3. To terminate the two UPS power leads (Pins 6 and 7) and, if needed,
the five alarm status leads in the Power/alarm connector, cut all
wires and strip back the insulation. Use a flat head screwdriver (or
similar device) and loosen all the screws on the Power/Alarm
Connector. Insert one wire at a time and tighten the screws to make
an electrical contact.
4. Reconnect the Power/Alarm connector to the bottom of the
Electronics Module.
5. Tie Wrap the wires to the tie-wrap anchors just below the
Electronics Module.
6. Replace the rubber grommet.
Step 5: Connect POTS
The telephone service or POTS connection is provided through pivot-
connectors located on the right side of the Electronics Module. These also
provide a diagnostic test point. Inserting an RJ-11 jack (i.e., telephone
cable or telephone test set) will connect the telephone set to the 372E SBU
ONT and also disconnect the subscriber service from the 372E SBU ONT
providing fault isolation to the SBU or premises wiring.
To terminate the POTS connections, refer to the figure in the next column,
and complete the following:
1. Remove the rubber grommet from the housing and insert the POTS
cables through the grommet.
2. Trim each wire to length. Identify each pair in the service cable.
3. Flip the pivot connector to the “up” position.
4. Insert the appropriate wires
TIP (green) and RING (red).
5. Flip the pivot connectors to the “down” position.
6. Replace the rubber grommet in the housing.
Step 6: Install Ethernet and DS1 Connections
The SBU ONT supports 2 Gigabit operations. The cable used should be
rated CAT-5 or 6. To install the Ethernet and DS1 connectors, refer to the
figure below and complete the following steps:
1. Route the cables for the Ethernet and DS1 through the same open-
ing as the POTS cables.
2. Trim back the jacket of the subscriber Ethernet cable and connect the
4-pair twisted wires to the RJ-45 Plug using an RJ-45 crimper. The
Ethernet Pin Out table below lists the individual pin out
designations.
3. Insert the terminated RJ-45 jack into the appropriate
ETHERNET
1–2
socket on the 372E SBU ONT.

4. For the DS1 connection trim back the insulation on the subscriber
DS1 cable and connect the wires to the RJ-45 connector using an RJ-
45 crimper. Connect the DS1 cables per the table below.
5. Tie wrap all cables to the appropriate Tie wrap anchor points.

TELEPHONE TROUBLESHOOTING:
1. Identify the bad line (POTS 1-8).
2. Plug any working phone into
the appropriate jack.
If the telephone works, the unit
is functioning normally.
If the telephone does not work,
contact your service provider.
3. Remove the telephone from the
POTS jack.
