Install UPS

Installation of the Uninterruptible Power Source (UPS, P/N 
1187730G1) will be dictated by on-site conditions and local 
telephone company practices. 

CAUTION

!

Use caution when routing wires and cables. Avoid severe
bending and routing over sharp edges. Use grommets when
possible to avoid wear on cable insulation.

1. Install the UPS cable that runs from the SFU ONT to the 

Power/Alarm connector of the UPS via the customer pro-
vided PVC conduit (or method used by your local telephone 
company practice).

2. Swing the electronics module closed and tighten the security 

screw with the 5/32 Hex tamper proof bit.

3. If necessary, tie wrap both the #6 ground wire and the UPS 

cable run to the Buried Fiber Drop riser conduit.

POTS Connection

The telephone service or POTS connections can be made with 
either two-screw terminal bridges, or RJ-11 connectors.
If the two-screw terminal bridges are used the RJ-11 jacks 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

SFU ONT and also disconnect the subscriber service from the SFU 
ONT providing fault isolation to the SFU or premises wiring.
To terminate the POTS lines on the two-screw terminal bridges 
complete the following:

1. Trim each wire to length and strip insulation. Identify each 

pair in the service cable.

2. Loosen the screws from the 

TIP

 (green) and 

RING

 

(red). 

3. Wrap the appropriate wire around the appropriate screw 

and tighten the screws to secure the connections.

POTS can also be connected directly to the RJ-11 jack. In this case 
the two-screw terminal bridges become isolated and are not used.

 Ethernet Connection

If the ONT is going to support up to 1 Gigabit operation (10/100/
1000), the cable used should be rated CAT-6. Strip 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. Insert the termi-
nated RJ-45 jack into the appropriate RJ-45 

ETH 

socket on the SFU 

ONT. The table below lists the Ethernet Connections and related 
services.
