Patent number: 5123013Abstract: A cell synchronizing apparatus and method for synchronizing the transmission and reception of a data train between switching systems. The data train is sectioned into a plurality of packeted data cells and synchronization cells of equal fixed length. A synchronization pattern is included in each synchronization cell. A time position of the synchronization pattern is detected and sequentially stored in a memory. Synchronization is determined from the relative positional relationship among time positions of equal value stored in the memory.Type: GrantFiled: September 12, 1990Date of Patent: June 16, 1992Assignee: Kabushiki Kaisha ToshibaInventor: Kouji Hirayama
