BERT Config
Sync Loss
Threshold
(applies to Rx
card)
BCT= 1 byte, value
of 0 to 3
Command or Query.
BERT config sync loss threshold.
0 = 256 bit errors counted in less than 1000 bits o data
1 = low (100 bit errors in less than 1000 bits of data)
2 = med (250 bit errors in less than 1000 bits of data)
3 = high (20,000 bit errors in less than 100,000 bits of data)

BERT Result in
bit errors
(applies to Rx
card)
N/A 7 bytes,
numeric
Query only.
BERT monitor results in bit errors. If bit errors exceed
9999999, then BRE=9999999.
N/A BRE? BRE=xxxxxxx
(see description of
arguments)
BERT Result in
average BER
N/A 5 bytes Query only
Returns the value of the average BER in the form a.b x 10
-c
.
First 3 bytes are the value. Last 2 bytes are the exponent.
Returns 99999 if there’s no sync in BERT monitor. Returns
99.99 if sync loss has occurred.
Example: BER=4.8E3 (BER = 4.8 x 10
-3
)
N/A BRR? BRR=a.bEc

arguments)
