fr Circuit Throughput
1.3.6.1.2.1.10.32.2.1.14
Throughput is the average number of 'Frame Relay Information Field' bits transferred per second across a user network interface in one direction, measured over the measurement interval. If the configured committed burst rate and throughput are both non-zero, the measurement interval, T, is T=frCircuitCommittedBurst/frCircuitThroughput. If the configured committed burst rate and throughput are both zero, the measurement interval, T, is T=frCircuitExcessBurst/ifSpeed.
