What is ELECTRONIC SWITCHING SYSTEM? What does ELECTRONIC SWITCHING SYSTEM mean? ELECTRONIC SWITCHING SYSTEM meaning - ELECTRONIC SWITCHING SYSTEM definition - ELECTRONIC SWITCHING SYSTEM explanation. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. In telecommunications, an electronic switching system (ESS) is a telephone switch that uses digital electronics and computerized control to interconnect telephone circuits for the purpose of establishing telephone calls. The generations of telephone switches before the advent of electronic switching in the 1950s used purely electro-mechanical relay systems and analog voice paths. These early machines typically utilized the step-by-step technique. The first generation of electronic switching systems in the 1960s were not entirely digital in nature, but used reed relay-operated metallic paths or crossbar switches operated by stored program control (SPC) systems. First announced in 1955, the first customer trial installation of an all-electronic central office commenced in Morris, Illinois in November 1960 by Bell Laboratories. The first prominent large-scale electronic switching system was the Number One Electronic Switching System (1ESS) of the Bell System in the United States, introduced in Succasunna, New Jersey, in May 1965. Later electronic switching systems implemented the digital representation of the electrical audio signals on subscriber loops by digitizing the analog signals and processing the resulting data for transmission between central offices. Time-division multiplexing (TDM) technology permitted the simultaneous transmission of multiple telephone calls on a single wire connection between central offices or other electronic switches, resulting in dramatic capacity improvements of the telephone network. With the advances of digital electronics starting in the 1960s telephone switches employed semiconductor device components in increasing measure. In the late 20th century most telephone exchanges without TDM processing were eliminated and the term electronic switching system became largely a historical distinction for the older SPC systems.

Speedy Cutover Service, SXS switching cutover to ESS filmed live at Glendale CA central office, 1984
 
04:35
A brief but surprisingly exciting 1984 video showing the preparation and live, real-time cutover from Step By Step switching system (SXS) to a new electronic switching system (ESS) in Glendale, California. Western Electric offered the Speedy Cutover Service to switching offices throughout the Bell System. Western Electric installers would visit a facility and prepare it, installing the new equipment inside the facility. They would identify and mark the existing cables that would need to be cut, then prepare employees for the cutover to the new ESS system. Previously a cutover from step-by-step (or from crossbar service) to ESS would take many frantic minutes, upwards of an hour, during which time active telephone service would be lost mid-call. With the speedy cutover service – 51 installers simultaneously cutting 927 cables as fast as possible, all on cue – the interrupted service could be brought down to well under a single minute. The climax here is unquestionably the moment of truth, the cutting of the cables, which is shown in real time. After making sure no emergency calls are underway, and with a shout of "Let's cut it!" the race is on, with three camera set-ups and a disco score capturing and preserving the moment of truth.

The Traveling Telephone Switching Machine - AT&T Archives
 
07:50
See more from the AT&T Archives at http://techchannel.att.com/archives The #5A Crossbar switcher, built by Western Electric at the Columbus Works, was a telephone switching machine that could handle either around 1000 lines, or up to 2000 with an extension upgrade. This made it ideal for smaller towns and communities, new large subdivisions, and larger companies. The crossbar switch itself took up 10 by 42 feet, and weighed 25 tons. The machine was pre-assembled in Ohio, and then trucked to its final installation site. This film shows the assembly and transportation, and further details about the crossbar switch's "plug and play" type of capabilities. The Columbus Works were one of the Bell System's later plants, built specifically for switching equipment manufacture, and opened in the late 1950s. It eventually manufactured not just the crossbar switch but also the 4ESS digital switch. The last major manufacturing effort AT&T ran at the plant was its Airloop, which was a wireless system announced in 1995 that was a potential replacement for crossbar-type switching systems in hard-to-reach areas. It could bring quantities of new lines to the network wirelessly, without having to build in new trunk lines to a site. At its peak, the Columbus Works employed around 12,000 workers, including 1,000 Bell Labs employees alone. In 1996 it became part of Lucent Technologies, which sold the plant in 2003. Today, the office building on the site is still occupied, but much of the manufacturing plant is empty.

03:54
The ESS, or electronic switching system, developed by the Bell System over a period of about 20 years, revolutionized communications in this country. This film footage (there is no sound), found in the AT&T archives, shows the grand opening on May 30, 1965, of the first implementation of an ESS switching office in the United States. These were the obvious benefits to the customer that the ESS made possible: three-way calling, call waiting, and speed dial. But the ESS streamlined internal functions as well-it paved the way for remote electronic monitoring and maintenance, providing modern diagnostic tools and requiring far fewer technicians to maintain the system. The implementation of ESS was tied to the development of the transistor. Though the transistor was first invented in the 1940s, a first test ESS office was online by 1958 in Morris, Illinois still retained some vacuum tube technology. Before the 1965 ESS installation, a private business, the Brown Engineering Company, in Cocoa Beach, Florida, tested an intermediate system in 1963. The commercial installation in Succasunna, New Jersey, was the very first of the No. 1 ESS. It initially served only 200 customers (of the town's 4,300) immediately after opening, but was designed to serve 65,000 phone lines, and switch 100,000 calls per hour. The second No. 1 ESS office was installed in Maryland in 1966. By 1974, there were 475 No. 1 ESS offices around the country, serving 5.6 million phone lines. The No. 1 ESS also became the basis for an iteration of AUTOVON, the military's own communications network. (AUTOVON was eventually replaced in the early '90s by DSN, the defense switched network.) The No. 1 ESS was superseded in 1976 by the invention of the #1AESS. The Succasunna central office's original No. 1 ESS depicted in this 1965 footage was finally taken out of service in 1992.

See more from the AT&T Archives at http://techchannel.att.com/archives The purpose of this film was to show employees, back in 1951, how calls were automatically switched through an SxS office. This film gives a general appreciation of the importance, complexity, and cost of switching equipment in an average 1950s telephone office. The path of a call is illustrated as it runs through a demonstration unit. "Careful adherance to Bell System maintenance practices" is stressed. While this is only part I, Part II eventually showed the equipment in various types of use, and Part II showed the internal circuit operations. Switchers today are digital and look drastically different. These systems at this time were still not even transistorized, so this film shows a system that's not only years back in time, but many generations back in terms of technology.

Digital Switching System Basic introduciton
 
02:08
Digital switching It’s like a switch but a bit different switch. It is a element required for the communication. So in order to communicate we need one source and a destination and they should be connected by a line. Its simple for communication between two point. But as the number of points increases there will be large number of communication lines between them. For example communication between 4 points would require 6 lines of connection. This can be calculated as follows: Formulae: So as the number of communicating points increases there is the massive increase in the number of communicating lines. And if we add distance between them as a factor then cost price of the network system would increase a lot. So in order solve this problem we can make a switching system. In which all the communicating points are connected to the switching system only. This system also known as telephone exchange and provides the communication lines as per needed. The switching is done by the embedded software.
