Description
This timer determines how long the DBS 824 attempts to detect an incoming
CO ring cycle. To ensure that the DBS 824 can recognize incoming n-unk
calls, set this timer to equal the duration of the ring cycle, including thefirst
"on"
period and the first "off' period.
For example, if the ring cycle for an incoming trunk is 2 seconds on/ 4
seconds off, this parameter should be set to at least 6 seconds to detect the full
cycle.
Lf this timer is set too short, the system will not recognize valid central office
ring signals.
See Figure l-2 below for an example of proper CO ring cycle detection
timing for an incoming pattern of 2 seconds on/4 seconds off.
