Description
Use this program to adjust timers that affect incoming calls on the line (COIU) PCBs.
Options
1611-01: Minimum Ring Detect Timer
(Ring Detect)
Use this option to set the threshold for ring detection. If the ring signal is longer than this interval, the system
interprets the signal as valid ringing. If the signal is equal to or shorter than this interval, the system ignores
the ringing. Be sure the value you enter is compatible with the local telco. If you set this value too short, the
system may detect line spikes and anomalies as ringing. If too long, the system may not properly interpret a
valid ringing signal.
