### Description

```asn1
docsIfCmtsDownChnlCtrUsedBytes OBJECT-TYPE
SYNTAX Counter32
UNITS "Bytes"
MAX-ACCESS read-only
STATUS current
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 32-bit version of
docsIfCmtsDownChnlCtrExtUsedBytes, included to provide
back compatibility with 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."
```

**Classification**: MIB object for network management
