The invention provides for an E-Mux and a method for encapsulating/segmenting ATM cells into/from an Ethernet frame at the boundary between an ATM and an Ethernet network. An Ethernet end-station on the E-Mux is addressed using multiple MAC level identifiers, which are dynamically assigned according to the ATM virtual circuits which terminate on that end station and have only , transitory significance on the Ethernet. A unique ATM OUI identifies the frames carrying ATM-traffic.

Why it's free to use
- Filed March 11, 1998 and granted February 4, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 11, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 11, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
