Abstract:
1. An electronic apparatus comprising: a transmitter comprising a plurality of free slots configured to connect boards to a transmission path and a fixed slot connected to the free slots by the transmission path, the free slots associated with a plurality of channels; a host controller configured to manage quality of signals transmitted from and to the boards connected to the free slots and a dedicated slot; an electronic circuit board configured to be inserted into one of the free slots associated with the channels, the electronic circuit board comprising: a first transceiver configured to transmit and receive signals through the transmission path in accordance with a transceiver parameter, a transceiver controller configured to control a transceiver process at the first transceiver, a first parameter setting unit configured to set the transceiver parameter to the first transceiver, and a first controller configured to monitor the operating state of the first transceiver and to control the first parameter setting unit; and a switching process board configured to be connected to the dedicated slot, the switching process board comprising: a plurality of second transceivers configured to transmit and receive signals between electronic circuit boards configured to be connected to the free slots in accordance with the transceiver parameter, a switch unit configured to turn on or off the second transceivers, a second parameter setting unit configured to set the transceiver parameter to the second transceivers associated with the channels, and a second controller configured to monitor the operating state of each second transceiver and control the second parameter setting unit, wherein, while any one electronic circuit board remains inserted in one free slot in an initial state, the first controller is configured to monitor a receiving state of the first transceiver and control the first parameter setting unit, causing the first parameter setting unit to change the transceiver parameter of the first transceiver, and if the receiving state remains unchanged to a first state, the first controller is configured to inform the host controller that the receiving state remains unchanged to the first state; the host controller is configured to instruct the switching process board to designate a channel to change the first state, the receiving state of the electronic circuit board associated with the channel and informed of the instruction; and the second controller is configured to cause the second parameter setting unit to change the transceiver parameter of the second transceiver of the channel designated by the host controller.
