LD 73 — Defining PRI parameters and thresholds (Part 2 of 4)
Prompt Response
SLP mc mt oc ot
BPV n1 n2
CRC n1 n2
FAP n1 n2
RATS 1-(10)-15
2.0 Mb PRI implementation
Description
Slip error count.
Where:
mc = Maintenance threshold slip count, 1- (5)-255.
mt = Maintenance threshold time, default 24 hours.
oc = Out-of-service threshold slip count, 1-(30)-255.
ot = Out-of-service threshold time, default 1 hour.
Bipolar violation error count. Range is 1-(128)-255 for n1, 1-
(122)-255 for n2.
Where:
n1 is multiplied by 16 to obtain the actual count, giving an actual
count range of 16-4080.
Cyclic redundancy check error count. Range is 1-(201)-255 for
n1, 1-(97)-255 for n2.
Where:
n1 is multiplied by 4 to obtain the actual count, giving an actual
count range of 4-1020.
Frame alignment problem error count. Range is 1-(28)-255 for
n1, (1)-255 for n2.
Number of seconds firmware has to check BPV/CRC/FAP for
excessive error rate.
