Response to
Query
G.703 Clock
Extension
CEX 2 byte 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)
