- A subject dear to my heart at present! You have entered a new realm of
- expense and heartbreak, I'm afraid... Most 56K leased lines use an NTU
- (Network Terminal Unit) which can only produce a Synchronous serial
- output; your PC, however, cannot cope with a synchronous signal, so you
- need to find hardware that will do so. While there are relatively
- inexpensive Synchronous cards for PCs, you have a real problem with
- driver software for them. I have been unable to find a synch-asynch
- converter which can work reliably much above 19K2, so that avenue
- doesn't seem promising.
-
- In the end, you'll probably find that you only have a few options:
-
- 1: Get a pair of Ciscos or Proteon routers, one for each end of the
- wire. Both brands have X.21/V35 ports which will handle speeds up to
- and beyond 64K.
-
- 2: Buy two copies of the Novell MPR (multi-protocol router) with a new
- Novell product called WAN Links, and a pair of Novell Synch+ cards. You
- can eliminate one of the MPRs if you are prepared to use your NetWare
- 3.11 server as a router.
-
- Option 1 is more expensive than option 2, but provides more management
- facilities, and routing support for a wider range of protocols. Option
- 2 is cheaper, and if you only want light-to-medium load IP routing, is
- a perfectly adequate approach.
-
- Hope this helps a little,
-
- Cheers!
