We have a partial T1 at one of our branches that my boss would like to share. Our main internet connection is at our main branch. Our branches are connected with point-to-point T1 lines. Obviously there are routers at each branch that route the traffic. (Cisco 2600 Series). Even though we already have an internet connection, how can I use the one partial T1 line across the branches so when I plug in one laptop at each branch it uses that interent connection which is completely seperate from all the other once?

I don't think you can do what you're thinking. At least, I've never heard of anyone doing something like this.

Generally speaking, if you have a fractional T1, you're getting a piece of the full 1.54 Mbps...whatever amount you're paying for. Not a whole T1 (1.54 Mbps) and only using a portion of it with the rest sitting idle.

You can do it. I should know how to do it too. Just not sure at this moment. I was going to restudy on it too. Seems it was on a test somewhere. For the most part you can tunnel to a proxy. Depends on what you have at the other end too. Any 2000/2003/linux servers? Any enterprise level switches?

The T-1 with routers on each side can be used for Vlans depending on how you set it up. Might depend on if you have dedicated T-1 but that is only some settings. As above a T-1 is just a wire of sorts.

Lemme see what book it is in. I have it somewhere.
