Response to Query
Tx Data Rate TDR= 9 bytes
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
