Open the CIPO recordAbstract From the Canadian patent
An assembly/disassembly system is comprised of a cell assembly and a cell disassembly, each assembly having one buffer memory with its memory area logically divided into a plurality of data areas (banks). The cell assembly receives TDM data to assemble ATM cells by storing the TDM data into the respective banks according to the virtual channels. When one of said banks stores the TDM data in the payload length of an ATM cell, an new bank (unused bank) is specified to store the TDM data successively.

Why it's free to use
- Filed January 28, 1994 and granted September 23, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 28, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 28, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
