Arguments for
Command or
Response to
Query
Command or Query.
Invert Receive Clock in the form x, where:
0=Normal
1=Inverted
Example: RCI=1 (selects Inverted RX Clock)
Command or Query.
Rx Clock Source, where:
0=Rx Satellite
1=Internal
2=Tx-Terrestrial
3= External Clock (only valid with the G.703 Option Card)
Note: Commands as well as queries are not allowed when either the GigaBit
Ethernet or NP card has been selected as the current interface type.
Example: RCK=2 (selects Tx-Terrestrial)
Command or Query.
Rx RS encoding in the form x, where:
0 = RS(225,205,10)
1 = RS(219,201,9)
2 = RS(208,192,8)
3 = RS(194,178,8)
4 = RS(126,112,7)
5 = RS(220,200,10)
Depending on Modem mode, overhead type, and data rate, not all selections will be
valid.
Example: RCW=0 (This is a 'don't care' if RS is Off under TRS)
Command or Query.
Rx Differential Decoding in the form x, where:
0=Off
1=On
Depending on FEC type or Modulation Type, not all selections will be valid.
Example: RDD=1 (selects Rx Differential Decoding On)
Command or Query.
Receive Data Fault, where:
0=None
1=DATA
2=AIS
Example: RDF=0 (selects Data Fault = None)
