QKSAND, This gets back to the distinction between the inexpensive residential (consumer) grade DSLs we discussed yesterday employing pooled line approaches, and the more robust commercial grade offerings with dedicated 'net access. "What makes mPhase's DSL unique is its simultaneous delivery of high speed Internet access, digital video, and telephone service over an existing telephone line on an unshared platform." I am not familiar with this company's products other than in name only. Perhaps someone else would like to comment. Regards, Frank Coluccio

Re: mPHASE (sym:XDSL) and RADSL Technology qksand, Just doing some more DD on my DSL companies to watch. While browsing the mPHASE website, I came across some interesting claims. Sounds very much like a GTE test going on in my area. But GTE is experimenting with VDSL. I was told it was 1meg data service, lots of TV channels and phone service too(I posted upstream somewhere). I thought VDSL was the only DSL flavor capable of delivering what mPHASE claims to do with RADSL. But I notice that mPHASE avoids the distance from the CO issue in it's claims. My feeling is the mPHASE product(s) is just one small part of being able to deliver what they claim they can. I can't seem to find anything more than a single product, the "Traverser Intelligent Network Interface." It appears you drop this in the CO and bingo, an ILEC can compete with a MSO <G>. Below are some claims. IMHO, it's time to get the salt shaker out, but their comments are worth noting for the record. Maybe I'll be eating my post a few years from now. Wouldn't be the first time. MikeM(From Florida) ************************** The mPhase TRAVERSER allows telephone companies to simultaneously deliver 1Mbps of high speed Internet access, up to 400 channels of digital television programming, and traditional voice service over existing loop infrastructure.... Digital Subscriber Line (DSL) technology allows telephone companies to provide high speed Internet access and maximize the potential of installed telephone lines. mPhase offers a specific type of DSL called Rate Adaptive Digital Subscriber Line (RADSL), allowing high speed data transmission at speeds of 6 Mbps downstream and up to 1 Mbps upstream, increasing throughput more than 200 times faster than 28.8 K Internet connections. ___________________ While it is true that ISDN provides faster access than analog modems, it is expensive, difficult to install, impacts existing telephone traffic, and is not fast enough to satisfy consumer demand. mPhase XDSL, on the other hand, is fast, affordable, and works with Plain Old Telephone Service (POTS)....Our newest mPhase TRAVERSER enables data speeds up to 6.2 Mbps downstream, and up to 1.0 Mbps upstream - increasing throughput up to 50 times faster than an ISDN connection. And, because transmission speed is rate adaptive, mPhase XDSL adjusts to length and signal quality of telephone line, automatically selecting the highest practical operating speed. When comparing the mPhase TRAVERSER with cable modem, the TRAVERSER advantages are clear: coaxial cable is relatively expensive - and does not provide efficient down/upstream data delivery. _________________ Hart Telephone Company Provides mPhase Technology with a "Real World" Test...Goal is set to sign up 1,000 new customers for simultaneous TV, data, and telephone service using in-place, copper infrastructure. The Hart Telephone Company in Hartwell, Georgia, is preparing to give local CATV operators a run for their money by offering customers Internet access and digital TV in addition to telephone voice service...all simultaneously, and all over existing copper wires. The key is mPhase RADSL (Rate Adaptive Digital Subscriber Line) coupled with the mPhase TRAVERSER Digital Video and Data Delivery System. The mPhase RADSL technology in Hart's central office will save the millions of dollars needed to install cable to provide TV service to residential customers**. And the excellent phone service Hart customers already enjoy will travel unimpeded over the same already installed, twisted pair copper lines as their digital TV signal and Internet connection. TVs, computers and telephones will each be plugged into the mPhase TRAVERSER Intelligent Network Interface, installed at the end-users premises. Progress reports from Hartwell, Georgia, indicate that Beta tests are going well and that the system is delivering all that was promised. The mPhase XDSL transceiver is providing data throughput 50 times faster than ISDN, and more than 200 times faster than 28.8K Internet connections. Recently, the Hart Telephone/mPhase project announced 99 channels of MPEG2 digital video was being transmitted through use of the TRAVERSER system. __________________ Central Office Equipment --- Now, ILECs, CLECs and RBOCs can have the equipment they need to offer broadcast quality MPEG-2 digital video and high-speed data to their residential and business markets. All using the existing copper infrastructure. Developed in alliance with Georgia Tech Research Institute and Microphase Corporation of Norwalk, Connecticut, the mPhase Traverser Digital Video and Data Delivery System works in conjunction with mPhase's Traverser Intelligent Network Interface (INI) to provide simultaneous digital video, Internet access and telephone to the home or business. _____________________ Here's a link to their products and it appears the devil are in the details. Looks like video, voice, data is good out to 15,000 feet. Beyond that I guess it's data only. Funny but the links to get full details of their equipment in the diagrams is dead. Plus the site, is painfully slow to access with my cable modem (I know it has nothing to do with RADSL, but just ironic how slow their site is). mphasetv.net
