Hi. Just my 2p on this.
We used to use the Zyxels (both models) in NI a few years ago and spent a lot of time in Bracknell with Zyxel in the test labs - they are (maybe were) more than happy to welcome you on site there. However we had random hardware and lock up problems along with high port failure counts on them and eventually removed them in favour of Alcatel at considerable expense. Perhaps they've improved but given they are the same models numbers I would presume firmware only if any. Personally I wouldn't look at them again. Aside from that RAD (TTB) tackle is awful. Had good experience of Actellis but it's far from a respectable price point.

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 -- [email protected] | http://www.crouchingbadger.com -------------- next part -------------- An HTML attachment was scrubbed...

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!!

Interesting timing, because I'm going through exactly the same investigation at the moment, althrough more on the ADSL than the EFM side. > We have a number of Zhone MXK319s already deployed.

I had a long discussion with Zhone's recommended reseller in the UK (The Kenton Group) this morning. They have pointed me at both the MXK-319, and also their 1U 48 port boxes (DSL/Voice only) - MX-150 and MXP-150. On the EFM side, they also recommended the Actelis Networks products. http://www.microtel.co.uk/products/?cat=69 One thing which did surprise me is that the MXK-319 (even when fully populated with 72 port ADSL2+ cards) works out more expensive per port than the MX-150. Okay, you have a slightly lower support overhead with having thing in one chassis with one management interface, but I can work around that when we do the integration into our OSS/BSS backend systems. I was also looking at the Zyxel products (as mentioned by Neil) - they have comparable products to the Zhone ones - IES-1248 for a 1U 48 port DSLAM/MSAN, and the IES-5000 for a chassis based solution, which has a similar range of linecard option to the Zhone (including ADSL2+ and SHDSL/EFM). I've not yet managed to speak to Zyxel or a reseller about these yet (any recommended sales contacts?). Based on pricing found via google, the Zhone and Zyxel are a similar price point. The bloke from Kenton Group that I spoke to wasn't particularly complimentary about the Zyxel products (but then, he was trying to sell me the Zhone stuff).
