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 (LES), Ground Earth Stations (GES), Aircraft Earth Stations (AES), and Mobile Earth Stations (MES).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 the 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).I-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).DRAFT as of 4 Mar 2016

(a) Setting the Call PriorityYou can set the priority for an air-to-ground four-wire Classic call before making the call.This priority setting allows for preemption of existing lower priority Aero H+ calls if insufficient satellite resources exist to establish an independent call, and for preemption of calls and services within the cabin.If the four-wire Classic call is the same priority as an existing call, the established call will be retained and the new call will be queued.Cockpit calls over SBB are Public priority calls. You can not change the priority.All calls made from the interfaces other than the cockpit four-wire phones or ACARS CMU are Public priority calls.(b) Receiving a Priority CallIf a cockpit call is in progress and a higher priority ground-to-air call is received, the higher priority incoming call will preempt the existing call. The preemption is automatic, and the caller in the cockpit has no option to choose between calls.(3) Saving Telephone Numbers in the Telephone DirectoryYou can save telephone numbers to the TCP’s telephone directory to use later, and you can dial telephone numbers from the telephone directory.NOTE: Saving telephone numbers in the directory may be inhibited by ORT options.To save telephone numbers to the telephone directory:DRAFT as of 4 Mar 2016

Owners Requirements Table (ORT)A. ORT OverviewThe A781-500 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 a secure ORT file, contact RC 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. To modify the user ORT parameters, use the ORT Application. To obtain the ORT Application, contact RC Product Support.For more information see the following guides:• Publication No. D201511000062, A781-500 User ORT User Guide• Publication No. D201511000064, A781-500 Secure ORT User Guide• Publication No. D201511000061, A781-500 ORT Application Install Manual.6. Passive Intermodulation (PIM) TestThis section describes the passive intermodulation test. You must execute the PIM test after installation if the A781-500 SDU operates in SBB mode.A. OverviewTo meet Inmarsat requirements for SBB operation, the A781-500 SDU can test for passive intermodulation effects. The PIM test verifies that the transmit signal from the A781-500 SDU does not degrade or interfere with the receive signals as a result of PIM.A781-500 SDU can only perform the PIM test when the aircraft is on the ground.When the A781-500 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 A781-500 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:• The A781-500 SDU must have successfully logged on to a satellite that is visible at the test location within the last 168 hours (7 days).DRAFT as of 4 Mar 2016

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. Refer to "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—pass level is adjustable in Secure ORT• 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.SAFE MODE Configuration error detected. Possible causes: • Strapping parity error. • FMPA messages when standalone mode strapped. • Secure ORT parameters are not available.SATCOM cannot operate until configuration fault is eliminated (see description for possible causes). Once the fault is eliminated, wait for the status to change to READY and run PIMBIT.NOT ALLOWED IN AIR Air/Ground status indicates in air.

ORTThe A781-500 system may not function properly if the ORT parameters do not match the installed system.(1) ORT Use and StorageThe ARINC 781 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 RC Product Support.The load procedure loads an ORT file 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.(2) Checking the ORTYou can check the content of the ORT file through the maintenance port menus. "SDU Maintenance Port Utility" on page 4-2 provides information about accessing the maintenance port menus.NOTE: The ORT includes many parameters that affect internal operations. These parameters are not meaningful for technicians troubleshooting the satellite communication system.To check the ORT:(a) In the maintenance port menus, navigate to menu 3.(b) To list the ORT, press H.The list of ORT parameters appears. The list is about eight pages long.Some ORT parameters displayed are system defaults that cannot be modified through the Secure and User ORT files.(c) Compare the ORT parameters to the system installed in the aircraft.I. Contact Product SupportWhen the troubleshooting procedures do not find a fault and the A781-500 system does not function properly, contact RC Product Support.RC Product Support may ask you to capture and send them system specific logs and reports.To access logs:(1) In the maintenance port menus, navigate to Menu 3.(2) Turn on the text capture feature of the terminal emulator on your computer.In HyperTerminal, click Transfer, and then click Capture Text.DRAFT as of 4 Mar 2016
