downstream direction. In such a case, using a loopback tool will always yield the same results since the measurement
will be affected by the lowest throughput, and test results will not show that one direction has higher performance than
the other. The same scenario will occur if a network misconfiguration is present in only one direction of the service.
Depending on the error, the problem will not be identified with round-trip measurements only. This can results in
customer complaints and additional truck rolls. With the dual test set approach, both directions are independently
analyzed at the same time and pass/fail results are provided per direction, yielding the highest level of confidence in
service testing.
Currently, this scenario requires an operator at each but we will soon release new software that allows the local test to
retrieve remotes results and display them on the on the local unit. This will ensure that the entire test routine can be
completed by a single person in control of a single unit, providing shorter test time and reduced manpower. Also,
because the two units will not be synchronized exactly when the test starts, there will be a level of inaccuracy in the
latency measurements.
