Integrated Services Digital Network (ISDN)

Paper Summary:

This paper explains that Integrated Services Digital Network (ISDN) differs from the traditional form of telecommunications, namely the phone line, in that it is the reverse of standard telephone service provisioning. The author stresses that the ISDN should not be viewed as a task of communications but rather as a business solution; having verified that the ISDN service provider supports the desired features, the network designer must select the ISDN equipment and services, which support the company's business requirements. The paper relates that ISDN faces competition with such services as DSL and cable modems, which have been able to provide 10 to 20 times the bandwidth for a cheaper price; however, the one area that other services cannot beat is the voice services.

From the Paper:

"ISDN brought the "third wave of internetworking to corporations and consumers." What the third wave meant is that ISDN was able to bring networks to small remote offices, individuals who telecommute and those who work from, and those who just want quicker Internets service for personal use. One downside to using ISDN is that it charges for time used. If it is used extensively, than it is more cost effective to lease a separated phone line. Also, network managers who may use ISDN need "to understand that ISDN is not always deployed to the letter of the standards set forth by the International Telecommunications Union (ITU)." "
