JW@ << Installing POTS splitters is not an issue and worth the effort for Quality of Service(QOS). >> Forgive my ignorance, but physicaly what is a POTS. And is it something that can be easily installed by the customer?? ratan

<Installing POTS splitters is not an issue and worth the effort for Quality of Service(QOS)....Pay no attention to my humble opinions, I'm from a different school of thought, QOS, do it right the first time, and you'll find yourself way ahead in the game...> From the context of your post, it is apparent that your use of the term "Quality of Service" and especially your refernce of the specific acronym - "QoS", that you aren't quite clear on the specific technical use of this term. This term does NOT refer to some arbitrarily defined scale which ranges from "high" quality to "low" quality. Quality in the telco industry with this usage is more akin to "type". The following may be helpful in understanding these telco terms: "...Internet-based VPNs and tiered services require tight performance controls, achieved through traffic management and quality of service (QoS) or class of service (CoS) mechanisms. CoS mechanisms typically provide a coarse level of control, allowing net managers to classify certain types of users, applications, or servers as belonging to a certain class. For example, a service provider may establish a high-priority and low-priority class. Classes support different levels of service attributes but generally do not tightly define performance characteristics. QoS-based mechanisms, on the other hand, define performance attributes precisely. For example, ATM QoS enables tight control over bandwidth, cell loss, delay, and delay variation. By varying these parameters, service providers can craft many different types of tiered services...." <"How slow & cheap and lacking quality can they make it and still shove it down the consumers throat."> In addition, even with YOUR use of "quality", I would argue that there is clearly a market for a RANGE of access speeds (especially as a function of customer cost as we are seeing), especially until TRUE QoS service (years away) is available to those wishing to travel (and PAY for) first class throughput. <..Again IMHO, Splitter-less cannot work in higher speed ADSL modems, as the higher the speed the more bandwidth is needed, this leaves you have less margin for error tolerance between services (POTS, Upstream, Downstream...> This is inaccurate according to Globespan's recent offering: "..Using the patented Micro Data Filter, Globespan's newly introduced product line can achieve both symmetrical and asymmetrical speeds from 90,000 bits per second (90 Kbps) to 7 million bits per second (7 Mbps) and can reach distances up to 22,000 feet depending on product configuration. ''Today, our CiDSL is the only deliverable product offering that makes mass deployment of DSL service a reality,'' said Armando Geday, CEO of Globespan. ''It's a win-win solution for service providers and equipment manufacturers that can satisfy the pent-up demand for high speed Internet access.'' Globespan has developed special algorithms that can be software downloaded into the modem to automatically compensate for the specific home wiring/phone configurations where a Micro Data Filter is not easily installable..." from Message 2850755 <..Even for G.lite it will be hard to design a modem without having some type of splitter somewhere, either outside the dwelling, or just prior to the NIC/modem...> Well, Rockwell, Nortel, Aware and now Globespan all seem to offer true "splitterless" ADSL. Where do you get your information that they in fact still need a splitter somewhere? Just curious about your representations here. Steve
