Abstract

A switch with tandem ports and an outlet assembly permit individual segments of cable to be used with multiple data link protocol standards. The multiple data link protocols can be used either one at a time, with each group of wires in the cable carrying the same data link protocol in different communication sessions, or can be used in tandem, with each group of wires in the cable simultaneously carrying a different data link protocol.
