Response to Query
BERT Config
Sync Loss
Threshold
(applies to Rx
module) BCT= 1 byte, value of
0 to 3 Command or Query.
Sets BERT config sync loss threshold in the form x, where:
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 10E-3
Error Insert
(applies to Tx
module) BKE= 1 byte, value of
0, 1 Command or Query.
Inserts 10E-3 BER in the form x, where:
0 = Off
1 = On

BERT Result
in bit errors
(applies to Rx
module) 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 Restart
Monitor
(applies to Rx
module) BRM= 1 byte, value
of 1 only Command only.
Restarts or resets the BERT monitor.
Example: BRM=1
BRM=

BRM@ N/A N/A
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 , where:
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
(see Description of
Arguments)
Built-in BERT
state (applies
to module-by-
module basis) BST= 1 byte, value of
0 and 1 Command or Query.
Sets state of built-in tester (BST) in the form x, where:
0=Off
1=On
