Uptime guarantees and same day service are standard in the business telecommunications world, which recognizes that they deliver a mission critical function. Cable companies, in contrast, operate in a monopoly environment which prevents competition driven service levels. DSLnetworks maintains a nationwide private network which allow us to offer the scalability, flexibility and cost savings of a Virtual Private Network for employees and remote offices throughout major metropolitan areas across the United States, regardless of who their local phone companies are. We can connect operations and employees over our ATM network without ever using the public internet. DSLnetworks lets you maintain the security and reliability of a private network without the administration and high cost of private lease lines.
Cable modems can only connect telecommuters to networks within the same cable system.
While there are generally only a couple of big cable systems, each municipality still has a unique network with it's own loop. There are currently no provisions for cable systems to connect companies in one region with its offices or employees in another. By contrast, the cable monopolies have just won a Supreme Court victory which allows them to maintain exclusive arrangements for data access on their network. Unlike a DSL connections, which use a dedicated circuit for each user, accessing the internet with a cable modem does not provide the secure connection required for virtual private networks or ecommerce. Anyone who is on that network can intercept all of the packets which come across it, regardless of the requesting IP address.
