Connecting the Analog Terminal Adapter 129Connecting theAnalog TerminalAdapterAfter you have enabled the Auto Discover feature, connect the AnalogTerminal Adapter (ATA) to the same network segment as the one onwhich the call processor resides. To connect the ATA:1 Connect the AC power converter provided with the ATA to the powerconnector on the ATA. Connect the other end of the power converter toan AC power outlet.If you are using a powered Ethernet cable with your 3C10400 ATA, seethe “Using Power over Ethernet with a 3C10400 ATA” next. The3C10120B cannot use a powered Ethernet cable due to its powerrequirements.2 Connect a Category 5 Ethernet cable to the ATA RJ-45 connector that hasno icon beside it. Connect the other end of the Category 5 Ethernet cableto 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 faxusage: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 forinbound and outbound faxes. If you make a voice call using the ATAdevice (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 theATA device, the audio may be unusable. If you configure the port for faxoperation, expect lower quality voice calls on that port. If you configurethe port for voice calls, the performance is not optimized for faxes.Using Power over Ethernet with a 3C10400 ATAThe NBX Analog Terminal Adapter 3C10400 meets the IEEE 802.3afstandard for Power over Ethernet and can accept power directly from an802.3af-compliant power source. Earlier models of the ATA, 3C10120B,require an AC power converter due to their power requirements.
