Selecting Regional
Software and
Components
After you complete the hardware installation, you can download your
preferred regional language software and components.
U.S. English is installed by default and cannot be removed. It is used as a
fallback in case another Regional Software Pack fails to load properly.
The Regional Software Packs include:
■
Localized voice prompts heard by callers, telephone users, and
administrators. These are messages that users or administrators are
not able to change by recording a new message, for example,
prompts used for setting up Auto Attendants and voice mailboxes.
■
Default prompts for configurable voice messages. Users and
administrators can record these messages and substitute their
recorded messages for the default versions.

Any NBX ATA can accept power from an AC power adapter. Use the power
adapter that comes with your ATA. On all NBX devices, the power connector is
labeled with the DC power symbol:
Power over
Ethernet
(IEEE 802.3af)
power source 3C10400B Connect the powered Ethernet cable directly to the telephone’s Ethernet
connector. No separate power connection is required.
3C10120B Devices that predate the 802.3af standard can be
powered by an 802.3af-compliant power supply with the
use of the
3Com Network Jack to NBX Phone Power
Module (3CNJVOIPMOD-NBX), which is
802.3af-compliant. The module removes power from a
powered Ethernet cable and splits it into a power jack and
an unpowered Ethernet connection that you connect to
the ATA’s LAN port and power connection.

The 3Com Ethernet Power Source predates the 802.3af standard.
Any NBX device can be powered by a 3Com Ethernet Power Source if
you use and NBX Power Splitter (3C10223 – package of 12). The
NBX Power Splitter removes power from a powered Ethernet cable
and splits it into a power jack and an unpowered Ethernet
connection that you connect to the ATA’s LAN port and power
connection.
CAUTION: You can damage an NBX device by using an NBX power splitter (3C10223) with the 3Com Network
Jack Power over Ethernet Multiport Midspan Solution (3CNJPSE24). Use the NBX power splitter (3C10223) only
with the 3Com Ethernet Power Source (3C10220, 12-port, or 3C10222, 24-port).
