Bit error rate impact reduction

摘要

In an embodiment, a method includes receiving at a data interface a data stream having a plurality of logical communication channels. The data stream includes in succession a first data burst corresponding to one of the plurality of logical communication channels, a burst control word and a second data burst corresponding to the one or an other of the plurality of logical communication channels. The burst control word includes a first error check that protects the first data burst and the burst control word and a second error check that protects only the burst control word. The first error check and the second error check are examined. Only the one logical communication channel is errored out if the first error check is bad and the second error check is good; all open logical communication channels are errored out if the first error check is bad and the second error check is bad.

1. A method comprising:
receiving at a data interface a data stream having a plurality of logical communication channels, the data stream including in succession a first data burst corresponding to one of the plurality of logical communication channels, a burst control word and a second data burst corresponding to the one or an other of the plurality of logical communication channels, the burst control word including a first error check that protects the first data burst and the burst control word and a second error check that protects only the burst control word; examining the first error check and the second error check; erroring out only the one logical communication channel if the first error check is bad and the second error check is good; erroring out all open logical communication channels if the first error check is bad and the second error check is bad.
