intelligent Access Network (iAN) Platform Creates Service Options for

Consumers, Carriers and Content Providers

ADC (Nasdaq: ADCT; www.adc.com) today announced the launch of the intelligent Access Network (iAN) platform. Historically, customers seeking access to broadband services have had to make a one-time trade-off between price and performance when ordering service. ADC's iAN is designed to deliver more options to the consumer, carrier and content provider for a more cost-effective service mix. The iAN platform will be showcased at Supercomm 2000 in Atlanta, June 6-8 (Booth No. 7439).

Unlike current DSL network provisioning, iAN provides customers with the industry's first real-time programmable DSL-based multi-service gateway, allowing them to set and change their own specific bandwidth and Quality of Service (QoS) levels with the click of a mouse on a personalized, home-page interface. Customers served by an iAN-equipped network can dynamically alternate between low cost, modest bandwidth capabilities and high-performance connectivity for use with the most demanding applications, such as full-motion DVD-quality video streaming. The iAN replaces today's end-to-end flat rate ADSL permanent virtual circuit (PVC) service with an enhanced user controllable alternative.

"Moving control of individualized user performance selections out to the edge of the network may well be one of the most significant changes to-date in the history of residential and small office/home office (SOHO) information technology," said Arun Sobti, senior vice president of ADC and president of ADC's Broadband Access and Transport Group (BATG).

"iAN redefines the model for true broadband service delivery, by enabling content, destination and quality of service (QoS) selection for broadband calls to be made by the consumer on demand."

iAN Expands Service Options for Consumers, Carriers and Content

Providers

Beyond these advantages to the consumer, iAN benefits incumbent and competitive local exchange carriers by enabling them to offer differentiated broadband services to their customers when bandwidth can be viewed as a commodity. Local carriers also benefit from being able to more efficiently satisfy a greater number of residential and small office/home office (SOHO) users per service node by allocating bandwidth on an as-needed basis. Content providers gain a higher quality, more efficient and satisfying means of delivering the robust content of premium ISP and complex interactive content to end users.

At the heart of the iAN platform is the patent pending Client Server Access(TM) architecture, from which subscriber requests for services are tunneled to a centralized server through a multimedia gateway (MG-1) located near the edge of the network. The MG-1 mirrors a high-speed, stackable next generation digital loop carrier and digital subscriber line access multiplexer (NGDLC/DSLAM) shelf. This environmentally hardened multimedia gateway supports any mix of user interfaces, including POTS, ADSL, HDSL2 and SDSL, for up to 2016 subscribers. Traffic streams are consolidated into uplinks of up to OC-12c, employing various signaling protocols such as GR-303, SVC and, in an upcoming release, IP/MPLS.

The most unique component of the iAN is the centralized service brokering server (SBS-1000), a general purpose UNIX or NT machine. The SBS-1000 receives all requests for services, and makes real-time changes in the MG-1 broadband flows and content streaming according to consumer demands. Additionally, the SBS-1000 manages the resulting billing requirements for the subscriber services provided, based upon a predetermined cost per unit of bandwidth selected by the customer.

"This separation of switching and control is a critical feature of the iAN architecture", said Michael Zimmerman, director of product management for ADC's Broadband Access and Transport Group. "The control layer in the server becomes an environment for creating new service models to be executed by the MG-1, enabling rapid development of powerful new capabilities and deployment virtually overnight. Simultaneously, this separation also simplifies installation, maintenance and upgrade, and facilitates centralized management and billing."
