  • Digital loop diagnostic port test before insertion
    Patent number: 7496042
    Abstract: Methods and associated hub arrangements are described for use in diagnosis and recovery in high performance digital loops such as, for example, those seen in Fibre Channel systems. In one system having a hub configured for interconnection of a plurality of stations as part of a digital system such that digital data flows between the stations based on operational status of the system, an arrangement forms part of the hub which arrangement is connectable at points within the hub and between at least two different pairs of the stations for monitoring certain characteristics of the data in a way which provides for non-invasive identification of one or more conditions related to the operational status of the system.
    Type: Grant
    Filed: July 7, 2004
    Date of Patent: February 24, 2009
    Assignee: Emulex Design & Manufacturing Corporation
