Connecting the

Analog Terminal

Adapter

After you have enabled the Auto Discover feature, connect the Analog

Terminal Adapter (ATA) to the same network segment as the one on

which the call processor resides. To connect the ATA:

1 Connect the AC power converter provided with the ATA to the power

connector on the ATA. Connect the other end of the power converter to

an AC power outlet.

If you are using a powered Ethernet cable with your 3C10400 ATA, see

the

"Using Power over Ethernet with a 3C10400 ATA"

3C10120B cannot use a powered Ethernet cable due to its power

requirements.

2 Connect a Category 5 Ethernet cable to the ATA RJ-45 connector that has

no icon beside it. Connect the other end of the Category 5 Ethernet cable

to the LAN on which the Call Processor is located.

3 Wait 2 minutes (more on a SuperStack 3 NBX system with many devices)

for the NBX system to discover the ATA.

4 If the ATA is connected to a fax machine, configure the port for fax

usage:

a Open the NBX NetSet utility and go to Device Configuration > ATA.

b Select the ATA from the list and click Modify.

c Enable the check box labeled Fax Machine, then click Apply.

Configuring an ATA port for fax operation optimizes the performance for

inbound and outbound faxes. If you make a voice call using the ATA

device (for example, if you use the telephone portion of the fax machine),

the quality of the audio may be affected. If you make a VTL call using the

ATA device, the audio may be unusable. If you configure the port for fax

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 3C10400 ATA

The NBX Analog Terminal Adapter 3C10400 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.
