Description
Number of invalid bandwidth (BW) requests. (An example of an
invalid bandwidth request is a modem using a nonexistent service
identifier (SID) to request bandwidth.
Total number of minislots requested.
Total number of minislots granted.
Size of the minislot in bytes.
Number of Upstream Channel Descriptors (UCDs) sent for this
upstream.
Interval data encryption standard (DES) controller register dump.
(Cisco uBR-MC16U/X, Cisco uBR-MC28U/X only) Number of
packets that were dropped because they had a Service Flow ID
(SFID) of 0, which typically happens because the packets were
dropped due to rate-limiting on their original service flow.
Revision of the JIB circuitry, which is the custom processor
onboard the BPE cards that handles the MAC-layer processing.
Status of the upconverter and whether it is currently outputting a
signal. If this field shows that the output is disabled, use the
no cable downstream rf-shutdown command to reenable it.
Configured frequency, in MHz, for the integrated upconverter (if
present).
Current RF power, in dBmV, as measured by the upconverter on the
cable interface line card. The upconverter's circuitry is accurate to
a few tenths of a dBmV, but might vary +/- 1 dBmV depending on
the transient noise that is occuring when the power is measured.
Description
Configures the downstream center frequency on the integrated upconverter.
Configures the desired RF output power on the integrated upconverter.
Creates spectrum groups, which contain one or more upstream frequencies.
Specifies that the upstream should be set to either a specific center frequency
or be set dynamically.
