residential and business applications. Because Active Ethernet is pure
IP, no transition protocol is required.
The ONT and OLT employ bi-directional Small Form-factor
Pluggable (SFP) connectors for data transmission. To allow for trans-
mission of downstream and upstream traffic on a single fiber,
different wavelengths are used for each direction. Downstream traffic
uses 1490 nm, while Upstream traffic uses 1310 nm.
Using SFPs that are swappable depending on the application, using SFP-
based optics that are specific to the transmit and receive requirement (10
to 80 kilometers). Refer to the Total Access 300 Series Active Ethernet Small
Business Unit ONT Installation and Maintenance Guide
(P/N 612877SBAONT-5).
This Job Aid covers the electronics module and housings listed in the
following table:

CAUTION
!
Do not use a knife to cut the opening in the rubber grommets. This may
result in an excessively large hole and compromise the integrity of the
unit allowing moisture into the unit.
Refer to the illustration on the first page, the illustration below, and the
following steps to connect the ground wire:
1. Remove the rubber grommet from the housing (Step 1).
2. Route a #6 ground wire through the rubber grommet (Step 2).
3. Trim the insulation back 1/2” on the ground wire and attach the
appropriate ground lug.
4. Route the ground wire as shown and attach it to the ground lug on
the back plate attached to the NID.
5. Replace the rubber grommet in the housing.
6. Route the ground wire 12 inches below finished grade by the
shortest and most direct route to the AC power ground system
Multi Grounded Neutral (MGN) of the customer premises. Ensure
the wire is free of any sharp bends.
7. Attach the ground wire to the subscriber premise with stainless
steel half moon clamps or tie-wrap the ground wire to the riser
conduit of the Buried Fiber Drop.
8. Clean the MGN connector with emery cloth to insure a stable
connection.
9. Attach the ground wire from the ONT to the MGN connector with
the appropriate UL approved ground clamp/fitting.
10. Coat the connection with a metal corrosion preventative.
11. Attach a Warning Ground Tag to this grounding connection.
Power/Alarm Connections
NOTE
Wiring the Power/Alarm connector improperly could damage the SBU.
The ONT is supplied with a 7-pin Power/Alarm connector. To make
connections from the Uninterruptible Power Supply (UPS) to the Power/
Alarm connector, refer to the illustration on the first page, the illustration
below, and Power/Alarm Connector Pin-Outs table on the following page
and complete the following steps:
1. Remove the Power/Alarm Connector by pulling it out of the Elec-
tronics Module.

Required Tools and Supplies
Standard technician tools and those listed below are required for
installing the ONT:
Carpenter’s level
3/32” screw driver for connecting ONT power
5/32” hex tamper-proof bit
RJ-45/RJ-11 crimper
A telephony/data communication test set
PON power meter with wavelength filtering
Fiberscope or videoscope
Three #10 screws and appropriate surface anchors for mounting the
ONT
Assorted tie wraps for securing cabling and wiring
For fiber optic connections, the following are required:
Fiber Optical Fusion Splice Tools
Fiber optics cleaning materials
Included with the ONT packaging are fiber cable management and strain
relief, a fiber connector, and electronics/optics.
Mount the Enclosure
Refer to the illustration below and complete the following steps to mount
the enclosure:
1. Choose a vertical surface near an approved ground and away from
any water source. The subscriber should have easy access for test-
ing.
2. Use the top and side external mounting holes as a template to mark
fastener locations. Use a level to ensure the unit is level to prevent
warping. For an indoor mount, prepare the mounting surface by
attaching a 3/4 inch plywood board to the wall studs. This provides
long-term stability for the ONT.
3. Pre-drill the marked locations and install fasteners or anchors
appropriate to the mounting surface (each anchor rated to 18 lbs or
8.2 kg minimum).
4. Mount the ONT.

2. Remove the rubber grommet from the housing and insert the
Power/Alarm Connector cable through the grommet.
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, trim
back the insulation on all wires. Use a flat head screwdriver 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 using the tie wrap anchor points just below the
Power/Alarm Connector.
6. Replace the rubber grommet.
POTS Connection
The telephone service or POTS connection is provided through pivot-
connectors located on the right side of the Electronics Module. The RJ-11
jacks are for test purposes only. Inserting an RJ-11 jack (i.e., telephone
cable or telephone test set) will connect the telephone set to the ONT and
also disconnect the subscriber service from the ONT providing fault
isolation to the SBU or premises wiring.
To terminate the POTS connections, refer to the figure below and
complete the following:
1. Trim each wire to length. Identify each pair in the service cable.
2. Remove the rubber grommet from the housing and insert the POTS
cables through the grommet.
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.

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 ONT.
For the DS1 connections, refer to the illustration above and the table
below, and complete the following:
4. Trim the insulation on the subscriber DS1 cable and connect the

7. Tie wrap all cables to the appropriate tie wrap anchor points.
Fiber Installation
To install fiber to the ONT, refer to the illustration below and complete the
following steps:
1. Remove the cover of the Fiber Tray (P/N 3353312-E) and install the
tray using the two #6 screws (P/N 327600051-E) provided.
2. Route the fiber coming to the customer premise through the rubber
grommet as shown.
3. Trim the insulation on the fiber cable back so there is a sufficient
length of fiber to attach the fiber connector to the end of the fiber
cable.
4. Loosen the cable support clamp and route the strength member
through the clamp. Retighten the cable support clamp.
5. Clean all optical surfaces before and after splicing.
6. Splice the fiber to the fiber jumper cable (yellow) using a Fusion-
Type splice. DO NOT use a mechanical splice as this may create a
reflection at the splice point.
7. Connect the fiber jumper cable to the Optical connector at the
bottom of the Electronics Module.

Local Power Source Wiring
The ONT needs to be powered by a UL Listed Power Supply suitable for
the application with Output at Local Power Supply (LPS) Levels.
Install the UPS
Installation of the Uninterruptible Power Source (P/N 1187735G1) 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 Uninterruptible Power Source (UPS) cable that runs from
the ONT to the Power/Alarm connector of the UPS via the cus-
tomer provided PVC conduit (or method used by your local tele-
phone company practice).
2. Swing the electronics module closed and tighten the security screw
with the 5/32 Hex tamper proof bit. Do not exceed 20 in lbs of
torque.
3. If necessary, tie wrap both the #6 ground wire and the UPS cable
run to the Buried Fiber Drop riser conduit.
NOTE
Refer to the Total Access 300 Series Small Business Unit Active Ethernet ONT
