MaintenanceWindowBegin/emtaMaintenanceWindowBegin
(1.3.6.1.4.1.4413.2.2.2.1.6.2.1.0 OCTET STRING)
This object identifies the start of an eMTA maintenance window. A
maintenance window is a period of time during which the ISP may perform
network maintenance operations and network outages or software resets
may occur. During a maintenance window, the eMTA will maintain the line
voltage of an MTA regardless of CM resets, MTA resets, or RF losses. If
any of these conditions occurs or persists outside of the scheduled
maintenance window then the line voltage will be dropped unless the
corresponding bit for the condition in question is set in the
emtaMaintenanceControlMask MIB. If this object has never been set, it
will have the value of midnight, January 1, 1970. Note that the time value
used here is the local time as known by the device, as opposed to UTC.
Also note that the value of this object will persist across a system reboot.
MaintenanceWindowDuration/emtaMaintenanceWindowDuration
(1.3.6.1.4.1.4413.2.2.2.1.6.2.2.0 Unsigned32)
This object identifies the duration, in seconds, of an eMTA maintenance
window. Setting the value of this object to the default value of zero
will cancel the maintenance window. Note that the value of this object
will persist across a system reboot.
MaintenanceControlMask/emtaMaintenanceControlMask
(1.3.6.1.4.1.4413.2.2.2.1.6.2.3.0 BITS)
This object identifies the bit mask to control the line voltage behavior
of the eMTA in various scenarios: maintenanceOnCmReset(0) - if this bit
is set to 1 it requires the line voltage be maintained in the case when
the CM has been reset, regardless of the reason (reset after downloading
a new firmware, or hard reboot, or SNMP induced CM reset), and regardless
of whether the MTA is in a valid maintenance window maintenanceOnRFLoss(1)
- if this bit is set to 1 it requires the line voltage be maintained in
the case when RF communication is lost, regardless of the reason, and
regardless of whether the MTA is in a valid maintenance window
maintenanceOnMtaReset(2) - if this bit is set to 1 it requires the line
voltage be maintained in the case when the eMTA is being reset, regardless
of the reason (e.g. SNMP induced eMTA reset, etc), and regardless of whether
the MTA is in a valid maintenance window maintenanceOnCMSLoss(3) - if
this bit is set to 1 it requires the line voltage be maintained in the
case when communication is lost with the CMS, regardless of the reason
(e.g. endpoint disconnected, etc), and regardless of whether the duration
of the communication loss has exceeded the value in the MIB
emtaMaintenanceQuarantineTimeout and/or
emtaMaintenanceDisconnectedTimeout.
