Patent ID: 7302186

Claim:
Circuitry for monitoring an optoelectronic transceiver, comprising: a host adapter, configured to couple an optoelectronic transceiver to a host device, the host adapter being a separate and distinct device to the optoelectronic transceiver and including: a transceiver interface for receiving from the optoelectronic transceiver digital values corresponding to operating conditions of the optoelectronic transceiver; memory including one or more memory arrays for storing information related to the optoelectronic transceiver, including the digital values received from the optoelectronic transceiver; comparison logic configured to compare the digital values with limit values to generate flag values, wherein the flag values are stored in predefined flag storage locations within the memory during operation of the optoelectronic transceiver; and a host interface configured to enable a host to read from host specified locations within the memory, including the predefined flag storage locations, in accordance with commands received from the host.
