XT55 / XT56 Siemens Cellular Engines
1 Preamble
This Release Note describes the XT55 / XT56 Release 03.03. The document briefly
summarizes all new features and major changes which have been added since
Release 02.06.
To meet the legal demands according to the Directive 2002/95/EC (RoHS) the hardware
platform of XT55 / XT56 modules has been changed with this release. Along with this
change, the SIM interface was optimized for electrical testing on the ORGA IT3 platform
according to the “3GPP TS 51.010-1” specifications. The general performance regarding
compliance with GSM Standards remains unchanged.
Please note that XT55 / XT56 Release 03.03 and all later releases cannot be loaded into
XT55 / XT56 modules based on previous hardware releases. Likewise, older firmware (up to
Release 02.50) cannot be loaded into the new hardware platform.

3.2 Improvements over Interim Release 02.50
This chapter applies only to the Internet Service AT commands and provides a list of latest
changes.
AT command / Feature
New connection profile
features
Brief description
The Internet services Socket, HTTP, FTP, POP3 and SMTP can now be
used over GPRS and CSD (circuit switched data). The bearer type can be
selected with AT^SICS, parameter <conParmValue_conType>.
AT^SICS includes the parameter <inactTO>. This is an inactivity timeout
that specifies the number of seconds the bearer remains open although
the service no longer needs the bearer connection.
XT55 / XT56 modules now support the authentication methods PAP
(Password Authentication Protocol), CHAP (Handshake Authentication
Protocol) or none. The method actually used for an Internet connection via
CSD or GPRS is negotiated at the LCP layer, i.e. it is negotiated with the
remote peer at connection setup.
Socket Listener
If a Socket connection request is successfully accepted with AT^SISO the
expected “^SISW” URC will be correctly issued to notify the host that
writing data is possible.
Socket connection with
parameter “size”
When a Socket connection configured for a fix data size is closed and the
next Socket connection shall use a variable data size (0), it is now
possible to open the same service profile and simply change the
parameter “size”. This eliminates the need to create a new service profile.
HTTP
The handling of redirected HTTP pages has been consolidated.
The problem of indicating HTTP service states has been fixed. The
AT^SISO read command can now display all possible service states
specified in [1].
FTP download / upload
Timing problems during FTP transfer have been fixed. It is no longer
necessary to manage the transfer of an announced data package within
40 seconds.
AT^SISS
Setting the parameter “srvtype” no longer resets the parameter “alphabet”
to “0”.
Timeout in case of poor
network coverage
If Internet service commands are used while network coverage is
insufficient the module no longer tries to execute the command for an
indefinite time, but delivers, after a 2 minute timeout, the result code
“+CME ERROR: network is down”.
