What Is ISDN
ISDN stands for Integrated Services Digital Network and provides end-to-end digital connectivity over the telephone network. ISDN is a phone line - with one big difference: it's digital. If you think of a line as a pipe that that carries information from one point to another, the difference with ISDN is that the 'pipe' is a lot bigger, and a lot cleaner. Replacing traditional phone lines with ISDN is like replacing old one-inch lead water pipes - which carry water slowly, and pollute it with impurities - with brand new three-inch stainless steel pipes - which carry a lot more water, much faster, with no impurities. Analogue modems must dedicate some capacity to error correction and retransmission. This overhead reduces the actual throughput, while an ISDN line can dedicate all its capacity to data transmission.
ISDN is based on the fact that, in the modern telephone network, analogue speech is broken down (digitised) into a series of binary digits (bits) and transmitted at a rate of 64,000 bits per second (64 kbps) on channels set up through the network. It is then converted at the remote exchange back to an analogue signal, which arrives at your phone. ISDN simply replaces the analogue path between you and the exchange with a fully digital service. As such, ISDN can provide an end to end (i.e. all the way from one user in their premises, to another user in their premises) digital transmission path.
There are two different types of ISDN access; Basic Rate access (supplied as ISDN 2e by BT) and Primary Rate access (supplied as ISDN 30 by BT). ISDN 2e This service provides two 64 kbit/s channels (Known as the B-channels) that can be used for communication and one 16 kbit/s channel (known as the D-channel) that is used for call set up and signalling thus leaving the full bandwidth of the B-channels available for use.
This service requires the existing wiring to be reconfigured and a different box to be fitted on the wall inside your office which is known generically as an NT1 (Network Terminating equipment) and also a different box in the serving telephone exchange.
