well, A MAU is a 8228 Multistation Access Unit. This unit provides eight workstation connectors and 2 MAU ports (also called Ring In/Ring Out ports).
A CAU is a 8230 Controlled Access Unit (Basically a MAU with
intelligence). A CAU supports up to four LAMs. The Ring In/Ring Outports of a CAU are copper, but can replaced with fiber connectors.
A LAM is a Lobe Attachment Module for the 8230. Each LAM supports 20 workstations.
