bank
of nine
LEDs

is
located
on
each
FDDI
applique
to
indicate the
current
line
state
of each
of the
two
physical
connections
to the
applique
PHY-A
and
PHY-B
as
described
in
Table
B-5
When
the ring
is
operational
when
the
line
protocol
is
up
the
LEDs
will
oscillate
between
ILS
ALS
and
MLS
These
line
states
are defined in Table
B-5
The ILS
will
predominate
so
LED
will
glow most
brightly
LED
will
be
slightly
dimmer
And
LED
will
be
almost completely
dark The X3T9.5
FDDI
specification
explains
the
meaning
of these
line
states

detail
