4.Mounting ProcedureUnpack and carefully inspect all equipment for
shipping damage. Notify the shipper immediately
of any damages found. Verify that the packages
contain all parts and accessories needed for proper
installation and operation.
If a backboard is required at the mounting location,
attach it securely to provide a stable mounting
surface for the equipment.
Refer to Figure 3-1 or to the 
PPO32-000 mounting
template included in the literature that
accompanies the common equipment cabinet for
the locating dimensions required for the three
mounting screws, and mark their locations on the
mounting surface.
Drill holes in the mounting surface of a proper size
to accommodate the hardware being used. If
necessary, prepare these holes with inserts,
anchors or other attachment devices as dictated by
the type of mounting surface.

a.Insert the two top screws into the mounting surface
and tighten them to within approximately 
l/8-inch
of the surface.
Hang the cabinet on the top screws using the
mounting holes located on the rear of the cabinet.
Note that these holes are elongated with an
enlargement at one end. This feature allows the
cabinet to snap down on the screws to secure the
mounting when the cabinet is hung on them.
insert a third screw through the mounting tab
located on the lower edge of the cabinet and into
the mounting surface, and tighten it into place.
Place the individual telephone stations as desired
and in keeping with accepted industry and off ice
standards. A telephone station can be wall
mounted if necessary as they are desk/wall
reversible. Refer to Chapter 6, Maintenance, for
instructions in preparing a desk/wall reversible
station for wail mounting.

AC Power Connection
Employ a dedicated 117VAC 15 AMP circuit, with a
third-wire ground, supplied to a standard electrical
outlet (NEMA 
5-15R) for the AC power connection.
AC power connection is illustrated in 
Figure 3-2
shown below.
0 For added equipment protection, connect a plug-in
power line surge protector between the power cord
and the AC outlet.
0 Thoroughly check out the installation before
connecting the power cord to an electrical outlet to
apply AC power to the system.
Battery Back-Up
The common equipment provides an interface
connector for the connection an optional external
battery assembly. Several different assemblies are
available separately as kiis (product codes BBU02,BBL02, 
and-BBL03). ..
Be sure that the AC power cord is
connected to the electrical outlet before
connecting an external battery assembly to
the common equipment interface
connector. This ensures that internal
protection circuitry is operating to prevent
damage that could result from improper
connection.
The optional external battery assembly provides a
minimum of one hour of operation should the AC
power to the system be interrupted. The BBU02 and
BBL02 assemblies have a 15 ampere-hour current
rating and the 
BBLOB assembly has a 25 ampere-hour
current rating.
The BBU02 
and BBL02 external battery assemblies
may include batteries from either of the following
suppliers:
- Model PS-12150 from Power-Sonic Corporation,
Redwood City CA, 94032
- Model PE12V15 from GS PORTAIAC,
City Of Industry CA, 91748
The BBL03 external battery assembly may include
batteries from the following supplier:
- Dynasty JC12-250 from Johnson Controls Inc.,
Milwaukee WS, 53212
As discussed previously in the page 3-1 paragraph
titled Special Mounting Consideration, you must mount
the BBU02 assembly, the common equipment cabinet,
and all the wiring in a “dedicated equipment room”.
The BBL02 and BBL03 assemblies consist of a closed
metal cabinet, a pair of batteries, panel-mounted
fuses, and a cable that connects the battery back-up
unit to the telephone system. This cable is secured to
the cabinet by a strain-relief. This model is safe forinstallation in general off ice environments 
and does
not need to be installed in a “dedicated equipment
room.”
The minimum battery backup time for a fully
configured system can be calculated. The formula for
doing this is:
T = 1 + [(O? (N)]
T = Back-up time in hours
K = Constant
0.9 for GO408 with or without a GM408 module
0.8 for GO81 6 with or without GM408 modules
0.8 for G1632 with or without GM408 modules
e 
= Ampere-hour capacity of battery (BBU02 = 15)
N 
= total number of stations
Example:
Assume that a Cl832 system plus two CM408
modules are installed along with a BBU02 battery
assembly to provide back-up power.
(8.8) (I 5)
T = 1 + [(O.l) (48)]12= 5.8= 2.1 Hours
0 During AC operation, the common equipment
provides recharging current to maintain the voltage
potential of the external battery assembly at an
operational level. The charging circuit may not
provide an adequate charge if an installed battery
assembly has a current rating of greater than 40
ampere-hours.
NOTE: An optional external battery assembly requires
approximately 10 hours to completely
re-charge to full potential after it has been,
completely discharged and, in some cases,when initially installed.
System Grounding
The common equipment cabinet has internal
secondary surge protection on all line ports. In order
for this protection to be effective, the cabinet 
MUST be
connected to a reliable earth ground such as a metal
cold water pipe or a building frame ground. The
grounding wire must be of 
#lO or #12 insulated, solid
copper and separate from the three-wire AC line cord.
A ground stud is located on the common equipment
cabinet for this purpose. System grounding is,
illustrated in 
Figure 3-2,
If spare conductors exist in the cables that are run
between the station and the 
86M-xx connector blocks,
it is good practice to connect them to earth ground.
Doing this may help prevent them from inducing radio
frequency and/or AC interference into the system. It is
also good practice to disconnect any unused station
jacks from the connector block and ground that wiring
to earth ground as well.

Line Connections
The line terminations for the common equipment
cabinet are standard modular plug/jack connections.
Each modular jack provides termination for two lines.
Modular line jacks 1 and 2 also provide termination for
an auxiliary pair in addition to the two outside lines.
The outside line termination can be a type 
66M-xx
connector block or individual 
6-position modular jacks.
The line cord that is routed between the outside line
termination and the common equipment termination
should be twisted-pair wiring. 
Table 3-I shows the
line connection details for all three of the common
equipment base units. 
Figure 3-4 illustrates typical
line connections. The G0406, GO61 6 and G1632
common equipment supports the installation of up to
4, 6, or 16 lines respectively. Add-on expansion
modules are available to expand the line capacity 
of
the systems.
After you have initially connected a line to a particular
line port and programmed its attributes (or left it with
the system defaulted values), you can reassign the
line and its attributes to a different port by
programming action if you wish. This feature allows
you to make adds, moves, and changes without
relocating the line wiring. Refer to Chapter 4 for the
line to line port reassignment programming details.Line Grounding
Transient voltage spikes, if induced onto CO or
CENTREX lines, can travel through the cable and into
the common equipment. The telephone company
offers basic protection against this condition but it is
usually designed to protect the central office circuits.
While it will also provide some protection to the
common equipment, it should not be relied upon for
total protection. To help ensure that external
overvoltage surges do not damage the system, the
manufacturer recommends that gas discharge tubes,
or similar primary protection devices, be installed and
properly grounded on all lines (a selection of
solid-state protection devices for this purpose is
available from ITW Linx, Elk Grove Village, Illinois
60007).

The digital telephone system supports the operation of
the following proprietary digital station types:
0 Multiline Telephones
0 LCD Speakerphones
0 DSS/BLF Consoles
0 Single-Line and Multiline Proprietary Telephones
Software Revision Considerations
A digital telephone system when equipped with Snnnn
software cartridges at any software revision level
provides support for the following DigiTech
telephones: product code 7714X, 
7714s and 7700s
with a revision letter of A through H. At software
release 8, support was added for the DigiTech 
DD32X
DSSiBLF console.
Wiih the Snnnn software cartridge at software release
10, the digital telephone systemalso supports the
newer DigiTech telephones with a product code
7714X, 
7714s and 7700s at a revision letter of I and
later. You need to consider the following items when
installing the revision I and later telephones.
ti While the system when equipped with an Snnnn
cartridge at software release 10 and later supports the
use of all DigiTech telephones regardless of their
revision letters, a system with an Snnnn cartridge at
software release of 
9 or earlier will not support the
revision I and later telephones. In other words,
whenever a system includes revision I or later
DigiTech telephones, be sure that the system software
release is at 10 or later.
(/ Always program station ports to provide ringing line
preference to revision I and later telephones that are
connected there. This action is necessary before the
orange LED feature can become active.
With the Snnnn cartridge at’software release 11 A, the
digital telephone system provides support for the
proprietary single-line digital telephone (product code
7701 
X).
With software release 
128 in lnnnn software
cartridges, the digital telephone system provides
support for all DigiTech telephones and 
DSS/BLF
console plus support for Comdial 
Impact telephones
and 
DSS/BLF console with product codes of 8024,
8012, 8112, 8101, and 
IB64X beginning with a revision
letter of A.
With software release 
138 on lnnnn cartridges, the
system adds support for the 
lrrrpac~ 8112N multiline
proprietary telephone and the Americom telephones
and consoles with product codes of 711 OX, 701 OS,
7016S, XD64X, and XDA16 to the support already
provided for all DigiTech and 
Impact telephones.
Station Installation
The G0408, GO81 6 and G1632 common equipment
supports the installation of up to 8, 16, or 32
telephones respectively. Add-on expansion modules
are available to expand the station capacity of the
systems.
Connections between the common equipment and the
stations are typically via type 
66M-xx connector blocks
which are cable connected to the common equipment
50-pin male connector. The connector block is, in
turn, wired to modular jacks that accept the modular
line cord connected between it and the telephones.
The maximum distance allowed from the common
equipment to the stations is per the following list:
0 Multiline Telephones - 1000 feet using #24 gauge,
twisted-pair cable or 2000 feet using 
#22 gauge
cable
0 Single-Line Telephones - 1500 feet using #24
gauge, twisted-pair cable
When installing the system telephones keep in mind
that each station port supports only one proprietary
telephone and the system does not allow you to bridge
two stations to a single modular jack.
Grounding Considerations
Remember, if spare conductors exist in the cables that
run between the stations and the 
66M-xx connector
blocks, it is good practice to connect them to earth
ground. Doing this may help prevent them from
introducing radio frequency and/or AC interference
into the system. Also remember that it is good
practice to disconnect any unused station jacks from
the connector block and ground that wiring to earth
ground as well.
Station Relocation
The digital proprietary telephones identify their
telephone type to the system when you install them.
The system assigns an extension number and all other
programmable attributes to station ports as a default
that you can reprogram them as needed. Plus, you
can use programming action to reassign attributes of
one station port to a different station port if you wish.
This station relocation feature allows you to do adds,
moves and changes without relocating the station
wiring. Refer to the automatic station relocation
programming procedure and the station-to-station
programming procedure found in Chapter 4.
NOTE: The station 10 to station port 10 assignment
can not be 
relocated.

Installation
Cable Clips
Each cabinet-mounted 50-pin male connector is
equipped with a retaining clip. This clip is designed to
secure the mated connection once it is made. The clip
does this by snapping into a slot on the cable-mounted
connector when it is pressed together with the
cabinet-mounted connector. This retaining clip must
be pulled back slightly to unsnap it before the
connectors can be separated.
Auxiliary Jack
(Impectand DiglTech LCD speakerphones with
product code of 80248 and T7OOS rev I and later)
The auxiliary jack (available on impact 80248 and
DigiTech 
7700s Rev. I and later LCD speakerphones)
will support the use of the following devices: a
headset, a tape recorder, an external ringer, or an
external paging device.
The auxiliary jack is a 
4-position 616~type handset jack
that provides the following connections:
0 positions 2 and 3 = output from system
to external device
0 positions 1 and 4 = input to system from
headset’s microphone
At any given time, the auxiliary jack will serve
whichever external device that is listed in its display
but it will serve only one of those devices at a time.
The user must program a separate enable/disable
button for each external device that he or she plans to
connect to the auxiliary jack. When a user presses aparticular enable button that he or she has
programmed, that device is the one that is active and
named in the display.
If an external device requires power for its operation,
you must install an external source to supply it.The
system does not supply any power through the
telephone’s 
auxiliaryjack. The auxiliary jack is an
audio output source for the external ringer, external
paging device, and tape recorder. The jack will accept
an audio input signal from the headset microphone
during headset operation but it is not designed to
receive signals from any other external device or from
a telephone line.
piiicq
With the exception of a headset
microphone, do not connect the audio
output of any external device to the
auxiliary jack. Also, do not connect the tip
and ring leads of a telephone line to the
auxiliary jack. Do not connect any devices
to the auxiliary jack other than those
mentioned in the telephone user’s guide.
You should caution the telephone users
about this fact as well.
If a user needs to connect a tape recorder to his or her
telephone’s auxiliary jack, you must obtain a special
recorder cable made for this purpose from your normal
distribution outlets:
