Description of Arguments
Command or Query. (DROP/D&I++/QDI parameter)
Sets or returns Drop Type in the form x, where:
0=T1-D4
1=T1-ESF
2=E1-CCS
3=E1-CAS
Command or Query. (DROP parameter)
(Note different format between command and query.)
Sets or returns Tx Drop timeslot – Command format is in the form xxy, where:
xx=Channel 01 through 24
y=timeslot: 0-9, A=10, B=11, C=12, D=13,...V=31
Command or Query. (G.703 parameter)
Sets or returns Tx Ternary Code in the form x, where:
0=AMI
1=B8ZS
2=B6ZS
3=HDB3
EXAMPLE: <0/ TTC=1 (selects B8ZS)
Command or Query. (IDR parameter)
Sets or returns Tx Backward Alarm Enable in the form xxxx, where:
0=Disable
1=Enable Internal (S/W)
2=Enable External (H/W)
EXAMPLE: <0/TBA=0120
Command or Query. (IDR parameter)
Sets or returns IDR ESC Type in the form x, where:
0=64k data channel
1=2 Audio channels
Command or Query.
Sets or returns Tx LO frequency information in the form xxxxxs, where:
xxxxx=LO frequency, in MHz, from 3000 thru 65000, or 00000 (OFF)
s=sign for the MIX (+ or –)
NOTE: Terminal Frequency=LO ± TFQ
EXAMPLE: <0/TLO=12000+ (BUC LO is 12GHz, low-side mix)
Query only.
Returns terminal (aka satellite) Tx Frequency, which is the frequency transmitted to the satellite, the form xxxxx.xxxx.
Resolution=100 Hz
NOTE: Returns 00000.0000 if LO is zero
EXAMPLE: <0/TTF? >0/TTF=11650.2249
Query only.
Allows remote access to the Aggregate Tx Information Rate in the form ddddd.ddd
