System Overview
special software package bundled with the CommPlete 4000, RAS Express can also be interfaced to
standard Radius authentication functionality (which resides on a separate PC).
RADIUS authentication software (Remote Authentication Dial-In User Service) handles authentication
and profile information about network users and secures against unauthorized server access. Built-in
R log protocol support permits remote log-in to all hosts on the network. RAS Express can facilitate
remote software upgrades via standard TFTP protocol.
The CommPlete 4000’s workstation re-director programs (WINMCSI and MCSIWSN) control modem
port assignments on the network.
