We've used a few Zhone ETHX-344x4 (http://www.zhone.com/products/ETHX-3400/) and been happy with the reliability. Configuration was a bugger, but if you get one of those I can share my template.

The devices themselves are reliable and secure it would seem, but the speeds were are able to get are not. ie. we have deployed 'vdsl' and needed 3 lines to get up to 10x10 speeds. We are using an Adtran TA5000 on the other end to terminate our connections. The distance between the site and CO is not great (under 6k feet). What gives? Are we provisioning wrong, using the wrong equipment, or a combination of both? If we were able to get the speeds others have been reporting from VDSL, life would be great. Anyone feel free to contact me off-list or on, this has had me scratching my head for a while now.
