ISDN is a high-speed method of sending voice and data on a digital phone line to national and international destinations.

Its speed and clarity mean that customers can use it to send and receive text, voice, video and images in seconds. ISDN currently allows users to transmit data, high speed faxes, picture quality videotex, broadcast quality audio and slow scan TV.

ISDN is based on the conversion of information into a digital form. Digitisation involves sampling information and converting it into a number of zeros or ones. Digital information has many advantages over analogue information in that it can have higher quality, it can be transmitted much more quickly and, of course, it is compatible with computers.

Other advantages of Reach’s Telecom’s ISDN include the relatively rapid transmission rate which means it can handle several times the data rate the Public Switched Telephone Network (PSTN) can support.
