A KVM switch is disclosed having on screen display (OSD) circuitry coupled to a user workstation for providing a user a convenient interface by which to operate the KVM switch. First switching circuitry coupled to a plurality of computers and coupled to the OSD circuitry allows a user to access any of the computers or the control functions of the KVM switch. Second switching circuitry coupled to switch electrical power to the computers and further coupled to the OSD circuitry allows a user of the KVM switch to selectively control electrical power to the computers.

Keyboard, mouse, video and power switching apparatus and method

An adaptive digital data unit (600) initiates and successfully completes a remote loop back test. The adaptive digital data unit (600) has a controller (610), a local transmitter (620), a local receiver (640) a timer (622) and a detector (634). When a remote adaptive digital data unit (600) transmits a first data sequence and a second data sequence, the local adaptive digital data unit (600) receives the second data sequence from the remote digital data unit and determines if the second data sequence matches one of two predetermined data sequences. If so, a test successful flag is generated.

Method for providing remote loop back testing in a digital data system

A communication system for coupling a plurality of data terminals to a telephone network has a time division multiplexed telephone network access bus, providing a plurality of time division slots containing data, coupled to the telephone network, and a digital terminal access bus coupled to the plurality of communication devices, each communication device being configurable to access any of the time division slots. A controller for configures each communication device to access a time division slot.
