1611-05: Ringing Signal End Detection Timer
(Ring Stop)
Use this option to set the Ringing Signal End Detection time. If the ringing signal on a line call is interrupted
for longer than this interval, the system assumes ringing has stopped and terminates the call. Set this option
for compatibility with the connected telco or PBX Centrex. If this interval is set to short, valid ringing will
be inadvertently cut off. If too long, the system will leave the call set up even after ringing has stopped.

1611-06: Caller ID Detection Timer
(CID Detect)
Use this option to set the Caller ID Detection Timer. With DSP-based Caller ID, the Caller ID Detection
Timer is the amount of time between the first and second ring bursts that the system can detect Caller ID dig-
its. If this timer is set too long, the outside caller will hear ringing followed by reorder tone. If set too short,
all the Caller ID digits may not be detected. This timer is only used with DSP-based Caller ID. This option
does not apply to COIU PCBs.
