INSTALLATION
PSTN
CONNECTION
The
installation
should
be
done
at
a
location
that
has
an
available
PSTN
connection
such
as
a
standard
copper
pair,
digital
PBX
with
an
ATA
(analog
telephone
adapter)
connection,
or
VOIP
telephone
service
ATA
such
as
Vonage
or
MagicJack.
Most
telephone
connections
that
have
a
ring
voltage
and
“tip
and
ring”
connections
(also
referred
to
as
2
‐
wire)
should
work
with
the
NEXLINK
gateway.
This
connection
is
plugged
into
the
port
labeled
TELCO
on
the
gateway.
RADIO
RF
PATH
The
RF
path
to
and
from
the
repeater
site
needs
to
have
a
solid
signal
to
and
from
the
radio
connected
to
the
gateway.
It
is
not
necessary
for
the
radio
and
the
NEXLINK
gateway
to
be
located
at
the
tower
site.
For
instance,
a
radio
located
at
a
service
dispatch
area
with
an
outside
antenna
that
has
a
solid
signal
to
and
from
the
repeater
is
perfect.
If
the
radio
is
to
be
located
at
the
tower
site,
then
the
appropriate
measures
should
be
taken
to
ensure
a
solid
and
balanced
RF
connection.
Before
connecting
the
gateway
to
the
radio,
make
sure
that
all
programmed
zones
in
the
radio
have
a
clear
transmit
and
receive
path
and
the
programmed
ID’s
and
zones
are
the
desired
user/groups
to
be
used
with
the
gateway.
PLUG
AND
PLAY
CABLE
CONNECTIONS
The
NEXLINK
gateway
comes
complete
with
all
the
cables
required
for
connection
to
the
Kenwood
NX
‐
700
or
NX
‐
800
radio.
Plug
the
cable
harness
as
shown
in
Fig
1.
MIC
GAIN
SETTING
The
MIC
GAIN
on
the
front
panel
of
the
gateway
should
be
set
at
about
10:00
using
the
indentation
on
the
shaft
of
the
control.
This
control
adjusts
the
level
of
audio
that
is
sent
out
over
the
air
to
the
repeater
from
the
user
on
the
TELCO
port
of
the
gateway.
This
setting
may
vary
slightly
depending
on
the
installation.
This
level
should
be
set
so
that
the
user
of
the
gateway
sounds
almost
the
same
as
all
other
users
on
the
system.
