    Historical PM Counters for BTI7000 Series DOL Modules

    PSM supports the retrieval and display of historical PMs from BTI7000 Series DOL modules. The actual PMs supported depend on the configuration and the software running on the network element, and may include some of the following:

    Table 1: Port PMs

    Name (abbreviated)

    Description

    Units

    LossRx

    The optical power loss measured on the port in the receive direction. For a line port, this represents the span loss. For a DCM port, this is the DCM loss. For a client port, this is the loss of the receive interconnection fiber.

    dBm

    LossTx

    The optical power loss measured on the port in the transmit direction. For a line port, this represents the far-end span loss. For a client port, this is the loss of the transmit interconnection fiber.

    dBm

    OPRAvg

    The average optical power received on the input.

    dBm

    OPRMax

    The maximum optical power received on the input.

    dBm

    OPRMin

    The minimum optical power received on the input.

    dBm

    OPRStdDev

    The standard deviation from the average optical power received on the input.

    dBm

    OPR

    The instantaneous optical power received on the input.

    dBm

    OPTAvg

    The average optical power transmitted at the output.

    dBm

    OPTMax

    The maximum optical power transmitted at the output.

    dBm

    OPTMin

    The minimum optical power transmitted at the output.

    dBm

    OPTStdDev

    The standard deviation from the average optical power transmitted on the output.

    dBm

    OPT

    The instantaneous optical power transmitted at the output.
