  • Methods and apparatus for improved communications networks
    Patent number: 8320409
    Abstract: Erroneous data due to faults are prevented from propagating through a distributed network node having diversely routed communications links by using a fault masking technique that eliminates the 60 ms of error propagation time associated with SONET networks. The fault masking technique can also prevent random bit errors from propagating through the distributed network node. A frame alignment technique used in the network node is scalable for very wide words (e.g., 128 bits) for use with high speed optical communications protocols, such as OC-192.
    Type: Grant
    Filed: July 31, 2003
    Date of Patent: November 27, 2012
    Assignee: Tellabs Operations, Inc.
