Notes:
While the T1 channel is guarded, it cannot be used for another call until this Guard Timer has expired.
This setting is available only if the Trunk Signal Type is set for “0” (Loop Start) or “1” (Ground Start);
it is not available for DID signaling types.

Trunk Signal Type (pg. 2-87) FF2 2 BSSCC 02 00 Hold (0-3) Hold
Notes:
If this Inbound Ground Detect Timer is set too short, the system may generate false ringing when Tip-
ground is not removed quickly enough at the end of the call.

Guard Timer for Outbound Calls
(all CPCs) - Version 1.0 or higher
Set how long the system guards the T1 channel after a call is disconnected.
The purpose of guarding the trunk is to prevent “glare” (collision between an
incoming and outgoing call).

channel, before the system recognizes it as a valid incoming call.
