System Technician-Demanded T ests: Descripti ons
And Error Codes
EXP-PN does not support demand testing. A demand reset can b e 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 numb er, and 1 or 2 spec ifies 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 mec hanism 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 demand ed 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 servic e
outage. For the first 30 seconds after the oc currence of an event that requires a
restart, all stable calls are p reserved (although new c alls 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 long er than 2 minutes with service being
restored much quicker in a typical restart situation.
