Description of Arguments
Command or Query.
Tx Data rate, in kbps, between 18 kbps and 25 Mbps Resolution=1
bps
Example: TDR=02047.999 (which is 2047.999 kbps)
Additional auxiliary G.703 sub-rates are available, selected using:
00512.AUX
01024.AUX
02048.AUX
The connectors used for the Aux rates are IDI/DDO.
These Aux rates are not available with Drop & Insert or IDR.
Read-only if Framing Mode is Quad Drop & Insert (TFM=8). Data
rate is set by assigning the number of channels on each port.
Read only if Modulation Type is a 'Reserved' type
Query only.
This command allows remote access to the Tx symbol rate.
Format is ddddd.ddd
Command or Query.
Invert Transmit Data
0=Normal
1=Inverted
Exception: in 600/L emulation mode, instruction is ITD.
Example: TDI = 1 (selects TX Data Invert)
Command or Query.
Tx RS encoding
0=Normal (based on the Open Network framing selected)
1=IESS-310 mode, valid with QDI, unframed, IBS, D&I, IDR.
2=EF Data legacy standard (225,205) – unframed, QDI only
3=IBS (126,112) – unframed only
Example: TRS=0
(This is a 'don't care' if no RS is selected under FEC Type)
Available all framing modes, except EDMAC.
