This manual provides instructions for configuring the
Ericsson GE Trunking Card Shelf (GETC), part number
19D901868G3 and G4, for Station (including repeater an d
SCAT), Satellite Site Receiver, and VDI Control operation.
This manual is applicable to GETC (pronounced “getsee”) hardware platforms installed in wideband or narrow
band 800 MHz, 900 MHz, UHF, and VHF stations. The
information presented includes an operational description
and procedures for installing, upgrading, and verifying the
hardware and software installed in the GETC.
The Lightning GETC (GETC1e) platform consists of
the following sub-assemblies:
• Logic Board 19D904266G1 (used with Group 3
shelf) or 19D904266G4 (used with Group 4 shelf).
• GETC Expansion Module (Turbo Board)
19D903536P1.
• Regulator Board 19C366861G2.
• Rockwell Modem 19A705178P1 (optional). (The
modem is required when the GETC is used in an
EDACS Voted or Simulcast System or if it is part
of an EDACS Network)
• GETC EPROM (U2) 349A9607G5 (Ver. 5.04).
349A9607G5 SOFTWARE
The 349A9607G5 software release adds the following
features to GETC operation:
• SCAT Data (Refer to LBI-38987)
• Pro-Sound
• Enhanced MultiSite Login
• Voted Digital Interconnect (Refer to LBI-39187)
SCAT Data
Release 5 Station GETC software adds SCAT
functionality to the Station GETC. This includes the SCAT
RF and Landline Data functions. The former SCAT GETC
software 344A3835G2 is replaced with 349A9607G5 and
its former Turbo software 344A4414G4 is replaced by Link
Turbo software 344A4414G5.
NOTE
NOTE
In conjunction with this software release, the
SCAT Downlink GETC software 344A3835G2
and Turbo Board software 344A4414G4 is
replaced by Link software 344A4895G5 and Turbo
software 350A1121G5, respectively. Refer to LBI-
38987 for details.
All references to GETC in this manual refer to the
GETC1e platform and the combination of GETC Logic
board and Turbo board installed in the GETC Shelf.
SOFTWARE FEATURES
The GETC software product is continuously being
improved and upgraded to include new features. The
following paragraphs provide brief descriptions of the new
features introduced by recent software releases.
Information is also provided when hardware or software
issues affect the GETC’s configuration.
For a complete description of the new or enhanced
features and its use, refer to Software Release Notes (SRN)
for the specific software release. For example, to review
release notes covering 349A9607G4 software refer to
SRN1060-4, for 349A9607G5 software refer to SRN10605, etc.
Configuration Considerations:
• Radio users must have SCAT options enabled.
• When selecting Landline data, a Rockwell modem
must be installed and EDG must be set up (refer to
EDG documentation).
• Configuration requires using PC Programmer
V4.03 and Field Macro “gtc_9505.mac” to
access applicable parameters.
Refer to LBI-38987 for complete details on configuring
SCAT systems.
Pro-Sound
The GETC Group 5 Release adds the EDACS ProSound Feature. Pro-Sound provides better end-to-end audio
quality by providing radios with a list of alternative sites
and their corresponding control channels through the use of
“adjacency information”.
The GETC has the following role in supporting the
Pro-Sound Feature:
6Rev. B
SOFTWARE FEATURESLBI-38988
• Receive Adjacency information from the Site
Controller or Downlink.
• Count the number of actual Adjacent Systems
listed in the Adjacency Message.
• Build an Adjacencies Table Length Definition
Message and send it.
• If a Priority System is defined, build a Priority
System Definition Message and send it.
• For each Adjacent System, build an Adjacent
System Definition Message and send it.
• The Control Channel expects an Adjacency Data
update from the IMC every 25 seconds or sooner.
• The Control Channel will stop sending Adjacency
Data if the Link to the IMC breaks, or if it waits
longer than 30 seconds for an adjacency
information update from the IMC.
• If the Link to the IMC breaks, after it recovers, the
CC will wait for a fresh set of Adjacency Data
before it will begin sending over-the-air (RF)
Adjacency Data.
Radio users must ensure the radio’s personality has
“Pro-Sound” enabled and the radio feature encryption
option “wide area scan” or “priority scan” is active.
1. A particular site color is programmed in the
Control Channel GETC.
2. The outbound Control Channel messaging tells the
radio which “color” to use on inbound
transmissions.
3. Inbound transmissions from the radio to the
Control and Working Channel are coded with
correct color.
Users must have radio’s software upgraded to support
this feature.
Configuration Considerations
• The Enhanced Multi-Site Login feature does not
require any hardware changes. However, it does
require special configuration of the GETC
software.
• To enable Enhanced Multi-Site Login, the “Site
Color” parameter needs to be programmed into the
GETC Personality. This feature is a Personality
Extended Site Option loaded into the PC
Programmer software via the Field Macro file
“gtc_9505.mac.” Refer to the Personality
Programming section in this manual for additional
information on Field Macro installation into the
PC Programmer, TQ-3357.
Configuration Considerations
Pro-Sound does not require any hardware changes or
special software configuration. The feature is activated
from the MOM PC, which is connected to the IMC.
Enhanced Multi-Site Login
The Enhanced Multi-Site Login feature provides a
method to enhance signaling integrity, on both the inbound
Control Channel and Working Channel, in an environment
where a distant site is operating with the same frequency
set or where intermodulation interference is a
consideration.
Enhanced Multi-Site Login is achieved by means of a
digital “color code” on the inbound Control and Working
Channel signaling. The CRC (BCH error correction),
which is appended to the end of each message, is coded (by
the radio) and decoded (by the GETC) in a unique way as
determined by the color specified in the GETC personality.
This allows the specified site (i.e. having the correct site
color) to acknowledge the receiving a radio transmission in
an area where many sites may also receive the
transmission. This is implemented as follows:
NOTE
NOTE
Only PC Programmer TQ-3357 V4.03 (or later)
can be upgraded through the use of Field Macros.
Current Field Macros may be downloaded from
the accompanying Station Turbo Software
distribution disk or from Ericsson’s “One1Call”
Electronic Information Retrieval system.
Voted Digital Interconnect
The Voted Digital Interconnect (VDI) feature allows
Voted and Simulcast sites to have access to the digital
Central Interconnect system, Jessica.
For a Voted (Non-Simulcast) system, an additional
GETC per channel is required, making the configuration
more like that of a Simulcast system. All GETCs attached
to RF receivers will operate as Satellite Receivers, and the
added Control GETC will take on transmit responsibilities
similar to those of the Simulcast Control Point GETC. The
main purpose of the additional GETC is to provide a
synchronous data input port which can be connected to the
output of the voter. This provides the Control GETC the
Rev. B7
LBI-38988SOFTWARE FEATURES
capability of listening to both the IMC and the Voter
simultaneously.
For a Simulcast system, no additional equipment is
required once the system is equipped for Digital Dispatch.
A wiring modification is made to the digital path between
the Voter Selector and the Control Point GETC to provide a
continuous data path between them. The modification
gives the Control Point GETC the capability of listening to
both IMC and the Voter Simultaneously.
Configuration Considerations:
• Configuration of the GETC Personality requires
using PC Programmer V4.03 and Field Macro
“gtc_9505.mac” or V5.0.
Refer to LBI-39187 for complete details on configuring
GETCs for VDI systems. Additional information on Voted
Digital Interconnect is also available in the Voter and
Simulcast Control Point Maintenance Manuals, LBI-39149
and 39186.
DIP Switch Changes
The functionality of the DIP switches S1, S2, S3 have
been dramatically reduced. Many of these controls now
reside within the GETC personality and may be modified
using GETC PC programmer TQ-3357.
The following controls have been altered:
• Simulcast operation moved to personality space.
• Conventional Failsoft enable moved to personality
space.
In earlier software versions, the operating frequency
for MII/IIe systems was set into the DIP switches. With the
introduction of 349A9607G5 the MII/IIe and MIII systems
frequency is programmed in personality. MII/IIe use this
information for frequency synthesizer loading and
Narrowband systems extract even/odd information. The PC
programmer V4.03 does not accept UHF frequencies and,
as a result, UHF systems must have a fixed offset of 500
MHz added since only the even or odd frequency
information is needed.
349A9607G4 SOFTWARE
With the release of 349A9607G4 software, both
Wideband 9600 baud functionality and Narrow Band 4800
baud functionality were merged together. This release also
included three new features:
• Failsoft Patch
• Wideband Power Monitoring
• Channel Activity Logging
In addition, this software release was designed in
conjunction with the GETC PC Programmer TQ-3357
V4.03 (344A3466G5).
Multisite Digital Voice or Digital Data
Digital Voice or Digital Data applications require
installation of a Rockwell Modem. This allows the GETC
to send and receive Digital Voice or Digital Data
information, encoded as 9600 baud modem data, to the
CEC/IMC using the four-wire audio line.
• Frequency selection moved to personality space.
• Personality programming through J104 only (J100
no longer used for programming).
8Rev. B
Additionally, the personality option for Wide Area
Digital Voice must be ENABLED for proper operation.
This can only be done using the PC Programmer V4.03 (or
later).

LBI-38988DESCRIPTION
DESCRIPTION
The Station GETC is the foundation of all EDACS
trunking operations. It is capable of operating in the
Trunked Failsoft mode or as part of a fully trunked system
or network. In the Trunked Failsoft mode, one of the
Station GETCs operates as the Control Channel GETC,
providing the command and control link between the
mobile radios and the EDACS system. The remaining
station GETCs operate as Working Channel GETCs and
enable or disable selected repeater channels for the actual
voice or digital data communication. Each Station GETC
has the ability to operate as a Control Channel if the
operation of the current Control Channel GETC is
interrupted.
In a Fully Trunked EDACS network or system (Figure
1), the Station GETCs function as either Control Channel
or Working Channel GETCs. In this environment, the Site
Controller Computer directs all communications, and
designates the Control Channel and Working Channel
GETC's. This allows EDACS to provide advanced features
such as Dynamic Transmission/Message Trunking, Local
Telephone Interconnect, Activity Logs, and Management
functions.
However, should the Site Controller fail, the EDACS
system defaults to the Trunked Failsoft mode. In this
mode, one of the GETCs assumes the role of Control
Channel GETC and directs Working Channel assignments
using the Backup Serial Link (BSL). Should the Control
Channel GETC fail, one of the other Working Channel
GETCs assumes the Control Channel function. The end
result is reliable, high performance trunked
communication.
The Downlink GETC provides the communication
path between the site and the Integrated Multisite and
Console Controller (IMC) or the Console Electronics
Controller (CEC) via the Uplink or Link GETC. Refer to
LBI-38896 when configuring Downlink and Uplink
GETCs.
OPERATION
The Station GETC communicates with the Site
Controller through an RS-232C port (J100), see the
Interconnect Diagrams, operating at 19.2K baud.
Additional communications parameters are one start bit,
eight data bits, and one stop bit.
The designated Control Channel GETC communicates
with the Working Channel GETC's using a Sync line that
indicates outbound Control Channel data and inbound
mobile data. The Sync line is connected in a bus fashion to
each Station GETC.
CONTROL CHANNEL
The Control Channel GETC provides continuous
outbound Control Channel data. The data stream consists
of message frames containing information such as Channel
Assignments. The Channel Assignment message includes
the originating mobile's LID, communication type,
Trunking mode, communications channel, and the group or
individual involved in the call.
The mobile radios synchronize their transmissions on
the Control Channel to reduce Control Channel collisions.
The designated Control Channel GETC processes the
inbound data prior to passing the data along to the Site
Controller. When operating in the Failsoft mode, the
Control Channel GETC also produces the required Channel
Assignments.
Control Channel Jamming
Whenever an invalid signal is present on the inbound
Control Channel for longer than six seconds, the Control
Channel GETC generates a jamming alarm . The Station
sends the alarm to the Site Controller which can initiate
corrective action such as re-assigning the Control Channel
to a different operating frequency.
WORKING CHANNEL
Sub audible signaling or Low Speed Data (LSD) is
present on the Working Channel along with the primary
voice communication. The LSD indicates group call
activity on other channels and also indicates a channel drop
when appropriate.
The Working Channel operates in either the
Transmission Trunked mode or Message Trunked mode.
Transmission Trunking allows for an instantaneous
channel drop upon receipt of an "unkey" message from the
mobile radio. This is the most efficient use of channel
resources.
Message Trunking provides hang time following the
channel drop message. This mode is used when it is
important to provide uninterrupted communication. When
using Message Trunking, the user(s) occupy the same
Working Channel until the message trunk timer expires.
TRUNKED FAILSOFT OPERATION
The Trunked Failsoft operating mode provides basic
trunked communications. The designated Control Channel
GETC makes all channel assignments and transmits the
assignments over the BSL (J102-3) to each of the Working
Channel GETCs. The Failsoft operating mode is entered

HARDWARE INSTALLATION
Typically, a Station GETC is installed in a n EDACS
station cabinet just above each of the station's radio
assemblies as shown in Figure 2. The assembly is mounted
within a slide out shelf measuring 1.75 inches (one rack
unit) high by 19 inches wide.
Installation or removal of the shelf sub-assemblies
involves sliding the GETC shelf out of the cabinet and into
the service position. This position allows access to the
shelf's sub-assemblies. Install all components with the
appropriate screws, nuts, and washer hardware. Refer to
the MASTR IIe (LBI-38430) or MASTR III (LBI-38636)
Application Assembly Diagrams for detailed information
on installing the GETC Shelf.
Observe basic safety precautions to prevent injury or
equipment damage.
Upgrading Hardware
GETC Shelves 19D901868G3 which are upgrading to
the 349A9607G4 or G5 software must ensure their
hardware is upgraded to the proper level. (The
19D901868G4 GETC Shelf meets all Group 5
requirements.)
Upgrading the hardware involves three elements:
• The microprocessor U1, 19A705557P1 (80C32), is
replaced with a faster “Speedy” microprocessor
RYT 121 6060/A (80C320).
• Replacing the AMPS modem chips U4 and U19
with the TI AMPS modem chips 19A704727P4.
• Installing a Ferrite Toroid on the Turbo Board
harness to suppress EMI spurs at 74 MHz.
The replacement microprocessor and Ferrite Toroid are
available in the field installable upgrade kit SPK9505. If
replacement of the modem chips is necessary, they must be
ordered separately. Refer to LBI-38894 and LBI-38822 for
complete installation instructions.

Rockwell Modem Installation
The Rockwell Modem provides a high speed
synchronous serial interface between the Station GETC and
the CEC/IMC's Uplink GETC. The Station GETC uses the
modem to send and receive serial digital data representing
GID information, polling messages, keying messages, and
channel assignments. Data transfer rates are 9600 bits per
second (bps) using dedicated 3002 data grade four-wire
audio lines. Technical specifications for the modem may be
found in LBI-33031. Information on installing and testing
the modem may be found in LBI-38894, and LBI-38822.
Modem Alignment
Use the following steps to set up the basic audio line
levels. If the Station GETC is linked to a MultiSite system
other than the CEC/IMC (i.e. Data Gateway), different
levels may be required. Consult the applicable system
installation manual for the required levels.
1. Ensure jumpers are installed on J11 pins 1 & 2
and J12 pins 1 & 2.
2. Apply power to the GETC.
3. Adjust the receive level by monitoring U18 pin 1
(refer to Figures 3 and 4) and adjusting the receive
level potentiometer R1 (located on the GETC
Logic Board) for 400 mVpp as measured with a n
oscilloscope (85 mVrms if using an RMS
Voltmeter).
4. Verify the presence of demodulated signal data at
TP107.
5. Adjust the transmit level potentiometer R2 for the
maximum output level allowed by the phone line,
microwave link, or equivalent communication
line. For telephone lines linking the Station

NOTE
To switch a GETC from the Control Channel
operation to Working Channel operation, press
and hold S4 on the Control Channel GETC. This
causes the Failsoft System to re-assign the Control
Channel responsibilities to the next functioning
GETC. Release S4 and verify LEDs.
2. Place Clear Voice calls on both wideband or
narrowband channels and Digital Voice calls on
the wideband channels to verify correct operation.
3. Verify LED indicators are correct, as shown in

TROUBLESHOOTINGLBI-38988
TROUBLESHOOTING
The hardware used in the GETC is extremely reliable,
making component failure the unlikely cause of most
problems. The most common causes of problems are
programming errors and interface connections.
Use the following guidelines when troubleshooting a
GETC on site:
1. Verify the operation of front panel LEDs. This
can be done by performing the Operational
Checkout and verifying the LED indications.
GETCs using 349A9607 Group 4 software may
also indicate the specific cause of the failure, refer
to Failure Mode.
2. Verify that all cables are properly connected and
secure.
3. Verify the GETC’s personality is properly
programmed for the specific application. Refer to
TQ-3357, PC Programmer and SRN1060 (SRN
1024 if using 19A705595G8 software).
4. Verify the Turbo Board is properly configured if
applicable. Refer to LBI-38822 and SRN 1062.
5. If you suspect that the GETC has failed, replace
the it with a known good unit properly configured
for this application. Recheck all software and
personality parameters and checkout the GETC’s
operation. If the GETC functions properly, repair
or replace the malfunctioning GETC according to
the instructions in LBI-38894.
panel LEDs. Prior to group 4 software, a failure is
indicated by incorrect LEDs, but the GETC did not indicate
the root cause. The failure modes listed in Table 14
describe the LED displays and their corresponding failure
mode interpretation.
In all 3 failure modes, the channel is completely taken
out of service. This allows the System Manager in Fully
Trunked systems to display a channel failure. In Trunked
Failsoft, the channel is removed from service to avoid using
the bad channel.
CHANNEL ACTIVITY LOGGER
Another diagnostic feature introduced with the
349A9607 Group 4 software is the Channel Activity
Logger. This feature allows the GETC to supply
information about what it sees from its inputs: the RF
receiver, phone line receiver, station interface I/O.
Additionally, the GETC can supply internal event
information about what the GETC is doing. For example,
if the GETC tries to train its Rockwell modem, it will print
a message “MODEM TRAINING STARTED,” and when
the modem becomes trained, it will print “MODEM
TRAINING COMPLETED.” In General, the information
supplied by the Channel Activity Logger is EDACS specific
and in some cases may need technical assistance for
interpretation. For detailed instructions on using the
Channel Activity Logger, refer to SRN1060 and PC
Programmer TQ-3357 V4.03 (or later).
IN CASE OF DIFFICULTY
FAILURE MODE
With the introduction of 349A9607 Group 4 software,
the GETC is able to indicate a specific failure via the front
