Since 1 September 1994, it is possible to obtain full access to the nine CORDIS databases via the online ECHO host. Use of the ECHO public password will provide access to an online registration form which, when completed, provides the user with a personal password. User documentation and a CORDIS Reference Manual will then be sent by mail. In order to access ECHO, the following options are available: - Direct dialling using a normal telephone line: Tel. +352-420347; - PSDN/PSS/PAD (packet switching data network connecting e.g. X.25 or X.28): NUA (Network User Address): 270448112; Usually the prefix for the NUA is 0 (zero): 0270448112. In the UK use the NUA prefix A9: A9270448112; - Academic research networks of RARE/COSINE: Select the EuropaNET (formerly IXI) or the PSS option and dial following NUA (for EuropaNET): 204370310099; - Internet: Users should "telnet" to actual command is telnet.echo.lu Once connected to ECHO the user types the public access code "ECHO" which will then display an opening menu inviting the user to choose a language option. The user then selects option 9 for online registration.
