  • Inform your network administrator technical characteristics of the selected solution. It will verify that the configuration of proxies and other facilities will not be a problem. Companies that have a service Quality of Service (QoS) can even define a level of bandwidth reserved for your use.

  • Advise your customers to install an ADSL line dedicated to your connections. It may therefore be necessary to identify the premises of customers, a dedicated office in your trading. While this may, at first glance, seem contradictory with the idea of remote service , the fact of dedicating a room allows users to do not mix their different activities and to concenter easier. So you can install a remote training room at your customer, recommending the provision of a dedicated internet connection. The trainer will lead these courses from home, but learners should always move in a room dedicated to training.
