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.
