DESCRIPTION
The Total Access® 372E Active Ethernet Small Business Unit Optical
Network Termination (372E SBU ONT) is an Active Ethernet Fiber-to-the-
Premises (FTTP) ONT built to address the needs of the small business. The
372E SBU ONT includes the following features:
Eight POTS ports
Four DS1 circuit emulated T1 interfaces (for PBX application)
Two 10/100/1000 Ethernet interfaces
The figure below illustrates the 372E SBU ONT inner enclosure.
NOTE
The Electronics Module Cover has been removed for clarity. This cover
swings to the left after the Telco Access screw is loosened.
Optical technology provides a consistent and common approach to
advancing the public communications network.
The optical network consists of an Optical Line Terminal (OLT) located at
the central office (CO) and Optical Network Terminals (ONTs) located at
the customer premises.
To allow for the transmission of downstream and upstream traffic on one
single fiber, different wavelengths are used for each direction.
Downstream traffic uses 1490 nm, while upstream traffic is carried on
1310 nm. The ONT employs optical diplexers to separate the
wavelengths.

3. Trim the insulation back 1/2” on the ground wire and attach a #10
ground lug.
4. Route the ground wire as shown in the figure below and attach it to
the ground terminal post just below the Electronics Module.
5. Replace the rubber grommet in the housing (Step 3).
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 premises 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 372E SBU 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.
Step 4: Connect Power and Alarm Cables
NOTE
Wiring the Power/Alarm connector improperly could damage the SBU.
The 372E SBU ONT is supplied with a 7-conductor Euro-style Power/
Alarm connector. To make connections from the UPS to the power
connector, refer to the figure and Power/Alarm Pin Out Table below and
complete the following steps:
1. If necessary, remove the Power/Alarm connector by pulling it out
of the electronics module.
2. Remove the rubber grommet from the housing and insert the
Power/Alarm cable through the grommet.

Installation Steps
To install the 372E SBU ONT, complete the following steps:
Step 1: Mount the Enclosure
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 372E SBU 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 372E SBU ONT.
Step 2: Install the Electronics Module
The Electronics Module has a protective cover that prevents access to the
POTS, Ethernet and DS1 connections. To access these connections, loosen
the Telco Access screw on the protective cover.
Refer to the following illustration and procedure when installing the
Electronics Module in the Enclosure:
1. Align the slots on the reverse of the Electronics Module with the
tabs on the Enclosure.
2. Slide the Electronics Module on to the tabs and align the Screw Slot
with the Threaded Hole.
3. Secure the Electronics Module using the #6 (PN 3276003003-E)
screw provided.
CAUTION
!
Do not use a knife to cut openings in the rubber grommets. This may
result in an excessively large holes and compromise the integrity of the
unit allowing moisture into the unit.
Step 3: Install Ground Cable
Refer to the figures below and install the ground connection by
completing the following steps:
1. Remove the rubber grommet from the housing (Step 1).
2.
Route a #6 ground wire through the rubber grommet (Step 2).

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.

NOTE
Refer to the Total Access 372E SBU ONT Installation and Maintenance Guide
(P/N 61287723G1-5) for a list of SFPs used with this ONT.
CAUTION
!
Use caution when routing the fiber optics cable. Avoid severe bending and
routing over sharp edges.
Local Power Source Wiring
The 372E SBU ONT needs to be powered by a UL Listed Power Supply
suitable for the application with Output at LPS Levels.
Step 8: Install UPS
Installation of the Uninterruptible Power Source (P/N 1187735G1) will be
dictated by on-site conditions and local telephone company practices.
1. Install the Uninterruptible Power Source (UPS) cable that runs from
the 372E SBU ONT to the Power/Alarm connector of the UPS via
the customer provided 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. 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.
