cdxCmtsCmChOverState The status of the specified channel override operation.
The enumerations are:
• messageSent(1): the CMTS has sent a RNG-RSP
message with channel override to the MTA.
• commandNotActive(2): the command is not in active
mode due to this entry's row status is not in active yet.
• noOpNeed(3): The downstream frequency and the
upstream channel Id in this entry are the same as original
ones when this entry's row status is set to active, so
CMTS does not need to do any operation.
• modemNotFound(4): The modem is not found in the
CMTS at the time when the command becomes active.
• waitToSendMessage(5): specified the operation is active
and CMTS is waiting to send a RNG-RSP message with
channel override to the MTA.
• timeOut(6): specified the operation is timed out. That is,
the CMTS cannot send a RNG-RSP message with
channel override to the MTA within the time specified in
the object of cdxCmtsCmChOverTimeExpiration. The
possible reason is that the MTA does not repeat the initial
ranging.
The possible state change diagram is as below:
[commandNotActive ->] waitToSendMessage ->
messageSent or timeOut.
[commandNotActive ->] noOpNeeded or modemNotFound.
cdxCmtsCmChOverRowStatus The status of this table entry.
This value for cdxCmtsCmChOverMacAddress must be valid
Mac address currently in the CMTS in order for the row
status to be set to active successfully.
Once the row status becomes active and state becomes
waitToSendMessage, the entry cannot not be changed except
to delete the entry by setting the row status to destroy(6) and
since the operation cannot be stopped, the destroy(6) will just
cause the SNMP agent to hide the entry from application and
the SNMP agent will delete the entry right after the operation
is completed.
