Executive Summary

Otis Elevator Company, a wholly-owned subsidiary of United Technologies Corporation, is the world's largest manufacturer, installer, and servicer of elevators, escalators, moving walkways and other horizontal transportation systems. When Otis began to migrate from an expansive SNA network to a consolidated IP environment, they began to replace multiple terminal emulation products, including IBM Personal Communications/3270, PACKET PC and Attachmate EXTRA!, with Zephyr's IP-based PASSPORT terminal emulation software. After working collaboratively with consultants and Otis, the transition from the S/390 mainframe to the UNIX host system was successfully accomplished in less than a month.
