Enabling High-Performance DS1/E1 Pseudowire over Ethernet with 1588v2 Differential Timing

The DS1s and E1s used for mobile backhaul have stringent performance requirements. They are similar to other carrier infrastructure applications in their requirement for high reliability and bit-error performance. These circuits are more demanding than many infrastructure circuits, however in their latency, jitter and wander requirements. While the performance requirements for DS1/E1 mobile backhaul are not new, the prospect of putting these mission critical services over new packet infrastructure has made this a hot topic for discussion.
