LBI-38987The CEC/IMC controls and routes SCAT calls, allowingthe user to enjoy trunking features and the same trunked userinterface. The CEC/IMC must be configured with a site interface (MSZM3R) for the SCAT system.SCAT sites. However, use of the Centralized Telephone Interconnect System (CTIS or Jessica) is available in the multisite configuration.SCAT and DownlinkNOTEIn MASTR III systems, a cable (19D903880P10) isadded to allow easy access to the MIII Tx and RxAudio (J101). This cable is routed from from theMIII Interface Board J101 to the Downlink GETCTB10 pins 1, 2, 3, and 4.SCAT provides the control functions to implementEDACS access to the SCAT service area. The Downlink isessentially a message conduit providing a data communication path between the SCAT and the CEC/IMC.The Downlink’s modem data is synchronous at 9600baud using the full duplex operating mode. Data flows simultaneously in both directions as illustrated in Figure 3.Wide Area Digital OptionThe Wide Area Digital option (SXSF7A) enables the SCATstation to support Digital Voice communications. A hardwareoption (SXMD1D) provides an additional Rockwell Modemfor the SCAT GETC. This enables the SCAT GETC to sendand receive 9600 baud digital voice to the CEC/IMC using thefour wire audio line.NOTEThe SCAT software (344A3835) must be Group 2 orlater to support Digital Voice communications.OPERATIONAs a result of the SCAT station using only one channel,only one conversation can occur at any one time through theSCAT site. While the SCAT site is busy, every call request(mobile request or console request) is queued. The mobileradio generates the Call Hold Off queue tone and automatically places a call request upon completion of the first call.Only console request for the active group will be processedimmediately.SCAT operation can only be performed by radiosequipped to use a SCAT channel. SCAT only supports lateentry for group calls.The following radios are currently SCAT compatable:Radio TypeSoftware VersionAlpha 3, 344A(3705, 3703,4415, 4421, 4419, 4614)All Group 12PCS344A4272G1RANGR19A149268G21The SCAT channel and SCAT radios are designed tominimize the overloading of the inbound SCAT channel byprioritizing all calls. This allows the system to respond toemergency calls immediately upon availability of the channel.Except for interconnect calls, all group and individualcalls appear as transmission trunked calls to the radio and theCEC/IMC. This assures the mobile’s quick return to theControl Channel. Local interconnect is unavailable on2 TQ-3360 programming cable. Male DB-25 to female DB-9 adapter.

The Stand-alone SCAT requires asingle station GETC setup for SCAT operation. The NetworkSCAT requires a station GETC and downlink GETC. BothGETCs must be setup for SCAT operation. This section includes hardware installation instructions for both the Standalone and Network SCAT GETCs.SRN-1009- Software Release Notes for GETC SCAT SoftwareSRN-1010- Software Release Notes for Turbo Board SoftwareTQ-3357- GETC Shelf Programming ManualBSLDownlinkDataBlocksTxStand-alone SCAT GETCFigure 4 - SCAT to Downlink CommunicationEQUIPMENT REQUIREDSince these two protocols are different, the Downlinkconverts from one format to the other. In addition, both theSCAT and Downlink perform data error detection and correction, general control of timer and IO functions (DIPswitch, LED’s, UART’s, etc.), receive and transmit buffermanagement, message scheduling, and Turbo interfacing.The following equipment and software may be required toconfigure the GETC: IBM compatible PC with at least 640K memory,monitor, and keyboard. Hard disk is recommended; but, not required. Serial Port configured as either COM1 or COM2.Typically, a Stand-alone SCAT GETC is installed in the station cabinet just above the station’s radio assembly. The GETCis mounted within a slide out shelf measuring 1.75 inches high(one rack unit) by 19 inches wide.Installation or removal of the shelf sub-assemblies involvessliding the GETC shelf out of the cabinet and into the serviceposition. 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 II, IIe, or MASTRIII Application Assembly Diagrams for detailed information oninstalling the GETC Shelf.

LBI-38987Observe basic safety precautions to prevent injury or equipment damage.Network SCAT GETCThe Network SCAT option consists of a SCAT GETC, aDownlink GETC, a GETC interconnect cable and SCAT firmware for both GETCs. The interconnect cable provides theconnection from the SCAT GETC to the Downlink GETC using their Backup Serial Ports. Both the SCAT and DownlinkGETCs are configured with a Turbo Board for additional memory and processing capability.Data communication between the SCAT Downlink GETCand the CEC/IMC Uplink GETC is carried on a four-wire,data grade, type 3002 audio circuit. As shown in Figure 2, theSCAT Site is configured as a dedicated site connected to theCEC/IMC through the Uplink GETC. Therefore, the maximum number of SCAT channels on a multisite network isequal to the maximum number of sites allowed on theCEC/IMC.GETC Logic Board InstallationThis manual assumes that the Logic Boards in both GETCsare previously installed, setup for the default configuration(800 MHz EDACS), and fully operational. If for any reason aGETC Logic board is suspect, refer to Maintenance manualLBI-38894 for detailed instructions on removing, replacing,and testing the GETC Logic Board or the Regulator Board.Turbo Board InstallationThis manual assumes that both GETCs have the TurboBoard installed at the factory and they are fully functional. Ifthe Turbo Board is not installed or you encounter problemswhile installing the Turbo Board software, refer to LBI-38822and SRN-1010 for detailed instructions on removing, replacing, and testing the Turbo Board.Rockwell Modem InstallationA Rockwell Modem is always required in the DownlinkGETC. Use the following procedure to install the modem if itis not already installed:NOTEIf the SCAT station is setup to use the Wide Area Digital option, a Rockwell Modem must also be installed inthe SCAT GETC.
