1. General description

This Download-box has two objectives compared to the previous download. Increased
download speed and eliminating the use of master phones. The speed is accomplished by
using a fast synchronous connection between the Dl -box and the target. The need for a
master-phone is eliminated, by using a FLASH Card to store the software packages for a
variety of phones one a single FLASH card.

2. Features

2.1 Download Box

• Single download

This feature lets the user select a software package in the flashcard to be downloaded
and a target port at which the target MS/UE is connected.

• Multi download

This feature lets the user select a software package in the flashcard to be
downloaded. The download will be conducted on all four ports progressively.

• Flashcard browse

This feature lets the user browse the content of the flashcard inserted in the DL -box.

• LED indicators

The four MS/UE ports each have a LED indicator to show when a connection to a
MS/UE is busy and thus should not be disconnected.

4. File handling

• Storing files on MMC card.

To store files on the MMC card, the user need a PC with a MMC card reader installed.
The MMC-card reader works like other drives on the PC and can be handled by any file
manager program. When storing a new software for the phone, the file must be saved
in the root of the MMC card, because the Dl-box dosn’t look for files in subdirectories
on the card.

• Deleting files

Software that isn’t used anymore can be deleted from the PC through the MMC card
reader. WARNING : there is a file Named Flash loader.fl stored on the MMC card. This
file must never be deleted because this file is necessary for the download procedure.
