LBI-38988 INTRODUCTION

INTRODUCTION

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

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:

6 Rev. B

SOFTWARE FEATURES LBI-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

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. B 7

LBI-38988 SOFTWARE 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).

8 Rev. 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-38988 DESCRIPTION

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 GETC to the CEC/IMC Uplink GETC, adjust R2 for .77 Vrms (0 dBm) measured across J6-8 and J6-9 (TB10-1 and 2). For microwave links, adjust R2 for -10 dBm across J6-8 and J6-9.

6. Initialize the modem by pressing S4 (on the GETC Logic Board) to reset the Station GETC or cycle the GETC Shelf's operating power.

Jumper Installation

There are a few jumpers on the GETC Logic Board which must be re-configured for different applications. To properly configure the GETC jumpers, refer to jumper tables in SRN1060 and install or remove jumpers according the intended GETC application. The location of the jumpers may be found using the board layout diagram in Figure 4.
