Description: This attribute indicates the total time duration, in seconds since registration, the CM identified by docsIf3CmtsCmRegStatusId has been in Energy Management 1x1 mode, as controlled by the DBC-REQ Energy Management 1x1 Mode Indicator TLV.

What is docsIf31CmtsCmEmStatsEm1x1ModeTotalDuration?

Reports, in seconds since registration, the total time this cable modem has spent in Energy Management 1x1 mode (a DOCSIS 3.1 power-saving mode where the CMTS temporarily reduces the modem to one downstream/one upstream channel), as controlled by the Energy Management 1x1 Mode Indicator TLV in DBC-REQ messages. Admins can use this to verify that power-saving features are actually engaging for a given modem as expected, or to audit how much time modems spend in reduced-service power-saving states.

Examples
