9.2 Additional MMTI Troubleshoot Information
This section provides additional tests that may be used for troubleshooting or system check-out. Tests in
this section require the use of the MMTI commanded mode screens. See section 9.3 for information
detailing navigation and description of the various MMTI commanded mode screens.

9.2.1 Data Cable Pull Check
The data cable pull check can be a useful test for finding intermittent cable connections between CDBRs or
between a CDBR and an ARTU. This test is performed using the MMTI commanded ~e. This test
involves monitoring debug messages on one of the MMTI status screens while moving the data cables.
The performance of this test requires the ARTU to be placed in a "locked offline state" in order to easily
rcvicw thc MMTI debug messages. While in the "locked offline state" the "71 P AB_BIT TASK" dcbug
screen will display a message if the ARTU detects an intermittent connection. The MMTI will display
"AMX_IN_SYNC message received from AMX DSP LAN Adr=xx" on the debug screen if an intermittent
connection is detected as shown in Figure 9.2.1. The message "DQ2 DSP _ERROR_CODE rcvd from DSP

#14, HDRI=I00 hex" message will appear every 15 seconds on the debug screen when the ARTU is placed

in the proper mode and the correct debug screen selected. If an intermittent connection is detected, check
the cable for proper seating, damage, and bad or broken solder joints. Swapping of a CDBR or AIU may
be necessary to isolate intermittent or damaged connectors on the units themselves. The steps for
perfonning the data cable pull check are as follows:

Power up the ARTU and let it complete Built-ln- Test.
Connect the MMT cable to the ARTU and the computer.
Start the MMTI software and select commanded mode of operation.
Select the Goto Radio Installation/f est Menu.
Select the Set Radio Locked/Offline command.
Press the escape key.
Goto Radio Maintenance Operations Menus.
Goto Debug Menu.
EnablelDisable All Debug Msgs.
Enable All Debug Msgs.
Select No to Log Debug messages.
Press the "F I" key three times to scroll to the 71 P AB_BIT TASK Debug screen.
The message "DQ2 DSP_ERROR_CODE rcvd from DSP#14, HDRI=IOOhex" message will

appear every 15 seconds on the debug screen.

Move cables and look for intermittent connections on the MMTI Debug screen.

9.2.4 L-Band Interference Tests
Because the C-2000 system operates in the 850.900 MHz range, interference between the C.2000 and L-

Band equipment (i.e. DME, Transponder, TCAS) can occur if there is not enough isolation between
antennas. Testing for interference can be done by making the C-2000 equipment transmit. By monitoring
the Receiver Signal Strength (RSS) value reported in the Radio Status screen while the ARTU is
transmitting, it can be determined if the L-Band equipment interferes with the C-2000 system.

The simplest test method is to use the MMTI installation test mode and to stop at the Receive Signal
Strength test step. By not connecting up the loop around test box, no signal level should be reported above
the nominal no signal value. Frequency agile devices like DMEs must be tuned and transmit across the
whole operating frequency range to assure that there are no frequency dependent interference problems. If
any change occurs in the RSS value then there is interference from external equipment. The nominal no
signal value of the RSS can be determined by disconnecting the receive coax cable from the ARTU and
viewing the RSS value on the Radio Status screen. See section 6.3.12 for the Receive Signal Strength
Measurement test procedure.

9.2.5 CEPT -El Communication Verification
The MagnaStar ARTU is capable of interfacing to multichannellNMARSA T SA TCOM equipment using a

CEPT -EI digital interface. ARTU part number 724855-802 has additional hardware which will support
this interface. Calls are routed through the ARTU to the SA TCOM over the CEPT -E I interface. The
CEPT -E I interface is a 2.048 MHz time division multiplexed data bus consisting of differential serial
transmit and receive lines.

Communication between the ARTU and the SA TCOM equipment can be verified by viewing a MagnaStar
digital handset. If a handset displays the word Satcom on the Services menu when the handset is on hook.
or in the bezel, then the ARTU and SA TCOM equipment are in communication over the CEPT -E I
interface. Also, if the LINK option is available from the handset Main menu, then the CEPT-EI is
operational. If SA TCOM is not present at the Services menu, then the SA TCOM system has informed the
MagnaStar system there are no channels available. If this happens during initial system installation, verify
the Satcom system configuration jumpers (verify that the SA TCOM system has been configured for
External CTU). It is possible that conditions may exist which will keep SA TCOM calls from being placed
SA TCOM units do provided status information to the ARTU over the CEPT -E I bus which can indicate that
the SA TCOM unit is either faulted or that SA TCOM channels are not available for use. This information is
reported to the user when a call is placed. SA TCOM channels not being available for use may include
items beyond the SA TCOM unit including satellite coverage problems or ground station problems.

It is possible to detennine the status of the CEPT -EI interface between the ARTU and the SATCOM unit
using the MMT. Figure 9.2.5 shows the ARTU Status screen. In the lower right hand comer is CEPT -EI
status information. The CEPT -EI status information has three possible states; RR, RNR and DOWN.
There are two columns of information. The ARTU column applies to the ARTU and the CMS column
applies to the SA TCOM equipment. It may be possible to isolated RNR problems to a particular piece of
equipment using the column labels.

RR-

RNR - This status information means Receive Not Ready. This condition indicates that the

DOWN - This status information means that the CEPT -El interface is not operational. This could

indicated that either piece of equipment is at fault or no CEPT -E 1 connection.
