5. Idetity and Security 5.1 Transceiver Labelling Introduction Each Motorola GSM transceiver will be labeled with various number configurations.The following information shows and explains the common labeling titles. Title Explanations MSN The Mechaniacal Serial Number(MSN) is an individual number, uniquely identifying the unit. The MSN will remain the same throughout the units life, even if the main board is replaced.
REV S/H This configuration consists of two blocks of two digits, and denotes the software and hardware versions within the unit. The first two digits correspond to the software version, and the last two digits correspond to the hardware version. If a version update is carried out on the unit, the correspongding change information should be made apparent on the labeling. Model The model number defines the type of product. Each product type is issued a common model number.
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 keypads, 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/supper PIN code must be entered.
6. Theory Of Operation 6.1GSM System Overview Note The following description is intended only as a preliminary general introduction to the Global System for Mobile communications (GSM) cellular network. This description is greatly simplified and does not illustrate the full operating capabilities, techniques, or technology incorporated in the system. 6.2General Cellular Concept The cellular systems are used to provide radiotelephone service in the frequency range 890-960MHz.
• • • • Digital Air Interface – The GSM phone will provide an entirely digital link between the telephone and the base station, which is, in turn, digitally linked into the switching subsystems and on into the PSTN. ISDN compatibility – ISDN is a digital communications standard that many countries are committed to implementing.. It is designed to carry digital voice and data over existing copper telephone cables. The GSM phone will be able to offer similar features to the ISDN telephone.
The radiotelephones themselves are capable of operation on any channel in the system, allowing them to operate in any cell. Due to the low power requirements for communications between radiotelephones in a particular cell and the cell site, operating channels may be repeated in cells which are outside the coverage area of each other.
The data blocks are modulated onto the carrier using Gaussian Mininum Shift Keying (GMSK), a very efficient method of phase modulation. Each time an information burst is transmitted, it may be transmitted on a different frequency. This process is known as frequency hopping. Frequency hopping reduces the effects of fading, and enhances the security and confidentiality of the link.
The radio telephone’s identity information is held by its lcal GSM system in its Home Location Register (HLR) and Visitor Location Register (VLR). The VLR contains identity informatino on all local active radio telephones. Should you roam to another area, system or country the radiotelephones identity information is sent to the VLR in the new system. The new system will then check the radio telephones details with your home system for authenticity.
7.Detailed description of Schematic Diagram 7.1 Transceiver The main chip for Taichi RF is MAGIC. The MAGIC IC is intended to support the needs of the GSM/DCS1800 portable telephone products. For Taichi the MAGIC IC will provide the first LO (RX VCO) to the receiver at 1325.2 to 1359.8 MHz for EGSM with 400 MHz high side injection, and 1405.2 to 1479.8 MHz for DCS 1800 with 400 MHz low side injection. An external RF mixer will convert the received signal to 400 MHz.
is then multiplied up in the reference oscillator step up loop to an output frequency of 13MHz. The reference oscillator will be within 150ppm of 26MHz within 100msec of the REG_REF input rising to 2.775V. The 13MHz reference will be provided externally for the logic sections as a CMOS output at 1Vp-p at CLK_OUT. At power up, the crystal oscillator divided by 2 will be routed to the CLK_OUT pin by pulling CLK_SEL low. An SPI bit is then used to activate the digital AFC.
MQSPI CS1 input Ball input CLK4 G5, CE DR1 output Ball output Ball output L8, P5, MQSPI CS1 DR1 DX1 (SPI_DATA): Serial Peripheral Interface Data, Data will be transmitted from WhiteCap to the MAGIC IC. Data will be latched into MAGIC either on rising edge or falling edge of clock depending on the control bit settings. MQSPI_CLK : Clock used to shift data out serially.

module which can give backlight in darkness environment. U9812 drives IR diodes for communication link between PC and DragonBall. Alert circuit is also controlled by DragonBall. Alert circuit is also controlled by DragonBall. Analog switches provide multiple communication path control which give the serial port different link under different use conditions. Refer to the PDA logic block diagram. 7. 3 Power Supplies Global Control Audio Power II ( GCAP-II ) is a power and audio management IC.
V1 is a programmable linear regulator. It is programmed through the SPI bus to either 5.0V or 2.775V. For Taichi V1 is programmed to 5.0V and is supplied by V_BOOST1. This regulator is on whenever the radio is turned on. V1 supplies the DSC bus. • V_BOOST1 Switcher Regulator V_BOOST1 is a switching regulator. At power up pins PMG0 and PMG1 determine the mode of the switcher. For Taichi V_BOOST1 is programmed to 5.6V because PMG0 is shorted to B+ and PMG1 is shorted to ground.
During charging the Whitecap will monitor the thermister line and the BATT Sense line through A/D convertor within GCAP-II. The thermister is inside the battery and indicates its temperature during charging. The temperature of the battery defines the end of battery charge cycle in some cases and must be monitored continuously during charging. The energy flows along the dashed wider line from EXT_B+ to BATT+ as above diagram indicated. 7. 5 LCD module 1.

There are three audio outputs provided by GCAP-II, Taichi used two for its application. One is for its earpiece speaker and another one is for external speaker audio output. For driving those audio output signals, one amplifier is connected with each of the three outputs. For those amplifiers: A1 is for transceiver earpiece speaker amplifier, A2 is for Alert amplifier and A4 is for External audio output amplifier.
microphone inputs can be selected. These inputs are EXT_MIC, the output of the differential input microphone amplifier, A3 or , the output of the differential auxiliarymicorphone amplifier, A5. These three inputs are single ended with respect to VAG. Note that MIC IN+ should be DC connected to VAG to avoid an offset relative to the A/D input. MIC_BIAS is derived from VAG for best noise performance. MB_CAP bypasses the gain from VAG to MIC_BIAS to keep the noise balanced.
at the same time as the Audio CODEC interrupt. An ARM interrupt is generated to synchronize the ARM megamodule to the DSC interrupt. The DSC time slots are the basic data structures in the DSC module. The function of the DSC is to transmit and receive DSC frames on the DSC bus. These frames may come from or be sent to the Lead DSP Audio Coder XIO port, the ARM Call Processor PIF port, or the Manchester coded DSC bus.
8. Personality Transfer 8. 1 Introduction Due to the different variations of the (OEM looks) of the personal cellular telephones, 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.
Step 12: When the third block of data has been transferred successfully,remobe the Transfer card and check the repaired radio functions correctly. See to the information in ‘Testing’. 8. 3 Master Transfer This method of transfer should only be followed when the defective unit will not power up, or complete a Normal Transfer.
information in the unit onto the Transfer card to create a Master Transfer card.? Step 3: 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 recipient units display. Step 4: A Master Transfer card has now been created.
9 TESTING GSM Verification Introduction To test the phone for functional verification,the following equipment is required. • GSM compatible communications analyzer. • Antenna test adaptor (Part Number SKN4870A) and an appropriate cable/connectors. • Test SIM card (Part Number8102430Z01). • Charged battery pack.
