Table 3-44 describes the fields related to the integrated upconverter that are displayed by the show
controllers cable downstream command.
The following is sample output from the show controllers cable upstream command for a Cisco CMTS
router with a cable interface card located in slot 4, port 0:
CMTS01# show controllers cable 4/0 upstream 2

Table 3-44 show controllers cable downstream upconverter Field Descriptions
Field Description
Downstream Frequency Indicates the center frequency (in MHz) for which the integrated
upconverter has been configured.
IF Power 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.
RF Power Indicates the power level (in dBmV) of the RF output signal that
the integrated upconverter is transmitting on the DS0 RF port.
