btds L Co Emission Priority
This attribute indicates the urgency with which packets on the path are emitted by the trunks on the route. The originating end of the connection selects the emissionPriority. EmissionPriority of zero indicates the highest emission priority, while two indicates the lowest emission priority. Packets with a higher emissionPriority (or numerically less) are serviced and sent out before the packets of lower emissionPriority (or numerically higher).
