Leased Line Modems

Hello!

I have an existing installation using leased line modems, topography prevents any other option. We have had the modems fail twice now. I do not recall the first model, the current model is a MuLogic model. Do any of you have suggestions on a replacement ROBUST leased line modem?

ps. very cool water park at the W.E.M. you have there

I haven't used any lately, but we had good results using Control Microsystems 5902 modems: http://resourcecenter.controlmicrosystems.com/pages/releaseview.action?pageId=2491227.
