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:
