Multiplex and demultiplex equipments for a digital synchronous link with variable flow and modulation rapidity

摘要

multiplexing and de multiplexing equipment is provided in the stations (1, 2) at the end of a bi-directional synchronous digital link (12, 21) in which a multiplexed signal has a variable flow at the request of one of the stations and the signal resulting from the tr ansmis online provides a variable modulation rate according to the flow rate.more specifically, in the context of an integrated services digital network (isdn), a multiplexing equipment and a de multiplexing equipment are designed to interface to a subscriber control routine or a terminal connected to the board so that each interface and be used in dynamic flow each direction of transmission.this allowed connecting any terminal, regardless of the flow is following the direction of transmission, to any one of the access terminals to the board, who are also common.
