This attribute specifies the default transfer priority for all outgoing
calls using this particular DNA. It can be overridden by the
transferPriority provisioned in the Dlci DirectCall sub-component.
The transfer priority is a preference configured for an application
according to its delay-sensitivity requirement. Frames with higher
transfer priority are served by the network before the frames with
lower priority. The transfer priority standard is defined to have 16
levels from 0 to 15.
Each transfer priority n, where n indicates the transfer priority
index, contains a default setting for routing class of service
(multimedia, delay or throughput) and frame relay egress queue
(depending on the number of supported egress queues on the remote
end interface) specified by the routingClassOfService and
emissionPriority attributes provisioned in the Mod Frs DprsNet
Tpm/n component. The default mapping can be altered by a user if
required.
The default defaultTransferPriority is 0.
