We've used them extensively in our network for years (we have about 2,600 of them in the network). They actually used to be Ceterus devices (it's possible that Hatteras merged with Ceterus or something, but I'm not up on my vendor acquisition current events). We mostly use the UTS 810 and UTS-900 models. To be honest with you they work fine, but once something goes wrong, it's pretty bad because they are kind of flaky. We've had to simply reboot a lot of them to get the problem fixed, rather than actually figuring out what is really wrong with them and fixing that so it doesn't happen again. We get lots of trouble tickets for speed issues from customers who have them on their circuits, that's for sure. If I were you I'd probably go with Aktino products. We have a ton of those too, and I've never really had a problem with them.

Maybe I'm just not in the know on this but if these prefixes/ASes shouldn't be seen on the internet, shouldn't there be more of a public flogging to remove them? ------------------------------ Message: 2 Date: Fri, 14 Oct 2011 16:45:45 -0400 From: "Scott Berkman" <scott@sberkman.net> To: "'Graham Wooden'" <graham@g-rock.net>, <nanog@nanog.org> Subject: RE: [OT] Overture's Ethernet over bonded Copper products Message-ID: <00fc01cc8ab2$3fdcd2b0$bf967810$@sberkman.net> Content-Type: text/plain; charset="windows-1256" I've been working with them (it's really the Hatteras Networks products) since before the acquisition. I don't have much to compare to in terms of experience with the competing products, but I can tell you we've been very happy with the equipment, and I've heard lots of horror stories from Zhone customers. Hatteras' support was also phenomenal. I haven't seen any change yet since the acquisition except we have a different sales guy. The biggest challenge is that when dealing with 3rd party (iLEC) copper pairs, you really don't know what you are going to get until you turn up the circuit. There can also be a lot of fingerpointing when things break because the circuits you buy from the iLEC are generally cheap and don't have very high requirements for when the techs test and accept the circuit. Hope that helps, -Scott -----Original Message----- From: Graham Wooden [mailto:graham@g-rock.net] Sent: Thursday, October 13, 2011 6:40 PM To: nanog@nanog.org Subject: [OT] Overture's Ethernet over bonded Copper products HI operators, Been looking at Overture?s ?Ethernet over Copper? product line; any you folks have any real world experience with them?
