Given that "ftp works locally using tcp-ip" (thus probably telnet/rlogin),
your site is quite ready for Internet connectivity.  However, before you
can ftp/telnet/rlogin to a remote site, you'll need to find a site which
is already connected to the Internet, and is willing to forward packets 
for you. (By Internet, here I mean some network that is connected, 
directly or indirectly, to the Nsfnet or Arpanet backbone, and by 
packet switching --- which would exclude the present Bitnet and UUCP, 
and to a certain extent, CSnet.)

Note that connecting your site to the Internet is more of an administrational 
than a technical matter...

Technically, connection to your peer (the host which is already on
the Internet) are usually by means of a leased phone line, though in essence
any suitable transmission media of "any" data rate should work. (well,
actually, 9600bps is merely acceptable as far as performance is concerned.)
Since tcp/ip is just a software subsystem, surely it can be implemented
over switched (dial-up) lines --- you just need a driver to get the packets
off the line. (There is a package called "slip", implementing the serial line 
internet protocol. I haven't had experience with it, so I don't know 
whether it would work over dialups... I'd like to know though, so could
someone please enlighten?!)

Advantage over tip/cu?  well, too many, too many!! With tip/cu, you only
connect to one machine; with telnet/rlogin, you can possibly connect to 
hundreds of thousands, when given the right permissions and right routes...
And more importantly, file transfers work a lot better!

Have Fun! ;-)
