ABSTRACT:
In one embodiment, the invention is an apparatus for testing differential delay correction of network elements using virtual concatenation. The apparatus includes a first PRBS (pseudo-random bit stream) generator dedicated to a first tributary. The apparatus also includes an interface between the first PRBS generator and a tester. The apparatus further includes an interface between the first PRBS generator and a device under test. The apparatus may further include a second PRBS dedicated to a second tributary. The apparatus may also include a control logic block to control the first PRBS generator and the second PRBS generator, and coupled to the first PRBS generator and the second PRBS generator.
