ABSTRACT:
A server system constructed by a network using a known PBX in such a manner that information processing terminal equipment and server devices are held in normally-used extensions of the PBX together with other terminals such as telephones, facsimiles, etc. Logical channel numbers of packet links between the PBX and the information processing terminal equipment are assigned to electrically-connected server devices in association with each other and sent to users. The users sends server use data to corresponding destinations by data packets to which the logical channel numbers are applied. The PBX performs a packet exchange process such that the logical channel numbers are respectively associated with physical addresses of the server devices. If the PBX regards the users as improper users, then it does not inform the users of the logical channel numbers. When a logical channel number of a server device used at a user desire is recognized, the user can utilize the PBX server system even if a proper user does not know a physical address of the server device.
