7. UPGRADING THE INTERNAL SOFTWARE (FIRMWARE UPGRADE):
This section describes the procedure to upgrade the
AEQ TLE-02D
Audiocodec internal software.
7.1. System description
The system allows the internal software in the three basic TLE-02D modules to be upgraded,
i.e. the Microprocessor, Terminal Adapter (TA) and Digital Signal Processor (DSP).
7.2. Requirements of the PC used for upgrading
The system requirements are determined by the Operative System in use: Windows 95
©
or
Windows NT
©
. These operative systems dictate the computer’s minimum processor and
available RAM memory specifications. With Windows 95
©
the minimum configuration is a
Pentium family processor with 16 MB RAM memory. The software installation requires 3 MB
hard disk space and up to 20 MB for user configurations. A mouse and a free serial port are
also required.
7.3. Connections for computer control
A female connector, labelled “CONTROL PORT”, is mounted on the rear of the Audiocodec
chassis for connection to an external computer communicating through RS-232 protocol. The
PC is connected through its serial port. The connections are as follows:
RX
2
TX
3
GND

The pins connecting the Audiocodec and PC are as follows:
TLE-02D : DB-9 MALE
PC : DB-9 FEMALE

7.4. Firmware upgrading
The operation to upgrade the firmware is very simple. A floppy is available for Firmware
upgrading.
Important: The equipment cannot be used for any other operation, such as making a call etc.,
during the process of upgrading the Firmware.
The upgrading procedure is as follows:
First of all, the “TLE-02D Firmware Upgrade” Program must be installed into your system like
any other Windows application. Just follow the instructions contained in the floppy.
Before commencing the upgrading process, the PC and
AEQ TLE-02D
must be interconnected
using the PC serial port and the TLE-02D Control port as previously described.
Once connected, run the application “TLE-02D Firmware Upgrade”, whereupon the following
screen will be seen:
