CO Line Release Guard Time
To assure that the PSTN switching equipment has sufficient time to restore to the Idle condition,
the System will hold CO Lines in a Busy State to Users after release of a CO Line by a Station.
The time between Station disconnect and when the System changes the CO Line status from
Busy to Idle is the CO Line Release Guard Time. If CO receives ‘Release Ack’ signal from
PSTN before Release Guard Timer expired, then the CO line is released instantly.
