Field descriptions:
Example:
If the value for Activation (%) is 5, then the value for Deactivation (%) can be 0, 1,
2, 3, or 4.
Activation (%) This field specifies the percentage of setup events for a
path to become impaired. That is, if the percentage of
setup events for a given path meets or exceeds this
administered value, then it becomes impaired (see
example below). An alarm is raised against an ATM-IMP
when one or more paths originating from that ATM-IMP
become impaired. [Values 1 to 20, default is 4]
Deactivation (%) This field specifies the percentage of setup events for a
path to come out of the impaired state. That is, if the
percentage of setup events for an impaired path meets or
drops below this administered value, then it is no longer
impaired (see example below). An alarm is retired when no
more impaired paths are originating from that ATM-IMP.
[Values 0 to19, default is 3]
Timeout (msec) The maximum number of milliseconds allowed for an SVC
connection to be completed before being counted as
delayed. [Values 250 to 20,000, default is 1000]
Deny Calls Using
Impaired Paths?
This field specifies whether to deny calls that use
connections over impaired paths. If the option is y, then
calls that require a new SVC on an impaired path on the
active PNC are not completed. If the option is n, then those
calls are treated according to current administered
parameters for ATM PNC. [Default is n]
