Ben, We're not doing ADSL, but we are in the process of rolling out (proper) EFM services. We're using the very excellent Hatteras (now Overture Networks) HN4000 units. They individual units have 40 pairs each, however they stack together; up to 5 units per stack (200 pairs).
They do some really nice stuff like E-LAN and E-TREE across different pair bonding groups as well as the usual E-LINE type setup. This allows you to do localised L2VPNs from a single exchange without using resources on a VPLS or similar type aggregation device. The kit is really solid - I'd recommend it. Way better than the RAD boxes you get given with TTB circuits, and even better than the Actellis EFM equipment, which was our second choice. Overture have a really decent presales team too. They loaned us kit for ages to play with, as well as sending their UK technical guys up to see us for a full day of demos. Let me know if you need a contact at Overture. If anyone else has experience with ADSL/VDSL DSLAMs - I'd be interested to hear your thoughts on what's available. We're looking at doing a sub-loop unbundling project - so it needs to be hardened; living in a street-side cabinet in the cold Scottish weather!!

Since the baby arrived life has become more small smells than small cells. Anyway, after such a great response to my LNS/L2TP questions last time, I thought I'd ask people's opinions on DSLAMs. I'm looking for low-cost, fairly dumb ADSL/EFM DSLAMs, data only, capable of user-side VLANs. Some of the 24-port 1u devices look suitable, but I'd be interested in chassis too. We have a number of Zhone MXK319s already deployed. The early days of deploying them were rage-filled with an inconsistent cli, off-by-one bugs and their occasionally forgetting how to do switching, but as long as you don't touch them them they just sit there. Any suggestions appreciated. Thanks Ben -- b...@crouchingbadger.com<mailto:b...@crouchingbadger.com> | http://www.crouchingbadger.com<http://www.crouchingbadger.com/>
