Description
The defaults are:
CRT (channel reset threshold) 120
TMT (test message threshold) 50
SCT (stop count threshold) 20
Monitoring Period Timer. Period during which NMT messages
must be received before overload is detected.
Number of Messages Threshold. The number of messages
to be received by layer 3 before overload is detected. Note
that this threshold can only be exceeded after the MPT time
has elapsed. Note: If NMT=255 then Overload Protection
mechanism disabled, regardless of OTH/DTH.
Overload Threshold. The number of times overload must be
detected before any action is taken on the link. Once this
threshold is exceeded, the link will be temporarily disabled for
LDT seconds. Note: If OTH = 255 and if NMT < 255, overload
will be monitored. Link will be permanently disabled when
DTH is exceeded, as long as DTH is not 255. Note: If OTH
< 255 and NMT < 255, overload will be monitored. Link will
be disabled for LDT time, and brought back into service.Link
Disable Timer. Defines the amount of time in seconds that
must elapse before the link is brought back into service, after
having been disabled due to overload.
