ATA Fax Line Configuration

To support fax on the Synapse system, you should consider where the fax is, and which
telephone line will be used for incoming faxes. Fax line configuration for the Synapse
system differs depending on whether you are using a PSTN Gateway or a T1 Gateway or
SIP Gateway.
For more information about fax configuration and ATA configuration, see the
Synapse Administrator's Guide at

PSTN Gateway

The PSTN fax line can be connected to any FXO port (LINE 1–4) on the PSTN Gateway.
However, trunks for outgoing calls are seized in ascending order (LINE 1 then LINE 2,
and so on). To avoid using the fax line for outgoing voice calls, make the fax line the
highest possible numbered line on the highest numbered Gateway. Use the Fax
Configuration page in the WebUI to select a telephone line on the PSTN Gateway as
the fax line.
If your office has heavy fax volume, the fax line should be a separate dedicated line, and
not part of a hunt group.
Line Appearance mode only — When using Line Appearance mode, you can configure
your fax line in one of two ways.
You can keep the PSTN fax line completely separate from Desksets by not

assigning the fax line to any programmable feature keys on Desksets. That way,
incoming fax calls will never ring at any Desksets. However, in this configuration,
the fax line cannot be used for voice calls.
You can configure the line for both fax and voice. On the Fax Configuration

WebUI page, under PSTN Gateway Fax Line, select the desired line. You can
then assign this line to programmable feature keys on the desired Desksets.
Incoming voice calls on this shared fax/voice line will ring at Desksets after an
8-second delay. This delay is a fax detection period during which the system
determines where to route the call. If the system detects incoming fax tones, it
routes the call through the configured ATA FXS port to the fax machine. During
the delay, the Desksets indicate that the line is in use — the key LEDs are solid
red. If no fax signal is detected after 8 seconds, the Desksets ring.
