The
door
entry
system
however
will
not
make
any
difference
in
calls
perceived
from
the
doorphone
stations
and
will
ring
home
phones
the
same
way,
no
matter
which
doorphone
initiated
the
call.
If
the
user
does
not
require
door
release
ability
from
the
system,
recognizing
calls
from
a
specific
doorphone
is
no
longer
critical.
The
user
may
always
ask
the
guest
as
needed
to
identify
the
entrance
he/she
is
using.
However,
if
door
recognition
is
required,
the
door
entry
system
will
provide
such
an
ability
with
the
addition
of
the
QX-3
module.
The
QX-3
module
individualizes
the
doorphone
stations
but
still
obliterates
the
need
for
door
recognition
by
allowing
the
user,
for
the
one
part,
to
use
the
same
keystroke
on
phone
keypad
to
release
any
one
of
the
doors,
and
for
the
other,
by
automatically
connecting
the
correct
doorphone
on
call
pickup.
In
all,
the
QX-3
module
does
provide
direct
door
identification
by
implementing
distinctive
notes
from
the
door
chime
box:
one
chime
note
for
door
1,
two
notes
for
door
2,
etc.
