OVERVIEW
The SG-1 is a service creation platform optimized for delivering differentiated services to residential, mobile, and
private subscribers. The SG-1 enables service providers to offer attractive new services that can be selected
dynamically and automatically by their wireless, dial-up and broadband users.
The SG-1 can provide services over existing infrastructure, integrating smoothly with leading network access
servers, RADIUS servers, databases, and billing systems.
The SG-1 can be deployed to meet the requirements of Internet Service Providers (ISPs), Digital Subscriber Loop
(DSL) providers, cable providers, or "hot spot" (802.11) wireless Local Area Network (LAN) providers.
FEATURES
Designed to easily integrate into operations of existing and emerging service providers, the SG-1 has the following
features:
•Network Centric and Scalable Architecture: is designed for a service provider network, scales to carrier class
requirements, and allows for a more easily maintained solution because it is deployed in a centralized location.
This minimizes the number of systems and makes service changes faster and more economical. As part of this
network centric architecture, Customer Premises Equipment (CPE) software, "cookies", and local service points
can be eliminated.
•Dynamic Provisioning: allows users to change a service package or user profile "on the fly" without forcing the
user to disconnect and then reconnect. This vital feature enables streamlined service provisioning without
involvement of a service provider's personnel and immediate service creation following the user's service-selec-
tion decision.
•Flexible Network Integration: can be easily operated with existing access infrastructure, requiring minor
changes in network and billing servers.
•Universal Platform: the processing engines support different access types: xDSL, cable, wireless, and dial-up.
The SG-1 also handles ATM and Gigabit Ethernet.
•Flexible Scalability: is available in a range of capacities, with varying configurations up to 64,000 virtual ports
per chassis. As a result, service providers can easily scale SG-1's capacity to meet their changing needs.
•Hot Swappable Cards: has redundancies built in including the ability of cards to be mixed and matched.
•Subscriber Redirection: subscribers can be redirected to selected web sites or portals, regardless of their indi-
vidual Uniform Resource Locator (URL) selection. This feature enables increased traffic to specific sites and
personalized communications with individual users. It also enables a service provider to control and authorize
access to incidental users that are not regular subscribers to the network. Subscriber redirection is a key build-
ing block for customized services that can be easily created using SG-1 including walled gardens, selective and
targeted promotional activities, anti-virus protection, and other services and applications.
•Anti-Spoofing Mechanism: supplies an anti-spoofing prevention mechanism, which blocks an unauthorized
user's computer from pretending to have a different IP address than it really has.
•Billing and Accounting: provides accounting information for each selected service using the standard RADIUS
protocol. This enables network providers to bill their users based on the actual services used. Unique account-
ing capabilities are provided to simplify billing including those required for Session accounting and Service
accounting using simple RADIUS commands.
•Carrier Class: supports telecom standards including Point-to-Point Protocol (PPP), Layer 2 Tunneling protocol
(L2TP), SNMP, and others.
Note: Not all can be eliminated. For example, CPE equipment (such as, DSL modem, etc.) will still be
needed. Cookies may still be needed depending on the application.
