SYSTEM DESCRIPTION AND INSTALLATION MANUAL HS--700 High Speed Data System SECTION 1 SYSTEM DESCRIPTION AND OPERATION 1. Overview A. General (1) The HS--700 high speed data (HSD) system is designed to form part of the MCS--7000 Aero H/H+ satellite communication (SATCOM) system. The MCS--7000 multi--channel SATCOM (MCS) system includes a SD--700 satellite data unit (SDU), HP--600 high power amplifier (HPA), and Aero--H/H+ high gain antenna (HGA). The HS--700 high speed data unit (HSU) provides an additional dedicated 64 kbps integrated services digital network (ISDN) or mobile packet data service (MPDS) channel that can be operated simultaneously with the MCS--7000 SATCOM system. (2) Figure 1-1 shows how the HSU interconnects to the MCS--7000 SATCOM system. The HSU is operated as a slave to the MCS system in cooperative mode. The SD--700 SDU controls the slave HSU through a high speed ARINC 429 bus and a disable discrete. (3) The HSU is a terminal for data, fax, and voice communications through the Inmarsat global area network (GAN). It provides the services of this network to the user. The user can access these services through the user interfaces of the terminal. (4) The L--band radio frequency (RF) transmit outputs of the HSU and the SDU are combined with an RF combiner. The output of the RF combiner drives a common 40 W HPA, the diplexer portion of the diplexer/low noise amplifier (DLNA), and nominal 12 dB gain antenna. The SDU manages the satellite selection and steers the HGA. (5) The L--band RF signals received from the satellite by the HGA and amplified by the low noise amplifier in the DLNA are divided in two by the RF splitter. One signal set is connected to and processed by the SDU. The other signal set is connected to and processed by the HSU. In this way, full duplex communication is achieved for all parts of the system (MCS--7000 and HS--700). (6) The MCS--7000 SDU and HPA require only operational software modifications to properly operate with the HS--700. 23--20--33 Page 1--1 30 Aug 2002 Use or disclosure of information on this page is subject to the restrictions in the proprietary notice of this document.

SYSTEM DESCRIPTION AND INSTALLATION MANUAL HS--700 High Speed Data System (2) When used within the spot beams, the Aero--H+ service requires less power so that call charges are reduced. (3) All Honeywell/Thales aeronautical equipment complies with the International Civil Aviation Organization (ICAO) Agency of the UN requirements for aeronautical safety services. The equipment can be used for communication, navigation, and surveillance/air traffic management (CNS/ATM). C. HSD Services (1) The HS--700 HSD system provides two modes of communication: circuit--mode and packet--mode. In these modes, there are five services provided as follows: • ISDN speech, typically used for ISDN telephones and Public Switched Telephone Network (PSTN) telephones connected with a terminal adapter (TA). • 3.1 kHz audio, typically used for analog data modems, group 3 fax machines, and secure telephone unit (STU) terminals connected through a TA. • 56 kbps unrestricted digital information (UDI) which is provided for compatibility with equipment requiring this service. • 64 kbps UDI, typically used for video terminals, group 4 fax machines, data communication, and secure telephone equipment (STE) terminals. • MPDS, which is used for internet access and access to corporate local area networks (LAN) through the virtual private network (VPN) service. (2) The first four services are circuit--mode services and MPDS is a packet--mode service. D. User Interfaces (1) The services of the HS--700 HSD system can be accessed through three interfaces: • ISDN NT1 (European S/T Interface) • EIA/TIA--232 Asynchronous Serial Port • 10BASE--T Ethernet Port. (2) The ISDN network termination 1 (NT1) interface is the access point for all circuit--mode services. This interface is physically located on the ARINC--404 connector on the rear of the HSU. Except for the physical design of the connector, this interface is ISDN compliant. The HS--700 is configured as NT1 for direct connection to the user’s terminal equipment 1 (TE1) interface, or for connection to terminal equipement 2 (TE2) through an external terminal adapter (TA). (3) The HS--700 includes an internal 100 ohm termination resistor for the ISDN interface to support cable lengths longer than three meters. (4) The ISDN interface can supply power to up to four ISDN devices, but supports up to eight devices if at least four of them have their own power supply. During primary power interruptions of up to 200 ms duration, the HS--700 is capable of maintaining hold--up with no more than one ISDN device being powered by the HS--700. For example, if more than one such phone is connected and an incoming call is received during a 200 ms power interrupt, the HS--700 may reset rather than hold--up over the power interruption. 23--20--33 Page 1--3 30 Aug 2002 Use or disclosure of information on this page is subject to the restrictions in the proprietary notice of this document. SYSTEM DESCRIPTION AND INSTALLATION MANUAL HS--700 High Speed Data System (5) The EIA/TIA--232 asynchronous serial port interface is the primary access point for MPDS. The port provides a standard modem interface with a Hayes compatible AT style command set. For the data communication, the port operates in the point to point protocol (PPP) mode. The HS--700 is configured as data circuit--terminating equipment (DCE), using hardware flow control (RTS/CTS) and operating at 115.2 kbps. (6) The 10BASE--T Ethernet port is an alternate access point for MPDS. The interface implements a standard 10BASE--T Ethernet port, except for the connector. MPDS is accessed using the point to point protocol over Ethernet (PPPoE). Only one of the two MPDS interfaces (10BASE--T or EIA/TIA--232--E) can be used at a time. The port to be enabled is selected during the configuration of the HSU. The MPDS interface configuration settings are stored in the configuration data module (CDM). The HS--700 is configured as an Ethernet hub (DCE). E. Service Routing (1) Table 1-2 illustrates the routing or mapping of calls of a certain service to the corresponding interface in the HS--700 system. Table 1-2. Service/Interface Service Routing ISDN Ethernet EIA/TIA--232 ISDN Speech Yes No No 3.1 kHz Audio Yes No No 64 kbps UDI Yes No (Note) No (Note) 56 kbps UDI Yes No (Note) No (Note) MPDS No Yes Yes NOTE: Hardware for these combinations are implemented but no software is implemented in the initial version of the HS--700 system. 23--20--33 Page 1--4 30 Aug 2002 Use or disclosure of information on this page is subject to the restrictions in the proprietary notice of this document. SYSTEM DESCRIPTION AND INSTALLATION MANUAL HS--700 High Speed Data System F. Control and Status Interfaces (1) The control interfaces include the following: • CMT interfaces • ARINC 429 control interfaces • HSU disable control interface • Discrete outputs. (2) The HSU has two CMT interfaces, one on the front panel and one on the ARINC 404 connector at the rear panel. The rear panel interface makes it possible to connect to the SDU and have the SDU access the HSU’s commissioning and maintenance terminal (CMT) interface. The front panel interface provides an interface to a personal computer (PC) terminal for configuration and maintenance purposes. The CMT interfaces are used for configuration control, SW downloads, and debug. (3) The debug shell provides access to a series of commands provided for debugging purposes. The commands are organized in shells. The active shell can be read from the command prompt. (4) The SDU controls the HSU via the ARINC 429 Interface. The HSU operates as a slave to the SDU in cooperative mode. Three levels of communication are implemented on the ARINC 429 control interface as follows: • Solo words used for block transfers and solo words, for example, high priority and timing--critical messages. • Periodic words, which are words transmitted at a periodic rate. • SDU/HSU message transfer, which is a high level message transfer by Williamsburg protocol. (5) The Williamsburg protocol provides detection of errors and retransmissions of failed packets. The protocol also provides the transmission of data packets spanning more than one ARINC word. (6) A discrete input is provided for the SDU to disable the HSU. The HSU disable signal inhibits the transmitter output and keeps the HSU reset as long as it is activated. When released, the HSU performs a normal power--on self test (POST) procedure. (7) The HS--700 is supplied with three discrete outputs. One of the outputs is a spare for future use (not defined yet). The second is an HSD service availability indicator (ISDN or MPDS). The third is used to indicate failures in the HSU (from built--in test equipment [BITE], person--activated self--test [PAST] and POST). 23--20--33 Page 1--5 30 Aug 2002 Use or disclosure of information on this page is subject to the restrictions in the proprietary notice of this document. SYSTEM DESCRIPTION AND INSTALLATION MANUAL HS--700 High Speed Data System G. CDM (1) The HSU is supplied with a CDM, which is plugged into the rear panel of the HSU. The CDM stores all installation and user specific data and is designed to remain with the aircraft. This allows easy replacement of the HSU, without the need for a reconfiguration of the CDM. The CDM stores the following parameters: • ISN Number • Forward and Return ID • CDM Model Number • CDM Serial Number • CDM Data Type Version • Allowed Land Earth Station (LES) • Preferred LES • Default LES • Initial Equivalent Isotropic Radiated Power (EIRP) (e.g. 22.5 to 25.0 dBW) • Minimum Initial EIRP (e.g. 22.5 dBW) • Minimum Call EIRP (e.g. 17 dBW) • MPDS Initial EIRP (e.g. 22.5 dBW) • MPDS Interface Selection (Ethernet or EIA/TIA--232) • Receive (RX) Cable Loss • Transmit (TX) Cable Loss • Automatic Test Equipment (ATE) Access Levels. (2) All parameter values and settings except for the protected and non--changeable values can be read out from the CMT interfaces. This makes it possible to store all the information on a floppy disk. (3) Each CDM is configured from the manufacturer with ISN numbers, IDs, and default values for all of the configuration parameters. If a defective CDM is replaced on an aircraft, all of the configuration parameters must be reentered into the new CDM through the CMT. Two CDMs cannot have the same ISN and IDs. H. Boot Loader (1) All software in the HSU (except for the boot loader) can be downloaded through the CMT interfaces without any hardware modifications. New software is loaded using the X--modem protocol with 1024 byte packets and cyclic redundancy check (CRC) on all packets. The transfer rate is 9.6 kbps (fixed) except for software upload on the CMT1 (front panel) interface, which is 115.2 kbps. During download, the HSU verifies the software for compatibility and errors (CRC). A command in the debug shell lists the loaded file with CRC and version information. 23--20--33 Page 1--6 30 Aug 2002 Use or disclosure of information on this page is subject to the restrictions in the proprietary notice of this document. SYSTEM DESCRIPTION AND INSTALLATION MANUAL HS--700 High Speed Data System I. BITE (1) General (a) The HSU has two types of BITE: continuous monitoring (CM) and PAST/POST. If a BITE error occurs, the BITE error code number is reported to the SDU and the fail/pass light emitting diode (LED) illuminates red. (b) The CDM has no BITE functions performed by itself. The HSU performs the BITE tests on the CDM by checking CRC, etc. If a BITE error occurs in the CDM, the BITE error code number is reported to the SDU and the fail/pass LED on the HSU illuminates red. (2) POST (a) The HSU can report some errors during POST, but these errors do not prevent the SDU from operating properly. The SDU and HSU take appropriate actions on the detected BITE errors. Some of the more drastic actions from the SDU could be to turn the HSU RF off and reset and keep the HSU reset. (3) PAST (a) The PAST can be activated either through the SDU control interface or the reset button on the front panel of the HSU. The PAST performs the same tests as the POST. (4) CM (a) Some of the hardware in the HSU is under continuous supervision by the BITE software or by dedicated BITE monitoring hardware (for burst duration monitoring). If any errors are detected either by software or hardware, they are reported to the SDU and appropriate actions are taken. (5) Performed Tests (a) Each error code is categorized into either an error or warning. Errors are errors that prevent the full use of all the HSU functionalities. Warnings are errors that do not prevent the use of the HSU but require the HSU to be sent for repair. The tests include: • Digital hardware integrity tests • Software integrity tests • RF hardware monitoring. J. Cable Loss (1) The RF cable loss specifications for the RX and TX coax cables are per ARINC 741. ARINC 741 specifies an allowable input power level to the HPA of --12 to --2 dBm, given a variation in SDU to HPA cable loss of 19 to 25 dB (including a possible external combiner for multiple antenna configurations). For each installation, the specific RX and TX cable loss must be entered into the CDM through the CMT interface for the HSU to be able to compensate its RX and TX gain accordingly. 23--20--33 Page 1--7 30 Aug 2002 Use or disclosure of information on this page is subject to the restrictions in the proprietary notice of this document. SYSTEM DESCRIPTION AND INSTALLATION MANUAL HS--700 High Speed Data System K. Power Management (1) General (a) The HPA is shared between the SDU and the HSU. The HSU has to cooperate with the SDU regarding the use of the shared HPA. (2) Power Allocation (a) The output power of the HPA is a limited resource. The SDU is responsible for the management of this resource. The HSU must request that the SDU allocate power before it can start a transmission. Depending on the channel mode (Table 1-3), the HSU asks the SDU to allocate the required amount of power before using the channel. For burst mode channels such as MPDS, a fixed power allocation is assumed. If sufficient power is granted, the SDU informs the HSU what backoff from 12 dBm will generate the requested power, and then the HSU can initiate the transmission. The HSU indicates to the SDU what is the lowest amount of power that the SDU can allocate to initiate a call before the call setup is rejected. (b) In the single carrier per channel (SCPC) and MPDS modes, the HSU may operate in either nominal power mode (25 dBW) or economy mode (less than 25 dBW) depending on a setting in the CDM. When the power control protocol of the LES reduces or increases the EIRP of the HSU, the HSU gives the SDU the new EIRP level. The HSU also waits for the SDU to indicate what power is available and what the HSU backoff level should be. If the HSU receives a lower power allocation than it requested, it operates the channel until the channel naturally terminates or the power is less than the Inmarsat minimum requirement of 17 dBW. (c) An SDU owner requirements table (ORT) item governs the minimum power that the SDU will allocate for the HS--700, even when the HS--700 indicates a lower current power requirement due to ongoing dynamic power control commands from the ground station. This allows for more stability of both Aero--H/H+ and HSD calls, for example, fewer incidents of calls being terminated (shortly after being established) due to changing power requirements.

SYSTEM DESCRIPTION AND INSTALLATION MANUAL HS--700 High Speed Data System (3) Power Adjustment (a) By design, the shared HPA assumes a constant input level. Subsequently, the HSU has to adjust its carrier level when an event causes the SDU to change its carrier level. (b) The SDU is responsible for informing the HSU when adjustment is required and what the new backoff will be relative to the initial power. The HSU applies the new backoff immediately upon reception of the SDU message. (4) Power Preemption (a) There are conditions when the SDU needs to ask the HSU to release the power that has been reserved for its use. For example, a cockpit/important cabin call needs to be made and there is not enough power available for it without sacrificing the HSU power, the antenna gain has fallen too low to support any channel types, etc. (b) The preempt type indicates power is no longer available and all the HSU can do is terminate any ongoing transmission and inform any user that the service is no longer available. When a preemption has taken place and the SDU is still logged--on (e.g still steering the antenna), the HSU asks for power to be reserved every 10 seconds. (c) An SDU ORT item governs how the SDU will manage preemption of HSD calls when Aero--H/H+ calls (new or ongoing) require power that would otherwise be used by HSD calls. This item has no effect on the priority preemption scheme, whereby higher priority safety--service Aero--H/H+ calls preempt lower--priority calls (including HSD) as required. This ORT item has separate settings for ISDN and for MPDS. These settings govern whether or not the respective HSD service can be preempted, as required, in favor of non--safety (public correspondence) low--priority Aero--H/H+ calls (voice, fax, or PC modem). This item can thus be used to favor such Aero--H/H+ calls over HSD, or vice--versa. For example, the SDu can be set to allow Aero--H/H+ calls to preempt (as necessary) MPDS HSD, but not ISDN HSD, assuming that active phone calls are more important than the always--on but possibly idle MPDS, and that active ISDN HSD is more important than voice calls. 23--20--33 Page 1--9 30 Aug 2002 Use or disclosure of information on this page is subject to the restrictions in the proprietary notice of this document.

General (1) This section contains information on how and where to mount the HSU, CDM, combiner, and splitter. Figure 2-1 shows the HSU dimensions. Figure 2-2 shows mounting tray dimensions. Figure 2-3 shows the physical attributes of the CDM. Figure 2-4 shows the dimensions and mounting hole dimensions of the RF splitter/combiner. B. Equipment and Materials (1) See the applicable outline and installation diagram in this section for mounting information. 2. Mechanical Installation Design A. HS--700 HSU Provisions (1) Mechanical installation data for the HS--700 HSU is shown in Figure 2-1. The HSU is mounted in an ARINC 404A 1/4 ATR short , 2MCU chassis with one hold--down hook. It can be installed inside the pressurized area, or outside (within the limits of DO--160D specifications). It is important that the HSU is installed in a location where its operational temperature specifications are met. The HSU is approved for installation on jet engine aircraft, but not turboprops or helicopters. No special cooling is required, but the airflow must not be blocked. (2) The location of the mounting tray should allow the interface cabling to other units to be as short as possible. The location must give protection against rain, condensation, solvents, and hydraulic fluid. The mounting tray must be electrically bonded to the aircraft frame by a low resistance path of less than 0.1 ohm. Mechanical installation data for the mounting tray is shown in Figure 2-2. B. CDM Provisions (1) Mechanical installation data for the CDM is shown in Figure 2-3. The CDM is designed for mounting into the slot in the HSU rear panel and acts as an integrated part of the HSU. The CDM has the same installation requirements as the HSU. (2) A stud on the CDM can be used to attach a tether between the CDM and the mounting tray to make sure that the CDM stays with the aircraft in case the HSU must be replaced. C. RF Splitter/Combiner Provisions (1) Mechanical installation data for the splitter/combiner is shown in Figure 2-4. 23--20--33 Page 2--1 30 Aug 2002 Use or disclosure of information on this page is subject to the restrictions in the proprietary notice of this document.

SYSTEM DESCRIPTION AND INSTALLATION MANUAL HS--700 High Speed Data System SECTION 3 ELECTRICAL INSTALLATION 1. Overview A. General (1) This section gives electrical installation procedures, power distribution, and interconnect information for the HSU, combiner, and splitter. (2) Procedures for proper shield, power, and signal grounding are also provided in this section. In addition, procedures for the various buses are included. B. Equipment and Materials (1) See leading particulars table for a list of mating connectors required to do the electrical installation. 2. Electrical Installation Procedure A. General (1) The information necessary to provide the electrical interconnects is contained in the following paragraphs. B. Power Requirements (1) The aircraft dc power supply must be 28 V dc (nominal). The normal minimum and maximum voltages permitted are 20.5 and 32.2 V dc respectively. (2) Power supply to the HSU -- The voltage level of the power supplied to the HSU is important in this installation. The potential is the difference between the power pins and power ground pins at the line replaceable unit (LRU). Excessive voltage drops in the power wire(s) and power ground wire(s) cause one or more of the following conditions: • The LRU draws additional current from the aircraft supply system. • The voltage drop can become large enough that the LRU oscillates on and off at low line. This oscillation can damage the LRU. (3) The HSU is supplied from the 28 V dc aircraft power system through a separate circuit breaker. It is essential to keep the impedance of the power supply cables below the limits specified in Table 1-6. The HSU also provides the power supply voltages to the CDM. (4) The recommended maximum total combined voltage drop (voltage drop of the power wire[s] plus voltage drop of the power ground wire[s]) low line input is 1.0 V. Voltage drop is a function of current and resistance (resistance in this case is a function of wire gauge and wire length). See Figure 3-1 for determining proper wire gauge for a round trip length of LRU power and power ground wires. 23--20--33 Page 3--1 30 Aug 2002 Use or disclosure of information on this page is subject to the restrictions in the proprietary notice of this document. SYSTEM DESCRIPTION AND INSTALLATION MANUAL HS--700 High Speed Data System Figure 3-1. Electric Cable Chart C. Ground Requirements (1) General (a) Proper grounding is a key factor in ensuring proper system operation under normal conditions, high intensity radiated electromagnetic frequencies (HIRF), and lightning environments. You must obey this section to satisfy these requirements. NOTE: HIRF and lightning requirements dictate that the shielded wires meet the requirements of paragraph 2.C.(3). Installation of this system into aircraft manufactured prior to the FAA requirements adheres to these practices whenever feasible. (2) Chassis Grounding (a) All rack mount/remote mount units are electrically bonded to the airframe. This is done by making sure the mating surfaces between the LRU mounting tray (or LRU mounting feet if a tray is not used) provide a low impedance (< 0.1 Ω) electrical path. 23--20--33 Page 3--2 30 Aug 2002 Use or disclosure of information on this page is subject to the restrictions in the proprietary notice of this document. SYSTEM DESCRIPTION AND INSTALLATION MANUAL HS--700 High Speed Data System (b) The mating surfaces must be free of all paint and other non--conductive elements and are burnished to ensure a good bond. If the aircraft mating surface is not conductive, a bonding strap of a least 1/4--inch wide (preferably 1/2--inch wide) tin coated copper braid can be used between the LRU mounting tray (or LRU itself if a tray is not used) and the nearest airframe grounding point. (3) Shield Grounds (a) The shield wires in the HSU have the shield grounded at both ends. This is called multi--point grounding and is specified to minimize the adverse effects of HIRF and lightning. (b) The shield must not be connected to any LRU or bulkhead connector pin. (c) Examples of multi--point shield grounding methods are shown in Figure 3-2 and Figure 3-3. The shield grounding method for rack mount units is detailed in Figure 3-4. This is the preferred shield grounding method for the HSU rack mount unit. Figure 3-2.

SYSTEM DESCRIPTION AND INSTALLATION MANUAL HS--700 High Speed Data System Figure 3-4. Shield Grounding Example for Rack Mount Connectors (4) Power/Signal Grounds (a) The length of exposed unshielded cable and the length of the drain leads is critical for proper operation and EMC compliance. Figure 3-5 shows the proper aircraft grounding method. It is critical that the ground pigtails be individually connected to the tag ring(s). If the are daisy--chained, there will be EMC compliance issues. Coaxial cables must have a continuous shield from the cable into the tray connector. Do not put pigtails coaxial cables. NOTE: It is very important this grounding technique be adhered to. Do not tie the various ground wires to multiple aircraft frame points and depend on the aircraft structure to supply a low impedance path for the individual grounds. Only chassis grounds and shield grounds are grounded at multiple points in the aircraft. 23--20--33 Page 3--4 30 Aug 2002 Use or disclosure of information on this page is subject to the restrictions in the proprietary notice of this document. SYSTEM DESCRIPTION AND INSTALLATION MANUAL HS--700 High Speed Data System Figure 3-5. Aircraft Grounding (b) Because signal grounds are low currents, multiple signal grounds can be connected to remote aircraft terminal blocks other than the central grounding blocks as long as these remote terminal blocks are isolated from ground. The various remote signal ground blocks must all be grounded only at the aircraft central grounding point. If 10 signal grounds are connected to a remote terminal block, a minimum of one grounding wire must be run from this terminal block to the aircraft central grounding point. 23--20--33 Page 3--5 30 Aug 2002 Use or disclosure of information on this page is subject to the restrictions in the proprietary notice of this document.

HSU Interface Block Diagram (2) HSU X1 Connector (a) The HSU front panel X1 connector is an interface to a PC for maintenance purposes. The X1 connector is a 9--pole female sub--D filter connector. The HSU X1 connector layout is shown in Figure 3-7. Table 3-1 gives the pin assignments of the X1 connector. (b) The HSU has two CMT interfaces, one on the X1 connector (CMT1) and one on the X2 connector (CMT2). Both interfaces support EIA/TIA--232--E standard and can also be used as a printer interface. Only the CMT1 on the X1 connector can be used for software uploading. The interfaces are configured as DCE on the HSU. (c) The CMT1 interface (pins 2, 3, and 5) has a Baud rate of 9,600 bps or 115.2 kbps for software uploading. There are eight data bits and one stop bit with no parity. (d) The HSU X1 connector contains an input pin (pin 4) to disable the X2 rear connector CMT2 interface. If the rear connector CMT2 interface is connected to a terminal, it is diabled when using the front connector CMT1 since both CMTs share the same internal serial I/O port. (e) The rear connector CMT2 interface is disabled by connecting X1 connector pin 4 to --12 V dc. This is done by mounting a jumper from pin 4 to pin 6 in the serial cable plug. If a fully populated RS--232 serial cable is used, no jumper is needed. 23--20--33 Page 3--6 30 Aug 2002 Use or disclosure of information on this page is subject to the restrictions in the proprietary notice of this document.
