Filed: 1985-02-22
Abstract: PURPOSE:To keep the equitability of a call by providing a means to inform the ratio of the number of a subscriber that is specified in a denoted outgoing to a program and providing a circuiting means not to inform a subscriber's call by the ratio of the specification of an assigned outgoing. CONSTITUTION:An instruction for an outgoing specification by a maintenance engineer is transferred to an outgoing specification control device 2 from an operating board 1. The outgoing specification control device 2 transfers this information to a central processor unit 5 and after receiving an information about a subscriber's group for the outgoing specification time-rotated by a program, this is transferred to a call detection circuit 3 in which a time division processing of an outgoing information from a subscriber's circuit 4 is executed according to the stored position of a subscriber. Therefore, a call is not informed to the central processor unit 5 when the stored position of the subscriber coincides with the subscriber's group for the outgoing specification and the call is informed to the central processor unit 5 when they do not coincide. Thereby, the fixing of the subscriber's group that receives the outgoing specification is prevented and the equitability of service to the subscriber is maintained.

IPC: G06F15/16
Filed: 1989-02-14
Abstract: PURPOSE:To reduce overhead caused at distribution of jobs to processors by constituting a processor such that the processor receiving a contribution degree from another processor carries out the relevant job when its own contribution is the highest degree. CONSTITUTION:When a job is applied, the specifications of the job are broadcast to all processors 1a-1c connected to each other via a message exchange means. Receiving the job specifications, each of processors 1a-1c broadcasts its contribution degree set against the job specifications to the processors 1a-1c connected to the message exchange devices 2a-2c. Each processor receives the contribution degree and carried out the due job when its own contribution is the highest degree. As a result, the exchange of messages are through in a single reciprocating action up to the distribution of processors and therefore the overhead is reduced.
