(CTDI CTDI Computed Tomography Dose Index CTDI Common Rail Turbo Diesel Injection ), a global leader in the engineering, manufacturing and maintenance of telecommunications networks, announced today the release of the XCel-4e, its latest broadband DSL DSL in full Digital Subscriber Line Broadband digital communications connection that operates over standard copper telephone wires. It requires a DSL modem, which splits transmissions into two frequency bands: the lower frequencies for voice (ordinary extension product. With the growing demand for broadband internet access Broadband Internet access, often shortened to just "broadband", is high speed Internet access—typically contrasted with dial-up access over modem. Dial-up modems are generally only capable of a maximum bitrate of 56 kbit/s (kilobits per second) and require the full use of a , many remote users have limited options for broadband DSL. CTDI's new XCel-4e optimally addresses this demand by delivering 8 Mbps DSL service to remote users, including subscribers located more than 100 kft from a DSLAM (DSL Access Multiplexor) A central office (CO) device for ADSL service that intermixes voice traffic and DSL traffic onto a customer's DSL line. It also separates incoming phone and data signals and directs them onto the appropriate carrier's network. See DSL. . CTDI is committed to bringing broadband access See broadband and wireless broadband. to rural users by enabling carriers to deliver high-speed service See broadband. to any subscriber, anywhere in the network. The XCel-4e system transparently extends existing central office or remote DSLAM-based ADSL See DSL. ADSL - Asymmetric Digital Subscriber Line 2+. Each XCel-4e system accepts four ADSL2+ subscriber lines from the DSLAM. These four lines are then carried on a single copper pair at a rate of 8 Mbps. Using line-powered repeaters, providers can reach four customers per system at a distance of 40 kft from the DSLAM*. For longer loops, CTDI will be introducing a locally powered repeater to deliver ubiquitous broadband access of up to 8 Mbps per user for all subscribers, regardless of location. As opposed to passive repeaters which simply amplify the signal, the XCel-4e fully terminates and regenerates the signal, allowing it to be repeated multiple times. "The XCel-4e presents an enticing business case for carriers since it enables 8 Meg DSL service at any distance using existing copper plant. The release of the XCel-4e also shows CTDI's commitment to our customers through innovation and our investment in R&D," stated Brian Parsons, director of CTDI's Products Division. Over the past months, CTDI has successfully deployed the XCel-4e with three customers. These beta trials have included varying cable characteristics and physical geographies. In each case, the end-user achieved more than 8 Mbps service, thus providing incremental sales for the carrier through this new high-speed DSL product offering. The XCel-4e is now available from CTDI. For more information, or for additional CTDI products, visit www.ctdi.com. *Rates and distance depend on the wire gauge.
