+1 for Hatteras (now Overture) from me.
We conducted pretty extensive lab and real-world deployment trials of
Hatteras, Actelis Zhone EFM kit and Hatteras came out on top in most
areas (disclaimer, this was a couple of years ago and I've not
re-trailed since). Nice stacking features - copper pairs can load
balance across different stack members for redundancy.
Auto-provisioning is nice and easy. CLI is fairly Cisco-esqe and easy
to merge into a rancid style backup situation, and there is also a
decent web-frontend when it's needed. Actelis, at least when we
trialled it, relied on a piece of Windows software primarily which could
be frustrating but the kit itself was solid (has this changed?)
Similar to Ben we also found that the Zhone CLI could be frustrating,
but worth noting that the right Zhone chassis can be deployed as more of
an MSAN with EFM/ADSL cards in the same chassis so depends on your
requirements.
Cheers,

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!!
Thanks,
Charlie

Hi again all,
Apologies for those who I missed by not going to UKNOF last week.
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
