G. Distinctive Ringing
Distinctive ringing is an option provided by some telephone companies which permits
extremely accurate routing of calls. When using this feature, you are issued several
telephone numbers while having only one actual telephone line. When dialed, each
number will ring "distinctively". The FAXJACK can differentiate a distinctive ring cadence
from a standard ring cadence and route the call accordingly. "Normal" ring cadences are
routed to the Phone 1 port while distinctive ringing is routed to the other ports.
On "normal" rings, the FAXJACK will still monitor for fax CNG tones and touch tones,
before sending the call to the Phone 1 port.
* Note: If your "normal" ring is less than 1.8 seconds or a double ring, etc., you cannot
use this feature.
When the distinctive ring option is enabled in the FAXJACK, the automatic and manual
answer modes can still be selected. The manual answer mode (dip switch 3 set to on)
should only be used if telephone company voice mail is used on the same line as the
FAX-1000. In the manual answer mode, the FAXJACK does not answer the line
("normal" ring patterns), allowing compatibility with the telephone company provided
voice mail. If there is no telephone company voice mail on the line, the automatic answer
mode (dip switch 3 set to off) should be used.

Automatic Answer Mode
In the automatic answer mode, the FAXJACK monitors the ring pattern of the first CO
(telephone company) ring. If the FAXJACK detects a distinctive ring pattern, it answers
the call and starts ringing the device specified by the distinctive ring pattern. If the
FAXJACK detects a "normal" ring pattern, it answers the call then starts generating
ringback tones to the caller every four seconds, while listening in the interval between
ringbacks for fax CNG tones or touch tones to route the call (see
Operation , section D
for a description of how incoming touch tones can be used to route calls). If fax CNG
tone or touch tones are detected, the
FAXJACK starts ringing the appropriate device,
maintaining four seconds of off time between rings. If fax CNG tones or touch tones are
not detected after two ringbacks, the
FAXJACK starts ringing the Phone 1 port. The
selected port is rung until the ring limit is met (see Operation , section E ).
