It supports pointer processing at STS-1 granularity for STS-192 and scalable concatenation levels STS-3c to STS-192c for a seamless upgrade path to STS-768 and provides extensive performance, error and alarming functions.
Using a SONET analyzer, a BERT is then performed in all of the communications channels, i.e., all 12 STS-1 channels (or 4 STS-3c channels) are checked one after another for bit errors in an OC-12 ring.
The generator in the test set provides a pseudo-random bit sequence (PRBS) for use as a test signal that is then inserted as a bulk signal into an STS-1 or STS-3c frame.
