This attribute specifies the emission priority of frames sent to this
FrAtm interface from its network interworking functions. Frames in
a higher priority queue are sent before frames in a lower priority
queue.
The value of this attribute is interpreted according to the value of
the provisionable attribute numberOfEmissionQs under the parent
FrAtm component. If the numberOfEmissionQs attribute is set to 2,
niwfEmissionPriorityToIf value of 0 maps to emission priority
queue 0 representing a lower priority queue, and
niwfEmissionPriorityToIf values of 1, 2 or 3 map to emission
priority queue 1 representing the highest priority queue. If the
numberOfEmissionQs is set to 4, the emissionPrioToIf values
directly assign to the emission priority queues.
A value of deriveFromTp specifies that the emission priority is
extracted from the Mod Frs AtmNet Tpm/n component using the
niwfTransferPriority attribute.
The niwfEmissionPriorityToIf can also be overridden on a per
connection basis by setting the emissionPriorityToIf atribute in the
FrAtm Dlci Niwf Qos component.
