Description of Arguments
Command or Query (Query only in IP-ACM).
Tx Data rate, in kbps, between 18 kbps and 25 Mbps Resolution=1 bps
Example: TDR=02047.999 (selects 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 (Command or Query in IP-ACM).
Allows remote access to the Tx symbol rate, in the form ddddd.ddd
Note: Symbol Rate ranges in IP-ACM = 37 ksym/sec to 4100 ksym/sec
Command or Query.
Frequency ranges:
50 MHz to 180 MHz, and
950 MHz to 2250 MHz (L-Band – FAST option)
Resolution=100Hz.
Note: The CDM-625A supports 70,140 MHz bands and L-Band.
Example: TFQ=0950.9872
Command or Query.
