PN Warm Restart (#956)
The PN Warm Restart, or PN Reset Level 1, reset port-network P level 1 is used to
restart a PN that has not been taken out of service. It is the least severe of the PN restart levels
and is used in an attempt to preserve the state of the system as much as possible, thereby
reducing user impact. This restart is attempted on a PN if it is still in service, or as a result of a
system technician-demanded PN Warm Restart.
During a PN Warm Restart all calls are preserved including voice, data, and packet calls. Once
an event has occurred that requires a warm restart, service is fully restored within 35 seconds.
