ABSTRACT:
A SONET network element receives incoming SONET signals with a receive line interface (2) which stores the incoming data in an elastic store at the recovered line rate while a local interface reads the stored data at the local network element rate, which may vary slightly from the recovered line rate, and which adjusts the received pointers according to the difference between the line and local rates or phase, allowing the payload data to "float" with respect to the boundaries of frames containing both payload data and overhead with pointers; an elastic store monitor performs the comparison between the receive payload rate and the local clock by comparing write addresses at the recovered line rate and read addresses at the local network element rate by a subtraction process which causes pointer adjustments to be made in response to the subtracted difference exceeding selected memory limits. A process for carrying out VT/TU and/or STS/STM pointer interpretation and generation is shown.
