 Ladies & Gentlemen,


    I have a customer with PA-POS-OC3 cards installed in a pair of
Cisco 7507s. Right now they can physically remove the line from the
first machine, plug it into the second, and things neatly switch over.


    They've asked me to come up with a remote control method of
switching the fiber optic line. The incoming circuit and two routers
are the only things we're ever going to switch at this location. This
solution does not need to be carrier grade, it just needs to be
remotely controllable.


    I suspect the answer is that anything that switches STM1 sonet
links is going to be large, heavy, expensive, and -48v - all things
that do not fit with what these guys are trying to do. if anyone has
any inspiration on how to accomplish this I'd be glad to hear it ...




                                                                       Neal
