Abstract: PCT No. PCT/KR93/00055 Sec. 371 Date Aug. 25, 1994 Sec. 102(e) Date Aug. 25, 1994 PCT Filed Jul. 2, 1993 PCT Pub. No. WO94/01962 PCT Pub. Date Jan. 20, 1994The Centralized Management System utilizing a Bus Interface Unit comprises a Computer (4z) installing an address Bus (4a), data Bus (4b), and control Bus (4c), a First-Level Station (4Q 1) communicating with the Computer (4z) as the First-Level Station (4Q 1) is connected to the buses (4a, 4b, 4c) of the Computer (4z), a plurality of second-level stations (4Q2, 4Q3, . . . , 4QM) communicating with the First-Level Station (4QI) as the second-level stations (4Q2, 4Q3, . . . , 4QM) are connected to the First-Level Station through a Multipoint Bus (4r). Therefore, the Centralized Management System is capable of communicating the Computer with the First-Level Station through a Dual Port RAM (Random Access Memory), intercommunicating a plurality of Second-Level Stations through a Multipoint Interface and Multipoint Bus, and controlling and managing several thousands of Terminals (for example, Public Telephones).
