Voice Processing
Plain Old Telephone Service (POTS) uses in-band signaling tones
and currents to determine call status (for example, call request).
Because POTS allows for the transfer of audio signals below 3.3
kHz, POTS systems are also used for modems that allow data
transmission (referred to as dial up connections).
Ethernet Interface
The 424 ONT supports data service through four 10/100/
1000Base-T Ethernet interfaces via RJ-45-style connectors.
Power
Power is provided by a 12 VDC Power Adapter that is included
with the 424 ONT. The Power Adapter operates from a main
power source input of 100 to 240 VAC, 50/60 Hz, with a nominal
output of 12 VDC. The total power consumption with 4 Ethernet
Ports running and both POTS lines off-hook is approximately 15.0
Watts. A connection for an optional un-interruptible power supply
(UPS) is also provided.
UPS
The 424 ONT provides an optional connection for an
Uninterruptible Power Source (UPS). A UPS is a battery backup
system designed to continue providing power when the primary
power source is lost. Power is supplied to the 424 ONT by a local
power source with battery backup that utilizes the AC power at the
customer premises and keeps the battery charged.
INSTALLATION
After unpacking the 424 ONT, inspect it for damage. If damage is
noted, file a claim with the carrier and then contact ADTRAN. For
more information, refer to the warranty.
Installation consists of positioning the 424 ONT either on a
desktop or wall mount, connecting POTS, Ethernet, and power.

To wall mount the 424 ONT, refer to Figure 1 and complete the
following steps:
1. Decide on a location for the 424 ONT. Mount below eye-
level so the LEDs are visible.
Figure 1. Wall Mount Installation
2. Use the keyholes on the rear of the 424 ONT as a template
and mark the wall accordingly.
3. Use a hammer to lightly tap the included wall anchors into
the marks until the threads are close to the wall. You can
also pre-drill holes using a 1/4” drill bit if difficulty is
encountered.
4. Insert either a #2 or #3 Phillips head screw driver into the
recess of the anchor head.
5. Using gentle forward pressure, rotate the wall anchor
counter-clockwise until the collar is flush with the wall.
6. Install four included screws into the anchor heads. Leave
approximately 1/4 inch (6 mm) protruding from the mounting
surface.
7. Slide the 424 ONT over the screws and exert a small
amount of downward pressure to ensure that the top of the
slots are resting on the shafts of the screws.
gNOTE
Alternately, wall anchors are not needed if mounting directly to
wall studs.
Step 2: Connect Telephone
The 424 ONT has two telephone connections labeled PHONE1
and PHONE2 on the rear of the 424 ONT. To connect the primary
telephone line, simply plug the RJ-45 cable running from the
primary telephone unit into the PHONE1 connection on the rear of
the 424 ONT. Any subsequent phones will be connected to the
PHONE2 jack.
Step 3: Connect Internet
The 424 ONT supports four 1 Gigabit (10/100/1000Base-T)
Internet connections labeled GE1 through GE4. To connect the
primary computer to the Internet, simply plug the Ethernet cable

■Do not locate the 424 ONT in direct sunlight or next to any
thermal devices.
Installation Overview
To install the 424 ONT, you will need to complete the following
steps:
■“Step 1: Installing the 424 ONT”
■“Step 2: Connect Telephone”
■“Step 3: Connect Internet”
■“Step 4: Clean Fiber Optics Cable Connections”
■“Step 5: Connect Fiber Optics Cable”
■“Step 6: Connect Power”

Required tools
Standard technician tools and those listed below are required for
installing the 424 ONT:
■Carpenter’s level
■Four #8 Pan Head screws (1 inch or greater in length)
■#2 or #3 Phillips head screw driver
■Drill
■Hammer
■A telephony/data communication test set
■PON power meter with wavelength filtering

Step 1: Installing the 424 ONT
Installation consists of either placing the 424 ONT on a flat
surface, for example, a desk, or, mounting the ONT to a wall.
Desktop Placement
The 424 ONT can sit on a desktop or equivalent flat, stable
surface. Do not place the 424 ONT in direct sunlight or next to any
thermal obstructions.
Wall Mount Installation
gNOTE
Refer to Figure 1 when installing the 424 ONT on a wall mount.

running from the primary computer into the GE1 Ethernet
connection on the rear of the 424 ONT. Any subsequent
computers will be connected to the GE2 through GE4.
Step 4: Clean Fiber Optics Cable Connections
fWARNING!
Do not look into the ends of optical fibers. Exposure to invisible
LASER radiation may cause serious retinal damage or even
blindness. Verify the optical source is disabled through the use of
an optical power meter before handling optical fibers.
Following is a list of suggestions for cleaning fiber optic connec-
tions:
■Always maintain dust caps and dust plugs installed when
connectors or adapters are not mated. Store spare dust caps
in a sealable plastic bag when not in use.
■Avoid allowing unmated connectors to touch surrounding
unrelated surfaces and do not touch a connector or bulkhead
ferrule for any reason other than while performing the cleaning
process.
■Use a fiberscope or videoscope to verify proper cleaning of
connectors prior to mating connecting components together.
■Use an appropriate quality fabric type cleaner and pure alcohol
(reagent grade, 99.5%pure) when cleaning the endface of
connectors. The alcohol can be applied with either laboratory
grade lint-free tissues or with pre-moistened optical grade
wipes.
■Do not use compressed air to clean optical connectors.
To clean the fiber connections, complete the following steps:
1. Remove any dust caps or connectors from bulkhead.
2. Insert a new fabric spiral wrapped cleaning tip into the
ferrule of the bulkhead.
3. Using your fingers, apply a firm pressure to the cleaner as
you twist the cleaner handle two or three times to create a
wiping action of the cleaning tip on the ferrule endface.
4. Discard the cleaning tip after using on a connector.
Step 5: Connect Fiber Optics Cable
To connect the fiber optic cable, complete the following steps:
1. Remove the dust cover from the incoming fiber connector
and the dust cover on the fiber connection on the 424 ONT.
2. Insert the incoming fiber connector in the fiber connection
port until you hear a “click”.
3. Rout the fiber optics cable so that it is free of sharp bends
and crimping.
Step 6: Connect Power
Plug the supplied 12V AC/DC Power Converter into the 12V
connection on the rear of the chassis. Connect the power plug to
a standard 120V AC outlet.
Using an UPS
The 424 ONT can typically use an un-interruptible power supply
(UPS) if desired. Power is supplied to the 424 ONT by a local
power source with battery backup that utilizes the AC power at the
customer premises. The UPS powers the 424 ONT and functions
as a battery backup (BBU) supplying continuous 12 VDC. Refer to
the installation material that is provided with the UPS for instal-
lation details.
Step 7: Connect UPS
Connect the UPS to the 8-pin MOLEX connector labeled “UPS”
located on the rear of the SFU ONT chassis. Figure 2 represents
the MOLEX connector.
Figure 2. MOLEX Connector
The UPS Power/Alarm Connections Table, below, provides a pin-
out of the connector.
gNOTE
If an UPS is being used and the battery is disconnected or
becomes completely discharged, the 424 ONT is not protected
from power outages, and will send a “Battery Missing” alarm to the
OLT.
