Abstract
In a distributed, multi-node system for communicating between a plurality of distributed terminals and one or more central computers, some of which specify command and control information to the nodes, intelligent means are provided in the nodes to enable the nodes to test their internal communication channels and the communication channels to their associated distributed terminals independently of the central computers, and to reconfigure themselves independently of the central computers, substituting spare channels for identified malfunctioning ones. Conditions detectable by or within the node may initiate such testing. This means comprises a script interpreter which causes the node to execute scripts previously provided to it. New scripts may be provided to the nodes from a central computer.
