Description of Arguments
Command or Query.
Invert Transmit Data Clock in the form x, where:
0=Normal
1=Inverted
Command or Query.
TX Clock Source in the form x, where:
0=Internal
1=TX Terrestrial
2=Loop-Timed
3=Ext loop (G.703 interface only)
Example: TCK=0 (Internal)
Command or Query.
TX Code Rate in the form x, where:
0=Rate 5/16 (Turbo only)
1=Rate21/44 (Turbo only)
