Abstract:
1. An apparatus for automatic router configuration, comprising: a connector configured to provide a connection port to a data circuit terminating equipment (DCE); a multi-protocol transceiver coupled to the connector and configured to transmit and receive a plurality of protocol signals through the connector; a CPU having a serial communication control function coupled to the multi-protocol transceiver to process data received from or for transmission to a communication network according to a communication environment; a programmable logic device (PLD) coupled to sense a change in a connection state of the connector and to transfer information regarding the sensed change to the CPU; and an interrupt request (IRQ) signal line, an acknowledgment (ACK) signal line, a chip select (CS) signal line, a protocol mode line, and a cable state sensing line, wherein the IRQ signal line, the ACK signal line, and the CS signal line are coupled between the PLD and the CPU, and the protocol mode line and the cable state sensing line are coupled between the PLD and the connector, and wherein the IRQ signal line and the ACK signal line each separately comprise a control line to carry information between the CPU and the PLD relating to a change in the connection state of the connector, wherein the state is one of connection and disconnection.
