ISDN offers a big improvement in communications when compared to using a modem over an analog telephone lines. An ISDN can be used in either a switched or nonswitched mode. ISDN also has a very low error rate in comparison to analog technology.

Integrated Services Digital Network ISDN is a network technology that supports the digital transfer of simultaneous voice and data traffic along with support for video and fax over the public switched telephone network. ISDN gained popularity around the world during the s but has largely been supplanted by modern long-distance networking technologies. As telecommunications companies gradually converted their phone infrastructures from analog to digital, the connections to individual residences and businesses— referred to as the "last mile" network — remained on old signaling standards and copper wire.

ISDN was designed as a way to migrate the transition to digital signals. Businesses especially found value in ISDN due to the larger number of desk phones and fax machines their networks needed to support. Many people first came to know of ISDN as an alternative to traditional dial-up internet access.

Although the cost of residential ISDN internet service was relatively high, some consumers were willing to pay more for a service that advertised up to Kbps connection speeds versus the 56 Kbps or slower speed of dial-up connections. Eventually, the much higher network speeds supported by newer broadband internet technologies like DSL attracted most customers away from ISDN. Although a few people continue to use it in lesser populated areas where better options aren't available, most internet providers have phased out their support for ISDN.

ISDN runs over ordinary telephone lines or T1 lines E1 lines in some countries , and it does not support wireless connections. The standard signaling methods used on ISDN networks come from the field of telecommunications, including Q. The two main variations of ISDN are:.
