1 GPRS (General Packet Radio Service)
GPRS 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.
Example: Cell with 1 Frequency channel:
1 physical channel for signaling, 4 physical channels for Circuit switched and 3 physical
channels for Packet switched.

6 Disassembly of AX75
Note: ESD concept; the internal circuits will be more susceptible to ESD because of
the use of exchangeable housing. The construction of the internal block must be/is
designed, in the best possible way, to protect the circuit against sparks.
The keypad must be completely closed to prevent any occurrence of an ESD
disruptive discharge.
The SIM contacts may be open, thus reachable for ESD contact discharge. This
could lead to damage or destruction of the E-Gold pins.
It is a requirement for the service personnel to observe ESD protection rules while
performing servicing the AX75.

7 Reassembly of AX75
For the reassembly of the AX75, reverse the disassembly procedures from Step 12 to
Step1. However there are some areas to be taken note of during reassembling of the
phone.
During the installation of the SIM card, make sure that the SIM card is inserted properly and
that the golden contact area is facing downwards. Insert the SIM card downwards to lock the
SIM card into position.
Installation of the SIM card
During the installation of the battery, make sure that the hinges are properly in place (See picture
below). Otherwise the battery will not be able to fit into the phone properly.
When placing the screws, set Torque to 17cNm.

8 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, and
short dial list etc., required by the operator or service provider. Therefore, it is common 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 fulfil 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
Usage of GRT is mandatory!! For more detail check GRT User manual

8.1 Mobile Software Updating
The software of the 75 series mobiles, is loaded from a PC directly. Hardware
interconnection between the mobile and the PC is shown in Figure 1. Because of the new
type of external connector used since 55 series (Slim-Lumberg type) an additional
adaptor cable between mobile and boot adaptor is required. Table 1 listed all the
hardware requirements
If you use the battery dummy, make sure that the power supply voltage is correctly
adjusted.

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:
Siemens Mobile Service Equipment
All mobile Phones have to be tested with the GRT-Software.
The Service Partner is responsible to ensure that all required hardware is
available.
For additional Software and Hardware options as well as the supported GRT
equipment, please check the GRT User manual
