Information
Before
installing
the equipment,
verify
the characteristics
of leased telephone
lines
with
the
company
providing
the service.
The audio wireline(s) for
nonsecure
stations must meet the
following
specifications for acceptable radio
communications.

for line impedance tolerance
of
+100% to -50% from nominal impedance of
600
or
900
Q.
The impedance
tolerance
only applies
to
two-wire
tone remote control stations
in which
the
level from
the remote console is
lower than
22
dB below
the
level of
outgoing receiver line audio
(e.g,
line loss greater than
22
dB).
The audio wireline(s) for
secure stations require
a
3002,
D-conditioned phone line.
The control wireline may
be
installed prior
to
cabinet installation and terminated
near the location chosen for the station.
Conduit
or
two-wire
cable can be used
from this termination to the Junction Box wireline interface connections.
The following special
tools are required
during installation.
