When installing a fax machine with a single-port Analog Terminal
Adapter, consider the following points:
A fax machine requires twice the bandwidth (160 Kbps) of a voice
■
device.
A fax machine must be configured to use Mulaw compression.
■
Problems encountered receiving or sending faxes could indicate
■
network traffic issues.
Some PC faxes or modems may not work properly due to the very low
■
latency requirements of such devices.
The most effective way to install a fax machine is to install it using an
■
ATA connected to an uplink card or hub card in the NBX system, or to
use a dedicated switch port for the ATA connected to the fax machine.
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.
