2.0 Mb PRI
X is the slot number of the 2.0 Mb PRI card.
Alternate mode or CRC multi-frame mode
Default or alternate alarms selected
Slip error count,
mc = Maintenance threshold slip count, 1- (5)-255
mt = Maintenance threshold time, default 24 hours, see Note
after Step 3
oc = Out-of-service threshold slip count, 1-(30)-255
ot = Out of service threshold time, default 1 hour, see Note after
Step 3
Bipolar violation error count, 1-(128)-255 for n1, 1-(122)-255 for
n2.
n1 is multiplied by 16 to obtain the actual count, giving an actual
count range of 16-4080.
Cyclic redundancy check error count 1-(201)-255 for n1,
1-(97)-255 for n2.
n1 is multiplied by 4 to obtain the actual count, giving an actual
count range of 4-1020.
Frame alignment problem error count 1-(28)-255 for n1, (1)-255
for n2.
Number of seconds firmware has to check BPV/CRC/FAP for
excessive error rate.
