In this article we will discuss ISDN, will make brief discussion on ISDN, last article we discuss about STP.
Integrated Services Digital Network (ISDN) is a set of communication standards for simultaneous digital transmission of voice, video, data, and other network services over the traditional circuits of the public switched telephone network. It was first defined in 1988 in the CCITT red book.
An ISDN line is a digital line – your computer connects to the ISDN line (via a terminal adaptor) without having to convert the data into sound first. A basic rate ISDN line provides two ‘channels’, each of which can be used for separate calls, thus equivalent to having two regular lines.
The basic advantage of ISDN is to facilitate the user with multiple digital channels. These channels can operate concurrently through the same one copper wire pair. The digital signals broadcasting transversely the telephone lines. ISDN provides high data rate because of digital scheme which is 56kbps.
Simply put, ISDN is defined as an a set of communication standards for the transmission of data, voice, and signaling. It is a circuit-switched telephone network system that transmits packets of data across copper lines.
