Emergency Ringdown
If a station remains off-hook for a programmable period, it can be automatically
treated as an Emergency Call and directed to an emergency destination. The station
may have partially dialed a number or have dialed no digits at all. Each station is
programmed with its specific emergency ringdown destination.
A station number or a group pilot number can be specified as an emergency ringdown
destination. In a private network, the station or pilot number must be in the same
network node. Remote emergency destination and door phones are not permitted.
