ISDN for Private Branch Exchange

ISDN is a high-speed, fully digital telephone service. ISDN upgrades current analog telephone network to a digital system. ISDN lets you talk, or transmit data and high-resolution images all at the same time on a single line. It can operate up to 128 kbit/s, which is more times faster than current analog modems. ISDN can efficiently speed up transfer of information over the Internet or over a remote LAN connection, especially rich media such as graphics, audio or video or applications that normally run at LAN speeds.
