APPARATUS AND METHOD FOR AGGREGATION AND TRANSPORTATION FOR PLESIOSYNCHRONOUS FRAMING ORIENTED DATA FORMATS |
摘要 |
The invention provides an apparatus and method for transparently transporting four pleisiosynchronous OC-48 signals (105, 110, 115, 120) over a network (100). Multiple plesiosynchronous data streams are aggregated onto an independent clock source at an ingress circuit (145) through the use of 'stuffing' bits. The independent clock is selected such that the output data rate is greater than the composite input data rate of all the plesiosynchronous data streams. The signal is encapsulated with forward error correction at the transport interface, serialized, and modulated across the transport system (125). An egress circuit (140) at the receiving end recovers the modulated signal and extracts the data stream and the timing extraction resulting in a return of the original data frames with the same timing as the originals. In this manner, the timing is reproduced identical to the timing of the incident signal at the ingress path, ensuring the data is identical in content and timing. |
