SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
MCS--4200/7200 Multi--Channel SATCOM System
Taking an APBX handset off-hook results in the same decisions as specified
for the WH--10 handset. However, the SDU to APBX off--hook actions are
specified in Table 3-4, where the DTMF tone sequence ,
 (n is 0, 1, 2, or 4) sent to the APBX handset indicates the
SATCOM channel status:
• An outgoing call cannot be supported (n = 1, 2, or 4) or
• An outgoing call can be attempted (n = 0).
If the channel status indicates a call can be attempted, the SDU accepts any
command determined to be valid from an APBX interface, including the
on-hook DTMF tone. If the channel status indicates a call can not be
attempted, the APBX handset is expected to send the on-hook DTMF tone.
Otherwise, the SDU still accepts any command determined to be valid from
an APBX interface; though the checked B-party address transfer command
is guaranteed to produce a call setup failure. Subsequent to call setup
commands sent to the SDU, call setup progress, failure, and termination
DTMF tone sequences are sent to the APBX handset.
The SDU considers an off-hook channel to be in the on-hook state if no call
has been in progress on that channel and no DTMF signals have been
received for at least 120 seconds. A channel in the on-hook state must issue
another DTMF off-hook signal to enable the reentry into the off-hook state.
(b) Checked Credit Card Data Transfer Command
The *2284*c*ddd# command, if valid, loads the transferred three-digit value
into the SDU calling terminal ID buffer. This data is used in place of the
default 000 in the calling terminal field of the call information service address
initial signal unit (ISU) (S5) for any outgoing call setups on this channel until
the next APBX on-hook is received. The command is accepted only if the
modulo 10 sum of all the decimal digits in the command, including 2284, the
three-digit calling terminal ID, and the check digit c is zero.
(c) Checked B-Party Address Transfer Command
The *2262*cdddd....# command, if valid, initiates a call setup request to the
GES using the transferred digits dddd... as the B-party address and any
track 2 credit card data stored since the previous on-hook transition on this
channel. The command is only accepted if the modulo 10 sum of all decimal
digits in the command, including 2262 and the check digit c is zero. A valid
command causes the SDU to send the DTMF sequence ,
 to the APBX handset. An invalid command causes the SDU to
send the DTMF sequence ,  to the APBX handset.

SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
MCS--4200/7200 Multi--Channel SATCOM System
2. Cockpit Communications
A. General
(1) The SDU codecs support headset interfaces for cockpit use only. These interfaces
incorporate 600-ohm, 4-wire, off-hook/on-hook signaling and dialing through the
combination of a control and display unit (either SCDU or MCDU), and (at the user’s
option) PTT, mic-on, or place/end call switches. If used, when the PTT button is
pushed, the microphone audio signal is sent to the selected voice channel; activation
of one of the discretes is signalled to the SDU. Also, an off-hook signal can be sent to
the SDU through the SCDU. An audible chime and call lamps announce a
ground-to-air call.
(2) The cockpit headsets interface with the codecs in the SDU through an audio
management unit (AMU), which is also connected to other aircraft radios. The ACP
associated with the AMU can be capable of selecting either a single or dual voice
channels for the MCS system. When single-channel AMUs are installed, voice
channel 1 is wired to AMU No. 1 and voice channel 2 is wired to AMU No. 2. This
permits operation of two independent channels. When dual-channel AMUs are
installed, voice channels No. 1 and No. 2 are wired in parallel to each AMU, enabling
two voice channels to be shared by the cockpit users.
(3) Two functionally identical voice codec modules (VCM) are installed in the SDU and
designated Codec A and Codec B.
(4) Associated with the SATCOM channels are SCDU pages, call lamps, channel
selection switches, a chime, and a chime reset. The SDU hookswitch signaling can
be supplied:
• When the ACP SATCOM channel select switch is activated
• When a PTT switch is activated
• When signaling through the SCDU, where the SDU hookswitch signaling discrete
is inactive.
(5) Once off-hook, microphone audio is supplied to the selected SATCOM voice channel
and the appropriate signaling is exchanged for call lamp and chime reset.
Conversely, once on-hook, microphone audio is removed from the selected SATCOM
voice channel and the call lamp is turned off.
B. Headset Off-Hook Signaling
(1) The headset is capable of going off-hook (to connect the call and to acknowledge the
call signaling) if the cockpit voice call light output has transitioned for either the
flashing or steady light activation, at which time:
• If the latched ACP hookswitch signaling is strapped, the headset is considered
off-hook whenever the cockpit voice mic-on input is activated (connected to
ground).
• If the switched PTT hookswitch signaling is strapped, the headset is considered
off-hook whenever the cockpit voice mic-on input is activated for the first time after
the call light activation for an incoming call, or when the place/end call input is
activated to initiate an outgoing call.

(2) If ORT item xliii is enabled, the headset is capable of going off-hook when ANSWER
CALL is selected on the SATCOM main menu page (TESTING/FAULT ISOLATION)
after the call light activation and irrespective of hookswitch signaling.
C. Headset On-Hook Signaling
(1) If latched ACP hookswitch signaling is strapped, the headset is placed on-hook when
an open is present on the cockpit voice mic-on input. Regardless of the hookswitch
signaling, the cockpit voice place/end call 1 and 2 discrete inputs place the headset
interface on-hook for cockpit audio channels 1 and 2, respectively, when a call clear
event occurs. If ORT item xliii is enabled, the selection of END CALL or REJECT on
the SATCOM main menu page (TESTING/FAULT ISOLATION) places the headset
interface on-hook. Placing the headset on-hook results in normal call termination.
D. Voice Codec Module Audio Switching
(1) Headsets and analog connected phones interface to the SDU through the VCMs.
Using a switch internal to the modules, each VCM can be connected to one of the
cabin audio interfaces, or to one of the cockpit audio interfaces (or to both). Each
VCM can be switched between either of its audio interfaces as follows:
• Codec A can be used in conjunction with either cabin audio No. 1 (WH--10 or
APBX) or cockpit audio No. 1
• Codec B can be used in conjunction with either cabin audio No. 2 (WH--10 or
APBX) or cockpit audio No. 2.
E.
Voice Codec Module Sidetone
(1) Sidetone is supplied by each VCM. The sidetone level is adjustable for the cockpit
audio, and is set to off for cabin audio. The adjustment range for cockpit sidetone is
from 0 dB below the receive audio to off, with the default value set to 14.1 dB below
the receive audio level. This setting is stored in nonvolatile memory within the SDU.
F.
Voice Interface Module Stored Audio Messages
(1) The VIMs are capable of playing standard telephony supervisory lone signals, DTMF
tones, and voice messages to the headset and analog phone users. These pacifiers
are only sent to the analog interfaces:
• Headset
• WH--10 handsets
• APBX handsets.
(2) Stored audio messages are summarized in Table 3-5.

G. Voice Interface Module Dedication
(1) Each VIM has the property of dedication, which is different from the codec wiring.
This property is of value on aircraft that have both headset and cabin (analog and
digital) interface wiring, where contention for codec use can arise. Each VIM
dedication is set to cabin, headset, or automatic through ORT item vi.
(2) A VIM with its dedication set to automatic can be allocated to a headset call or a
cabin call, and is allocated on a first-come, first-served basis. A VIM can be
reallocated to a headset call of priority 1, 2, or 3 through the preemption mechanism.
A VIM with its dedication set to cabin is dedicated to its cabin (WH--10 or APBX)
interface.
(3) A VIM with its dedication set to headset is unusable by the cabin interface. A VIM can
be reallocated to a different headset call of priority 1, 2, or 3 through the preemption
mechanism. ORT item vii (Appendix C) specifies whether a modem and HPA power
should be reserved for a VIM dedicated to headset. This lets the pilot reserve one
channel for cockpit use only.

SECTION 4
MECHANICAL INSTALLATION
1. Overview
A. General
(1) This section contains information on how and where to mount each component of the
MCS system. For new installations, plan the installation in two stages. First,
determine the location of the LRUs in the aircraft. Next, determine the length of RF
and electrical interconnections for selected locations.
2. Equipment and Materials
A. General
(1) Refer to SYSTEM DESCRIPTION for mounting tray and mating connector
information. For all other components, refer to the applicable Outline and Installation
Diagram in this section.
(2) No additional special equipment or materials, other than those commonly used in the
shop, are required to install the units in existing trays and clamps, and to adjust the
system. Do not over tighten mounting screws. Where torque values are not given, it
is acceptable to finger tighten the mounting screws.
3. Mechanical Installation Design
A. LRU Mechanical Installation
(1) The SDU and HPA are installed in mounting racks (ARINC 600) typically in the
equipment bay of the aircraft. For a SATCOM installation, the primary installation
dependent parameter is the RF coax cable loss requirements identified in Table 4-1.
To make sure these requirements are met, some installations require the HPA(s) be
installed in close proximity to the antenna subsystem components. Refer to the
aircraft installation drawings for the location of the SATCOM equipment. For new
installations, refer to Table 4-1 to determine the location of the SATCOM equipment
to make sure the cable loss requirements are met.
(2) Mechanical installation data for the SDU, HPA, HSDU, and RFUIA are shown in
Figure 4-2 thru Figure 4--5.

CAUTION: BEFORE AN LRU IS INSTALLED, PULL THE CIRCUIT BREAKERS THAT
SUPPLY POWER TO THE LRU TO REMOVE POWER.
CAUTION: MOISTURE AND DIRT CAUSE DAMAGE TO LRUS.
CAUTION: LRU FAILURE RATES INCREASE WITH A RISE IN TEMPERATURE.
INSTALL THE LRUS WITH CLEARANCE. LET THE AIR FLOW ON TOP
AND BOTTOM OF LRUS TO PREVENT OVERHEATING.
CAUTION: MAKE SURE THAT THE LATEST ORT DATABASE SOFTWARE IS
INSTALLED IN THE SDU BEFORE PERFORMING SYSTEM
OPERATIONS.
NOTE: Honeywell/Thales recommends the MCS LRUs be installed so their
installation is level (zero degrees) to the horizontal plane of the aircraft.
Compliance with RTCA/DO--160D has been demonstrated with this
orientation.
NOTE: Ambient temperature at the LRU location must be less than 104 °F (40 °C)
during operation for best reliability.
B. Installation Dependent Considerations
(1) Refer to the SYSTEM DESCRIPTION section for the installation dependent
considerations for the SDU.
C. Owner Requirements Table (ORT) Uploading
(1) When the SDU is changed, the ORT needs to be uploaded before normal operation
can begin. Refer to the SYSTEM OPERATION section for the ORT upload
procedures.
D. Cable Loss Requirements
(1) The attenuation and voltage standing wave ratio (VSWR) of coaxial cable used in the
MCS system must meet the requirements specified in Table 4-1 to make sure the
system operates correctly. Figure 4-1 shows the specific cable attenuations for the
SATCOM equipment. All specified cable attenuations include connector losses, which
are assumed to be 0.1 dB each. Honeywell recommends each cable assembly be
sweep tested for loss and VSWR.

E.
Cooling Requirements
(1) The cooling requirements for the MCS avionics are specified in Table 4-2 as follows:
• Power dissipation is in Watts.
• Mass airflow is in pounds per hour.
• CF/M is cubic feet per minute at sea level and 104 °F (40 °C).
• Pressure drop is in inches of water.
(2) In most cases, a cooling system that meets the sea level requirements also meets
the cooling requirements at --67 °F (--55 °C) and 70,000 feet.

SECTION 5
ELECTRICAL INSTALLATION
1. Overview
A. General
(1) This section supplies electrical installation procedures, power distribution, and
interconnect diagrams for each component of the MCS system.
2. Equipment and Materials
A. General
(1) None.
3. Electrical Installation Procedure
A. Connector Layout and Contact Arrangement
(1) Each front panel connector of the SDU, HSU, and HPA complies with ARINC
characteristic 615, and is used to interface the LRU with an ARINC 615 portable data
loader for software uploads. Pin callouts are specified in Table 5-1. See the
MECHANICAL INSTALLATION section for specifics regarding connector part
numbers for the ARINC 615 connector for each LRU and the corresponding mating
connector.
(2) Table 5-2 lists the pin arrangements for the RJ--45 jack for the Ethernet Port 1. When
a user terminal is connected to this jack, the rear connectors are disconnected so
only the Ethernet Port 1 communications are available from this interface.
(3) The rear connectors of the SDU, HPA, RFUIA, and HSU comply with ARINC
characteristic 600 as specified in Table 5-3. The ARINC 600 connector layouts and
contact arrangement for the various connector plugs for each LRU of the MCS
system are shown in Figure 5-1 thru Figure 5-11.
(4) Table 5-4 and Table 5-5 list the contact arrangements for the top and middle inserts
for the SDU ARINC 600 connector. Table 5-6 lists the ICAO Block Strapping.

(2) The applicable configuration pins in the aircraft wiring must be connected to make the
MCS system functional. The SDU receives and sends 30 system configuration
discrete inputs through the configuration pins to properly match the avionics
equipment installed on the aircraft (see Figure 5-12 and Paragraph 4. to identify the
configuration pins).
(3) The SDU receives a 24-bit ICAO address that identifies the aircraft in which the SDU
is installed (Figure 5-12). Continuity is defined as a resistance of 10 ohms or less
between a configuration pin or address pin and the common. Continuity is broken
when the resistance between a configuration pin or address pin and common
measures 100k ohms or greater.

Interpretation
ICAO ADDRESS (AES ID) NOT AVAILABLE FROM CMU NO. 1 OR CMU NO. 2 OR
AES ID INPUT
ICAO ADDRESS (AES ID) IS AVAILABLE FROM CMU NO. 1 OR CMU NO. 2 OR AES
ID INPUT
(2) When wired to the zero state, the TP10A configuration pin indicates the ICAO 24--bit
aircraft address (AES ID) is available in the ARINC 429 label 275/276 format from
one or both of the SDU CMU input ports or ARINC 429 label 214/216 format from the
AES ID input port, and that one of those ARINC 429 sources of the address is used
with no specific preference for CMU 1, CMU 2, or the AES ID input. In this state, the
discrete inputs on SDU pins MP13C thru MP13K and MP14D thru MP14J are not
assumed to be wired and the SDU does not use the discretes, even if the ARINC 429
sources fail or remain inactive.
(3) In the zero state, the SDU monitors the CMU 1, CMU 2, and AES ID input buses until
a valid ICAO address is received. Bits 1 thru 16 of the AES ID are obtained from the
label 214/275 word and bits 17 thru 24 are obtained from the label 216/276 word.
The SDU only constructs a full 24-bit address from labels 214/275 and 216/276
words received from the same input port (e.g., label 214/275 from CMU 1 can not be
combined with label 216/276 from CMU 2 or label 216 from the AES ID input). The
address is only considered valid if it does not consist of all zeros or ones, and has
been received in ARINC 429 words with their sign--status matrix (SSM) indicating
normal operation.
(4) If address words containing either all zeros or ones are received, followed by address
words with a valid address (i.e., not all zeros or ones), the SDU verifies the receipt of
both labels 214/275 and 216/276 at least twice with the same address bits content in
each respective word before declaring the address valid. This is to preclude the SDU
from inadvertently and prematurely assuming the address is valid after only one of
the two labels has yielded a valid segment of the overall address, but the most
previously received copy of the other label has not yet been updated to its intended
code. The root problem is that the 24 correlated address bits are transmitted in two
separate asynchronous words that are not inherently correlated/paired. This
requirement is intended to effectively pair the label 214/275 and 216/276
transmissions.

(5) Once a valid ICAO address is received on any bus, the SDU ignores further data
received on any of the buses until the next POST/PAST. This requirement relieves
the SDU of having to deal with the possibility that the ICAO technical address might
change while the SDU is logged-on. The AES ID (ICAO address) is determined at
startup and cannot change until the next POST/PAST. The SDU does not log-on until
it has a valid AES ID. The SDU waits indefinitely to receive a valid address from an
available ARINC 429 source rather than giving up at the end of POST/PAST, since it
cannot proceed as an AES without the address. If the configuration pin indicates the
ARINC 429 source is available, the discretes are not wired. The SDU will not revert to
the discretes at the end of POST/PAST as the CMU may not yet be operational.
(6) If configuration pin TP10A is wired to the one state, then neither CMU input port nor
the AES ID input port is capable of supplying the AES ID in the ARINC 429 format
and the SDU reads the AES ID from the discrete inputs.
(7) With either the ARINC 429 or discrete inputs source, an AES ID of all zeros or all
ones (binary) is invalid (typically indicative of an unprogrammed address) which
constitutes a failure. The SDU does not attempt to log-on to a GES with an invalid
AES ID.

(2) When this configuration pin is wired to the zero state, the SDU operates its input and

to yield an odd number of strap bits set to the one state, including the parity pin itself.
(3) The parity pin is wired to yield odd parity over all 40 configuration pins (i.e., the parity
pin is programmed to the zero or one state to yield an odd number of configuration
pins wired to the one state, including itself. The SDU verifies the state of the parity
pin is correct when the configuration pins are read (typically once per power cycle just
after power-up). An invalid state of the parity pin is logged/reported/indicated; the
states of the other configuration pins are used as read despite the parity error.

source of IRS label 310, 311, 312, 314, 324, 325, and 361 information (although label
361, Inertial Altitude, is not required for SATCOM). The actual IRS (i.e., IRS No. 1,
IRS No. 2, or IRS No. 3) driving either SDU input is determined from the source
destination identifier (SDI) bits of the received ARINC words. The SDU only
logs/reports/indicates bus inactivity on either bus if the respective configuration pin
indicates that the bus is supposed to be connected to an ARINC 429 source. The
SDU can assume (for functional purposes) the presence of the IRS connections from

Note 1: Other configurations are possible and may be added at a later date. Note that ARINC Characteristic 761 Attachment 1-4B Table 1-3K (which is an extension of ARINC
Characteristic 741 Table 1-4K) defines configurations which include intermediate-gain antennas (IGAs). Those IGA configurations may also apply to ARINC Characteristic
741-compatible equipment; therefore, the IGA codes defined in ARINC Characteristic 761 should be considered as reserved for those definitions in this table as well. Any
changes to this table should be coordinated with ARINC Characteristic 761. Note that the configuration codes for “GNSS Frequency Check Required” and “GNSS
Frequency Check Not Required” are identical except for TP11J. Refer to ARINC 741 Part 2 Section 3.5.4.1.1 regarding the frequency check for GNSS interference
prevention.

MCS--4200/7200 Multi--Channel SATCOM System
(2) For functional purposes, the SDU assumes the HPA and antenna subsystem
configuration of its particular installation from states of these configuration pins.
However, configurations 100111 and 000111 are not supported. Both of the
nonsupported configurations involve the sharing of a single HPA between an LGA
and HGA, by using a high power relay (HPR). No control or BITE signal interfaces
are specified for the HPR, the MCS system does not accommodate these
configurations.
(3) The SDU commands the system, uses its resources, and logs/reports/indicates
failures in the HPAs and antenna subsystem based on the determined HPA and
antenna subsystem configuration. Inactivity on the SDU input buses from the HPA(s)
and ACU/BSU(s) and failures against the diplexer/LNA and HPR are
logged/reported/indicated if the respective LRU is specified to be connected
according to these pins. If these configuration pins are set to a nonsupported,
reserved for future, or reserved for Mfr state, the SDU logs/reports/indicates the
appropriate strap failure(s) and does not attempt any satellite communication
functions.

also indicates these signals are used to determine dual SATCOM operation as
specified in SYSTEM OPERATION. The SDU only logs/reports/indicates inactivity on
its input cross--talk bus from the second SDU when this pin is in the zero state. The
SDU can assume (for functional purposes) the presence of a second SDU from the

pins. The functionality of the cockpit call annunciation interface (pins MP8E and
MP8G for the call lights, and MP14B and MP14C for the chime) operate according to
the configuration pin connections selected. The selected state of pins TP13C and
TP13D applies to both air- and ground-initiated calls; it only applies to the call
annunciation phase (i.e., following connection acknowledgement by receipt of the
off-hook state as specified by the state of TP13K, a multistroke chime is silenced and
the call lamp remains on steady). The appropriate strap failure(s) is logged/indicated
if an undefined code is present. The SDU defaults to the steady lights and single
stroke chime state if an undefined code is present.
(3) The steady versus flashing light option applies to the call annunciation phase only.
The light remains on (steady) for the duration of the call after the acknowledgement
of the annunciation for either the steady or flashing light option.

(b) This configuration pin specifies the functionality of the SDU Cockpit Voice
Mic-On Input No. 1 (and No. 2) discrete inputs (referred to as the mic-on
inputs). When TP13K is wired to the one state, the SDU utilizes the switched
PTT and/or MCDU/SCDU line switch(es) (referred to as switched PTT) method
for cockpit hookswitch signaling on the mic-on inputs. When TP13K is wired to
the zero state, the SDU utilizes the latched audio control panel SATCOM
microphone switch (referred to as the latched ACP) method. These two
methods are described below.
(2) Switched PTT Method
(a) With the switched PTT method, the SDU assumes the mic-on inputs are wired to
conventional microphone momentary push-to-talk switches (i.e., they are
dynamically active [on/off] throughout the duration of the call). The SDU
assumes the air- or ground-initiated call annunciation to have been
acknowledged (i.e., the call to be in the off-hook state) when the appropriate
mic-on input is activated (connected to ground) for the first time after the call
annunciation for a particular channel. Successive activations of that mic-on input
for the duration of that call have no effect on the status of that call until the call
has been cleared.
(b) With the switched PTT method, the off-hook state is also entered following
activation of the Answer Call line select switch on the MCDU/SCDU. The
on-hook state is entered following activation of the End Call line select switch on
the MCDU/SCDU that results in call clearing.
(c) This method also allows usage of the place/end call discrete input and
associated switch to initiate calls to preselected numbers, as well as to terminate
existing calls.
(3) Latched ACP Method
(a) With the latched ACP method, the SDU assumes the mic-on inputs are wired to
SATCOM microphone select switches on the ACP that are latched on
(connected to ground) for the entire duration of a call. The SDU considers the
air- or ground-initiated call annunciation to have been acknowledged (i.e., the
call to be in the off-hook state) when the appropriate mic-on input is active
(connected to ground) for a particular channel. The call is cleared and the
channel is considered to be in the on-hook state when the mic-on input is in the
open-circuit state.
(b) With the latched ACP method, all hookswitch signaling for answering and
terminating all air- and ground-initiated calls is handled by the mic-on inputs; the
MCDU/SCDU Answer Call and End Call options are blanked (the MCDU/SCDU
is only necessary for specifying the called-party number and initiating the call
process for air-to-ground calls).
(c) This method also allows usage of the mic--on discrete input and switch to initiate
calls to preselected numbers.

TESTING/FAULT ISOLATION
1. Overview
A. General
(1) This section defines the built-in test equipment (BITE) requirements for the MCS
system (i.e., SDU and HPA). Information supplied in this section describes how MCS
system failures are detected, recorded, and reported. See Figure 6-1 for an overview
of the BITE system communications.
(2) System BITE contributes to a number of maintenance functions:
•
•
•
•
Detection of internal and external failures
Storage of in-flight failure data
Reporting failure status in the air and on the ground
Ground test capability for isolating faulty LRUs, performance verification, and
system level testing.

B. Definitions
(1) Degraded Operation
(a) Degraded operation is defined as the condition when the MCS system is
operating with a failure that results in diminished capability (e.g., some, but not
all channel units available, or less than nominal HPA power available).
(2) Failure
(a) A failure is defined as a fault that persists for a predetermined amount of time or
for a predetermined number of samples. The tolerance on all failure timing
criteria is ± 0.5 second.
(3) Intermittent Failure
(a) An intermittent failure is defined as a fault that had been declared a failure,
recovered to its normal valid state, and then is declared to have failed again. A
failure occurrence counter is maintained for each entry in the LRU and system
failure logs to identify intermittent failures.
(4) Fault
(a) A fault is defined as the result of a measurement or comparison that does not
satisfy the test or monitoring result requirements. The test or monitoring result
requirements can require a time element.
(5) Reversion
(a) Reversion is defined as the system response to a failure condition that results in
continued system operation in the presence of the failure, and can result in
degraded system capability.
(6) MCS LRU
(a) The following are defined as the MCS LRUs (i.e., those manufactured by
Honeywell/Thales):
• SDU
• HPA
• HSU.

C. Failure Detection and Reporting Levels
(1) Failures are detected in the MCS system by a wide variety of tests. The immediate
result of failure detection is usually diagnosis of the failure to a specific component or
functional circuit group, on a specific SRU, in a specific LRU. However, some
detected failures may only be able to be diagnosed to a suspect SRU, or only to a
suspect LRU, or only to a pair or group of LRUs and the physical or logical
interface(s) between them. Three enumerated levels of failure diagnosis are defined
in Table 6-1.
Table 6-1.
Level
Levels of Failure
Description
Level I
Diagnosis to the LRU level or its equivalent (e.g., a specific inactive bus, error, or
warning)
Level II
Diagnosis to the SRU (module or circuit card) level
Level III
Diagnosis to the component or functional circuit group level or equivalent (e.g., a
very specific error condition)
(2) All MCS LRUs implement Level I and, where possible, Level II failure detection. Level
I diagnosis primarily supports line maintenance. Front panel displays and automatic
reports to central fault/maintenance systems are only performed to Level I resolution
because they are primarily used to support line maintenance, which is typically limited
to LRU replacement. Level II and Level III diagnosis primarily support shop and
factory maintenance. Level II and Level III failure detection information is stored in
the LRU and system failure logs, and can be displayed on the commissioning and
maintenance terminal (CMT) pages.
D. LRU Coverage
(1) The LRU coverage is defined as the sum of all component failure rates covered by
the BITE circuitry within an LRU, divided by the total of the component failure rates
within that LRU. This coverage is greater than or equal to 0.95 as defined. The LRU
probability of false detection is defined as the sum of all component failure rates of
the BITE circuitry within an LRU divided by the total of the component failure rates
within that LRU. This coverage is greater than 0.01 as defined. The LRU coverage
includes the following:
• All SDU to avionic interfaces, where possible
• All MCS inter-LRU interfaces
• All power supply voltages
• All battery voltages
• All microprocessors/microcontrollers
• All memory devices (RAM, ROM, etc).
(2) All discrete drivers between the SDU and the avionics LRUs have over current
protection and open-circuit detection.

E.
Monitoring and Testing Functions
(1) General
(a) The declaration of an inactive input bus takes precedence over declaration of
one or more data word failures against the LRU driving that bus (i.e., if the bus is
inactive, additional logging and reporting of low-rate failures of individual data
words on that bus are precluded). The failure and recovery criteria is set to make
sure individual data word failures are not declared when the bus is inactive. This
is typically done by setting inactive bus failure criteria (e.g., three seconds) to be
faster than word update rate failure criteria (e.g., five seconds), and inactive bus
recovery criteria (e.g., two seconds) to be longer than word update rate recovery
criteria (e.g., one second).
(b) Unless an LRU providing ARINC 429 data declares itself to have failed, a fault is
declared against that LRU when the ARINC 429 data is faulty. This is determined
by checking (as appropriate for each word) for data inconsistencies, data
out-of-range, uses of undefined or reserved values, and occurrences of the
failure warning state in the sign/status matrix (SSM) field.
(c) Two basic types of failure detection testing performed are: functional tests and
continuous monitoring (CM). The purpose of functional testing in the form of
power-on self test and person-activated self test is to exercise the equipment in a
manner as closely as possible to its normal operation. Failures detected during
functional testing are declared to be current failures until a subsequent functional
test shows the failure condition has recovered.
(d) The purpose of continuous monitoring is to test the equipment in a nondisruptive
manner while it is performing its normal operations. Such testing usually includes
monitoring the power supply voltages, temperature sensors, bias currents, input
bus activity, buffer overflow, input data failures, etc. This testing can also include
abnormal failures that cannot be tested as part of the functional testing, such as
protocol failures, processor instruction traps, data loader problems, etc.
(2) Power-On Self-Test
(a) General
The power-on self-test (POST) is a series of functional tests for individual
LRUs; each MCS LRU performs its own internal POST upon a cold start. A
cold start is defined as the response of an LRU where no retention of any
previously stored information in any volatile memory is assumed. The power
supply provides signals to help an orderly power-down and power-up
process for the LRU during power interrupts of any length. Primary power
interrupts of less than 5 milliseconds duration have no effect on system
operation. For primary power interrupts longer than 5 milliseconds and up to
200 milliseconds duration, the LRU maintains normal operation, except the
RF transmit and receive processes do not need to be supported in any LRU
during this interval. For primary power interrupts greater than 200

SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
MCS--4200/7200 Multi--Channel SATCOM System
The POST sequence of tests does not terminate when an out-of-tolerance
condition is encountered. Instead, the sequence continues to complete as
many tests as possible to record all available information regarding existing
failures. An individual LRU that successfully passes POST is declared to be
fully functional. POST must take into account failures detected by
continuous monitoring (i.e., if POST passes, but testing unique to
continuous monitoring has detected and logged a current failure, then the
POST result is logged as a failure).
After executing its own POST, the SDU commands a system-wide functional
test of the HPA(s), HSU and ACU/BSU(s) (including the HGAs, HGA
diplexer/LNA, and HPR) as applicable for the installed equipment in
accordance with the system configuration pins (see MECHANICAL
INSTALLATION). The SDU then processes the results of the functional tests
from these LRUs. The SDU commands the functional test as follows
through:
• BIT request in the HSU command word
• SSM field of the HPA command word(s) for the HPA
• SSM field(s) for the ACU/BSU control word(s) for the ACU/BSU(s).
The BITE status from the LGA diplexer/LNA is continuously sent to the SDU,
with no functional test command necessary or possible. Test results from the
HGA(s), HGA diplexer/LNA, and HPR are reported by the ACU/BSU(s).
The SDU allows up to 30 ± 1 seconds for other system LRUs, except the
HSU, which is allowed 60 ± 1 seconds to report their POST results following
initiation of a system-wide functional test. If an LRU fails to report its
functional test results within this time period, but otherwise meets the ARINC
429 bus communication rate requirements, the SDU considers that LRU to
have failed. If no ARINC 429 bus communication is received on a particular
bus, the SDU considers that bus to be inactive.
(b) Test Initiation
The correct operation of much of the internal circuitry of the SDU depends
on clocks derived from the high-stability frequency reference generated by
the oven-controlled crystal oscillator (OCXO). Therefore, it is inappropriate to
perform BITE tests until this clock frequency has achieved gross stability. If
the SDU is powered on after having stabilized at a cold external temperature
(e.g., --55° C), it can take several tens of seconds for the frequency drift rate
to be low enough before the phase locked oscillators (PLO) that derive the
dependent clocks can lock onto the OCXO frequency reference.

MCS--4200/7200 Multi--Channel SATCOM System
The SDU defers testing of sensitive equipment until a positive indication of
settling is detected, or sufficient time passes so the lack of settling itself can
be classified as a failure. Deferral of these sections of POST also result in
normal operation being deferred, including access to the user interfaces
(SCDU, CFDS, and CMT) and all automatic calibration processing.
Consequently, the SDU suspends POST until the SDU detects the first of
the following conditions:
• OCXO heater monitor indicates it has achieved operating temperature.
• Power supply unit (PSU) temperature sensor indicates a reading above
25 °C.
• Channel filter module transmit and receive PLO lock detectors both
indicate that lock has been achieved.
• More than 4 minutes have elapsed since primary power was applied.
(c) LRU Front Panel LED and Alphanumeric Display Tests
A test of the HPA and HSU front panel LEDs is performed as a part of each
POST. At a minimum, this is made up of flashing the LEDs on and off. The
LED flashing continues until POST is completed or for 3 ± 0.5 seconds.
During the test, the SDU tests its alphanumeric display by incorporating one
or more occurrences of the word TESTING into its display sequence to
make sure all display elements are tested.
(d) RF Loop Back Tests
As part of the system-wide POST, the SDU implements a RF loop back test.
The RF loop back occurs in the radio frequency module (RFM) installed in
the SDU.
The SDU delays initiating the RF loop back test until it receives an indication
the RF loop back has been activated. If the SDU fails to receive a valid
indication within 30 seconds following the RF loop back request, then the
SDU completes its POST without executing the RF loop back test. The SDU
cancels the RF loop back request when the loop back test is completed, or if
the 30 second timer expires while waiting for verification of an active RF loop
back.
(3) Person-Activated Self-Test
(a) The person-activated self-test (PAST) performs the same functions as POST.
PAST is initiated in the HPA and the HSU by pushing the PUSH-TO-TEST (PTT)
switch on the respective LRU front panel. PAST can also be initiated any time
through:
• Respective CMT interface to the LRU
• SSM field of the HPA command word sent to the HPA from the SDU
• BIT request in HSU command word sent to the HSU from the SDU.

SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
MCS--4200/7200 Multi--Channel SATCOM System
(b) A stuck switch on the CMT or LRU front panel does not cause PAST to remain
active. Any switch activity is ignored while PAST (or POST) is executing.
(c) The HPA and HSU inhibit PAST while the aircraft is airborne, except when PAST
is initiated through the CMT, which is permitted at any time. The HPA and HSU
cannot properly function if not receiving valid command words from the SDU
containing the air/ground status and command information. Under these
conditions, the HPA and HSU are not usable by the SDU. PAST is only permitted
while the aircraft is on the ground, or when the airborne/on-ground status is
unknown. In lieu of the airborne/on-ground status information from the SDU, the
HPA and HSU permit PAST as though the aircraft is on the ground.
(d) A system-wide PAST is initiated in the SDU when commanded by:
• Entry through the SATCOM control and display unit (SCDU)
• Entry through the central maintenance computer (CMC)
• Entry through the central fault display system (CFDS)
• Command from the CMT
• Activating the PTT switch (SDU TEST) on the front panel.
(e) A stuck switch on the SDU front panel does not cause PAST to remain active.
Any switch activity is ignored while PAST (or POST) is executing.
(4) Continuous Monitoring
(a) Continuous monitoring (CM) of the BITE circuitry does not interfere with the
normal operation of the system. Instead any failure condition is recorded and
reported. Continuous monitoring operates as a background task at all times,
even during functional testing. Functional test failure codes that are identical to
the continuous monitoring codes (except for the MSB of the level 3 code)
indicate cases where the functional test differs in some way from the companion
CM test. Those CM failures detected during functional testing (e.g., maintenance
and status word failures) are logged as CM failures, not functional failures.
F.
Failure Recording
(1) The SDU records CFDS internal failures at all times. The SDU only records CFDS
external failures while receiving a valid All Call DC1 Command if a Douglas or Airbus
CFDS is installed. Internal failures are defined as those internal to the SATCOM
subsystem. External failures are defined as those external to the SATCOM
subsystem. If a Boeing CMC (or no CFDS) is installed or if valid DC commands are
not available, then the air/ground status is used to generate pseudo DC states of
DC0 (aircraft on-ground) and DC1 (aircraft airborne).
(2) The HPA records internal failures at all times. The HPA only records external failures
while the aircraft is airborne, based on the status of the weight-on-wheels discrete
(on-ground vs. airborne). Internal failures are defined as those that have the same
Level I code as the LRU recording the failure (i.e., 01 for the SDU, 04 for the HGA
HPA, and 07 for the LGA HPA). External failures are defined as those failures not
having the same level 1 code as the LRU recording the failure.

(3) The HPA and HSU store their functional test and CM failure records in nonvolatile
memory designated as the LRU failure memory log. Each LRU failure memory log is
capable of being interrogated and cleared. The SDU contains a nonvolatile memory
that serves as a system failure memory log. Functional test results supplied by the
HSU, HPA(s), ACU/BSU(s), LGA diplexer/LNA, and the SDU itself are recorded in
this system failure memory log. The system failure memory log is capable of being
interrogated and cleared for each LRU individually. Each LRU failure memory log and
the system failure memory log is capable of recording at least 1000 failures.
(4) The HPA, HSU and other system LRUs supply failure information to the SDU for
storage in the system failure memory log. In the absence of any detected failures
during a flight leg, the SDU records the flight leg counter, flight number, ICAO
address, date, and Greenwich Mean Time (GMT) at the flight leg transition. The SDU
also records the aircraft identification for display on the SCDU and CFDS
maintenance pages.
(5) Class -- The SDU declares and stores the classification (Airbus/Douglas CFDS) of
failure (one, two, three) for each entry in this field.
• Class 1 failures are indicated in flight to the crew by the CFDS because they have
operational consequences for the current or next flight(s).
• Class 2 failures are not automatically indicated in flight to the crew by the CFDS
because they have no operational consequences for the current or next flight(s),
but are indicated to the crew on the ground because they cannot be left
uncorrected until the next routine scheduled maintenance check.
• Class 3 failures are not indicated to the flight crew because they can be left
uncorrected until a routine scheduled maintenance check. An accumulation of
Class 3 failures can lead to a Class 2 or Class 1 failure.
• Aircraft Identification -- The aircraft identification (i.e., the tail number) is made up
of nine alphanumeric characters. The SDU obtains the aircraft identification from
the CMC or CFDS through ARINC labels 301, 302, and 303 (if available).
G. Failure Reporting
(1) General
(a) Active failures include those internal and external failures deemed to be currently
failing while the aircraft is on the ground or airborne. Unlike failure recording that
excludes recording external failures while on the ground, failure reporting has its
own set of criteria as specified in the following paragraphs.
(2) HPA Failure Reporting
(a) General
The HPA reports its functional test/CM failure status by lighting its front panel
LEDs, and through communication to the SDU.
(b) HPA Front Panel Indicators and Controls
The HPA indicators and controls are given in Table 6-2.

(c) HPA Front Panel LEDs
Functional testing effectively controls the on/off state of the front panel LEDs
during the period beginning with initiation of the functional testing
(POST/PAST), through execution of the functional test sequences (including
LED testing), and up to and including the indication of the test results on the
LEDs. Continuous monitoring exclusively controls the LEDs at all other
times.
The green LED (PASS) lights for 30 ± 5 seconds at the conclusion of the
functional test sequences if both of the following are true:
• The HPA determines there are no currently active CM failures having its
own Level I code (i.e., 04 or 07, as applicable)
• No functional test failures have been detected with its own Level I code.
There must be no known failures in order to light the green LED as the
functional test indication.
The red LED (FAIL) lights continuously during the functional test indication
phase and through the transition to the CM indication phase, if the HPA
detects at least one currently active CM failure with its own Level I code. If
the HPA detects only functional test failures (i.e., no CM failures are
currently active), the red LED lights for 30 ± 5 seconds and is then turned
off.
The red LED also lights as long as the failure persists, if the HPA detects
any CM failure that has its own Level I code while continuous monitoring is
controlling the LEDs. Otherwise, both LEDs are turned off. Continuous
monitoring itself never causes the green LED to light. The presence or
absence of functional test failures does not affect the CM indication.
(d) HPA-SDU Communication
The HPA communicates its functional testing/CM failure status to the SDU
through the HPA maintenance and status words. The HPA only indicates a
FW SSM state in its maintenance and status words, and active discrete
failure bits in its maintenance word. Since no failures unique to functional
testing activate the SSM FW state or the discrete failure bits in the
maintenance word, no functional test failures need to be latched until the
next functional testing sequence.

LED testing), and up to and including the indication of the test results on the
LEDs. Continuous monitoring exclusively controls the LEDs at all other

The green LED (PASS) lights for 30 ± 5 seconds at the conclusion of the
functional test sequences if both of the following are true:
• The HSU determines there are no currently active CM failures having its
own Level I code (i.e., 03)
• No functional test failures have been detected with its own Level I code.
There must be no known failures in order to light the green LED as the
functional test indication.
The red LED (FAIL) lights continuously during the functional test indication
phase and through the transition to the CM indication phase, if the HSU
detects at least one currently active CM failure with its own Level I code. If
the HSU detects only functional test failures (i.e., no CM failures are
currently active), the red LED lights for 30 ± 5 seconds and is then turned
off.

The red LED also lights as long as the failure persists, if the HSU detects
any CM failure that has its own Level I code while continuous monitoring is
controlling the LEDs. Otherwise, both LEDs are turned off. Continuous
monitoring itself never causes the green LED to light. The presence or
absence of functional test failures does not affect the CM indication.
(d) HSU-SDU Communication
The HSU communicates its functional testing/CM failure status to the SDU
through the HSU status word. The HSU indicates a FW SSM state in its
status word, when failures are present that prevent it from offering HSD
service.
For certain failures detected during continuous monitoring, the appropriate
discrete failure bits and the SSM FW state are set within the maintenance
and status words as long as the failure persists.
(4) SDU Failure Reporting
(a) General
The SDU reports its functional testing/CM failure status and all other system
LRUs by:
• Activating its alphanumeric display
• Communicating to the SCDU, CMC, CFDS, and CMT interfaces.
The alphanumeric display indicates all applicable failure conditions with no
regard to:
• Any type of internal/external failure differentiation
• Any CFDS failure class distinctions
• Which LRU detected a failure (either the SDU itself or one of the reporting
LRUs in the SATCOM subsystem).
The SDU delays reporting the results of the functional test sequence for a
period of 5 seconds. This gives continuous monitoring the opportunity to
perform its unique tests during the delay period, and include any current CM
failures in the test report. The SDU takes a snapshot at the end of the
functional test delay period to include all currently active CM failures in
addition to all failures detected during functional testing. The functional test
delay period applies to the SDU alphanumeric display, the SCDU
maintenance pages, the CFDS pages, and the CAIMS and CMC fault
summary words, but not to the CMT.

(c) Front Panel Alphanumeric Display and MANUAL SCROLL Button
General
The alphanumeric display makes it easy for the maintenance personnel
to identify which system LRU has failed. The alphanumeric display is
blank unless specifically activated for temporary display of failure
messages and other status information. The alphanumeric display is
also kept blank under conditions of extreme temperatures. The display
is not intended to be started when its temperature is less than --5 °C, or
greater than +30 °C. The alphanumeric display is started during the LED
test portion of the functional test sequence. After the functional test
delay period, and any time during continuous monitoring, the
alphanumeric display can be started by pushing the MANUAL SCROLL
button.
The operator can scroll the alphanumeric display through the entire
applicable message sequence by repeatedly pushing the MANUAL
SCROLL button within 30  5 seconds after the display is started. One
left-justified 20-character (or less) message is displayed each time the
MANUAL SCROLL button is pushed. When the end of the display
sequence is reached (i.e., END OF LIST), the next actuation of the
MANUAL SCROLL button returns the alphanumeric display to the top of
the display sequence, enabling the operator to scroll through the
sequence again. Message scrolling is performed according to the
following sequence:
• One of four possible system/SDU pass/fail messages
• All applicable Level I failure messages
• LRU part number messages (up to four lines)
• ORT identification message
• END OF LIST message.
If the MANUAL SCROLL button is inactivate for 30 ± 5 seconds at any
point during the display sequence, the alphanumeric display is blanked
and any display sequence in progress is aborted. At the same time, one
or both of the front panel LEDs (as appropriate) are turned off if they
were exclusively indicating functional test failures with no current CM
failures.

CM status, takes on one of four possible states:
• SDU PASS
SYS PASS
• SDU PASS
SYS FAIL
• SDU FAIL
SYS PASS
• SDU FAIL
SYS FAIL.
Level I Failure Messages
This section lists all the applicable Level I failure messages that can be
displayed on the alphanumeric display, along with the appropriate LRU
or control bus input. These messages are listed in failure code order in
Table 6-5. For the functional test display, the message list includes all
the active failures in the snapshot and the list is static.
For continuous monitoring, the message list includes all currently active
CM failures. The presence or absence of functional test failures does
not affect the CM message list. The failure message list for the CM
display is potentially dynamic.
During continuous monitoring, if a new CM failure becomes active
during the scroll sequence, the respective message appears at its
proper location in the sequence according to its Level I code. This
occurs either during the current scroll sequence if that Level I code has
not yet been reached, or during the next scroll sequence if the failure is
still active. If a CM failure recovers during a scroll sequence, its
message does not appear in any subsequent scroll sequence, even if it
had appeared earlier. If a CM failure recovers while its particular
message is currently being displayed, the message continues to be
displayed until the MANUAL SCROLL button is activated or until the
time-out period expires.

LEVEL 1 FAULT XX
XX is the Level 1 failure code (undefined)
NOTE: The front panel display messages associated with failure codes CBx and CCx (WRG:SDI/HPA HI--GAIN and
WRG:SDI/HPA LO--GAIN, respectively) are identical to the messages raised for failure codes D1x and D2x,
respectively. This use of a single front panel display message for multiple failure codes (where the CB/CCx
codes reflect detection by the HGA/LGA HPA of an invalid HPA SDI strap condition, while the D1/D2x codes are
generated by the SDU in response to a report from the HGA/LGA HPA of having detected an unexpected SDI
code) is deliberate, and results from alignment of the front panel display messages with their CFDS/CMC
counterparts. Because of this approach, it is possible (in this specific case) for an operator to receive two
consecutive front panel display messages that are the same.

LRU Identification (Part Numbers) Electronically
Following the display of all Level I failure messages, a list of the
available LRU end-item part numbers is displayed. This list only includes
part numbers for those LRUs present in the given installation as defined
by the system configuration pins (see MECHANICAL INSTALLATION).
For an installed LRU whose end-item part number is not available,
dashes are displayed in place of the part number (e.g., HPL _ _ _ _ _ _
_ _ _ _ _). The list of part numbers are displayed in the order given in
Table 6-6.

NOTES:
1.
bbbbbbb represents the seven-digit LRU end-item base part number.
2.
hh represents the two-digit LRU end-item hardware configuration number.
3.
sss represents the three-digit LRU end-item software configuration number.
4.
nn represents the two-character LRU end-item software modification level (possibly including space, dash
characters, and alpha characters).
For the SDU, the two-digit LRU hardware configuration number must be
entered manually through the CMT interface for valid data to be
available for display. This data is stored during LRU end-item testing. All
other numbers reside within the LRU software. All numbers are
communicated to the SDU by Honeywell/Thales HSU and HPA(s)
through the part number block transfer. For non-Honeywell/Thales
interfacing HPAs, no such data is available to the SDU, therefore,
dashes are displayed for the HPA end-item part number.
ICAO Aircraft Address
Following the display of the LRU End Item part numbers, the ICAO
aircraft address is displayed in octal and hexadecimal formats as shown
below:
ICAO--XXXXXXXX YYYYYY
Where “XXXXXXXX” represents the octal format and “YYYYYY”
represents the hexadecimal format. If the ICAO is provided from an
ARINC 429 source, as determined by the state of configuration pin
TP10A, and a valid ICAO has not been received, the octal and
hexadecimal values are replaced with dashes.

HSD Channel ISN
Following the display of the ICAO aircraft address, the Inmarsat Serial
Number (ISN) for each installed HSD channel is displayed as shown
below:
ISNX: YYYYYY ZZZZZZ
Where “X” is a decimal number from 1 to 4 used to distinguish multiple
ISNs, and where “YYYYYY” represents the Type Approval ID and
“ZZZZZZ” the Forward ID. The ISNs for each installed HSD channel are
displayed on a separate line. If the ISN for an installed HSD channel is
not available, dashes are displayed in place of the Type Approval ID
and the Forward ID.
ORT Identification
Following the display of the ISNs, if one or more HSD channels are
installed, or after the ICAO, if no HSD channels are installed, the user
ORT identification is displayed as specified:
• ORT ID--XXXXXXXXXXXXX (first line)
• XXXXXXXXXXX--MODIFIED (second line, after another activation of
the MANUAL SCROLL button).
Where XXXXXXXXXXXXXXXXXXXXXXXX represents the 24-character
description contained in the user ORT description field. The user ORT
description field is used to annotate a particular set of ORT items to
identify one from another (e.g., NORTH PACIFIC ROUTE, SOUTH
ATLANTIC ROUTE, 747--400 ASIAN ROUTE, 777 ASIAN ROUTE).
Alternatively, this item could contain a software identification (e.g., a
software part number for the user ORT as a released entity).
The MODIFIED flag is only displayed if the state of the user ORT
modified flag indicates any item in the user ORT has been modified
since the user ORT was created. When any user ORT item is modified
by the SDU software, either directly or indirectly, the user ORT modified
flag is set to MODIFIED. If the state of the user ORT modified flag is
unmodified, the MODIFIED flag is not displayed. The state of the user
ORT modified flag is never set to unmodified by the SDU software.
The next two pushes of the MANUAL SCROLL button present the same
information for the Secured ORT partition.
SDU Temperature
Following the display of the ORT Identification, the SDU temperature is
displayed as shown below:

Where “XXX” represents the numeric display of the actual SDU
temperature in degrees Celsius, with a (--) sign or space as appropriate
for negative and positive values. The “XXX” field will have leading zeros
replaced by spaces.
End Of List Message
The END OF LIST message is displayed at the end of the display list
after the ORT identification.
H. Miscellaneous BITE Requirements
(1) The typical retention period for the BITE memory is at least five years at 25 °C. The
worst case retention period is at least one year at 50 °C. If batteries are used to
supply backup power for the BITE memory, the typical battery lifetime should be at
least 10 years at 25 °C. The worst case lifetime is at least two years at 50 °C.
(2) Each system LRU has a total on-time clock (TOTC) to accumulate and record the
amount of time the LRU has been powered up. The TOTC has a 10 minute
resolution, and is capable of accumulating and recording a count of at least 200,000
hours.
(3) The TOTC value is capable of being examined, and of being reset to 0:00 through
the CMT. Any manual TOTC reset, or any automatic TOTC reset (e.g., upon
detection of corruption of its value), results in an automatic entry of the event into the
LRU failure memory log and the SDU system failure memory log. The TOTC hours
are capable of being automatically entered into the LRUs maintenance activity log.
I.
Maintenance Activity Log
(1) A maintenance activity log is stored in each system LRU. The maintenance activity
log is made up of the six most recent maintenance activity records (MAR). Each MAR
can be entered through the CMT. Information is stored in the MAR as shown in
Table 6-7 and in the order listed.

(2) The fields are defined as follows:
• Document number -- The document number has up to 16 alphanumeric
characters. The intent of this field is to supply maintenance activity traceability.
• Date field -- The date field is made up of six numeric characters in the format of
yymmdd, where yy represents the year, mm represents the month, and dd
represents the day. This field is entered automatically by the SDU as determined
by its internal real-time clock (RTC); it is entered manually for the HPA. The intent
of this field is to record the date the maintenance activity was performed.
• Location field -- The location field has up to 32 alphanumeric characters. The
intent of this field is to indicate the place where the LRU maintenance service was
performed.
• Phone number field -- The phone number field is made up of 18 numeric
characters. The intent of this field is to supply a phone number of who performed
the LRU maintenance. This phone number should include the combination of
country code, area code, and local phone number.
• Total on-time clock field -- The TOTC field is made up of six numeric characters
representing hours. This field is entered automatically by the LRU as determined
by the internal TOTC.
2. SATCOM Control and Display Unit
A. General
(1) The SATCOM Control and Display Unit (SCDU) menu formats obey the accepted
industry standards for multifunction (multipurpose) control and display units (MCDU).
The following paragraphs describe the SCDU display layout and terminology used to
describe the display, font size conventions, scratchpad usage, format, keyboard
usage, display symbols, and update rates.
B. SCDU Display Terminology and Basic Operation
(1) General
(a) The SCDU display is made up of 14 lines of 24 characters. The top line (line 1) is
referred to as the title line and the bottom line (line 14) is referred to as the
scratchpad. Lines 2 thru 13 are arranged into six pairs having a label line and
data line. The SDU communicates to the SCDU for all data to be displayed in
green. The color displayed on the MCDU depends on how the MCDU responds
to this communication.
(b) There are six line select (LS) keys on each side of the SCDU display designated
left (L) and right (R) and numbered 1 to 6 from top to bottom. The LS keys are
associated with a pair of display lines where the upper line of a pair is the label
line and the lower line is the data line. The LS key/line pair relations are given in
Table 6-8.

(c) The SCDU can display a large and small font size. Different character fonts are
not shown in the example SCDU page figures given in this section. The use of
large font is indicated by the presence of uppercase letters in the SCDU page
figures, while the use of small fonts are demonstrated by lowercase letters. In
general, page names displayed in the title line are in large font. For pages where
p/t is specified to be displayed in the title line, the p/t is in small font. Data
entered into the scratchpad is displayed in large font. Data in the label lines is
displayed in small font, while data in the data lines is displayed in large font.
Numerical character font sizes cannot be shown in the figures, but their font
sizes follow the same conventions.

(d) Labels on the left side of the SCDU display are displayed beginning in column 2
of the label line. Data on the left side is left-justified in the data line. Labels and
data on the right side of the SCDU display is right-justified. This is the case
unless specified otherwise.
(2) Scratchpad
(a) General
The scratchpad is used for data entry and displaying SDU generated
messages. Pushing an alphanumeric key on the keypad (0 through 9, A
through Z, +/-- [plus or minus], / [slash, space]) enters that character into the
scratchpad. The scratchpad is not used for fixed format display purposes.
The mechanism used for data entry is described below.

SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
MCS--4200/7200 Multi--Channel SATCOM System
(b) Data Entry
When the user types the appropriate characters using the SCDU keypad,
the characters are echoed on the scratchpad. After data entry, the user must
push the appropriate LS key adjacent to the data field where the data is to
be displayed. The SDU then checks the data for format and acceptability
(out-of-range, entry not permitted into the field, etc). If the data is incorrect,
the SDU leaves the previous data in the field and displays the appropriate
error message in the scratchpad. If any LS key is pushed adjacent to a
blank or nonselectable field, the scratchpad message 1 (i.e., NOT
ALLOWED) is issued. If the entry was rejected because an incorrect LS key
was pushed, the entry is accepted if the correct LS key is subsequently
pushed.
(c) Scratchpad Message
If the SDU determines a data entry does not conform to format or
acceptability requirements after an entry is attempted, the SDU issues a
scratchpad message prompting the user for the correct data. The user can
clear a scratchpad message by using the clear (CLR) key, or by entering
data into the scratchpad over the message.
(d) CLR and DEL Keys
General
The CLR and delete (DEL) keys are used to clear the scratchpad and
alter the data fields. Generally, for MCDUs that have only a CLR key
(e.g., Airbus and Douglas) the scratchpad is cleared and the data fields
are altered by using this key. For MCDUs that have both CLR and DEL
keys (e.g., Boeing), the scratchpad is cleared using the CLR key, while
the data fields are altered using the DEL key.
CLR Key
Pushing the CLR key clears the scratchpad message. When the
scratchpad contains user-entered characters, momentary actuation of
the CLR key clears the last entered character, while continual actuation
of the CLR key clears the entire contents of the scratchpad.
When the scratchpad is empty, pushing the CLR key causes CLR to be
displayed in the scratchpad indented five spaces. If an LS key is pushed
and the field adjacent to the LS key is specified to be either erasable
(e.g., an unprotected number) or a default maintained value (e.g.,
protected number priorities), the field is cleared or reverts back to its
default value, as applicable.
For compatibility with the Boeing 777 AIMS/CDU, the SDU clears the
entire scratchpad when the CLR command is received with the repeat
bit set.

15 Jul 2006
SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
MCS--4200/7200 Multi--Channel SATCOM System
DEL Key
The DEL key (if available) can be used to clear or revert the data fields.
Pushing the DEL key causes no response when the scratchpad is not
empty, except for either an SDU issued error message or pilot-entered
characters.
When the scratchpad is empty, pushing the DEL key causes DELETE to
be displayed in the scratchpad.
NOTE: Pushing the DEL key again does not clear DELETE from the
scratchpad. Instead, pushing the CLR key when DELETE is
displayed in the scratchpad clears DELETE.
If an LS key is pushed and the field adjacent to the LS key is specified
to be either erasable (e.g., an unprotected number) or a default
maintained value (e.g., protected number priorities), the field is cleared
or reverts back to its default value, as applicable.
When the scratchpad contains CLR indented five spaces as the result of
the CLR key being pushed with an empty scratchpad and the DEL key
is subsequently pushed, the SDU replaces CLR with DELETE in the
scratchpad.
(e) NEXT PAGE and PREV PAGE Keys
General
NEXT PAGE Key
Pushing this key causes the next page in the sequence to be displayed.
If the last page in a multiple page sequence is displayed and the NEXT
PAGE key is pushed, the first page is displayed. The SDU ignores this
key if the key is pushed when p/t is not displayed, or if a p/t display is
the value 1/1.
PREV PAGE Key
(f)
Pushing the NEXT PAGE and PREV PAGE (if available) function keys
on the SCDU keypad causes the SDU to display the next page, or
previous page of the display sequence where appropriate (i.e., when p/t
is displayed in the title line).
Pushing this key causes the previous page in the sequence to be
displayed. If the first page in a multiple page sequence is displayed and
the PREV PAGE key is pushed, the last page is displayed. The SDU
ignores this key if the key is pushed when p/t is not displayed, or if a p/t
display is the value 1/1.
Special Symbols
When displayed, special symbols are defined as given in Table 6-9.

Special Symbols
Description
* (Asterisk)
Pushing the LS key adjacent to this symbol (when it appears) causes an
action of some kind to occur (e.g., making a phone call, sorting a phone
list, or initiating log-off).
[ ] (Brackets)
Empty brackets prompt the user for data entry into the field. However, data
entry is not mandatory. Brackets surrounding data indicate the data is
unprotected and can be modified or deleted. Not all fields modifiable are
surrounded by brackets. When brackets are used to enclose existing data,
as opposed to prompting entry of data into an empty field, they are
intended as an indication the data is unprotected (i.e., an unprotected
phone number). Conversely, protected phone numbers do not have
brackets, indicating the phone number cannot be modified or deleted.
< , > (Carets)
A caret adjacent to an LS key indicates if the key is pushed the display
changes to a new page. The new page is either the one indicated next to
the caret or, in case of RETURN>, the higher level page.

Indicates the data in the field is currently selected (e.g., the selected GES
or antenna).
(g) Updates
Dynamically generated display fields, whose contents have changed, are
updated by the SDU both periodically (at a rate of at least 1 Hz), and upon
completion of an LS key action that could have caused the display or the
display field to change. With multiple SCDU configurations, the SDU only
maintains one version of each page for display. The SDU responds to LS
key actuations from all SCDUs in a serial fashion and updates the display
page(s). Each SCDU scratchpad and the channel selection fields are
independent from all others, allowing each user to perform independent
actions.
C. SCDU Page Hierarchy
(1) The SCDU page hierarchy is shown in Figure 6-2. The SATCOM MAIN MENU page
is accessed by pushing the LS key adjacent to  prompt is displayed on the right adjacent to the 6R key,
as opposed to the left.
• The SDU issues scratchpad message 1 (i.e., NOT ALLOWED) if any LS
key is pushed adjacent to a blank or display-only field.

(b) TEST page
If a system-wide functional test (i.e., PAST) is initiated from the SCDU
interface (i.e., by pushing the 2R key on the SATCOM MAINTENANCE
page), the first access of the SATCOM subsystem from an SCDU MAIN
MENU page after the POST/PAST Results Delay period causes the TEST
page to be shown with the status of the current failures. However, the TEST
page shows the TEST IN PROGRESS 60S message if this first access
occurs during the POST/PAST Results Delay period. If the SATCOM
subsystem is not accessed within 5 minutes of the completion of an
SCDU-initiated PAST, the page hierarchy is reset to its original structure as
shown in Figure 6-2.

When the 2R key is pushed on the SATCOM MAINTENANCE (i.e., SAT--N)
page, the SDU initiates a PAST and the page display temporarily goes to the
TEST page where TEST IN PROGRESS 60S is displayed. However, the
SCDU eventually times out the SATCOM subsystem and takes back control
of the display. This is due to the fact that for SCDU-accessed maintenance
pages, the SDU interfaces directly with the SCDU (as opposed to going
through the CFDIU) and is unable to maintain proper bus activity (which the
CFDIU normally does) during initial execution of the PAST.
To display the test results, the user must reselect the SATCOM system by
pushing the LS key adjacent to the  beginning in column 1 when the test is active. If the log--on
state changes from Standby to any other state while the test is active,
the test is terminated. The commands on lines 4 and 5 are shown only if
the configuration straps indicate this channel is wired for headset use.

current displayed page, and t represents the total number of pages
needed to show the current failures. The display of the slash is always
in column 22, with p right-justified to the slash and t left-justified to the
slash.
Line 3
This line displays headers ATA beginning in column 1 and CLASS
beginning in column 20 if there are current failures to report after
execution of a PAST. This line is blank if there are no failures to report.
In addition to the above, for CFDS type none, the header ATA is not
displayed (CLASS is still displayed as specified).
Line 5
This line displays the message TEST IN PROGRESS 60S beginning in
column 3 within one second of a PAST being initiated on the SAT--N
(i.e., SATCOM MAINTENANCE) page, and then throughout the duration
of PAST. If there are no current failures to report at the conclusion of the
PAST (including the POST/PAST results delay period), the message
TEST OK is displayed. If there are current failures to report at the
conclusion of the PAST (including the POST/PAST results delay period),
refer to paragraph 4 for line requirements.

Other Information
The SELF--TEST page lists two failures per page if failures are detected
during the PAST(self--test). These two sets of lines (lines 5, 6, and 7
and lines 9, 10, and 11) display Level 1 diagnosed current failures.
Failures are shown in chronological order (i.e., the most recent detected
failure last) with no more than two failures displayed per page.
The number of TEST pages depends on the number of current failures
to report (up to a maximum of 99 pages). When there is an odd number
of current failures to report, the odd failure is displayed on a separate
page in lines 5, 6, and 7, and lines 9, 10, and 11 are blank. If there are
no failures to report, lines 5, 6, 7, 9, 10, and 11 are blank except as
noted in paragraph 3.
Line 5 and, if applicable, line 9 display the ATA number beginning in
column 1 and the class number beginning in column 23. The ATA
number is displayed as aaaaaa, where aaaaaa represents the ATA
reference number of the reported failure as specified in paragraph 3.E.
for each type of CFDS. For CFDS type none, no ATA number is
displayed. The class number is displayed as c, where c represents the
class (1, 2, or 3) of the failure.
Lines 6 and 7 and, if applicable, lines 10 and 11 display a text message,
as specified in paragraph 3.E. for each CFDS type, for the reported
failure beginning in column 1.

are displayed, pushing the left LS key adjacent to the desired action
commands the data loader to initiate that action.
Uploads are allowed regardless of the log-on state (composite uploads
are inhibited only by ORT item liv and not the log-on state).
Once a left LS key is pushed, the  message is displayed to the
right of the selected data loader action, right-justified. The data loader
status changes to BUSY and data transfers occur. There is only one
data loader command selected at a time. The  message remains
displayed until the 6L key is pushed if the data loader status becomes
ERROR after a left LS key is pushed. When the data transfer is
completed, or after an error has been acknowledged, the 
message is removed and the data loader status changes appropriately.

When the START prompt is selected by pushing the 5L key when the
data loader status is READY:
• Periodic data logging starts
• The asterisk next to START is removed
• The  message is displayed beginning in column 8
• STOP is displayed adjacent to the 5R key.
Periodic data logging continues until the 5R key is pushed, at that time
the data line display reverts to its original state (i.e., only the START
prompt with or without an asterisk as appropriate).
The  message remains displayed and the STOP prompt is
blanked if the data loader status changes to ERROR after periodic data
logging has started. This condition remains until the error is
acknowledged by pushing the 6L key and/or the data loader status
changes, at that time the data line display changes as appropriate.
Field 6L
6L -- This data line displays the *ACK ERROR prompt. This prompt is
displayed when the data loader status is ERROR. Pushing the 6L key
causes the SDU to remove the ERROR status and display the current
data loader status (i.e., NOT CONNECTED or CONNECTED) in the 1L
data line.
The SDU completes the upload/download data transfer by commanding
the data loader transfer complete function. The data loader responds
with a TRANSFER COMPLETE indication and enters a no loop. To
return the data loader to the READY state, the user must cause the
data loader to read the configuration file on the diskette (i.e., cycle data
loader power or remove/insert the diskette).
Field 6R
6R -- This data line displays the RETURN> prompt. Pushing the 6R key
causes the display to revert to the SATCOM SUBMENU page (or
SATCOM MAINTENANCE page) as appropriate.

The purpose of this page is to display Class 1 and 2, Level 1 diagnosed, failures
reported during previous legs. See Figure 6-11 for example pages.
(b) The Previous Leg Report lists two failures per page if a failure was present
during the previous leg. These two sets of lines display Class 1 and 2, Level 1
diagnosed, last leg failures. Failures within each flight leg are displayed in
chronological order (i.e., the most recent detected failure last) with no more than
two failures displayed per page. However, the flight leg display is in reverse
chronological order (i.e., flights go back in time while failures for each individual
flight go forward in time).
(c) The number of PREVIOUS LEGS REPORT pages depends on the number of
failures to report (up to a maximum of 99 pages). If there are no failures to
report, lines 6, 7, 9, 10, and 11 are blank. Line 5 displays NO FAULT DETECTED
beginning in column 4 if there are no failures to report.
(d) Failures from different flight legs with the same aircraft identification are mixed on
the same page. When the last leg falls in lines 5, 6, and 7, failures from the
previous flight leg are displayed on the same page in lines 9, 10, and 11.
(e) When the given flight leg has a different aircraft identification recorded than the
flight leg before it, the failure display begins in lines 5, 6, and 7 on the next page
of the multiple page sequence. When there are no failures to report for a given
flight leg, nothing is reported for that flight leg (i.e., the flight leg is skipped).

(14) GROUND REPORT (TROUBLE SHOOTING DATA) Page
(a) General
Access to this page is from the GROUND REPORT page. The purpose of
this page is to display Class 1, 2, or 3, Level 1 diagnosed ground failures
that occurred during the last leg ground report. See Figure 6-16 for example
pages.
One failure is listed per page if a failure is present. These lines display Class
1, 2, and 3, Level 1 diagnosed, last leg ground report failure details
corresponding to the Level 1 failures from which the troubleshooting data
was initiated. Failures are displayed in chronological order (i.e., the most
recent detected failure last) with one failure displayed per page.
(b) Line 4
Line 4 displays the date beginning in column 2 and the UTC beginning in
column 8. The date and time are displayed as follows.
The month is displayed as mmm, where mmm represents the month of the
year as JAN, FEB, MAR, APR, MAY, JUN, JUL, AUG, SEP, OCT, NOV, or
DEC.
The day is displayed as dd, where dd represents the day of the month from
01 to 31.
The UTC is displayed as hh:mm, where hh represents the UTC hours from
00 to 23 and mm represents the UTC minutes from 00 to 59. The UTC is the
time the failure was stored in the failure memory log on this flight leg.
Dashes are displayed if no valid UTC data is available.
(c) Line 5
Line 5 displays the LRU abbreviated name of up to five characters that
corresponds to the Level 1 failure code. The SRU abbreviated name of up to
five characters is displayed beginning in column 8. If the SRU designation in
the failure code is 0, no SRU abbreviation is displayed. The LRU failure
code is displayed as two hexadecimal digits beginning in column 17. The
SRU failure code is displayed as one hexadecimal digit beginning in column
20. The failure code is displayed as two hexadecimal digits beginning in
column 22.

MCS--4200/7200 Multi--Channel SATCOM System
3. Maintenance Computer Interface
A. General
(1) The SDU is designed to interface with the Boeing 747--400 Central Maintenance
Computer (CMC) or the Boeing 777 On--board Maintenance System (OMS), the
Airbus Central Fault Display System (CFDS), and the McDonnell Douglas CFDS in
accordance with guidelines outlined in Boeing documents D220U050 (747--400 CMC
-- release date 3 June 1991) and D243W201--1 (777 OMS -- release date 30 October
1992) and Airbus document ABD0048 issue C, all of which supersede ARINC 604 for
their respective applications.
(2) The Boeing maintenance computers (i.e., 747--400 CMC and 777 OMS) are virtually
indistinguishable to the SDU. The operations to support these two systems are very
similar and, therefore, are presented together. The operations to support the Airbus
and McDonnell Douglas maintenance computers are very similar and, therefore, are
presented together. The SDU determines the aircraft type on which the SDU is
installed, and then supports only the functionality required by that particular system.
B. Boeing 747--400 CMC/777 OMS
(1) General
(a) The CMC and SDU communicate with each other through an ARINC 429 data
bus using ARINC 429 words.
(b) When the SDU receives the standard ground test command containing its
equipment ID and source destination identifier (SDI), the SDU responds by
setting the command word (ARINC label 350) acknowledge bit to ACK for four
seconds. The SDU initiates a system-wide functional test. As soon as possible
during the execution of the functional test, the SDU sets the SSM for ARINC
label 350 to functional test.
(2) CMC to SDU Communication -- Automatic Fault Reporting
(a) The CMC and SDU communicate with each other through an ARINC 429 data
bus using ARINC 429 words.
(b) When the SDU receives the standard ground test command containing its
equipment ID and source destination identifier (SDI), the SDU responds by
setting the command word (ARINC label 350) acknowledge bit to ACK for 4
seconds. The SDU then initiates a system-wide functional test. As soon as
possible during the execution of the functional test, the SDU sets the SSM for
ARINC label 350 to functional test.
(c) At the conclusion of the functional test, the SDU builds the fault summary words
using ARINC labels 350 thru 354 by mapping currently active failures to the
appropriate bits in the words. Once the words are built they are latched for 30
seconds, then the SDU returns to automatic fault reporting. The SDU
continuously transmits the fault summary words to the CMC at a rate of 1 to 2
Hz, with the SSM bits set to normal operation during reporting of the test results.

(3) CMC Interactive Mode
(a) The SDU supports configuration data in CMC interactive mode for a Boeing 777
installation. If the CMC transmits a configuration data interactive mode command
addressed to the SDU on ARINC label 227, the SDU processes the command by
supplying the first page of configuration information and then resumes automatic
mode processing. The configuration data command is used to display
configuration information for the SATCOM LRUs (SDU and HPAs). The SDU
responds to the configuration data command from the automatic mode.
(b) The SDU does not support ground test and shop faults in CMC interactive mode.
If the CMC transmits a ground test or shop faults interactive mode command
addressed to the SDU on label 227, the SDU ignores the command.
(4) Configuration Data Messages
(a) General
When configuration data is commanded, the MCS configuration data
page(s) is(are) displayed. These data pages display installed LRUs as
determined by the SDU system configuration pin settings with their
associated part/serial number data. These lines also display the ORT
identification along with modification status. Figure 6-17 supplies an
example of the configuration data page.
The ORT 24-character description as contained in ORT item xxxiii is
displayed. For non-777 installations, the text is limited to 20 characters per
line.
(b) USER ORT STATUS
This displays MODIFIED if the state of the ORT user partition is modified,
otherwise no status or header is displayed.
(c) SECD ORT IDENTIFICATION
This is the 24-character description as contained in ORT item liii. For
non-777 installations, the text is limited to 20 characters per line.
(d) SECURED ORT STATUS
This displays MODIFIED if the state of the ORT secured partition is modified,
otherwise, no status or header is displayed. For software package C3.5, the
ORT is not partitioned so only a single ORT IDENTIFICATION is supplied for
the ORT display lines.

bbbbbbb-hhsss represents the LRU end item part number consisting of a
seven-digit LRU base part number (bbbbbbb), a two-digit hardware
configuration number (hh), and a three-digit software configuration number
(sss). Dashes are displayed if no valid data is available.
LRU SERIAL NUMBER
The serial numbers of the LRUs installed are displayed as follows. The word
LRU is displayed, which is substituted with the appropriate LRU acronym.
The LRU serial number is displayed as ssssssss, where ssssssss represents
the LRU serial number. Dashes are displayed if no valid data is available.

(g) SDU S/W PART NUMBER
This displays the software part number that corresponds to the software
load. The configuration data page includes the header SDU CONFIG
STRAPS and the raw strap setting for the current installation.
(5) Standard Ground Test (Non--interactive)
(a) When a standard test on a CMC ground test menu is selected, the CMC
commands the SDU to start a standard ground test. The SDU prevents the CMC
commanded standard ground test while the aircraft is airborne. The SDU starts a
system-wide PAST after it has responded to the receipt of a standard ground test
command from the CMC.
(b) At the end of the CMC-commanded PAST, the SDU builds labels 350 thru 354
fault summary words by mapping PAST-detected SATCOM subsystem failures to
the appropriate bits. The SDU continuously transmits these fault summary words
to the CMC at a rate of 1 to 2 Hz, with the SSM set to Normal Operation, during
reporting of the test results.
C. Airbus/Douglas CFDS
(1) General
(a) The CFDS uses a centralized fault display interface unit (CFDIU) as an interface
between the SDU and the SCDU. Throughout these paragraphs the acronym
CFDIU is used to include both the A320 CFDS and the A340 CMC.
(b) When the SDU is installed on an Airbus or McDonnell Douglas aircraft with a
CFDS, it supports the normal mode and interactive mode as required by the
CFDS.
(2) CFDIU to SDU Communication
(a) The CFDIU communicates with the SDU through an ARINC 429 data bus using
ARINC 429 words.
(3) SDU to CFDIU Communication
(a) The SDU supports both the normal mode and the interactive mode, as required
by the CFDS. The SDU also transmits the LRU part number and serial number
and ORT identification data blocks to the CFDIU.
(b) The LRU/ORT identification data records make up the LRU/ORT identification
data blocks. Each LRU data record contains the LRU acronym, part number, and
serial number. Each ORT identification data record contains the ORT
IDENTIFICATION header, the ORT 24 character description, and the state of the
modified flag.
(4) Normal Mode Failure Messages
(a) As specified, the SDU transmits failure messages and LRU/ORT identification
information while operating in the normal mode. The following paragraphs
defined the contents of these reports.

SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
MCS--4200/7200 Multi--Channel SATCOM System
(b) Once a failure is reported in the normal mode, the failure remains in the report
for that entire flight, regardless of whether the failure is cleared. As new failures
are reported, they are added to the beginning of the report (i.e., the report is in
reverse chronological order, bearing in mind the CFDS considers the time of the
failure to be the time it is first reported on this flight leg rather than when it first
occurs).
(c) In addition to latching the failures, the contents of the normal mode report
depend on the failure class and when it occurs in relationship to other failures
against the same LRU. Level I failures against the same LRU reported in the
normal mode are not to be transmitted more than once unless they are an upper
class and the upper class failure occurs after the lower class failure(s). Once a
report is sent to the CFDIU during the normal mode for the current flight, the
SDU does not change the content or order except to add new failure messages,
as appropriate to the beginning of the report.
(d) The McDonnell Douglas CFDIU does not decode the normal mode report until
the CFDIU detects an increase in the block word count. However, unlike the
Airbus CFDIU, the McDonnell Douglas CFDIU decodes the entire report. After
sending an All Call DC2 command for a new flight leg, the Airbus CFDIU delays
processing the normal mode report for about 30 seconds before regarding the
report as pertaining to the new flight leg.
(e) The SDU transmits the names of the installed LRUs, as determined by the
system configuration pin settings, along with their associated part/serial
numbers. At the end of this LRU transmission, the SDU transmits the ORT
identification with a modification status. The LRU names can be transmitted in
any order. Transmission of an HPA LRU part/serial number uses the same
criteria as the display of HPA data.
(5) Interactive Mode
(a) The CFDIU supplies for two-way communication between the SCDU and the
SDU, which is referred to as the interactive mode. When the SDU operates in the
interactive mode, it is responsible for all information displayed on the CFDS
maintenance pages, with exception of the scratchpad. The SDU enters the
interactive mode upon receiving an ENQ command from the CFDIU when the
aircraft is on the ground.
D. Central Aircraft Information and Maintenance System
(1) The central aircraft information and maintenance system (CAIMS) is a distributive
maintenance system where each member system performs its own built--in test (BIT)
and stores its own faults. Also, each system supplies real--time status information on
the health of each of its LRUs and their interfaces. The member systems support
CAIMS during normal operation and during on--ground maintenance.

SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
MCS--4200/7200 Multi--Channel SATCOM System
(2) In the normal operation mode, member systems gather and store fault data when
equipment failure occurs during normal operation. This is typically performed by
continuous BIT and power--up BIT, with identified faults stored in the member
systems non--volatile memory (NVM). The CAIMS does not store fault information for
member systems, but the fault warning processor (FWP) supplies fault event data,
such as: flight leg, date, time, fault zone, and aircraft serial number information that is
stored with the fault in the member systems NVM.
(3) In the maintenance mode, the CAIMS is active and is called the on--board
maintenance system (CAIMS OMS). The CAIMS OMS is the ground maintenance
function and is accessible through communication link to a portable maintenance
access terminal (PMAT). With the PMAT, the aircraft maintenance crew can retrieve
stored fault data from a member system. For member systems, the CAIMS OMS
displays fault information, commands BITE test, and displays real--time data for
status displays, and commands the download of NVM fault data.
E.
Level I Failure Messages and ATA Reference Numbers
(1) The Level I failure messages and ATA reference numbers that are available for
transmittal in the CFDS normal mode, for display in the CFDS interactive mode, and
for display on SCDU accessed maintenance pages are specified in the following
paragraphs for each CFDS type installed. Level I failure messages are intended for
use by line maintenance crews. Therefore, the failure messages are designed to be
LRU-based and only supply LRU-level identification.
(2) The Level 1 failure codes are two-digit hexadecimal numbers that define the LRU,
data communication bus, or miscellaneous interface signal where a failure, bus
inactivity, or signal error has been determined to have occurred. When multiple LRUs
are suspect, the most likely LRU is listed first followed by the next most likely LRU,
separated by a slash. The ATA number listed is for the first suspect LRU. Additional
text can be supplied at the end to help clarify the failure message.
• Table 6-18 describes the Level I failure messages and ATA reference numbers to
use for display on the SCDU accessed maintenance pages when the installed
CFDS type is a Boeing CMC. Also shown is the CMC message ID which is
displayed by the CMC in response to the Level I failure messages (refer to the
OEM’s maintenance manual and fault isolation manual).
• Table 6-19 and Table 6-20 describe the Level I failure messages and ATA
reference numbers to use for transmittal in the CFDS normal mode, and the CFDS
interactive mode pages displayed when the installed CFDS type is an Airbus.
Table 6-19 is for the SDU (single configuration) or SDU No. 1 (dual configuration),
and Table 6-20 is for SDU No. 2 (dual configuration) as determined by the settings
of configuration pins TP12E and TP12F.
• Table 6-21 describes the Level I failure messages and ATA reference numbers to
use for transmittal in the CFDS normal mode, and the CFDS interactive mode
pages displayed when the installed CFDS type is a McDonnell Douglas.
• For CFDS type none, the Level I failure messages displayed on the SCDU
accessed maintenance pages are the same as those specified for Boeing (refer to
Table 6-18). However, no ATA reference numbers are displayed.

(3) For Level I codes identified as not applicable in the tables, the SDU does not report
the failure on that particular interface (i.e., CFDS normal and interactive modes or
SCDU accessed maintenance pages as appropriate). Where TBD is used in the
Level I failure message column, it is coded as literally read. For failures that occur
that are undefined in the tables, the SDU does not report the failure on that particular
interface.
