LBI-39076B INTRODUCTION / DESCRIPTION
INTRODUCTION
This manual describes the installation, configuration,
and operation of the Enhanced Local Interconnect (ELI)
option. A companion manual, the Global Telephone
Interconnect (GTI) Configurator user's guide (LBI-39077),
describes how to use the GTI Configurator software to
configure the GTI units.
Although the objective of this manual is to provide
information in the order it should be needed, completely
read the applicable section before starting the installation or
configuration.

DESCRIPTION
OVERVIEW
The ELI option is a telephone switching system that
allows authorized radio users to make and receive telephone
interconnect calls on their EDACS radios without dispatcher
assistance. Under the direction of the Site Controller
computer, it can connect any one of up to 20 available
EDACS repeater channels to any one of up to 32 available
telephone lines, and maintain up to 20 interconnect calls at
any one time.

DESCRIPTION LBI-39076
B
The Site Controller computer directs up to 16 levels of
toll call restrictions, up to 15 rotary hunt sequences, 8 dequeuing priority levels, and inbound interconnect
enable/disable assignments, for each ID number. It also
accumulates interconnect call activity data for the System
Manager.
The standard ELI option consists of one or more GTI
units, one GTI Interface card, one set of two GTI
Configurator software diskettes, one set of two Site
Controller computer Personality PROMs, and the necessary
cables and hardware. The ELI option may also consist of an
optional Interconnect Ac counting Manage r (IAM) unit. The
GTI interface card is to be installed into one of the GTI units
making it the Master GTI.
The ELI option utilizes a distributed switching system
architecture that distributes the switching function between
the separate GTI units rather than concentrating it at a
centrally located telephone switch. Additionally, each GTI
unit receives its power from a separate repeater power
supply.
A typical ELI installation containing two GTI units, a
Master GTI, and an optional IAM is shown in
Figure 1. The function of each cable and bus
termination shown, is as follows (see parts list for part
numbers):
S - The serial data cables connect the Master GTI to the
Site Controller computer. (Two are used.)
GTI UNITS
Each GTI (Global Telephone Interconnect) unit
contains both a radio channel interface and a telephone line
interface. For each interface, the GTI contains both analogto-digital and digital-to-analog converters, and a digital
signal processor. The relation of these circuits to the audio
paths is shown in
Figure 2.
The radio channel interface provides the following
functions:
• Decodes DTMF from radio for radio-originated
call.
• Sends ringback or busy tone to radio for radio-
originated call.
• Sends ringing signal to radio for telephone-
originated call.

used if an IAM is supplied.)
A/P - The audio/power cable connects a GTI or Master
GTI to a MASTR II/III repeater and its power
supply. (One is used for each GTI or Master GTI
assigned to a MASTR II/III repeater.)
PCM - The PCM/Data bus sections connect each GTI,
the Master GTI, and the optional IAM in a daisychain. (Section lengths depend upon the position
of the units. The total number of bus sections is
one less than total number of units used.)
T - The termination for the PCM/Data bus terminates
the high channel end of the bus. (One is used.)
PCM / Data Bus
Figure 2 - GTI Audio Paths
The telephone line interface provides the following
functions for telephone-originated calls:
• Detects signaling from telephone line.
• Applies signaling to seize telephone line.
• Detects and decodes overdialed telephone number
digits from telephone line.
• Sends voice prompts to telephone line.
• Detects end-of-call signaling from telephone line.
• Removes signaling to drop telephone line.

LBI-39076B DESCRIPTION / INSTALLATION
The telephone line interface provides the following
functions for radio-originated calls:
• Applies signaling to seize telephone line.
• Detects signaling from telephone line.
• Generates and applies telephone number digits to
telephone line.
• Sends voice prompts to telephone line.
• Detects end-of-call signaling from telephone line.
• Removes signaling to drop telephone line.
One GTI converts the analog audio signal (from the
radio channel connected to it) into a digital signal for
placement onto the PCM/Data bus. Another GTI (or the
same GTI) converts the digital signal from the PCM/Data
bus back to an audio signal (for the telephone line connected
to it). A similar route is taken by the signal from the
telephone line to the radio channel. Each radio channel has
its own time slot on PCM/Data bus so as not to interfere
with any other radio channel.
print real-time records of calls being placed on the system.
Records can also be retrieved from the IAM at any time
using the PC-based GTI Configurator software. Call detail
records contain the following information:
• Record Type
• Start Time
• Elapsed Time
• Call Type
• Radio User ID
• Line Number
• Channel Number
• Phone Number Dialed (up to 20 digits)
• System Number
• Node Number
GTI INTERFACE BOARD
The GTI Interface board serves as the information and
command interface between the Site Controller computer
and all the GTI units in the system. It is installed in only
one GTI unit, which then becomes the Master GTI.
GTI CONFIGURATOR SOFTWARE
The GTI Configurator software is a PC-based, menudriven program (supplied in both 3.5-inch and 5.25-inch
floppy formats) that allows the system operator to change
parameters in the GTI database, retrieve GTI call records,
and monitor the system activity.
IAM
The optional IAM (Interconnect Accounting Manager)
is a microprocessor-based call-detail buffer, containing two
megabytes of battery-backed RAM to provide storage for up
to 60,000 call detail records, compatible with the EDACS
Billing Correlation Unit. At the completion of each call, a
call detail record of that call is sent to the IAM. The IAM
provides a serial data port for a printer to be connected, to
INSTALLATION
OVERVIEW
The installation of the ELI option has been divid ed into
14 steps, which are described in this section. Not all steps
will apply to all installations. Some steps involve more than
one activity.
Table 1 shows a flow chart of the installation activities
for various pieces of equipment. The activities to the right
of a heavy vertical line should not be started until all those
activities to the left of the line have been completed for that
piece of equipment. The number in a circle to the left of
each activity indicates the installation step in the text where
the activity is described.
These 14 installation steps plus the configuration of the
Site Controller database (contained in the Configuration
section of this manual) and the configuration of the GTI
database (contained in the GTI Configurator software user’s
guide) are summarized in the Installation Checklist at the
end of this manual. Make a copy of this checklist, and
check off items as they are completed.

2. SITE CONTROLLER HARDWARE
The
2nd step
the Site Controller computer is a VAX model. PDP models
will not support the ELI option. Since some PDP models
have been upgraded to a VAX model, you cannot tell if it is
a PDP or VAX from the outside. To know for sure, you
must look inside the PDP system chassis and check what
cards are installed. PDP models that have been upgraded to
a VAX model will have their cards arranged in the card cage
as shown in Figure 3.

The 4th step to install the ELI option, is to assign each
GTI unit (including the Master GTI) and the optional IAM
to a radio channel. Once this relationship is established, the
telephone interface inside the GTI units and the DIP
switches on the side of the GTI units can be set up. T hen
the GTI units can be mounted.
Although the optional IAM is not functionally
associated with any specific radio channel, it is mounted
with a specific radio channel as if it was. This forces it to be
in a predictable location relative to the GTI units so that
cables of the correct length can be provided for its
connection.
Until they are mounted there is an opportunity to get
them mixed up and mounted with the wrong radio channel.
To assure that this doesn’t happen, the radio channel
assignments can be temporarily marked on the GTI units, or
the GTI units can be set up and mounted one at a time.
The method used to assign GTI units to radio channels
is to assign all of the standard GTI units first, follo wed by
the Master GTI, and finally the optional IAM. Start by
assigning the first standard GTI to the highest numbered
radio channel, the next GTI to the next highest numbered
radio channel, and so on until all standard GTI units, then
the Master GTI, and finally the optional IAM (if supp lied)
are assigned.

You may use some other method. However, using the
method described here assures that the supplied cables will
be the correct length and the PCM/Data Bus will be as short
as possible. (The PCM/Data Bus must not exceed 120 feet
in length).
5. GTI SOFTWARE
The
5th step
that the insulating paper tab on the battery (RAM backup)
has been removed, and record the version number of all
software on each board in each GTI unit. Each regular GTI
unit has a Main board and a Processor board. One regular
GTI unit is made into a Master GTI unit by adding a third
board, the Interface board. Keep this information with this
manual for future reference. If a problem is later
encountered with the equipment, this information may be
essential to help with the diagnosis.
Main Board
to install the ELI option is to make sure
NOTE
Revision-A Main boards do not support
narrowband systems. If you have a narrowband
system, you must use revision-D or later Main
boards.
Revision-A Main boards
CAUTION
Revision-A Main boards require version 1.x
GTI 552 and GTI DSP software. Do not use
version 2.x or higher GTI 552 or GTI DSP
software with revision-A Main boards.
For a revision-A Main board, the GTI 552 software is
stored in U63 and requires version 1.x software (where x =
any number). A sample label for U63 is shown in Figure 11.

The
6th step
each GTI telephone interface to match the type of telephone
circuit to be connected to it. The first Main boards,
identified by the manufacturer’s number 702-9588A, are
configured differently than the later Main boards, identified
by the manufacturer’s number 702-9588D or E. The boards
are referred to as revision-A Main boards and revision-D or
E Main boards respectively.
to install the ELI option is to configure
NOTE
Revision A Main boards do not support Direct
Inward Dial (DID) telephone lines. If you need
to have a DID telephone line connected to a GTI
unit, that GTI unit must contain a revision-D or
later Main board.
Revision-A Main Board
The revision-A Main board uses 15 jumpers (JP1
through JP15) and two fuses (F2 and F3) to configure the
telephone interface. Set the jumpers and fuses to match the
type of circuit to be connected to it. Figure 18 shows the
locations of these jumpers and fuses on the revision-A Main
board, and Table 2 lists the jumper and fuse configurations
for four common types of telephone circuits. Figure 19
through Figure 22 show simplified schematics of these four
configurations.
Many other configurations of the GTI telephone
interface are possible. Table 3 shows which jumpers and
fuses to use to obtain each specific interface characteristic.
Figure 23 shows a simplified schematic of the interface,
including key components and the location of each jumper
and fuse. If a jumper or fuse is not specifically required for
a characteristic, remove it. Not all characteristics are
compatible with each other. For example, the interface
cannot be configured for a -48 V reference for the E-Lead
and at the same time be configured for an external reference
for the M-Lead.
Table 2 - Configurations by Line Type (Rev A Main Board)
Be careful of terms when talking or reading about the
telephone circuit that the GTI unit is to interface. Terms
such as send, receive, in, out, E-Lead, and M-Lead are
sometimes defined differently by different people and from
different points of reference. T he terms used in this manual
are defined as follows:
• 4-Wire Send - audio voice signals fr om GTI unit to
telephone circuit.
• 4-Wire Rec - audio voice signals from telephone
circuit to GTI unit.
• M-Lead - telephone circuit supervision signal from
GTI unit to telephone circuit.
• E-Lead - telephone circuit supervision signal from
telephone circuit to GTI unit.
