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 according to the communication environment of a connection network; and
a programmable logic device (PLD) coupled to sense a change in a connection state of the connector through a prescribed control line and to transfer the sensed information to the CPU.

Abstract
An apparatus and method of automatic router configuration is disclosed when a cable of the router in operation is replaced or a protocol configuration is changed, a PLD automatically senses the change and initializes parts of the system to normalize communication environments without turning off the power. A TVS circuit is provided to absorb and prevent an electrical shock so that cable replacement is made possible in the power-on state.
