CO Ring Detect
The System incorporates timers for Ring-On and Ring-Off durations to assure proper alerting.
When the duration of the Ring Signal exceeds the Ring-On Timer, alerting will start. When the
Ring is not present for a period exceeding the Ring-Off Timer, alerting will stop. This allows the
System Ring cycle detection to be matched to the many and varied PBX systems.
CONDITIONS
- Ring-On time and Ring-Off time are assigned on a System basis.
- The CO Ring Detect is applied to Analog CO Lines only.
