1. General
The Network Interface Device (NID) (Figure 1) provides a clear interface point for connections to the
telephone system.
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 Access
WARNING: 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.
Unscrew the customer access screw using a slotted screwdriver. Swing open the outer cover all the way to
the left (Figure 1).

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. Installation
Step 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 Hookup
Step 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 identied 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.)
Figure 7
a. Untwist a pair of wires and straighten the ends before inserting into the protector. It is not
necessary to strip the insulation from the wires.
b. Insert the wires into the holes in the USP, until the wires touch the back of the protector.
Step 5: Screw the stuffer back down to make contact. Gently tug on all wires to check connection.
Step 6: Close telco cover by pushing the telco screws back into position.

openings in base (Figure 8), press feet into openings and rotate
telco terminal end of the module onto the ground bar tang until
ground clip is fully engaged.
9. Testing
9.1 Continuity of the Telco Wiring
Step 1: With the stuffer in the down position, insert test clips into the center of the
test holes on top of the protector in the orientation shown (Figure 9).
Step 2: Test per standard company practices.
9.2 Continuity of the Subscriber Wiring
Step 1: Open the line module door by sliding the orange latch to the right. Insert
test clips into the test ports on the subscriber line module in the orientation
shown for each test to check continuity of the entire line module or to
check each line (Figure 10). Move the orange levers to the connected and
