| Description | This attribute specifies the nominal interval in
microseconds between successive unicast request opportunities
on an upstream Service Flow.
This attribute applies only to upstream Service Flows
with SchedulingType of value 'nonRealTimePollingService',
'realTimePollingService', and 'unsolictedGrantServiceWithAD'.
The parameter is mandatory
for 'realTimePollingService'. If the parameter
is omitted with 'nonRealTimePollingService',
the CMTS uses an implementation-dependent value. If
the parameter is omitted with 'unsolictedGrantServiceWithAD(5)'
the CMTS uses the value of the Nominal
Grant Interval parameter. In all cases, the CMTS reports
the value it is using when the parameter is applicable.
The CM reports the signaled parameter value
if it was signaled. Otherwise, it returns 0.
If the referenced parameter is not applicable to the
direction or scheduling type of the corresponding DOCSIS
QOS Parameter Set, both CMTS and CM report this
attribute's value as 0. |
