SYNTAX Counter64
UNITS "Bytes"
MAX-ACCESS read-only

DESCRIPTION
"At the CMTS, the total number of DOCSIS data bytes
transported by this downstream channel. The number
of data bytes is defined as the total number of bytes
transported in DOCSIS payloads minus the number of
stuff bytes transported in DOCSIS payloads.
This is the 64-bit version of
docsIfCmtsDownChnlCtrUsedBytes and will not be accessible
to SNMPv1 managers.
Discontinuities in the value of this counter can occur
at reinitialization of the managed system, and at other
times as indicated by the value of
ifCounterDiscontinuityTime for the associated ifIndex."
