Public domain film from the Library of Congress Prelinger Archive, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and equalization. en.wikipedia.org In 1892, AT&T built an interconnected long-distance telephone network, which reached from New York to Chicago, the technological limit for non-amplified wiring. Users often did not use their own phone for such connections, but made an appointment to use a special long-distance telephone booth or "silence cabinet" equipped with 4-wire telephones and other advanced technology. The invention of loading coils extended the range to Denver in 1911, again reaching a technological limit. A major research venture and contest led to the development of the audion—originally invented by Lee De Forest and greatly improved by others in the years between 1907 and 1914—which provided the means for telephone signals to reach from coast to coast. Such transcontinental calling was made possible in 1914 but was not showcased until early 1915, as a promotion for the upcoming Panama-Pacific Exposition in San Francisco in the spring of the same year.

IP Telephony TCP and UDP Transport Layers Overview

www.xorcom.com - Technical discussion of IP telephony transport layers UDP and TCP (Transmission Control Protocol). The transport layer encapsulates application data into datagrams to be transferred to the lower layers and across the network, and is responsible for virtual host-to-host communication. It adds options such as connection-based transfer, data ordering, flow control, reliability, and congestion avoidance. The following two protocols are covered in detail: TCP - Transmission Control Protocol - is reliable, ordered, connection-based (heavyweight), streaming UDP - User Datagram Protocol - is unreliable, not ordered, lightweight (small, nimble), datagrams (fire and forget) The video also details the common ports used for IP telephony and their associated protocols.
