Object
If this attribute is set to a value of 'true' the CM must begin
looking for the presence of the Trigger Message Block in the PLC with
a Group ID matching the CM's 'docsPnmCmDsOfdmSymTrigGroupId'. The
TrigEnable is a one-shot enable and the attribute is internally
disabled when a PLC containing a Group ID matching the CM's
'docsPnmCmDsOfdmSymTrigGroupId' in a Trigger Message Block is received.
If this attribute is set to a value of 'false' the CM must stop
looking for the presence of the Trigger Message Block in the PLC with
a Group ID matching the CM's 'docsPnmCmDsOfdmSymTrigGroupId'. In this
case the value of the 'docsPnmCmDsOfdmSymMeasStatus' attribute will be
set to 'inactive'.
When read, the CM must return a value of 'true' if the CM is actively
looking for the presence of the Trigger Message Block in the PLC with
a Group ID matching the CM's 'docsPnmCmDsOfdmSymTrigGroupId'. Otherwise
the CM must return 'false'.
Interaction with other table rows:
- This object is subject to the rules specified by the
'docsPnmCmCtlStatus' object. Therefore this object returns
'inconsistentValue' if set to 'true' while the value of
'docsPnmCmCtlStatus' is any value other than 'ready'.
- This object returns 'inconsistentValue' if set to 'true' while the
CM is in DOCSIS Light Sleep (DLS) mode or the CM is in battery-backup mode.
- Default values for 'docsPnmCmDsOfdmSymCaptFileName',
'docsPnmCmDsOfdmSymTrigEnableTimeout', and 'docsPnmCmDsOfdmSymTrigGroupId'
objects are defined; thus, this object may be set to 'true' without
explicitly setting these values. Care should be taken to insure these values
are correct for the desired test case.
- Setting this attribute to a value of 'true' will change the value of the
'docsPnmCmDsOfdmSymMeasStatus' attribute to 'busy'.
