<p>PURPOSE:To make the communication equipment small by devising a switch means so that a cell is transmitted to a new path being a changeover destination via a storage means and sending a final cell representing it that no cell comes from an old path being a changeover source afterward to a reception means. CONSTITUTION:In the case of changeover of a path at the side of a 1st transmission line 24 in communication to a path at the side of a 2nd transmission line 25, a control section 29 controls the setting of a path f-d in a transmission 20, and a control section 36 controls the setting of path h-j in a receiver 21. Then the control section 29 controls the changeover of the setting of a path a-c into a path a-e in the transmission 20, and as soon as a switching signal generating section 28 sends a final cell to a path (c) via a switch section 26, the generating section 28 sends a head cell to a path (d). When a switching signal detection section 37 of the receiver 21 detects the final cell, the control section 36 controls the setting of a path g-i to a path k-i.</p> |
