ADSL Modem control software
The

transceiver
programmable DMT modem (ST70135A) whose
configuration is loaded by an external controller.

Software Architecture
is
based
on
a
Additionally to the control functions, STMicro-
electronics provides the DMT modem software.
The software is written in C++ language, and is
designed to be portable to any processor.
The driver has to be interfaced with a real time OS
kernel, it is compatible with any standard product
available on the market. The kernel manages the
tasks dedicated to modem software.
The modem Software core comes with two
software modules: Board Support Package (BSP)
and Application Programming Interface (API).
BSP manages the hardware dependent features
(i.e. interrupts, peripheral mapping).
APIs interface to the higher level application
software and to the OS.
ADSL Loop performances
The hereafter tables show the performances that
a system, which houses ASCOT, can achieve for
ANSI and ETSI loops. The following results refer
to an end-to end ADSL equipment with no
external disturbance.
