Colt 03-October-2007 06:37:50 PMComments wiki.answers.com/.../What_is_the_meaning_of_Pstn_abbraviation Posted by crouse www.webopedia.com/TERM/P/PSTN.html Posted by crouse Public switched telephone network. The oldest and largest applications network in the world Posted by crouse The public switched telephone network (PSTN) is the network of the world's public circuit-switched telephone networks, in much the same way that the Internet is the network of the world's public IP-based packet-switched networks. Originally a network of fixed-line analog telephone systems, the PSTN is now almost entirely digital, and now includes mobile as well as fixed telephones. The PSTN is largely governed by technical standards created by the ITU-T, and uses E.163/E.164 addresses (more commonly known as telephone numbers) for addressing.
