Ring On / Ring Off Timers
Description
The Ring On Timer, Mode 05-02-07, determines the minimum amount of time that ringing voltage must be
applied to a CO line for the Hybrex digital telephone system to identify a line as having an incoming call.
Any ringing signal that does not meet or exceed the minimum time defined will be ignored. This is useful
in applications where there is a significant amount of noise present on CO lines that could cause false
ring signal.
The Ring Off Timer, Mode 05-02-08, determines the maximum time that a CO line will ring without further
ringing voltage from the Central Office.
The combination of these two timers provide the ability to "fine tune" the Hybrex digital telephone system
to work with Central Offices of varying ringing cadences.
