Clear this option to have the MultiPASS printer remain in answering
machine mode even if no send fax signal is detected. If no sound is
detected by the MultiPASS printer (such as the caller speaking to
leave a message), the answering machine disconnects.
Remote Receive
You select this option so that you can set the MultiPASS printer —
with the telephone handset or from a telephone extension — to
receive a fax if an incoming call is ringing on the MultiPASS printer.
If you select this option, you must assign a remote identification
number that signals the MultiPASS printer to receive the fax.
Remote Identification Number
If the Remote Receive option is selected, you assign the identification
number you will use to set the MultiPASS printer to receive a fax.
DRPD Switch Options (U.S. only)
You can select this option if you subscribe to the Distinctive Ring
Pattern Detection (DRPD) service through your phone company. You
then specify each ring pattern you have been assigned, with its
associated action, fax ID, and fax number.
When you select this option, the MultiPASS printer's receive mode is
automatically set to receive both fax and telephone calls.
Ring Pattern (U.S. only)
If you subscribe to DRPD through your phone company, select the
ring pattern assigned to each phone number by your phone
company: Normal (single-ring), Double (double-ring), S-S-L (short-
short-long ring), S-L-S (short-long-short ring), or Other.
Action (U.S. only)
If you subscribe to DRPD through your phone company, select the
call type to be received for each selected ring pattern. Typically, you
would specify telephone calls for one ring pattern and fax calls for
the other ring pattern. However, if necessary, you can specify that a
selected ring pattern switch between receiving telephone and fax
calls.
