I'm very interested in strong ADSL2 performers. The grief and worry about getting one "tamed" though is prohibitive. I would have to get a generous soul to config, tame and test these devices times three, no small amount of nuisance, which I wouldn't expec to be done for nothing. But I would need to test one on a 65dB d/s attn line or worse before committing to it. I'm out for the bleeding edge ADSL2 performer, AS YOU KNOW.
The fact I have three could mean I can exploit the redundancy to work against the risks of disruption due to resyncs, perhaps a situation that wouldn't work for a single unit. But multiple devices may just give me an opportunity to push things too hard and get away with it, providing I don't undo the gains by upsetting DLM.
Note to self - don't know anything about DLM in ADSL2.
Andrews and Arnold's shop has a VDSL2 / xDSL modem router by Zyxel, don't know if this is exceptional in ADSL2.
Am a bit worried about whether designers will start to prioritise VDSL2 and higher in their designs in terms of how much they care about ugly sister that is old-fashioned ADSLx.
