Reroute Balancing When this check box is selected (default), the PVC conforms to the
configured reroute tuning parameters. This means that when the
PVC reroutes during trunk failure, it will migrate back to its
original trunk at a rate and time determined by the configured
reroute tuning parameters.
When disabled, the PVC ignores the switch tuning parameters.
For more information, see the Navis EMS-CBGX Getting Started
Guide.
Bumping Eligibility If restricted priority routing is disabled, select the check box
(default) for the non-real time circuit to become active whether or
not sufficient bandwidth exists. Clear the check box to keep the
non-real time circuit in retry mode until sufficient bandwidth is
available.
If restricted priority is enabled, a non-real time circuit that has been
bumped remains in retry mode until sufficient bandwidth is
available, regardless of the Bumping Eligibility setting (Disabled
or Enabled).
See Appendix E, “Priority Routing,” for more information.
Restricted Priority
Routing
Select the check box (default) to provision new circuits at the
lowest bandwidth priority, regardless of configured higher
bandwidth priority and bumping eligibility settings.
Clear the check box if you want to use the configured bandwidth
priority and bumping eligibility settings for newly provisioned
circuits.
See Appendix E, “Priority Routing,” for more information.
OAM Alarms
(CBX/GX and ATM
CS/IWU modules
only)
Select the check box (default) to use OAM alarms on this circuit.
Uncheck the box to disable OAM alarms on this circuit. When
enabled, the switch sends OAM F5 or F4 alarm indication signal
(AIS) cells out of each UNI logical port endpoint to indicate that
the circuit is down.
Note: For a MPVC, this field is set to disabled and cannot be
changed.
