After innumerable attempts carried out through ISDN nets etc… We realise that the only manner to receive and transmit data in the speediest way possible, was to install a HDSL system. To day, thanks to HDSL. We can transmit and receive data not only with a velocity of 2 MB per second, but we are able to supply our customer with a personal e-mail box, where they can store all their work as they prefer, with no limits of time and space. It will be sufficient to call us and agree upon the name of the user. Ten minutes later the customer will get his unlimited space to unload his own files.
