The following is sample output for the downstream connection for slot 3 on port 0 on Cisco CMTS router
from the show controllers cable downstream command:
CMTS01# show controllers cable 3/0 downstream
Cable 3/0 Downstream is up
Frequency not set, Channel Width 6 MHz, 64-QAM, Symbol Rate 5.056941 Msps
FEC ITU-T J.83 Annex A, R/S Interleave I=12, J=17

For cable interfaces that include an integrated upconverter, the show controllers cable command
includes the frequency and power settings for the integrated upconverter. The following example shows
typical output for the show controllers cable command that includes the information for the integrated
upconverter:

describes the fields displayed by the show controllers cable downstream command.
Description
Slot number/port number indicating the location of the Cisco cable
interface line card.
Indicates that the RF downstream interface is enabled.
Transmission frequency of the RF downstream. (This information
may not match the current transmission frequency, which is
external on CMTS platforms that use an external upconverter.)
Indicates the width of the RF downstream channel.
Indicates the modulation scheme.
Indicates the transmission rate (in number of symbols per second).
Indicates the Motion Picture Experts Group (MPEG) framing
standard.
Indicates Reed Solomon framing based on ITU S.83-B.
