For a start, a single PC at an NMC can be connected to the Internet via an Internet Service Provider (ISP). Such connection can be established using a normal telephone line or it can be a wireless connection. It should be configured as a dial up connection and segregated from the WMO GTS.
The next step could be, to have a multi-user arrangement by setting up a LAN and to connect to it an e-mail installed PC. It should then be possible for a number of users connected to the internal LAN to access the Internet using a single modem out of the e-mail installed PC. (Ref.: Annex 4). This dial up arrangement could provide e-mail and web hosting at the ISP and FTP between the NMC, ISP and the Internet.
