1. A method, comprising:

  • identifying a protocol associated with each of a plurality of communication signals by comparing respective data rates extracted therefrom to a stored data rate within a protocol table;

    determining, for each of the plurality of communication signals, a respective bit-error rate (BER);

    generating an alarm indicative of BER excursions beyond a protocol appropriate BER threshold level associated with the identified protocol;

    sampling each of the plurality of communication signals;

    converting the plurality of communication signals to respective electrical signals;

    amplifying each of the plurality of converted communication signals;

    locking to the plurality of communication signals to extract thereby respective clock rates; and

    converting serial high-speed data of the plurality of communication signals into lower speed parallel data prior to said identifying.
