Abstract

See full text

An apparatus and method determine byte gain and loss adjustments that compensate for frequency differences between ingress and egress data rate signals in a SONET/SDH NE. The count of ingress data rate signal pulses at the time that data is requested by a switch fabric is compared to the count of egress data rate signal pulses at the time the requested data is passed through the switch fabric. If a delta phase equal to the difference in counts less a reference phase, is continuously greater than a positive value threshold for at least a time threshold period, then a byte gain adjustment is determined. On the other hand, if the delta phase is continuously less than a negative value threshold for at least the time threshold period, then a byte loss adjustment is determined.
