Catena CN1000 Broadband Loop Carrier Achieves NEBS 3 Certification; Company Announces General Availability of CN1000 & Associated Management Systems.Business Editors/High-Tech WritersREDWOOD SHORES, Calif.--(BUSINESS WIRE)--Sept. 30, 2002 Catena ca·te·na n. pl. ca·te·nae or ca·te·nas A closely linked series, especially of excerpted writings or commentaries. [Latin cat Networks today announced that its CN1000 Broadband Loop Carrier (BLC BLC Boston Library Consortium BLC Bethany Lutheran College (Minnesota) BLC Back Light Compensation (video cameras) BLC Belo Corporation (stock symbol) BLC Broadband Loop Carrier ) has achieved NEBS Level 3 certification. The company also announced General Availability of the CN1000 and its associated management systems. "By aggressively working to achieve these milestones, Catena is enabling carriers to rapidly and seamlessly deploy new Broadband Loop Carriers systems in their access networks," said Mark Feeley, vice president of systems development at Catena Networks. "These BLC systems provide a competitive advantage by helping carriers reduce their capital and operational expenses, deploy new broadband services and sustain revenue growth." Incumbent Local Exchange Carriers (ILECs) and many other North American and global service providers require that vendors' products meet Telcordia's stringent Network Equipment-Building System (NEBS) requirements for safety and reliability, before deploying those products in their networks. Telcordia has grouped its NEBS criteria into three functional levels, which cover both physical and electrical requirements. The Level 3 criteria provide the highest assurance of product operability Operability is the ability to keep a system in a functioning and operating condition. In a computing systems environment with multiple systems this includes the ability of products, systems and business processes to work together to accomplish a common task such as finding and and are suited for equipment applications, which demand minimal service interruptions over the equipment's lifecycle. Level 3 includes criteria of Level 1 and Level 2, plus criteria for effective operation in outside plant environments (resistance to high and low temperatures; airborne contaminants; electrostatic discharge at installation and repair points; and power inductions from the loop and trunk plant, etc.). Catena's CN1000 Broadband Loop Carrier is a packet-based broadband access system designed for the cost-effective delivery of voice, data and video services. It is a high-density platform for both environmentally hardened outside-plant and central-office applications. Unlike Digital Loop Carrier In telephone communications, a technology that increases the number of channels in the local loop by converting analog signals to digital and multiplexing them back to the end office. (DLC (1) (Data Link Control) See data link and OSI. (2) (Data Link Control) The data link layer protocol (layer 2) that is used in IBM's SNA networking. See SNA, data link protocol and Microsoft DLC. ) and Next Generation Digital Loop Carrier (NGDLC NGDLC Next Generation Digital Loop Carrier ) solutions, Catena's CN1000 Broadband Loop Carrier provides POTS+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 on every line. Carriers can offer POTS and broadband on every line at a price competitive with narrowband NGDLC systems. Further, the CN1000 enables carriers to remotely provision and manage POTS and broadband services, without the operational costs (truck rolls) typically associated with ADSL See DSL. ADSL - Asymmetric Digital Subscriber Line turn-up and churn. The CN1000 also supports a full suite of special services -- such as Coin, DID and ISDN BRI, etc. -- without reducing the number of available POTS lines. In addition, the CN1000 simplifies the access network by integrating the functions of 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. , Digital Loop Carrier and Media Gateway.
