    摘要: A multiplexing system for ISDN circuits. Multiplexers in the system include data terminals, voice interfaces having voice trunks, high speed digital circuits and ISDN circuits, together with a control channel interface which connects trunking circuits by controlling calls on the control channel. When an outgoing voice call originates, data information from data terminals voice is multiplexed with compressed information from a voice interface and transmitted to trunking circuits. When calls originate, the control channel controls calls and connects them with trunking circuits. When using ISDN circuits, after setting up a communication channel for the circuits, a CPU controls calls to multiplex ISDN circuits on the control channel. By this structure decreasing the multiplexing ratio due to voice multiplexing call control on ISDN circuits can be eliminated when linking multiplexers with communication channels having high speed digital circuits and ISDN circuits.

    摘要: A telephone exchange system useful for a dealing speech system or the like is disclosed, which can accommodate large numbers of lines (or trunks) and permit improvement of the reliability and call connection processing capacity. The system comprises exchange sub-systems A (EX-A) and B (EX-B) capable of independently executing an exchange operation and each accommodating a terminal. The terminal has a speech channel switch for connecting a speech channel including a handset to either exchange sub-system A (EX-A) or B (EX-B). When the process of connecting a call is brought about in the terminal, it selects one of the exchange sub-systems and controls the speech channel switch for connecting the call to the selected exchange sub-system.

    摘要: One of the hand wheel and the brake ratchet wheel is provided with a cover portion extending toward the other thereof and having a circular peripheral surface which covers the lining plate, and the other of the hand wheel and the brake ratchet wheel is provided with a circular opposite peripheral surface opposed to the circular peripheral surface, so that opposite peripheral surfaces of those circular peripheral surfaces can be arranged adjacently to each other or have a scaling member interposed therebetween. Therefore, even when dust and rainwater enter a wheel cover for a hand wheel, these dust and rainwater can be prevented from further entering a mechanical brake.
