1611-01: Minimum Ring Detect Timer
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.
