SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUALARINC 781-200 SDU and SCM23-15-30 1-1DATE TBDSYSTEM DESCRIPTIONThis section includes basic information about the A781-200 system, including the following sections: • Inmarsat System Overview • Equipment Overview • Equipment Specifications • System Interfaces • User Interfaces • Software Description1. Inmarsat System OverviewThis section provides an overview of the Inmarsat satellite communications system and networks.Satellite communication systems provide users with long-range voice and data communication by accessing global satellite and ground communications networks. Satellite communication systems include global satellite networks, Land Earth Stations (LESs), Ground Earth Stations (GESs), Aircraft Earth Stations (AESs), and Mobile Earth Stations (MESs).The LES/GES is the part of the satellite communication system that is on the ground. These numerous, international stations are responsible for routing voice and data calls from the MES/AES to their destinations around the world. The MES/AES is the part of the satellite communication system that is on the aircraft. GES and AES are the terms associated with Aero-H+ services. LES and MES are terms associated with other satellite communication services.Inmarsat is an international organization that operates and maintains multiple geostationary satellites and satellite networks (I-3 and I-4). For more information about I-3 and I-4 satellite beam coverage, refer to the Inmarsat website—www.inmarsat.com.I-3 satellites provide Inmarsat services for aviation (Aero H+ and Swift 64), shipping, and land-mobile users. The satellites connect to ground telecommunication systems through a network of GESs. Each I-3 satellite is located over an Ocean Region (OR)—the current OR names are: • Atlantic Ocean Region-East (AOR-E) • Atlantic Ocean Region-West (AOR-W) • Indian Ocean Region (IOR) • Pacific Ocean Region (POR)
SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUALARINC 781-200 SDU and SCM23-15-30 1-2DATE TBDI-4 satellites provide worldwide SwiftBroadband (SBB service). Each I-4 satellite has 19 wide spot beams, 228 narrow spot beams, and is capable of accommodating many separate, simultaneous SBB sessions. The SBB service and I-4 satellites support broadband applications. The current I-4 satellites are: • AMERICAS • EMEA (Europe, Middle East, and Africa) • APAC (Asia-Pacific)The satellite communication avionics (A781-200 system), in conjunction with an antenna subsystem, act as an AES/MES. The combined system provides users with a data and voice communications link to the satellite network and global telecommunications system. Figure 1-1 illustrates a simplified satellite communications system.Figure 1-1 Simplified Aeronautical Satellite Communications System2. Equipment OverviewThe A781-200 system, in combination with the antenna sub-system, provides Aeronautical Mobile Satellite Services (AMSS) by facilitating airborne satellite communications over the Inmarsat network, including the following services:
SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUALARINC 781-200 SDU and SCM23-15-30 1-3DATE TBD • Classic Aero-H+—Provides packet data services at 600 bps, 1200 bps, or 10500 bps over the PRT channel combination and half-rate circuit switched voice or data service over the C channel. • Swift 64—Provides packet switched Mobile Packet Data Service (MPDS) or 64kbps circuit-switched Unrestricted Digital Information (UDI). • SwiftBroadband (SBB)—Provides AMBE+2 voice (circuit-switched) and broadband packet switched services. The equipment can achieve aggregate rates of 432 kbps, but data rates may vary with network load and signal quality. The equipment can be configured for either single or dual SBB.The A781-200 system consists of the Satellite Data Unit (SDU) and the Satellite Data Unit Configuration Module (SCM).Figure 1-2 illustrates the A781-200 system.Figure 1-2 A781-200 Avionics SystemA. SDUThe SDU is the central communications processing and control unit and largely determines the functionality of the complete SATCOM system. It manages interfaces, routing and priorities, and call channel establishment and tear down. The SDU provides RF power amplification using an internal high power amplifier (HPA).The SDU is divided into several Shop Replaceable Units (SRUs) that are electrically connected via the backplane. Various SRUs are also connected using RF cables. B. SCMThe SCM is an external peripheral of the SDU and provides a dedicated interface to the SDU. It stores Secure and User ORTs (Owner Requirement Tables), a Swift 64 Forward ID and the keys to enable either single or dual SBB capability. The SCM can accommodate up to four Universal Subscriber Identity Modules (USIM) that store subscriber information for the SBB network.
SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUALARINC 781-200 SDU and SCM23-15-30 1-4DATE TBDBy storing configuration information independent of the SDU, the SCM facilitates efficient SDU replacement. A new SDU that replaces a faulty SDU does not require any configuration. All configuration information is obtained from the SCM.3.

ORT OverviewThe A781-200 system includes a secure and user ORT. Secure ORT files must be certified for the aircraft type on which the equipment is installed. Items in user ORT files can be modified by individual customers and may be customized to an individual aircraft.You can change secure ORT parameters only by uploading an ORT file. To obtain an ORT file, contact RCI Product Support.The ORT file is loaded on to the SCM using an ARINC 615A data loader. You can only load ORT data when the aircraft is on the ground and the data load discrete is asserted. When the SDU boots, it compares the ORT file in its memory to that in the SCM. If the ORT files do not match, the SDU loads the file from the SCM into its memory.Some user ORT parameters can be modified in the SDU ORT. You can reset the SDU ORT to the default values stored in the SCM in the maintenance menus.For more information see the following Guides: • MN-0000461, A781-200 User Ort User Guide • MN-0000462, A781-200 Secure ORT User Guide • MN-0000463, A781-200 ORT Application Install Manual6. Passive Intermodulation (PIM) TestThis section describes the passive intermodulation (PIM) test. You must execute the PIM test after installation if the A781-200 SDU operates in SwiftBroadband mode.A. OverviewTo meet Inmarsat requirements for SBB operation, the A781-200 SDU can test for passive intermodulation effects. The PIM test verifies that the transmit signal from the A781-200 SDU does not degrade or interfere with the receive signals as a result of PIM.A781-200 SDU can only perform the PIM test when the aircraft is on the ground.When the A781-200 SDU logs on to the SBB network, the network assigns the terminal two channels for PIM testing. These channels are not used by other terminals so that the A781-200 SDU can transmit the test frequencies without interfering with other satellite communication equipment or the Inmarsat satellite.B. PIM RequirementsIn order to successfully perform the PIM test, the aircraft and the satellite communication system must meet the following requirements:15 Power Return 0 V Table 3-3 SCM D-Type Connector Pin Assignment (Continued)Pin Number Description
SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUALARINC 781-200 SDU and SCM23-15-30 3-9DATE TBD • The A781-200 SDU must have successfully logged on to a satellite that is visible at the test location within the last 168 hours (7 days). • The aircraft has to be outside the hangar and far away from the hangars and towers in order to obtain good results. • The aircraft must be facing due north in the northern hemisphere, and due south in the southern hemisphere.C. PIM TestTo run the PIM test you must be in maintenance mode. You can only access the MCDU maintenance menus when the plane is on the ground and classic services are logged off.To start the PIM test: 1. In the MCDU CONFIG 1/4 menu, type the protection level code in the scratchpad, and press the button next PROT LEVEL CODE.NOTE: Contact RCI product support for the PROT level code.The SATCOM Maintenance Entry page appears. 2. To enter maintenance mode, press the button next to CONFIRM.The MAINTENANCE MENU appears. 3. To start the PIM test, press the button next to INTERMOD TEST.The PIM test starts. The test takes about five minutes.D. PIM Test Results(1) PIM Test Overall StatusAt the end of the PIM test, the A781-200 SDU displays the test results on the MCDU screen.
SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUALARINC 781-200 SDU and SCM23-15-30 3-10DATE TBDThe MCDU displays the overall PIM status and results for each direction. If the overall status is PASS, the SDU can continue to use SBB services.If the overall status is FAIL: • Check the cable connections of the antenna and the SDU. • Check the direction in which the test failed and verify that the antenna is not blocked in that direction—see "Directional PIM Test Results" on page 3-10.(2) Directional PIM Test ResultsThe SDU performs the PIM test with the antenna pointing in different directions and displays the results of the test in each direction. If the overall status of the PIM test is FAIL, you can check the specific directions in which the test failed.For each direction, the PIM test results provide: • Overall Status—pass or fail. • The direction coordinates. • The signal degradation—the maximum value to pass the test is 3 dB. • Possible interference—interference caused by environmental factors, not the SDU transmit frequencies. Interference indicates that the SDU received a signal in the receive band even when it wasn’t transmitting, therefore an external signal may be interfering with communication in that direction. • Signal and noise levels before and after the test—the SDU uses this information to check for possible interference.7.
