Using the Shasta 5000 BSN, wholesalers can offer ISPs a consolidated pipe for both DSL and dial, enabling ISPs to reduce their operational cost by managing a single circuit from a wholesaler. ISPs can also offer a global telecommuting service to their corporate customers by consolidating DSL and dial from multiple POPs to a single tunnel. The corporate customer reduces costs by dealing with a single ISP for its global telecommuting requirements without having to increasingly purchase larger and more powerful L2TP Network Servers (LNS) to terminate thousands of tunnels from many POPs. Dial subscribers will now be able to experience some of the same broadband services offered to DSL customers.

Increasing Wholesaler Revenue Streams
The wholesaler can increase their revenue stream by offering both access technologies. Using this unique platform, the wholesaler can easily offer a new access technology such as DSL while benefiting from existing operations infrastructure built on dial experience. By using the same aggregation platform, new value-added customized services can be applied to both narrowband and broadband subscribers.

" The need for a common platform to aggregate DSL and Dial customers is becoming more important as common services are applied to multiple access technologies. A universal solution that enables the various access technologies to converge allows service providers to apply their subscriber service policies regardless of whether the customer has arrived over a DSL or a dial circuit," said Anthony Alles, president and general manager of Nortel Networks Shasta IP Services business unit. "The Shasta 5000 Broadband Service Node is the unique platform that enables that convergence and yet is capable of providing customized services that are applied seamlessly to both dial and DSL customers."

New Business Opportunities for ISPs
ISPs gain by deploying the Shasta 5000 to provide a consolidated global telecommuting service for their corporate customers. The ISP can consolidate DSL and dial from multiple global POPs and perform tunnel switching to corporations. The Shasta 5000 will terminate the L2TP tunnels from multiple POPs, aggregate them and provide the corporation with a consolidated tunnel. Now, corporations are no longer required to purchase large LNSs to keep up with the demand for telecommuting by their employees.

The Shasta 5000 will also perform the LNS role at the ISP. Upon terminating the tunnels, the Shasta 5000 can provide a multitude of value added services such as firewalls, traffic shaping, local cache and content filter interaction, and content insertion, enabling the ISP or corporate customer to provide differentiated and customized services based on the customers' changing needs.

Optimized Nortel Networks Dial Wholesaling Solution
While the Nortel Networks Shasta 5000 BSN can work with any RAS, it provides an optimized dial access wholesaling solution when used with the carrier-class CVX 1800 access switch. With L2TP Tunnel Navigation, a capability unique to the Nortel Networks' CVX 1800 modem wholesaling solution, tunnels are selectively assigned between a network of CVX 1800 shelves to specific Shasta 5000 BSNs based on each Shasta 5000's subscriber capacity. If a LNS reaches capacity or there is a failure in the network, Tunnel Navigation routes calls to other units reachable and capable of terminating tunnels. This provides a robust tunneling solution.

About the Shasta 5000 BSN
The Shasta 5000 Broadband Service Node (BSN) is an integral part of the Shasta Subscriber Service System (SSS*) and includes the IP Service Operating System (iSOS*) and Service Creation System (SCS). The Shasta 5000 Broadband Service Node is designed to power the subscriber edge of the network, where last mile technologies like DSL, dial and other broadband technologies, meet the Internet backbone and where broadband subscribers will meet broadband services. The Shasta 5000 enables carriers, competitive local exchange carriers (CLECs) and ISPs to increase their competitive advantage by transitioning from the simple connectivity model enabled by first generation subscriber management systems, to a profitable, network-based, value-added services model. Enabling the aggregation of tens of thousands of subscribers in a single chassis, and with its unique multi-processor architecture with more than 100 CPUs, the Shasta 5000 also has the unparalleled processing power to apply sophisticated, stateful firewalls to each individual subscriber.
