unfortunately, there appears to be no standard line encoding for E3 lines, so if you want to have E3-Ethernet converters, you must use them in pairs, on both ends of the line. This rules out having eg your E3 terminating somewhere inside an STM1/4/... trunk on the other side, but many carriers only offer this kind of setup. So you're almost guaranteed to have a non-working line if they have, say, a Cisco 12000 on their end where your line terminates inside a trunk, and you have the simple fiber with only that one E3 incorporated. I've been told that the situation improves quite a bit when you have STM1 instead: There, a standard exists, but it doesn't appear to be widely tested if it actually works. Best, --Toni++
