The Comms Server Pro for Windows* NT is the gateway between the client workstations and
one or more host computers. It uses intelligent communication boards, or peripherals to
handle low-level communication details for the required protocols. It can also act as a ‘host’
for other gateways or control units if they are attached via a synchronous serial link (a
downline). It supports a large number of workstations (depending on the upline speed), and
several management connections. Each CSPNT can have a backup that can take over on
command or automatically in case of failure. CSPNT is part of the Global Connect solution.
