Abstract
A node for communicating with a plurality of other nodes in a computer, the node including logic circuitry for transmitting and receiving data at first and second logic levels. A default generator is connected to an arbiter and responds to a lack of request activity and the absence of a multi-cycle data transfer being performed on the bus and causes the bus to be driven to one of the first and second logic levels.
