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.

7 Disassembly of M75

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 S-Goldlite pins.

It is a requirement for the service personnel to observe ESD protection rules while performing servicing the M75.

10 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

10.1 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.
