MINNEAPOLIS--(BUSINESS WIRE)--Nov. 20, 2000

ADC (Nasdaq: ADCT; www.adc.com), a leading global supplier of fiber optics, network equipment, software and integration services for broadband, multiservice networks, today announced significant enhancements to its award-winning next-generation CMTS (cable modem termination system) products that allow cable operators to support open access for subscriber flexibility and to provide next-generation data and voice services for increased revenue and profits.

These enhancements to ADC's Cuda 12000 IP Access Switch and Cuda Provisioning Manager are designed to allow cable operators to give subscribers; choice of their content provider and to provision different classes of data services to residential and corporate customers based on the DOCSIS (Data Over Cable Service Interface Specifications) 1.1 specifications.

"Open Access, DOCSIS 1.1 and end-to-end QoS are hot topics in today's expanding broadband market," said Mark Komanecky, vice president of marketing and business development for ADC's Cable Systems Division. "We, again, will be providing the market with innovative solutions that provide cable operators with the ability to tackle these issues with the highest level of service, flexibility, and scalability - all within their existing infrastructures."

The Cuda 12000 IP Access Switch supports open access through its policy-based routing capabilities. In contrast to virtual router solutions that offer support for only a limited number of ISP's limited scalability and more complex to manage, the Cuda 12000 will help enable cable operators to build upon their existing network infrastructures without placing a limit on the number of ISPs they support.

Working in conjunction with the Cuda 12000, the Cuda Provisioning Manager subscriber management solution allows the operator to configure a selected ISP when provisioning subscribers and cable modems. The ISP selection can be configured at three levels (cable modem, PC, and subscriber) to provide the operator with the greatest amount of flexibility within the network. With the Cuda Provisioning Manager, no tunnelling or Network Address Translation is required. It also supports on-line self-provisioning which allows subscribers to change ISPs and service levels on-demand.

"Native IP solutions such as policy-based routing are emerging as the preferred architecture for implementing multi-ISP access over shared DOCSIS access networks," said Michael Harris, president of Kinetic Strategies Inc., a leading broadband research firm. "The approach taken by ADC helps MSOs maximize their multi-service IP network infrastructure and deliver the value-added services that benefit consumers and independent ISPs alike."

To address the market demand for DOCSIS 1.1 support and end-to-end Quality of Service (QoS), the Cuda 12000 platform now enables cable operators to provision multiple service classes and support profit-generating tiered data services as well as lifeline IP-based telephony services.

In addition to providing best-in-class support of the DOCSIS 1.1 specifications, the ADC Cuda 12000 platform provides significant value-added capability above and beyond the basic DOCSIS 1.1 specifications to enable very efficient bandwidth management that will help allow cable operators to realize an increase in revenues and profitability. Leveraging the industry's highest packet processing performance and 200+ Gb/s switching capacity of the Cuda 12000 platform and its MeshFlow(TM) architecture, the Cuda 12000 DOCSIS 1.1 implementation provides unsurpassed performance and flexibility. The distributed packet processing of the Cuda 12000 enables cable operators to add both port capacity and packet processing capability on an as-needed basis, as well as enabling tight quality of service control interfacing to backbone IP networks.

This value-added capability includes flexibly supporting the assignment of services classes across multiple ISPs, providing cable operators with the industry's most comprehensive support of multiple service classes within single or multi-ISP environments. Overall network performance and customer satisfaction should also be increased due to the cable operators' ability to appropriately queue and schedule traffic for optimum levels of bandwidth.

Availability

The Cuda 12000 IP Access Switch supports open access functionality today. General availability of Open Access features for the Cuda Provisioning Manager is scheduled for first quarter of 2001. DOCSIS 1.1 and QoS features are currently under test at CableLabs(R) in their first DOCSIS 1.1 certification wave and are planned for general availability in the same time frame.
