Data Connect Enterprise, Inc. Powered Modem-Sharing Device Model 3018

Description
The Model 3018/V24 Modem Sharing Device (MSD) enables users to expand their polled or contention networks without acquiring additional data lines or modems. DSDs act as combined modem and port sharing devices. With one of these bi-directional units, up to eight sync or async terminal devices can share one modem in a polled or contention environment. Data arriving at the master port is continually broadcast to all sub-channels. The first sub-channel to activate RTS is automatically given control of the master port. When RTS is deactivated, the MSD enables any other sub-channel to take control of the master port. Sub-channels contend for the main channel by activating RTS, DCD, or by detecting data transitions.
