Title: Reception transmission line selector for multiplex transmission system
Inventor: KONO SHINYA
IPC: H04L12/40
Filed: 1988-05-10
Abstract: PURPOSE:To always select a normal transmission line as a reception transmission line in a short time by recognizing the data arrival from each transmission line, discriminating the normality and abnormality of the reception data and selecting the transmission line of the data whose earlier arrival is recognized among the reception data subject to discrimination of its normality as a reception transmission line. CONSTITUTION:A data sent from a transmission circuit 3 is sent to an A system transmission line and a B system transmission line respectively via drivers 1A, 1B. A selection circuit 12 selects a transmission line of the system whose data arrival is recognized earlier by both diagnostic circuits 11A, 11B. A transmission line subject to discrimination of a fault by the normal/fault discrimination of a reception data by both the diagnostic circuits 11A, 11B is regarded to have a fault till the data subject to discrimination of normality by the relevant diagnostic circuit is received to inhibit the selection of the transmission line. Thus, the normal transmission line is selected as the reception transmission line in a short time at all times and the transmission fault due to a delay in the switching timing of the reception transmission line is prevented to build up the stable multiplex transmission system.
