PURPOSE:To realize an economical and high-efficiency link frame connection system where two connection points of the same row or line of an arbitrary idle grid, which becomes the folded grid of the link frame, are connected simultaneously. CONSTITUTION:Many link frames LLF and trunk link frames TLF represented by LLF0 and and TLF0 are connected mutually by junctor J as generally known. Switches TS0, TS1, QS0 and QS1 constituting trunk link frame TLF0 are so constituted that two connection points of the same row or line can be connected simultaneously. As the result, for example, connection between trunks T0 and T1 is achieved by connecting two connection points A and C or B and D of switch QS0 simultaneously, and connection between trunks T0 and T3 is achieved by connecting two connection points A and B of switch TS0 simultaneously. |
