1. A transceiver for coupling a terminal to a local area network across first and second data links, comprising:

  • a first pod for connection to the first data link and a second port for connection to the second data link to couple both the first and second ports to the local area network;

    a switch unit, having a first state providing for communication between the terminal and the first port for receiving and transmitting data signals on the local area network, and a second state providing for communication between the terminal and the second port for receiving and transmitting data signals on the local area network; and

    a monitoring circuit, coupled to the switch unit and the first and second ports which detects a current state of the switch unit, and conditions of the transceiver, including transmission of data signals through the transceiver, and the presence or not of data signals from the network on the first and second ports, and controls the switch unit in response to the current state of the switch unit and the detected conditions of the transceiver.
