Abstract
A receive SONET line interface includes an elastic store which receives and stores incoming signals from a pointer tracking circuit and retrieves stored signals for providing to a pointer generating circuit wherein, for both the pointer tracking and pointer generating circuits, separate state memories are provided for keeping track of the state of previous state pointer tracking and generating signals in time slots of repetitive frames of an incoming SONET signal.
