Subject: Google Data Centers: Where the internet lives Message-ID: <508383EB.email@example.com> Take a look inside Google's high-tech data centers. When you're on a Google website, you're accessing one of the most powerful server networks in the known Universe. But what does that actually look like? Here's your chance to see inside what we're calling the physical Internet. http://www.google.com/about/datacenters/gallery/#/ Neal McLain

Well, since the surplus physical assets of that defunct CLEC ended up sitting in my office before being sold or otherwise disposed of, I can tell you that the Superline modem has no value except as part of a Superline system. But the modems were what ran out before the DSLAMs did. They are out of production, and a handful of rural telcos may still be using them. We sold a couple of the DSLAMs on eBay that way. For the sake of the audience, SuperLine was a proprietary DSL built by AG Communications Systems around the turn of the century. AG was by then a Lucent subsidiary. Paradyne built the CPE; AG/Lucent built the DSLAMs. The modulation technique was based on Paradyne's MVL, which was basically QAM in a ping-pong mode -- no echo cancellation, but each side got the full line for a period of time. The maximum speed of SuperLine was 704 kbps, but usually less; on the other hand it maintained connectivity at 200-300 kbps out over 20 kilofeet of wire, well past where ADSL crapped out. So it was a good rural system. SuperLine differed from MVL by adding two telephone lines. So your data speed went down when the phone was in use, but otherwise it gave good-quality phone service (prioritized Frame Relay, actually). It never really caught on, so a handful of carries had it, mostly because they served long loops (we had a lot of those here in Massachusetts and a lot of "donut" rings with no DSL around ADSL-served COs). Paradyne was bought by Zhone who probably has no knowledge of the product. -- Fred Goldstein k1io fgoldstein "at" ionary.com ionary Consulting http://www.ionary.com/ +1 617 795 2701

Message-ID: <20121021235120.GA22129@telecom.csail.mit.edu> Does Microsoft Oppose Verizon Spying? Verizon allegedly wants more control over WP8 A street test 'proved' that users are clueless about Windows 8, yet Microsoft Surface Tablet preorders sold out. Verizon Wireless was bragging about spying on its customers before rumors started flying that there is trouble between Verizon and Windows Phone 8. The wireless carrier allegedly wants more remote device management control than WP8 offers.
