In the ATM communication system the working preliminary both type electrolysis cell phase adjusting device

摘要

PURPOSE: To prevent disabic uninterruptible redundant changeover of transmission lines resulting from a deviated cell phase in both an active and a standby system when an idle cell is inserted in both the active and a standby system in an ATM cell format converter. ;CONSTITUTION: When an underflow of format conversion buffers 11A, 11B is detected by detection circuits 12A, 12B, its detection output is sent to other system. Idle cell insert control circuits 14A, 14B make idle cell command to idle cell insert circuits 13A, 13B of a concerned system to avoid a cell phase shift between both the systems when a detection output (idle cell insert command) is sent from the concerned system and other system.;COPYRIGHT: (C)1995,JPO
