Madge Networks - AccessSwitch

Madge Networks, N.V. a leader and provider of Token Ring products, acquired the Teleos AccessSwitch (ISDN access switch) product family in 1996. By adding Teleos AccessSwitch product line to its Token Ring and ATM LAN switching portfolio, Madge Networks was able to provide an end-to-end solution for switched networks.

This solution was critical to the success of large business and government organizations that needed to integrate the delivery of data, voice and video to the desktop. However, with the acceleration of Ethernet technologies and the lessening focus on ATM to the desktop, the integrated platform Madge envisioned became less compelling over time. Eventually, Madge spun off the Teleos AccessSwitch products. Today, TKO focuses on installing, maintaining and managing these systems in enterprise networks.
