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.
I
NSTALLATION
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.
