Motivation
The "Software" chapter includes a detailed descriptions of the software interfaces that are provided with the TC1
system. The operating system of the TC1 is a embedded GNU/Linux, which is is configured by STW.
To check for the latest version of the operating system for the TC1 go to the STW FTP server: ftp://stw-
connectivity.net/ (see ftp://stw-connectivity.net/ -
ftp://stw-connectivity.net/ )
The operating system is separated in two spaces:

kernel space

user space.
The user space is created by the root file system. The user space provides interface files that are generated by
the kernel. These files are not all human readable and are more system helpers (applications and scripts).
Thus, not all user space interfaces are inevitably described by the "Software" chapter. It was decided to
categorize the different user space interfaces into levels.
The following levels are defined:

Teleservice Application Framework: This level includes the TAF Library, which is written in C and can be
used by the user to create teleservice applications, and the TAF Components. This includes the teleservice
daemons and their configuration files.

High Level Hardware Access: This level includes scripted files (scripts) and tools (system helpers) which
provide more complex functionalities. It uses the Low Level Interfaces to process functionalities, e.g. mount
a device.

Low Level Hardware Access: This level includes files (interfaces) which are created by the specific drivers
from the kernel. These files provide information about the driver status, read / write values to the driver, etc.
6.1 System Information

package (BSP) of the TC1.
The BSP consists of the components:
