Description of Arguments
Command or Query. (G.703 parameter)
Rx Ternary Code in the form x, where:
0=AMI
1=B8ZS
2=B6ZS
3=HDB3
Example: RTC=1 (selects B8ZS)
Command or Query. (IDR parameter)
Enable Receive backward alarm enable in the form xxxx, where:
0=Disable
1=External trigger Enable
Example: RBA=0101
Command or Query. (IDR parameter)
Sets or queries IDR ESC Type in the form x, where:
0=64k data channel
1=2 Audio channels
Command or Query. (D&I/D&I++ only)
(Note different format between command and query.)
Insert Timeslot 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 only.
Forces the software to recenter the receive Plesiochronous/Doppler buffer.
Note: This command takes no arguments.
Example: RCB=
Command or Query.
LNB Rx LO frequency information in the form xxxxxs, where:
xxxxx is the LO frequency: 03000 through 65000 MHz, or 00000=Off
s is the sign for the MIX (Note: negative mix induces a spectral inversion)
Note: For additional information refer to Chapter 6 for LO, MIX, and Spectrum Settings.
Terminal Frequency = RX LO ± modem RFQ (see below)
