ESCRIPTION

This Job Aid supports the Total Access 324 Indoor 3rd Generation 
Single Family Unit (SFU) Optical Network Termination (ONT). The 
illustration above displays the rear of the SFU ONT and a cut-away of 
the top depicting status LEDs. 

Ports/Connectors

2 POTS Ports

4 Gigabit Ethernet Ports

DC Power Plug

UPS Connector

SC Fiber Connector (located behind the protector panel labeled 
“Fiber Port”. Refer to 

“Installing Fiber”

 on page 2 for installation 

information.)

Resetting the ONT

A reset button is available if the SFU ONT needs to be rebooted. To 
reset the SFU ONT, press the RESET button for 5 seconds or longer. 

WARNING

!

All settings will return to Factory Defaults: Registration provisioning
will be lost.

Voice Processing

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).

Indoor 3rd Generation SFU ONT

Ethernet Interface

The SFU ONT supports data service through four 10/100/1000Base-T 
Ethernet interfaces via an RJ-45-style connector. 

Power

The power feed is 12 VDC. The total power consumption with 4 
Ethernet Ports running and both POTS lines off-hook is approxi-
mately 7.2 Watts.
The SFU ONT uses a standard DC barrel-type connector as a primary 
power source. A connection for an optional un-interruptible power 
supply (UPS) is provided.

Fiber

Fiber is supplied to the SFU ONT using an SC Fiber connection 
located behind a removable protective panel.

UPS

The SFU ONT provides an optional connection for a UPS. An UPS is a 
battery backup system designed to continue providing power when 
the primary power source is lost. Power is supplied to the SFU ONT 
by a local power source with battery backup that utilizes the AC 
power at the customer premises. 

I

NSTALLATION

After unpacking the SFU 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 SFU ONT either on a desktop 
or wall mount, connecting POTS, Ethernet and Fiber, and connecting 
power.
