A system ( 10 ) and method are provided for restoring the flow of a data stream in the event of a link ( 28 ) failure while avoiding delays due to down time. The system ( 10 ) for passing the data stream at a particular transmission rate includes a first unit ( 20, 22 ) at the first location coupled to one end of each of a plurality of links ( 28 ), at least two trained links ( 28 ) selected from the links ( 28 ) that are set to active status, a second unit ( 22, 20 ) at the second location coupled to the other end of each of the links ( 28 ), and at least one idle link ( 28 ), wherein the first unit ( 20, 22 ) and the second unit ( 22, 20 ) switch to use the idle link ( 28 ) to replace any one of the trained links ( 28 ) that has failed. |
