Fax/DID
Step by step
Fax/DID
Systems can be equipped with an optional Fax/DID
Module (direct dialing to extensions) for answering ex-
ternal calls automatically, playing announcements and
detecting fax signals. A caller can dial any extension or
enter any digit configured in the Answering Menu and
be transferred to another extension or group. The max-
imum number of calls that can be answered simulta-
neously is 8.
The feature has five modes of operation: Fax only, DID,
Fax/DID, message and Auto Fax. If an S
or TME1 mod-
0
ule is also installed, a fourth connection state is avail-
able: DID for digital lines.
Messages stored with this feature can be programmed
for a second attendant to answer external calls or for a
call forwarding destination for an extension (see call for-
warding, in the User Manual).
Fax mode
In this operating mode, the system detects only Fax sig-
nals. A greeting message is played for all incoming ex-
ternal calls. If the caller wants to send a fax, it can be
sent at the end of the greeting. If no fax signal is detect-
ed within 10 seconds of the greeting message, a sec-
ond message is played and the call is transferred to an
attendant.
DID Mode
In this connection state the interface detects exten-
sions or digits dialed and then transfers the call accord-
ingly. When an external call is answered, a greeting
message is played to guide the caller. The following is
an example of a recorded message: "You have reached
Siemens. Dial the extension number you would like to
reach: 22 for sales department or 23 for technical sup-
port." If no valid MF signal is detected within 10 sec-
onds of the greeting announcement, a second greeting
will be played and the call will be transferred to an atten-
dant.
