Reset Pnc Interchange - Avaya S8700 Maintenance Manual

Maintenance Commands

reset pnc interchange

reset pnc interchange [override-and-lock]
NOTE:
This command does not work like other reset commands. Instead of
resetting or initializing hardware, a PNC interchange is executed. Before
entering this command, look at the states of health of the two PNCs with
status pnc .
This command executes a PNC interchange on a critical-reliability system
(duplicated PNC). The standby PNC becomes active and assumes control of
active call processing, and the active goes to standby. If the standby PNC's
health is equal to or better than the active PNC's, no service disruption takes
place; all stable calls and links are preserved. Some unstable calls may drop.
Both demand and spontaneous PNC interchanges are prevented by the following
conditions:
The standby PNC is busied out.
The PNCs are locked by means of the set pnc lock or reset PNC
override-and-lock commands.
For 5 minutes after a spontaneous PNC interchange, or for 30 seconds
after a demand interchange, an anti-thrashing mechanism prevents
subsequent interchanges unless the override-and-lock option is used.
If the standby PNC's state of health is lower than the active PNC's, the
command will abort unless the override-and-lock option is used.
If the standby PNC has not completed a global refresh since it was last
initialized or released, the reset will abort unless the override-and-lock
option is used.
Note the following caution regarding the use of the override-and-lock option.
See status pnc for details of how to obtain and interpret the states of health and
other current information about the PNCs. For a more complete explanation of
PNC duplication and interchanges, see
