Carrier-in-
Carrier (CnC)
PMSI Mode
Command or Query. (CnC parameter)
CnC PMSI (Pre-Mapped-Symbol Interface) mode in the form x, where:
0=Idle
1=Redundancy (1:1 or 1:N)
2=Talk
3=Listen
(see Description of
Arguments)
Command or Query. (CnC parameter)
The maximum value that may be entered, in the form xxx, as the CnC Sweep frequency range depends on
the Rx symbol rate as follows:
18ksps to 64ksps: ± 1 to the symbol rate (ksps)/2
64ksps to 389ksps: ± 1 to 32 kHz
389ksps to 2000ksps: ± 1 to 10% of sym rate
>2000ksps: ± 1 to 200 kHz
(see Description of
Arguments)
Command or Query. (CnC parameter)
CnC min/max delay value in milliseconds, in the form xxxyyy, where:
xxx=minimum delay
yyy=maximum delay
Maximum allowable value is 330ms
(see 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.
