An extender card can be purchased as an
option and may be part of your system. It
consists of 4 pieces: two ribbon cables and
two interface boards.
In some cases you may have purchased a
Tone Detection Card. It is an option and in
most cases will not be present.
Mounting
The ISS is rack-mountable, requiring three
standard rack spaces (5.25") in a standard
EIA 19.00" rack. Ensure that air flow is
maintained, especially on the right side
(when looking from the front) where the ISS
power supply section is located. A good
basic rule to remember is that most elec-
tronic equipment failures are power supply
related. Power supplies tend to generate
heat which, when not adequately dissi-
pated, serve to cook the power supply,
drying out electrolytic capacitors and
stressing semiconductor junctions. Keeping
all equipment relatively cool will reduce the
likelihood of problems occurring.
Connecting the Unit to Power
The ISS may be operated from either nomi-
nal 115 or 230Vac, 50/60 Hz. Units selected
for 115V operation utilize a 0.75A 3AG
Slow-Blow fuse; 230V operation utilizes a
0.375A Slow-Blow fuse. Before connecting
the ISS to power, determine the actual line
voltage and check to see that the voltage
selector switch, visible through the square
cutout in the Transfer Relay Assembly, is
set to the appropriate voltage. If the voltage
selector switch is set for 230V, ensure that
the fuse, located adjacent to the voltage
selector switch, is 0.375A. PLEASE NOTE
THAT AN INCORRECT SETTING AND/OR
INCORRECT FUSE COULD SERIOUSLY
DAMAGE THE UNIT.
The ISS utilizes an IEC standard connector
to mate with the line cord. The line cord
supplied has a North American standard
plug at one end and an IEC connector at
the other. In non-North American applica-
tions, the plug must be cut off and an ap-
propriate plug attached. The wire colors in
the line cord conform to the internationally
recognized CEE color code and should be
wired accordingly:

Signal Connections
All signal connections to and from the ISS
are made via connectors located on the
back panel. Four, three pin XL-type connec-
tors handle audio input and output signals;
female for input, male for output. One
25-pin male D-type subminiature connector
handles all remote control and status sig-
nals. Refer to Figure 1, located at the end
of this manual, for detailed connection
information.
Audio Signals
Left and right audio input and output con-
nections must be made. For hum, noise,
