Abstract:
1. In a digital communications network, a method comprising: monitoring a plurality of links to determine state changes of the links between a first inverse multiplexing for asynchronous (IMA) group and a second IMA group; enforcing an inverse multiplexing for asynchronous transfer mode identification (IMA-ID) check when an insufficient links state is reached, such that a link for which a near end IMA-ID matches a far end IMA-ID is maintained and a link for which a near end IMA-ID does not match a far end IMA-ID is disabled; relaxing the IMA-ID check when all the links are in an error state; and re-enforcing an IMA-ID check when at least one link of the plurality of links recovers from an error state to resynchronize the first IMA group and the second IMA group on a per group basis.
