[comp.dcom.lans] T1 and distant IP networks

kurt@hi.UUCP (Kurt Zeilenga) (09/13/87)

We have:

	1) two IP ethernets separated by 120 miles
	2) a T1 line between the two.

I would like an IP (or ethernet if IP wasn't readly available)
repeater or bridge or gateway so the two networks can talk.  Anybody
have any information about off the shelf products that could be used.
Cost estimates would be greatly appreciated.

cisco Systems makes a router (gateway) that can do what you want.
The AGS-1E1T @ $11,698 includes a box, one ethernet card, and one T1
rate serial card (two T1 interfaces/card). I have been using a similar
setup for almost a year. It works well. The box is noisy (large fan).
You need a server that has TFTP to download files and BOOTP (it may
also be able to use something else), or you can buy a non-volatile
memory board @ $1350.

  You would need two routers for your application. If you have a
large number of workstations on each end, you would do better with
a router than with a bridge. Bridges have to transmit broadcast
packets. Routers don't. Routers allow you (actually force :-) to
secure access to subnets. Bridges can't. If you have a small
number of workstations than a bridge may be what you need. Bridge
makes them. I don't know anything more about them, firsthand.

hope this helps

PS. I have no connection to cisco other than as a user, but you can
