SDSL - The High-speed Solution for Business

Businesses have several choices for high-speed Internet access. The most talked about high-speed Internet services are ADSL and cable modems, both of which are designed for residential use. Local telephone companies and cable television providers are heavily advertising ADSL and cable modem services in an effort to generate mass-market appeal for their respective products. For business customers, SDSL service from New Edge Networks is superior to both ADSL and cable modems. SDSL is a true business-class high-speed Internet service.

Listed below are the key differentiators between SDSL and phone company ADSL - the only DSL service offered by most phone companies and an explanation of why cable modems are not suitable for business use.

Service Level Agreement
Network performance and reliability are extremely important to business customers. When access to the Internet and email fail, it means lost revenue. Service level agreements between New Edge and the Internet Service Provider (ISP) guarantee that SDSL connections will perform at optimal levels, or New Edge is subject to financial penalties. Because phone companies do not offer service level agreements on their ADSL service, they tend to overload their networks with too many subscribers, creating network congestion and slow speeds on their customers' lines.

Symmetrical Speeds
Symmetrical Digital Subscriber Line (SDSL) service from New Edge provides End Users with upstream and downstream speeds as fast as 1.1 Mbps, approximately 35 times faster than a 28.8 Kbps dial-up modem. Asymmetrical Digital Subscriber Line (ADSL) service from the phone companies provides slower speeds upstream than downstream. Typically, the upstream speeds on ADSL are not fast enough to perform business applications such as web hosting, video conferencing, and e-commerce. Even sending an email with a large attachment can be difficult and slow on ADSL. SDSL, on the other hand, provides plenty of upstream speed to meet the bandwidth needs of most common business applications.

Security
Network security is also a high priority for business customers, as proprietary systems and information are at stake. Because SDSL is an "always on" connection, it requires advanced security. To protect the intellectual property of business customers, New Edge offers a routing solution which comes with firewall software, so businesses can build a barrier between their networks and computer hackers. Alternatively, telephone companies generally include only a simple bridge with their ADSL service. Bridges do not address security needs because they generally do not include firewall capability.

Analyzing Cable Modems
Cable modems are not suitable for business use either, even though some customers might be tempted to use them. The cable network is shared, which means as the number of cable users increases, the speed on each individual's line decreases. At times of peak Internet usage, cable modem speeds decrease dramatically. Secondly, a shared network is inherently less secure than a dedicated service like DSL; neighboring cable customers can more easily intercept data or hack into another user's computer. Finally, the upstream speed on a cable modem generally is no higher than 128 Kbps. Therefore, cable modems are unable to provide acceptable speed or security for business purposes.
