Title: Star-connected lan equipment
Inventor: TSUBAKI MASAMITSU
Filed: 1987-12-07
Abstract: PURPOSE:To reduce possibility of occurrence of collisions so as to improve the throughput of a system by causing signals from low-order repeater equipment or terminal equipment to be transmitted to low-order repeater equipment or terminal equipment also and, at the same time, transmission of signals from high-order repeater equipment to low-order repeater equipment or terminal equipment to be inhibited. CONSTITUTION:Signals DI1-DOk from low-order repeater equipment or terminal equipment are inputted to a signal selecting collision detecting section 13 after they are amplified and level-converted by means of a receiver 14 and simultaneously compared with signals UDI from high-order repeater equipment. When a collision is detected a collision signal is generated by a collision signal generating section 15 and sent to the high-order repeater equipment as a signal UDO through a driver 11. When no collision is detected, the timing is recovered at a waveform shaping section 12 and sent to the high-order repeater equipment through the driver 11. Therefore, the probability of occurring collisions is reduced and the throughput of this system is improved, since the time until a carrier is detected is sharply reduced.
