Inbound Ground Start Detection Timer
Software Version: CPC-B Version 1.0 or higher
Address: FF1 3# 21# (1-8)#
Description
This timer determines how long a CO Tip ground signal must be present
before the DBS recognizes it as a valid incoming call (4 seconds by default).
When the CO sends a call to a ground-start DBS trunk, it signals the incoming
call by grounding the Tip side of the trunk.
In most cases, this timer should be set to 3 seconds or longer. Otherwise, the
DBS may generate false ringing when Tip ground is not quickly removed at
the end of a call.
