A concrete circuit configuration is proposed of a multiplex transmitter for loading a standard ATM cell with multiplexed micro-frames which are each shorter than the standard ATM cell.

The distributing information accords with the service condition of each connection or micro-frame. An extracting circuit 506 selects buffers in accordance with predetermined buffer selection logic.

Why it's free to use
- Filed December 24, 1996 and granted August 7, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 24, 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.
