Verifying an Analog Terminal Adapter or the ATA Port

operation, expect lower quality voice calls on that port. If you configure
the port for voice calls, the performance is not optimized for faxes.
Using Power over Ethernet with a 3C10400B ATA
The NBX Analog Terminal Adapter 3C10400B meets the IEEE 802.3af
standard for Power over Ethernet and can accept power directly from an
802.3af-compliant power source. Earlier models of the ATA, 3C10120B,
require an AC power converter due to their power requirements.
The table describes how to connect a powered Ethernet cable to a
3C10400B Analog Terminal Adapter.
Verifying an Analog
Terminal Adapter or
the ATA Port
After the NBX system has discovered an Analog Terminal Adapter or the
ATA port, you can verify that the port has been properly discovered and
see which extension number the system has assigned. The system assigns
the next lowest available extension to the analog port.
To verify that the NBX system properly discovered the ATA:
1
Log in to the NBX NetSet utility using the administrator username and
password.
2
Click
Telephone Configuration > ATA
.

power source
Connect the powered Ethernet cable directly to the
telephone’s Ethernet connector. No separate power
connection is required.
3Com Ethernet Power
Source:
■
3C10220 (12-port)
■
3C10222 (24-port)
The 3Com Ethernet Power Source predates
802.3af. Any NBX device can be powered
by a 3Com Ethernet Power Source if you
use an 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 (labeled
LAN
) and power connection
(labeled
).
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).
