Private Communication Systems Mobile Phones 5.2 Hardware Description The handset consists of five major integrated circuits: 1) HiGOLD (PMB 2800) This IC is a combination of microprocessor and signalprocessor. The microprocessor is responsible for controlling the keyboard, SIM-Card, EEPROM, Flash and RAM. Furthermore it controls the power up/power down of the RF module and sets the amplification of the PA.
Private Communication Systems Mobile Phones The C1x has two main power inputs (see Blockdiagram): 1) Battery Voltage (3.6 Volts) connected at the battery contacts 2) Charging Voltage (6.5 Volts) delivered by a) The plug-in charger at the charging plug b) The car kit through the charging connection at the Molex connector c) The desktop charger through the contacts at the outer ends of the Molex connector. Since the battery voltage is supplying the power supply asic, it is always needed to operate the phone.
Private Communication Systems Mobile Phones Furthermore the ASIC generates the supply voltage for the SIM-Card and the RESET signal for the logic devices. The ASIC also checks the presence of the watchdog signal from the µP and provides the switching on functionality (ON_OFF button or Ignition signal). During testing ist is advisable to use a battery dummy, connected to a power supply delivering +4V, max 3A.
Private Communication Systems Mobile Phones 6 Software programming The software of the C1x handset is programmed directly from a PC using a bootadapter as an interface beetween serial port of the PC and the mobile. 6.1 Description of software booting Connect COM-port of PC to the bootadapter using the enclosed RS232 cable. ˆ Afterwards plug in AC-Adapter: If connected correctly the “Power” lamp will be active. Switch off the C1x handset and connect it to the 9 boot adapter.
Private Communication Systems Mobile Phones 7 Battery 7.1 Specification The C1x battery is a NiMH type with a voltage of 3.6 Volts and a capacity of 700 mAh. Suppliers are Varta and Maxell. You can easily recognize the manufacturer by the colour of the battery cells: Varta’s cells are of a green colour, Maxell’s ones are bluish. The connections BATT+ and GND are used to supply the mobile.
Private Communication Systems Mobile Phones 7.2 Charging The battery can only be charged if inserted into the telephone. The charging process is completely controlled by the mobile.
Private Communication Systems Mobile Phones 7.4 Deep Discharge In case of a deeply discharged battery, the phone can not be turned on and the normal charging process can not be started. In this case, charging the battery is divided into two different steps, which have to be run subsequently: a) Trickle charge Trickle charge mode is automatically started if the battery voltage is below a certain value when the charger is connected to the mobile.
Private Communication Systems Mobile Phones 7.5 Battery Datecodes There are two different suppliers of the C1x batteries and they use different kinds of codes to give information about production date: a) Maxell batteries The datecode printed on the battery looks like this: K 7 08 20 M Explanation: K 7 08 20 M = Year of production (1998=K, 1999=L) = Month of production (Jan=1, Feb=2, .....Oct=O, Nov=N, Dec=D) = Day of production (1st =1, 2nd =2, 3rd =3,........
Private Communication Systems Mobile Phones 8 Unblocking If the phone is disabled due to a wrong entry of the phonecode (not PIN1, PIN2, network code or service provider code!) it can only be resetted by entering the right unblocking code. This unblocking code is derived from the IMEI number of the mobile and can only be calculated in two different ways: 8.1 Siemens Hotline You can retreive the code from our hotline personell in Germany.
Private Communication Systems Mobile Phones 8.2 Internet solution As an alternative to the a.m. procedure, since november 1997 an internet solution is offered to the LSO. It is a password protected internet homepage where you can enter the IMEI number of the affected handset. The page will then present Master Phone Codes, Master Network Codes and Master Service Provider Codes (if applicable to the relevant telephone).
