We currently use a permanent telephone link at 9600 Baud between IRAM Granada and the University of Granada for our Internet link. In the past we have suffered from several problems (configuration errors, hardware problems, telephone line cuts, ...). The velocity of the current link limits its usage (in particular for file transfer and WWW), and we are testing an ISDN link (64 kBaud) as a replacement of the analog line. However, for the installation we depend on the telephone company TELEFONICA and the support of the organization that runs the andalusian research network.
