7 INTERFACE PANELS (ACCESSORY)
The
interface
panels
are
accessory
items
that
are
used
when
multiple
BTSs
and
multiple
HU’s
require
connection
or
when
RF
attenuation
is
needed
between
the
BTS
and
HU.
Two
types
of
panels
are
available:
the
Conditioning
Panel
and
the
Duplexing
Panel.
The
Conditioning
Panel,
shown
in
Figure 2-11,
provides
attenuation
of
the
forward
path
signal
to
the
level
required
for
input
to
the
HU.
The
Conditioning
Panel
also
provides
forward
and
reverse
path
combining
and
splitting
(as
needed)
to
enable
multi-BTS
to
single
HU,
multi-BTS
to
multi-HU,
or
single
BTS
to
multi-HU
configurations.
Figure 2-11. Conditioning Panel
The
Duplexing
Panel,
shown
in
Figure 2-12,
is
used
in
conjunction
with
the
Conditioning
Panel
when
the
BTS
provides
a
duplexed
forward
and
reverse
path
RF
connection.
The
Duplexing
Panel
separates
the
duplexed
forward
and
reverse
path
signals.
This
allows
the
BTS
to
be
connected
to
the
HU
which
has
separate
forward
and
reverse
path
RF
ports.
For
complete
information
about
the
Conditioning
Panel
and
Duplexing
Panel,
