Catena Networks Expands CNX-5 Product Line to Support Cost-Effective, Large Scale Rollout of DSL Services; Four Carriers Now Evaluating New DS3 Configuration.Business Editors/High-Tech Writers SUPERCOMM 2002 Booth #23666 ATLANTA--(BUSINESS WIRE)--June 3, 2002 At SUPERCOMM 2002 today, 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 announced that it has expanded its CNX-5 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 System product line to include a DS3 configuration. With this option, carriers can optimize backhaul bandwidth by aggregating ATM traffic from multiple CNX-5s onto a single DS3 network interface. "By offering a variety of backhaul options, Catena enables service providers to deploy the simplest and most cost-effective system to suit their unique requirements," said Gary Bolton, vice president of product marketing for Catena. "In particular, the DS3 configuration gives carriers an economical way to provide DSL to a greater number of subscribers." The CNX-5 Broadband DSL System is a card-for-card upgrade solution for Lucent SLC (Subscriber Loop Carrier) Lucent's designation for its digital loop carrier (DLC) products. See digital loop carrier. See also 386SLC. (R) Series 5 (SLC-5) 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. systems. It enables service providers to deliver Plain Old Telephone Service (POTS) and DSL services on any copper pair, without reducing POTS density. Four service providers -- one incumbent local exchange carrier ILEC, short for incumbent local exchange carrier, is a local telephone company in the United States that was in existence at the time of the break up of AT&T into the Regional Bell Operating Companies (RBOCs) also known as the "Baby Bells". (ILEC (Incumbent Local Exchange Carrier) A traditional local telephone company such as one of the Regional Bell companies (RBOCs). Contrast with CLEC. See ELEC and TELRIC. ) and three independent operating companies (IOCs) -- are evaluating Catena's CNX-5 system with the DS3 backhaul option for use in their networks. With the DS3 backhaul capacity, the CNX-5 helps carriers such as CC Communications support high-bandwidth applications, including video, for their broadband subscribers. "Catena's CNX-5 system enables us to seamlessly upgrade our SLC-5 remote terminals to deliver broadband services," said Vic Slaughter, assistant general manager for CC Communications. "With the new DS3 configuration, we delivered high-speed Internet See broadband. access and more than 40 channels of digital video, via our 'OnNow!' program, to subscribers served from our SLC-5s." Catena's DS3 solution consists of a DS3 WAN card, a Fiber Enhanced Channel Test Unit (Fiber ECTU ECTU Extension Computing Technology Unit (Oregon State University) ECTU Enhanced Channel Test Unit ECTU European Credit Transfer Units ) and a two-port integrated POTS+DSL linecard. The DS3 configuration aggregates DSL traffic from as many as 15 SLC-5s, upgraded with the CNX-5. The DS3 WAN card and Fiber ECTU perform aggregation, ATM switching, traffic management and network interface functions for all Catena linecards installed in those SLC-5s. Additionally, the DS3 WAN card acts as a system manager, monitoring the integrity of the interconnections and managing the overall ATM traffic. It also monitors loss of AC power and can disable DSL service, as required, to preserve lifeline POTS service. The Fiber ECTU interfaces to Catena's linecards over the legacy SLC-5 backplane without new cabling or rewiring. One Fiber ECTU is inserted into each SLC-5 dual channel bank, while a single DS3 WAN card provides the DS3 network interface for all the DSL lines. The CNX-5 provides a cost-effective, scalable solution for deploying DSL service to the 20 million subscribers served by SLC-5 remote terminals. Service providers can add linecards as needed as needed prn. See prn order. to expand DSL availability in two-line increments. This simple card-for-card upgrade eliminates the need for overlay solutions such as network-side POTS splitters, mini-RAMs and remote DSLAMs. Once installed, carriers can provision DSL via the CatenaView Element Management System, without costly truck rolls. Catena will demonstrate the CNX-5 system and the SUPERQuest award-winning CN1000 Broadband Loop Carrier in booth #23666 in hall B4.
