Busyouts and PNC-DUP
Busyout pnc
puts the standby PNC in the busyout state. In this condition:
■ Double call set up is turned off.
■ The standby PNC is unrefreshed; existing duplicate call connections are
removed.
■ PNC interchanges are prevented.
Upon release, interchanges are re-enabled and a global refresh of double call
setup on the standby is performed.
When PNC duplication is in effect:
■ An active PNC component cannot be busied-out.
■ A standby PNC component can only be busied-out when the standby
PNC is first busied-out.
■ The standby PNC cannot be released unless all standby PNC
components are released.
Enabling and removing PNC Duplication
To enable PNC duplication, perform the following sequence of steps:
1. Enable administration of PNC-DUP on the change system-parameters
customer-options form.
2. Fully administer duplicate fiber link connectivity. Verify by list atm-pnc.
3. Activate PNC-DUP through the change system-parameters duplication
form. This is not allowed if any component of either PNC (A or B) is busied
out.
status pnc
Displays information about the operational status of both
PNCs including state of health, alarms, busyouts and locks,
and so on.
reset pnc
interchange
Used to initiate a demand PNC interchange. If the standby
is healthy (state of health indexes all zero), there is no
effect on service. Otherwise, calls may be dropped.
set pnc
Used to lock or unlock the active PNC, preventing
interchanges. It does not interfere with double call setup.
busyout pnc
Removes the standby PNC from service. See also the
following section on busyout of PNC components.
