depending on the systems configuration
Standard
15-pin Ethernet transceiver
cables
and
IEEE
802.3 attachment
unit interface
AUI
cables
can be
used
An
18-inch
transition
cable
is provided
for each Ethernet port This cable provides
flexibility
for alternate
connection
configurations
Three
configurations are possible
The
transition
cable
can be used by itself to connect the router
directly
to the
media
attachment
unit
MAU
or transceiver
See
Figure

The
transition
cable
can be used as flexible
extension of
the
