PACX
From Wikipedia, the free encyclopedia
PACX (Private Automatic Computer eXchange) was a name given by Gandalf Technologies to their family of data switching products.[1][2]
The PACX was a centralized switch that allowed serial connections from end users to be connected to any one of a number of computers, typically mainframes. Users were equipped with small boxes with two thumbwheels on them, and by rolling the wheels to a given two-digit number they could select among the machines connected to the PACX. In typical setups, the PACX would be connected to computer terminals or modems.[3] The switch box would be queried on connection for the user's selection, and then a direct connection would be made between the user and that machine. The system was not unlike the telephone network, and the name PACX was deliberately chosen to suggest a computer-side analog of the PABX market.
