1 GPRS (GENERAL PACKET RADIO SERVICE)
G
PRS is a new non-voice value added services that allows information to be sent and received across a GSM mobile telephone network. It supplements today's Circuit Switched Data (CSD) and Short Message Services (SMS). GPRS involves overlaying a packet based air interface on the existing circuit switched GSM network. This gives the option to use a packet-based data service. The information is split into separated but related "packets" before being transmitted and reassembled at the receiving end. Theoretically, maximum speeds of up to 171.2 kilobits per second (kbps) are achievable with GPRS using all eight timeslots at the same time. This is about 3 times as fast as the data transmission speed possible over today's fixed telecommunications networks and 10 times as fast as current Circuit Switched Data services on GSM networks.
Figure1. Example of GPRS data transmission Example: Cell with 1 Frequency channel: 1 physical channel for signalling, 4 physical channels for Circuit switched and 3 physical channels for Packet switched

7.3 PCB top-side
7.4 PCB bottom-side
The C55/2128 assembly concept differs from the previous models (P35 & K45 series) slightly. The C55/2128 is no longer employing the concept of "No Screws". Instead of the previous upper & lower mounting frame to hold the PCB and the housing together, the C55/2128 uses six screws to hold the light guide, PCB and the mounting frame together. As seen from the mechanical diagram, the C55/2128 also uses two other different techniques from the previous models (P35 & K45 series). (1) The use of a light guide on the front panel to disperse the light evenly throughout the keypad & display area. (2) The use of a metal dome foil as keypad contact as opposed to the carbon/metallic contact keypads used in the P35 & K45 series.

9 REASSEMBLY OF C55/2128
For the reassembly of the C55/2128, simply reverse the disassembly procedures from Step 13 to Step 1. However there are some things to note on the reassembly of the phone. During the installation of the SIM card, ensure that the SIM card is properly locked in. If not, it would result in card error, as the SIM card will not be properly held in place.
Ensure that the SIM card is fully inserted and that the metallic lock is pulled down. During the installation of the battery, ensure that the hinges are properly in place. Otherwise the battery will not be able to fit into the phone properly.
Ensure that the hinges are properly fitted before fixing in the battery.

11 MOBILE SOFTWARE PROGRAMMING
The common mobile software available is divided into language groups. However, this software does not contain the specific settings, such as ringing tones, greeting text, short dial list etc., required by the operator(s) or service provider(s). Therefore, it is not uncommon to have some menu item(s) differ in different variants or are not visible at all. These settings are stored in different memory area of the mobile and will be activated depending on the customer specific model or variant of the phone by a separate test step during the production process. Due to this separation of common mobile software and customer specific initialization, it is possible to fulfill the demands of the market requiring customization and flexibility. As a consequence the software programming process in the LSO is divided into two different steps as followed: - Software update to actual version and appropriate language group - Programming of CUSTOMER SPECIFIC INITIALIZATION

12 SIEMENS SERVICE EQUIPMENT USER MANUAL
12.1 Introduction
Every LSO repairing Siemens handset must ensure that the quality standards are observed. Siemens has developed an automatic testing system that will perform all necessary measurements. This testing system is known as:
12.2 Siemens Mobile Service Equipment
Using this system vastly simplifies the repair of the phones and will make sure that: 1. All possible faults are detected 2. Sets, which pass the test, will be good enough to return to customer. Starting from the P35 Series, Siemens will introduce a simpler and faster testing platform for testing a repaired Siemens mobile phone. The testing platforms are either base on R&S CMD 53/55 or CTS55 GSM test set. There is also test software under development for testing with the Wavetek 4201S and the 4107 GSM test set. A Level 2.5 service software is also under development for more elaborate testing for the repair for the P35 series mobile phone.
THE LSO WILL HAVE TO PURCHASE THE SYSTEM, CHOOSING BETWEEN THE COMPLETE PACKAGE OR SUB-SET OF IT. A FULLY AUTOMATIC TEST PROCEDURE IS ONLY POSSIBLE IF THE COMPLETE SYSTEM IS INSTALLED.
Make sure that your CTS firmware is Version 3.01 or higher. For CMD 55 it must be Version 4.03 and higher. Please check with the Service Info SB_0500 for the CTS/CMD Hardware Options.

12.4 Software Installation
Before executing the test software, it is important to ensure that the software configuration matches that of the hardware set up. Each GSM Tester will have specific test software. The test software is named CMD_GO, CTS_GO and for Wavetek test set, CAT4200 respectively. First, copy the installation software for the specific GSM tester to a temporary directory on the harddisk of the Window PC and then Run the Setup from the first sub directory Disk1 for CMD_GO test software. After the installation for the test software, RUN the Test software and check the configuration setting for the Serial port.
