Our company has 5 buildings, one is our corporate hq, and the other 4 are satellite offices. We are all located within the same city. Right now, our corporate office has a Full T-1 going to Building 1, while Buildings 2, 3 and 4 are all connected via a Frame Relay Cloud. The Frame Relay also goes to Building 1 for backup purposes in case the T-1 goes down.
I want to redo this configuration, because it seems like we're spending a lot of money on it. I was looking for some suggestions or opinions on how to redo this. Maybe have separate fractional T1's going to each building? Or can we somehow use the Full T1 going to Building #1 and continue it (or daisy chain, if you will) to Buildings 2, 3 and 4.
Any opinions and suggestions are most welcome. Thanks
