IPC: H04J3/06
Filed: 1990-06-02
Abstract: PURPOSE:To prevent data missing by eliminating a phase difference between data of plural channels sent via different paths from a same sender and minimizing the delay when part of the channel is interrupted or a new channel is added. CONSTITUTION:A most delay timing detection means 1 detects a timing of reception of each multi-frame of a most delayed channel among data from plural channels and outputs a 1st timing signal.
