Table: Serial Interface Signals shows the serial interface of the CPRI core.
The lossoflight signal is intended to be driven by the Loss of Light output of an attached optical module; it signals that the optical receiver is not receiving illumination from the peer. If an optical module is not in use, this signal should be tied to 0.
The txinhibit signal is wired to the input of the transceiver but should also be connected to inhibit the optical transmitter in a connected module. If an optical module is not in use, this signal can be left as is.
