Depending on FEC type, not all of these selections will be valid.
EXAMPLE: <0/RCR=1 (selects Rate 3/4)
Rx Data Rate
RDR=
9 bytes
Command or Query (Query only in ACM).
Sets or returns Rx Data Rate, the formxxxxx.xxx, where:
xxxxx.xxx=Value, in kbps, from 18 kbps to 25 Mbps
Resolution=1 bps
EXAMPLE: <0/RDR=02047.999.
NOTES:
1) Additional auxiliary G.703 sub-rates are available, selected using:
