Leveraging your existing copper voice lines for data connectivity lets you create a seamless, flexible, and highly cost-efficient communications system. Basic Rate Interface (BRI): Single Line Service uses an ISDN digital network architecture to enable reliable data communications without the expense of dedicated lines, modems and cabling—while accelerating both voice and data far beyond the speed of standard telephone lines. Multiple communications can share a single line simultaneously, including voice, video, and data, with digital clarity. Multiple B channels for high-speed circuit-switched data, complemented with a separate D channel for low-speed packet-switched data, let you support a broad range of applications with optimal efficiency.
