Dave, I've not explored this beyond the recent press release stage. The Multiple Virtual Line, or MVL, approach effectively yields similar results, when deployed in multi-tennant/shared-tennant dwellings, as some other network designs which use T1s to deliver dynamic bandwidth assignment at the CPE router level to the subscriber, using switched (sometimes shared, ouch) Ethernet to cover up to the last ~300 feet. The latter configuration also makes use of policy based network elements (usually incorporated in the router) to allow for flexible amounts of customization and billing arrangements based on the sub's preferences and affordability. Maybe someone else can shed more light on this one. Incidentally, I cheated and went to the web site for more insights and noticed that Paradyne is preparing for an IPO. Just FYI. Regards, Frank Coluccio

Apparently, in difficult cases on longer loops (20-30k feet) where other implementations didn't work well (or at all), MVL performed well (albeit at reduced rates). Dave: While this aspect of MVL is good news, I question how valuable such attribute is in today's rapidly advancing marketplace. DMT-DSL from PacBell is tariffed in California out to 17,500 ft at a minimum bps rate of 384K. Along heavier gauge wire, its being deployed at this minimum throughput as far out as 22,000 ft. So how "reduced" are the rates over MVL DSL? If we're talking less than 300Kbps, I don't see the lure of this type of DSL that significant to warrant deployment in competitive markets -- the larger urban areas. I say all this with the knowledge that the ability to deliver ubiquitous ADSL deployment via the deployment of DSL plant equipment is not very far off.
