Description
Indicates the center frequency (in MHz) for which the integrated
upconverter has been configured.
Indicates the power level (in dBmV) of the signal that the
integrated upconverter is receiving from the cable interface line
card in the Cisco uBR7100 series router.
Indicates the power level (in dBmV) of the RF output signal that
the integrated upconverter is transmitting on the DS0 RF port.
