Description of Arguments
Command or Query. (FAST option)
Sets or returns 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: <0/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.
