Title: Two-wire type time division transmission system
Inventor: YAMAGUCHI MASARU
IPC: H04Q11/04
Filed: 1984-12-28
Abstract: PURPOSE:To reduce a crosstalk volume to other systems less than ever before by shifting the send-out timing of a leading bit in a frame from every terminal board with each other on a transmission from the terminal board of an intra- office circuit. CONSTITUTION:The send-out timing of the leading bit within a frame of a burst signal which is sent out by every terminal board of the intra-office circuit OCU2-1 through 2-m can be shifted with each other by delaying and distributing a bit clock signal in order by delay circuits 3-1 through 3-(m-1). In a former system, there is such a trouble that a disturbing crosstalk to other systems arises because the system has no delay circuits such as 3-1 through 3-(m-1) and ever leading bit of code '1' is sent out in a same timing from every OCU. But as stated above, the trouble is dissolved by shifting the timing of the leading bit with each other.
