Description of Arguments
Command or Query. (FAST option)
G.703 Clock Extension in the form ab, where:
a = G.703 Clock Extension Mode
0 = None
1 = TxLock
2 = RxEnable
b = G.703 Clock Extension Interface
0 = T1
1 = E1Bal
2 = E1Unbal
Example: CEX=12 (Sets Tx Lock to E1 Unbalanced)
Notes:
1. Not all CEX modes are valid all the time.
2. For argument a:
If Data Interface (ITF) is G.703, only 0=None is allowed.
If Tx clock (TCK) is not Internal, 1=TxLock is not allowed.
Command or Query.
Tx BERT State in the form x, where:
0 = Off
1 = On
Example: BTX=1 (Tx BERT On)
Command or Query.
Rx BERT State in the form x, where:
0 = Off
1 = On
Example: BRX=1 (Rx BERT On)
Command or Query.
Tx BERT Pattern, in the form x, where:
0=space
1=mark
2=1:1
3=1:2
4=63
5=511
6=2047 (default)
7=2047R (or 2047 Alternate)
8=Mil-188
9=2^15-1
A=2^20-1
B=2^23-1
