Business data services have become the platform for all business services – voice, data, and video. In a US Business Services market that has been flat over the past few years, data services are rising. Over the next five years CMR projects that business data services revenues will increase to 82 percent of the total business services market, leaving voice and video in a distant second and third place. Business Data services include broadband (DSL, cable), TDM (PL, FRS, ATM), IP (Dedicated Access, VPNs), Ethernet, and Network Cloud services (Hosting, IP Applications). This report examines both the mature (PL, Broadband) and growing (IP, Cloud, Ethernet) data services. The report provides five-year revenue projections by each service, by business size (Small, Medium, Enterprise), and by channel (wholesale, retail). In addition to revenues forecasts the report includes projections on data services pricing and detailed demand forecasts, including subscribers, circuits, and port counts.
