 ISDN Definition
We define ISDN |
ISDN - Integrated Services Digital Network. A technology that carries data over phone lines at up to 128Kbps for dialup users, but extends to fast broadband communications, too. It applies to the first three layers of the OSI and TCP/IP models. Slow to get started in the US, it is likely to be overtaken by the much faster DSL models over the next few years. |
