[Latin cat Networks introduced the first in a series of solutions that will enable the mass-market deployment of residential 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 and provide carriers with a seamless migration path to the converged, packet-based public network.

See SNA, data link protocol and Microsoft DLC. ) Systems enables service providers to deliver Plain Old Telephone Service (POTS) and Asymmetric Digital Subscriber Line (communications, protocol) Asymmetric Digital Subscriber Line - (ADSL, or Asymmetric Digital Subscriber Loop) A form of Digital Subscriber Line in which the bandwidth available for downstream connection is significantly larger then for upstream. (ADSL) services on any copper pair, without reducing the number of available POTS lines. The CNX-5 gives carriers a fast, cost-effective and scalable way to provide revenue-generating DSL services to the more than 20 million residential subscribers served by SLC-5 remote terminals. Three of the 10 largest carriers in the U.S. have agreed to begin lab and field evaluations of the CNX-5 system in the first quarter of 2001. The exploding demand for residential broadband services has created an urgent need for service providers to deliver DSL to customers served by these remote terminals. According to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. the research firm Telechoice, DSL deployments in the U.S. alone are expected to grow to nearly 10 million by 2002. A recent study by the Cahners In-Stat Group found that ADSL will capture more than 70 percent of the total DSL market by 2004. Further, RHK RHK Ratahallintokeskus (Finnish: Finnish Rail Administration) RHK Ryan Hankin Kent (RHK, Inc. marketing consulting firm) RHK Rigshospitalets Kollegium (Copenhagen, Denmark dorm) forecasts that by 2003, more than 50 percent of target ADSL residential subscribers will be served from remote terminals. However, current solutions for delivering DSL from remote terminals -- ranging from bolt-on mini Remote Access Multiplexer (mini-RAM) systems to remote Digital Subscriber Line Access Multiplexers (DSLAMs) and adjunct cabinets -- are expensive, inefficient and don't scale to support large volumes of users. These solutions require additional space in a remote terminal cabinet, or worse, an incremental investment in additional concrete pads and cabinets. "To establish DSL as a mass-market service for consumers, carriers need a low-cost, scalable solution that addresses last-mile bottlenecks related to remote terminals," said Patrick Hurley, DSL analyst for Telechoice. "Solutions that allow service providers to inexpensively and easily upgrade their existing DLC infrastructure, like Catena's CNX-5 system, will help facilitate large-scale deployments of DSL service."

Typically the president of the company, the CEO reports to the Chairman of the Board. of Catena Networks, said, "Catena's linecard integration of POTS and DSL enables broadband deployments today and facilitates a seamless, line-by-line transition to the new converged, packet-based public network of tomorrow." The Catena CNX-5 system consists of an integrated 2 POTS and 2 DSL port channel unit, an ATM multiplexer card, and the CatenaView Element Management System (EMS), which are the only elements required to upgrade the SLC-5 to support DSL. This simple, card-for-card upgrade eliminates the need for POTS splitters, cross-connects, external cabling, mini-RAMs, and additional pads and cabinets. In addition, service providers can expand DSL availability in two-line increments as residential demand for DSL increases. By allowing service providers to handle all DSL service requests through remote provisioning from their network operations center See NOC. Network Operations Center - (NOC) A location from which the operation of a network or internet is monitored. Additionally, this center usually serves as a clearinghouse for connectivity problems and efforts to resolve those problems. via the CatenaView EMS, the CNX-5 dramatically reduces operational costs. Catena's programmable silicon technology also allows carriers to manage evolving ADSL standards by delivering new features via software downloads - not costly hardware upgrades. The CNX-5 effectively leverages carriers' investments in installed SLC-5 equipment and provides the industry's lowest capital, service activation and lifecycle cost solution. The Elements of the CNX-5 ADSL Upgrade The Catena Enhanced Channel Unit (ECU) is the linecard replacement that integrates POTS and ADSL interface technology within the existing SLC-5 chassis. For the technician, the installation of the ECU is the same as a standard SLC-5 POTS channel unit. The Catena ECU sports a red lever on the front of the unit for quickly and easily determining which lines are DSL-enabled. To support DSL services on the SLC-5, the Catena Enhanced Channel Test Unit (ECTU ECTU Extension Computing Technology Unit (Oregon State University) ECTU Enhanced Channel Test Unit ECTU European Credit Transfer Units ) replaces the existing Channel Test Unit. By employing existing system resources to facilitate communications between the ECU cards and the ECTU, there is no need for external cabling, either between cards or to an external POTS splitter, thus simplifying installation. Once installed and connected to backhaul facilities, the ECTU is ready to be provisioned for DSL services from the network operations center. The CNX-5 upgrade offers three backhaul options -- T1, 4xT1 IMA (Interactive Multimedia Association, Annapolis, MD) An earlier trade association founded in 1988 originally as the Interactive Video Industry Association. It provided an open process for adopting existing technologies and was involved in subjects such as networked services, scripting , and DS-3 -- that allow the carrier to start inexpensively and increase backhaul bandwidth as needed as needed prn. See prn order. . To provision and manage mass-market DSL services, the CNX-5 uses the CatenaView EMS and a complete Application Programming Interface (API) suite. Expandable to hundreds of thousands of lines, CatenaView can be distributed across client/server platforms. The API provides the interfaces necessary to electronically link the CNX-5 to upstream operation support systems and, by utilizing a TCP/IP-based protocol, enables interoperability regardless of platform, operating system, programming language, network hardware or software. Pricing and Availability Catena's CNX-5 is currently shipping to service providers. Pricing for the complete CNX-5 ADSL system starts at less than $3,000.
