Description of Arguments
Command or Query. (G.703 parameter)
Tx Ternary Code in the form x, where:
0=AMI
1=B8ZS
2=B6ZS
3=HDB3
Example: TTC=1 (selects B8ZS)
Command or Query. (IDR parameter)
Transmit Backward Alarm enable in the form xxxx, where:
0=Disable
1=Enable Internal (S/W)
2=Enable External (H/W)
Example: TBA=0120
Command or Query. (IDR parameter)
IDR ESC Type in the form x, where:
0=64k data channel
1=2 Audio channels
Command or Query.
Tx LO frequency information in the form xxxxxs, where:
xxxxx is the LO frequency, 3000 through 65000 MHz or 00000 (OFF)
s is the sign for the MIX
Terminal Frequency = LO ± TFQ (see below)
Example: TLO=12000+ (BUC LO is 12GHz, low-side mix)
Query only.
Terminal (aka satellite) Tx Frequency, which is the frequency transmitted to the satellite.
Resolution=100 Hz
Returns 00000.0000 if LO is zero
Example: TTF=11650.2249
Query only.
This command allows remote access to the Aggregate Tx Information rate in the form: ddddd.ddd
Query only.
This command allows remote access to the IP portion of the Tx Information rate in the form: ddddd.ddd
