Well, except that it actually does nothing of the sort. This is just another ethernet over sonet box, it takes the whole ethernet frame and slaps it inside a sonet frame for transport over a sonet network. If you want to transport ethernet services over sonet, for example to bridge two network networks via a traditional telco circuit, this is a reasonable way to do it. However, this is in no way a "converter", since it requires a matching box (or something with similar functionality) on the other end to pop off the sonet frame and hand off the original ethernet frame to the client side interface. -- Richard A Steenbergen <[email protected]> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)
