A Shiva NetModem and a regular Hayes  compatible 2400 modem and Shiva's
software and TOPS software.  ALternatively I think you can use a 
Shiva NetSerial and a regular modem. Then presumably you could use the
Hayes 9600 modems.  Shiva recommends 2400 minimum, but we've tried
1200. Its rather slow but we did copy a 700k file with TOPS across
phone lines, it was an image and it took 2.25 hours to transmit!
A 20K application also was transferred and it ran no problem.
You can tell we are still testing it.  It doesnt like PBX lines to
much, dialing out of one lab line into another is impossible for us.
We are getting a data line installed.  Since I'm here at U of M you
can guess I am merely a customer of Shiva and TOPS.  TOPS is
definitely the way to go for small clusters of Macs.

Hope this is useful,
Cheers.
