<p>The cost of routing data in small systems, such as banking systems, is relatively high because of the failure to use up-to-date procedures, such as time sharing and modularity. Such costs are reduced by the present system by using a router logic module (20) to control interfaces for low order data terminals (24, 26, 28), high order host computer system (22) and a permanent store (52) through the use of a decision table incorporated into the router logic module. The router module (20) may be located on a substrate which permits the mounting thereof into one of the data terminals (24, 26, 28) so as to utilize the power supply of such data terminal rather than requiring a power supply of its own. Included in the low order data terminals is a printer module (30) which is permitted by the router logic module (20) to be utilized by several of the low order data terminals, the router logic module also permitting the low order data terminals (24, 26, 28) to communicate with each other without the intervention of the host computer system (22).</p> |
