Descriptions And Error Codes
EXP-PN does not support demand testing. A demand reset can be executed to perform a
demand reset on a PN by using reset port-network P level 1 or 2 (P is the port
network’s number, and 1 or 2 specifies the reset level).
PN Cold Restart (#955)
PN Cold Restart, or PN Reset Level 2, reset port-network P level 2 is used as a
recovery mechanism for a PN that has been taken out of service. It is executed as a result of PN
recovery escalation when a Warm Restart is not possible, or as a result of a system technician
demanded PN restart. Once a PN has gone out of service, a PN Cold Restart is required to
bring it back into service.
This is the most severe of the PN restarts, and users will experience a service outage. For the
first 30 seconds after the occurrence of an event that requires a restart, every stable call is
preserved (although new calls will be denied). All calls terminating in the PN are then dropped,
and PN users are not able to place new phone calls during the restart. All PN hardware will also
be re-initialized during this restart. The restart takes no longer than 2 minutes with service being
restored much quicker in a typical restart situation.
