System Technician-Demanded Tests: Descriptions
And Error Codes
EXP-PN does not support demand testing. A demand reset can be executed to
perform a demand reset on an EPN by using the
reset port-network P level
[1 | 2]
command (P is the port network number, and 1 or 2 specifies the reset
level).
EPN Cold Restart (#955)
EPN Cold Restart, or EPN Reset Level 2, using the command
reset port-network
P level 2
is used as a recovery mechanism for an EPN that has been taken
out-of-service. It is executed as a result of EPN recovery escalation when a Warm
Restart is not possible, or as a result of a system technician demanded EPN
restart. Once an EPN has gone out-of-service, an EPN Cold Restart is required to
bring it back into service.
This is the most severe of the EPN restarts, and users will experience a service
outage. For the first 30 seconds after the occurrence of an event that requires a
restart, all stable calls are preserved (although new calls will be denied). All calls
terminating in the EPN are then dropped, and EPN users are not able to place
new phone calls during the restart. All EPN 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.
