connectors (IDC); wires need not be stripped. The terminals are identified with a “T” for tip and an “R” for ring.

Step 2: Connect ground wire according to local code or practice using a #6 AWG ground wire.

Step 3: Unscrew the stuffer on the USP until it is fully open (Figure 7).

Step 4: If using 22-24 AWG wire, it is necessary to use the wire guide to facilitate proper wire insertion. If wire guide has been misplaced, contact Corning Customer Services to order replacement guides. If using 18 AWG wire, remove the wire guide from the protector holes. (It is recommended to retain the wire guide in case it is needed later.)
