Command or Query.
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)
Notes:
1) Not all CEX modes are valid all the time.
2) For argument a:
• When Data Interface (ITF) is set to be G.703, Clock Extension Mode is
automatically set to be 0=None. Response is ITF+
• When Tx Clock (TCK) is changed from Internal to Non-Internal, Clock
Extension Mode will be automatically changed to 0=None if it was
1=TxLock. Response is TCK+
Example: <0/CEX=12 (Sets Tx Lock to E1 Unbalanced)
Command or Query.
Valid only for T1 interface (in all modes other thanT1, this is a don't care),
Sets or returns T1 Line build-out in the form x, where
0 = 0-133 feet
1 = 133-266 feet
2 = 266-399 feet
3 = 399-533 feet
4 = 533-655 feet
Example: <0/LBO=2
Command or Query.
Valid only in CDM-570A Compatible Mode (CMO=1).
Sets or returns Tx BERT State in the form x, where:
0 = Off
1 = On
Example: <0/BTX=1 (Tx BERT On)
Command or Query.
Valid only in CDM-570A Compatible Mode (CMO=1).
Sets or returns Rx BERT State in the form x, where:
0 = Off
1 = On
Example: <0/BRX=1 (Rx BERT On)
