Appendix F ISDN Module
An Integrated Services Digital Network (ISDN) is one of the most rapidly expanding technologies for transmitting data and voice over wide area networks (WANs). The popularity of ISDN is due to its high-speed WAN connections at low cost, enabling greater productivity not only for home office workers or internet users, but also for corporate branch offices and remote sites.
In comparison, ISDN can transfer data more than four times as fast as a cutting-edge 28.8 Kbps modem. In its simplest form, ISDN offers the Basic Rate Interface (BRI), which has two 64Kbps B channels and a single 16Kbps D channel. The B channels can be combined, making the maximum transmission rate of 128Kbps. Furthermore, data compression enables an ISDN link to achieve up to 512Kbps transmission speeds.
ISDN provides high-speed remote access that is ideal for applications where analog connections are too slow and T1 connections are too expensive.
The ISDN Router module for the TE100-S55 is an excellent solution for connecting individuals or offices to headquarters or to the internet/intranet. It offers the equivalent bandwidth and reliability of leased lines at a significantly lower cost.
The ISDN Router module uses a single ISDN BRI capable of sending data over one B channel for data rates of 64Kbps or use both B channels for data rates of up to 128Kbps. Optional data compression can boost throughput up to 4-to-1 (512Kbps), depending on the data being transferred.
