ABSTRACT:
A local area network (10) includes a communications switch multi-port selector (12) which functions as the hub of the network. There are connected to the selector (12) various types of stations (14, 16) and terminals (18, 20, 22 and 24) which utilize a common communication format such as ASCII. The network further includes a computer (52) which uses a communication format that is incompatible with the stations and terminals connected to the port selector (12). Protocol converters (30, 32, 34 and 36) are connected between the port selector (12) and the computer (52) to provide translation between the communication formats of the computer (52) and the various stations (14, 16) and terminals (18, 20, 22, 24). A computer (54) is further provided which is connected to the port selector (12) and utilizes the communication format of the stations and terminals. The network (10) thus provides the capability for a substantial number of conventional stations and terminals to communicate with a preexisting computer system in a flexible and inexpensive manner despite the incompatibility of the communication formats.
