Introduction
The document is intended to help you carry out repair up to Level 2 on the S35i series mobile
phone.
The repair for international version and Asian variants are identical unless otherwise noted,
therefore the description herein is confined to S35i only.
The S35i electrical design is similar to the C35 mobile phone – they use same PCB and
electronics component for majority of the circuit. For testing and the accessories for the S35i
please refer to the C35 service manual.
All repairs have to be carried out in an environment set up
according to ESD regulations defined in international standards.

General Information
Due to different requirements of the markets, the S35i has different variants, which broadly
classified under International version and Asian version. Marketing name for international
version is S35i, whereas Asian version is named 3568i.
The different for ASIAN version is only mobile software.
The 3568i is equipped with a graphic display which enable the telephone to display
CHINESE characters, either in Traditional font or Simplified font, beside the standard
English.
Wireless Application Protocol, WAP.
Wireless Application Protocol takes a client-server approach that uses the in-built microbrowser to make a request, in wireless markup language (WML), for information or
service. The request is passed to a WAP Gateway which then retrieves the information
from a Internet server, in HTML format, and translate it into WML. The requested
information is then sent to from the WAP Gateway to WAP client (mobile) using the
available and most appropriate mobile network bearer services.
Wireless Protocol Stack.
Wireless Application Environment (WAE)
Wireless Session Protocol (WSP)
Wireless Transaction Protocol (WTP)
Wireless Transport Layer Security (WTLS)
Wireless Datagram Protocol (WDP)
Bearers e.g. Data, SMS, USSD
TABLE 1..1 WAP PROTOCOL STACK
1. Wireless Application Environment
Defines the user interface on the phone. WAE contains the WML,WML script and the
wireless telephony application (WTA).
2. Wireless Session Protocol
Link the WAE to two session services – one connection oriented operating above the
WTP and a connectionless service operating above WDP.
3. Wireless Transaction Protocol
Runs on top of the datagram service and part of the standard suite of TCP/IP
protocols, to provide a simplified protocol suitable for low bandwidth mobile station.
4. Wireless Transport Layer Security
WTLS incorporates security features that are based upon the established Transport
layer Security (TLS) protocol standard, that include data integrity checks, privacy on
the WAP Gateway to client leg and authentication.

5. Wireless Datagram Protocol
Allows WAP to be bearer independent by adapting the transport layer of the
underlaying bearer. WDP presents a consistent data format to the higher layer of the
WAP stack.
