Simplex provides a one-way ring connection from the FCI to the modem, to the
second modem, etc., and back from the last modem to the FCI.
•
Duplex provides a two-way connection, and is normally the best
communication design.
•
Duplex allows additional modems to be added down-stream on-line.
•
A cable break or loss of a modem will only affect I/O clusters down-stream of
the failure.
