CAUTION: Configuring an ATA device (either a single-port analog terminal adapter
or a port on an analog terminal card) 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.
Purpose
The number of the Analog Terminal Card port (1 to 4).
The 3C10117C (Analog Terminal Card) uses a single
MAC address (there was one MAC address per port on
the previous model of the ATC, the 3C10117). To specify
a port on the card, you must enter a channel number (1
to 4) in this field.
If you are modifying a port on a 3C10117 ATC, this field
contains N/A (not applicable).
If you are modifying a port on a 3C10117C ATC, this
field contains a port number (1 through 4).
A name to help identify this ATA.
Enables the Silence Suppression feature, which reduces
network traffic by replacing a period of silence with a
small silence indicator packet.
Determines whether calls made to or from the telephone
attached to this ATA can be recorded.
Enabled — Enables recording for all calls to or from the
analog telephone attached to this ATA or ATC port.
Disabled — Disables recording for all calls to or from the
analog telephone attached to this ATA or ATC port.
Configures the device to operate over a low-bandwidth
link, such as an ISDN line. Do not enable low bandwidth
for a device that is connected through a broadband
connection through a router/firewall device on the
remote end.
Restricts the ATA to support ADPCM audio only.
NOTE: Fax devices require Mulaw audio.
Prevents this device from being used for conference calls.
Alerts the PSTN that voice data must be uncompressed.
Select this to send or receive faxes over ISDN PRI lines.
