Command or Query
Tx Modulation Type, where:
0 = Rate 1/2
1 = Rate 3/4
2 = Rate 7/8
3 = Rate 2/3 (8-PSK TCM or LDPC only)
4 = Rate 1/1 (Uncoded or No FEC)
5 = Rate 21/44 (Turbo Only)
6 = Rate 5/16 (Turbo Only)
7 = Rate 0.95 (Turbo Only)
Depending on FEC type, not all of these selections will be
valid.
Example: TCR=1 (which is Rate 3/4)
Command or Query.
Tx Data rate, in kbps, between 4.8 kbps and 20 Mbps
Resolution=1 bps.
Example: TDR=02047.999 (which is 2047.999 kbps)
For Hardware Version 2.0 or higher, additional auxiliary
G.703 sub-rates are available.
These are selected using:
00512.AUX
01024.AUX
02048.AUX
The connectors used for the Aux rates are IDI/DDO.
The Aux rates are not available with Drop & Insert or IDR.
Command or Query.
Tx RS encoding
0=Normal (based on the Open Network framing mode selected)
1=IESS-310 mode Available all framing modes, except EDMAC.
2=EF Data legacy standard (225,205) – unframed 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.
