Each PC can have up to two SYSMAC LINK Units mounted. Each SYSMAC
LINK Unit will connect it to a SYSMAC LINK Network, i.e., if a PC has two
SYSMAC LINK Units mounted, it is part of two SYSMAC LINK Networks and
the overall system is considered a Multilevel SYSMAC LINK System. Operat-
ing levels, which are described later in this manual, are used to differentiate
between the two Networks to which one PC might belong.
The SSS/CVSS connection is not a required part of the System. It is shown
here because of its usefulness in monitoring and controlling not only the
operation of the SYSMAC LINK System itself, but the general operation of all
the PCs connected in the same Network(s) as the PC to which the SSS/
CVSS is connected.
The abbreviation SLK indicates a SYSMAC LINK Unit.
