LABELLING AND SIM CARDS

SIM CARDS

1.

INTRODUCTION

The Motorola StarTAC130 personal cellular telephones are designed to work with the mini Subscriber Identity Module

(SIM). The SIM card contains all the personal data required to access GSM services. Data held by the SIM card includes:-

• International Mobile Subscriber Identity

• Temporary Mobile Subscriber Identity

• Home system

• Services subscribed to

• PIN and unblocking codes

• Call barring codes

The SIM card may also be capable of storing phone numbers, names, and messages.

2.

SIM CARD INSERTION/REMOVAL

The SIM card must be inserted into the unit correctly so that the card can be read, and the data checked for validity, before operation on the system will be enabled. The card contains all of the user’s personal identification numbers and details of the system the phone operates on. side of the phone.. To remove the SIM card from the unit, pull the sliding mini SIM tray sideways away from the phone. The User Guide contains full information about inserting and removing the mini SIM card.

3.

SECURITY INFORMATION

To stop unauthorized personnel using your SIM card, the option of using a Personal Identity Number (PIN) is available. When enabled the option requires (on power up) a verification number to be entered via the unit’s keypad, before the card can be used. Three attempts to enter the correct PIN may be made. If after the three entries the correct

PIN has not been entered, the card becomes blocked. To unblock the card an unblocking/super PIN code must be entered. Ten attempts to enter the correct unblocking code are permitted, if after ten attempts the correct code has not been entered, the SIM card is corrupted and becomes useless.

Another option available for the SIM card is call barring. If subscribed to, the call barring of incoming and/or outgoing calls may be accomplished by entering a special key sequence. The key sequence includes a “barring code”, which determines the type of restriction incorporated, and a password to validate the request. The initial password is provided when you subscribe to the service. The password can be changed by entering a set key sequence.

A valid miniature sized SIM card can be used in any working

GSM transceiver, regardless of the manufacturer, which is compatible with the miniature size SIM card. To protect the actual unit from unauthorized use, a lock function on the hardware is available. When enabled, this function requires that a three or four digit unlock code be entered, via the unit’s keypad, before normal operation of the transceiver can take place. The lock code can be changed by entering a set key sequence.

Note: Further information on set key sequences can be derived from the unit’s user guide.

TESTING PROCEDURE

All information required to perform the desired tests and measurements should be obtained from the communication analyser’s user manual.

Ensure that the unit being tested is capable of both initiating a call to the analyser, and receiving a call from the analyser.

Confirm that the displayed Temporary Mobile Subscriber Identity (TMSI), International Mobile Equipment Identity (IMEI), and dialled number are correct. When a call is in progress the following tests should be carried out on channels 1, 62 and

124. The recorded results must be within the acceptable stated limits, if the unit being tested passes all the tests it should be taken as functioning correctly. If the unit being tested fails to conform with any of the expected measurements, it should be taken as faulty and repaired accordingly. The following table states the required tests and tolerances.

PERSONALITY TRANSFER

PERSONALITY TRANSFER

1.

INTRODUCTION

Personality Transfers are required when a phone is Express

Exchanged or when the main board is replaced. The different variations (languages, features) of the StarTAC130 personal cellular telephones requires that each main board must be configured correctly to ensure that the unit takes on the correct personality required. Therefore, when a main board is replaced its personality must be transferred into the new board, so that it functions correctly in the customers unit. There are two possible methods of transfer.

• Normal Transfer, and;

• Master Transfer

If the defective unit powers up, then the Normal Transfer method should be followed. If the faulty unit will not power up, then a Master transfer will be required to configure the replacement board, once installed.

2. NORMAL TRANSFER

This method allows the personality, selected features and stored phone numbers of a defective radio, to be transferred into a repaired radio. Data is transferred from the donor unit into the recipient unit using a Transfer card (Part No

5104025D03). The instruction steps should be followed in order.

Step 1.

Step 2.

Insert the Transfer card into the slot located on the back of the donor unit. Turn the donor unit on, the display should show ‘Clone’.

The donor unit is now in the cloning mode, and ready to transfer the first block of data.

Step 3.

Enter 021# via the unit’s keypad. This command will cause the first block of information to be uploaded into the Transfer card.

Step 4.

Step 5.

Step 6.

Step 7.

Step 8.

Step 9.

While data transfer is taking place between the unit and the card, ‘Please Wait’ will be displayed. After a short period of time, if the data transfer has been completed correctly,

‘Clone’ will re-appear in the donor unit’s display.

When the first data block has been successfully uploaded, remove the card from the donor.

Insert the Transfer card into the slot located on the back of the recipient unit. Turn the recipient unit on, the display should show ‘Clone’.

The recipient unit is now in the cloning mode, and ready to receive the first block of data.

Enter 03# via the unit’s keypad. This command will cause the recipient unit to download the first data block from the Transfer card.

While data transfer is taking place between the card and the unit, ‘Please Wait’ will be displayed. After a short period of time, if the data transfer has been completed correctly,

‘Clone’ will re-appear in the recipient unit’s display.

Step 10.

The second data block must now be transferred.

Repeat steps 1 to 9, but enter 022# to program the second data block into the Transfer card.

Step 11.

The third data block must now be transferred.

Repeat steps 1 to 9, but enter 025# to program the third data block into the Transfer card.

Step 12.

When the third block of data has been transferred successfully, remove the Transfer card and check the repaired radio functions correctly. See page 19 for further information.


2/3/99

3.

MASTER TRANSFER

This method of transfer should only be followed when the defective unit will not power up, or complete a Normal

Transfer. As mentioned earlier, there may be different variations (OEM looks for example) of the Motorola

StarTAC130 cellular telephone, each model requiring the main board to be configured differently for correct operation. When carrying out a Master Transfer it is not possible to transfer the customers selected features or stored phone numbers, only the model personality can be programmed into the repaired unit.

Each different version of the StarTAC130 cellular telephone, requires its own Master Transfer card which contains essential set up information. Master SIM cards may be ordered pre-programmed, or created from a Normal

Transfer card. The instruction steps should be followed in order.

Step 1.

Step 2.

Select the required Master SIM card.

Insert the Master Transfer card into the slot located on the back of the repaired unit. Turn the unit on, the display should show ‘Clone’.

Step 3.

Step 4.

Step 5.

Enter 03# via the unit’s keypad. This command will cause the configuration data to be downloaded from the Master Transfer card.

While data transfer is taking place between the card and the unit ‘Please Wait’ will be displayed. After a short period of time, if the data transfer has been completed correctly,


When the data block has been transferred successfully, remove the Master Transfer card and check the radio functions correctly. See page 18 for details.

At no point should either 021#, 022# or 025# be entered while a Master Transfer card is in the radio. If either of the stated commands are entered, the master information on the card will be erased. To prevent the above happening the card can be locked by entering 06# via the unit’s keypad, with the card inserted. Unlock the card by entering 07#.

Note: If during either transfer process a problem arises, an error message will be displayed. If the Transfer card is removed before the data transfer is completed

‘Bad Data on Card’ will appear in the display. If either situation arises, the process should be repeated.

4.

MASTER SIM CARD CREATION

When required a Master SIM card can be created by:-

Step 1.

Insert a Transfer card into a unit which is already configured in the desired way. Turn the unit on, the display should show ‘Clone’.

Step 2.

Step 3.

Step 4.

Enter 024# via the unit’s keypad. This command copies the personality information in the unit onto the Transfer card to create a Master

Transfer card.

While data transfer is taking place between the unit and the card ‘Please Wait’ will be displayed. After a short period of time, if the data transfer has been completed correctly,


A Master Transfer card has now been created.

Lock the card to prevent accidental information erasure (see previous section). Remove the card from the unit, and store until required.

(see page 33) no

During initial radio power-up the SMOC IC performs power on self test diagnostic to confirm that the

HW is operational.

If any of the diagnostic tests fail, an error code will be sent in the first reply message sent to call processor.

Check in order the following signals :

MDM_WR,SPI CLK, SPI MOSI(micro DCA problem)

MDM_RD, SPI CLK, SPI MISO( SMOC problem).

(See the example in attached on page 33) yes

1) If all the above looks good, and the PCB is still not turning on, try to resolder U702,U704,U705 with ERSA station, if the PCB turns on, then shut down, go to immediately in test mode to read the error code and subcode.

2) Try to lift the EEPROM U705 and check if the PCB

(pwr up) communicate with emmibox.

If so, you read the internal info(sw,modem, speech) from the RAM with GMSKEY.

(e.i. If the error code is 7100#02=Ext ram error,there were some dry joint at Sram pins )

RESET SEQUENCE AT POWER ON

The power up RESET sequence is described in the following diagram. Following the activation of the

+2.75V Regulator, the GCAP LITE IC and the 68338 begin a seven state power sequence involving the

*RESET line and the GCAP Lite’s Watchdog input. The figure below depicts the sequence of the states.

The figure is not drawn to scale.

State 1

When the GCAP LITE IC detects a power on request (ON/OFF Line ”LOW”), the GCAP LITE will drive the system *RESET line low. The 68338 Clock line will take approximately 100mS to stabilize after power is applied.

State 2

The 68338, SMoC, and BIC in the radio are connected to the *RESET line. The nominal time *RESET is held low by the GCAP LITE is 250 milliseconds +/- 50 ms.

State 3

When the GCAP LITE releases *RESET, it is pulled high by an internal resistor. There isa period of approximately 500 nanoseconds when neither the GCAP LITE or 68338 is asserting *RESET.

State 4

When the 68338 reset control logic detects that the system *RESET line is no longer being driven, it drives it low for an additional 512 cycles (39.6 microseconds). This assertion of *RESET by the 68338 is a feature of the IC and cannot be modified.

State 5

When the 68338 releases *RESET, it is pulled high by the internal resistor. The 68338 be-gins executing its

Boot Code. If valid code is present, the RESET vector in the radio code is then executed. The Boot Code runs for about 512 cycles (39.6usec) before this new vector is executed.

State 6

The 68338 holds *RESET low for 50usec during this state (an internally generated RE-SET).

State 7

When the 68338 releases *RESET, it is again pulled high by the internal resistor. All the processors in the system, including the 68338, then begin execution. During this state, the 68338 must drive the GCAP Lite’s

- Check that there is B+ present at input to FCAP on pin 40. If not, could be problem with Battery Charger Circuitry (Q901)

- FCAP should then drive R275, L275 and VRef. If these are not present, could be a problem with FCAP itself.

- Verify collectors of regulators Q221 and Q222 are both around 2.75V.

- If ok, then check that the SMOC drives he Xtal Varactor Diode CR201 on the AFC line with a DC Voltage.

- If ok, then follow 13MHz path through GIF SYN & BIC and then to uP and SMOC.

- If ok, then check chip enables on Eprom, and SRams.

- If ok, then verify Reset Line.

.)

If the 215 is OK then we can assume problem lies around GIF, either 430MHz Local Oscillator or in generation of RXI and RXQ . The peel off can

SH202 should then be removed. Check that IQ Ref from the SMOC is around 1.38Vdc and then the RXI and Q outputs from the GIF to check which is faulty. Before actually removing any cans it may be worth checking the RX_EN and RX275 d f

- If, as in most cases the 215Mhz is low there is no choice but to remove the LNA/MIXER can ( SH402) and probe the R.F inputs to the Mixer to see which RF path (947.4 or 732,.4) the fault lies on.

- If 732.4 is low , and 947.4 is OK, the main suspicions are with the main VCO and this can should be removed ( SH201)

- If 947.4 is low , and the 732.4 OK, the main suspicions are with the input filter FL452 and this can ( SH402) should be removed, and if low at the input to these, it could be losses caused by the Rf Switch (U401).

- If 947.4 and 732.4 RF values are fine but 215MHz into GIF is low b

(FL420) and IF Pre AMP (Q421) is located under here.

which of the signals are missing or if both the signals are missing.

- If 170 is missing and 732.4 is fine then remove SH 202 and check for the 340 Mhz at GIF SYN.

- If we have no 340 and therefore no 170 then could be CR203 or GIFSYN problem. Check Q202 and Q203 have both 2.7V. If still no problems found, remove SH301 & measure DM_CS on U300 Pin7. Could also be SMOC problem.

- If 340 is ok but 170 not , remove SH301 and look for problems around U300. Could be problems with TIC,

.

GIF SYN or SMOC.

If 732.4 is missing but 170 is fine remove SH201 and look for faults. Could be a problem with CR250, GIF SYN or SMOC. Check collectors of Q202 and Q203 for 2.7V.

- If both 732.4 and 170 are missing then check the collectors of Q202 and Q203 for 2.7V. If ok, then remove

SH301 and probe DM_CS on pin 7 of U300. Possible GIF SYN or SMOC problem.

If 902.4 is generated but is low then we look for problems under SH301 and SH302 and follow path through to antenna

.

If 902.4 looks OK but fails in wingate check at the T/R switching circuitry (Q442, Q443, U401 ) switching RF to J600 or with the J600 connector itself. Use rf lead connected to J600
