Abstract
A system provides more cost and bandwidth efficient utilization of a SONET network having both a Working path and a Protection path by using both communication paths to carry data. A system for communicating data over a Synchronous Optical Network/Synchronous Digital Hierarchy, the system comprises an Optical Line Termination unit operable to interface with a plurality of Synchronous Optical Network/Synchronous Digital Hierarchy communication paths, and communicate different data on each of the plurality of Synchronous Optical Network/Synchronous Digital Hierarchy communication paths.
Claims4
A system for communicating data over a Synchronous Optical Network/Synchronous Digital Hierarchy, the system comprising:
- an Optical Line Termination unit operable to:
- interface with a plurality of Synchronous Optical Network/Synchronous Digital Hierarchy communication paths,
- communicate a portion of data of a communication over the Synchronous Optical Network/Synchronous Digital Hierarchy on a first communication path of the plurality of Synchronous Optical Network/Synchronous Digital Hierarchy communication paths employing the entire bandwidth of the first communication path to communicate the data of the communication over the Synchronous Optical Network/Synchronous Digital Hierarchy;
- communicate a different portion of the data of the same communication over the Synchronous Optical Network/Synchronous Digital Hierarchy on a second communication path of the plurality of Synchronous Optical Network/Synchronous Digital Hierarchy communication paths employing the entire bandwidth of the second communication path to communicate the different data of the communication over the Synchronous Optical Network/Synchronous Digital Hierarchy;
- wherein the portion of the data of the communication over the Synchronous Optical Network/Synchronous Digital Hierarchy and the different portion of the data of the same communication over the Synchronous Optical Network/Synchronous Digital Hierarchy are communicated simultaneously;
- and
- communicate the portion of the data of the communication over the Synchronous Optical Network/Synchronous Digital Hierarchy and the different portion of the data of the same communication over the Synchronous Optical Network/Synchronous Digital Hierarchy on the first communication path employing the entire bandwidth of the first communication path when a break is detected in the second communication path, wherein when the first communication path is a working path the second communication path is a protection path and when the first communication path is a protection path the second communication path is a working path.
