Primary Rate ISDN Service offers you the power to create a seamless
communications system that speeds and smoothes the flow of information
without the expense of dedicated lines, modems, and special cabling.
Rate ISDN Service links your PBX to our advanced central office
system to provide you with global, digital connectivity and the
full functionality of Centrex service. Primary Rate ISDN Service
is the digital network architecture that allows you to transmit
voice, data, video, and image, separately or simultaneously -
either over standard telephone lines or fiber optic circuits via
a standard interface. A single ISDN channel is a fast and flexible
information management tool, but Primary Rate ISDN Service is
24 times more powerful - bundling 24 ISDN channels for delivery
to your premises.
Primary Rate ISDN Service configuration is known as 23B + D: 23B
channels for transport of voice, data, video, and image at 64
Kbps plus a single D channel for call setup and control. The 23B
channels may be rearranged in a wide variety of ways to accommodate
your highly specific needs.
