Alexander Graham Bell was a Scottish-born inventor, scientist and engineer who is credited with patenting the first practical telephone. He also co-founded the American Telephone and Telegraph Company (AT&T) in 1885.
Electrical telegraphs were point-to-point text messaging systems, primarily used from the 1840s until the late 20th century. It was the first electrical telecommunications system and the most widely used of a number of early messaging systems called telegraphs, that were devised to communicate text messages quicker than physical transportation. Electrical telegraphy can be considered to be the first example of electrical engineering.
A telephone is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be easily heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via cables and other communication channels to another telephone which reproduces the sound to the receiving user. The term is derived from Greek: τῆλε and φωνή, together meaning distant voice. A common short form of the term is phone, which came into use early in the telephone's history.

The Communications Workers of America (CWA) is the largest communications and media labor union in the United States, representing about 700,000 members in both the private and public sectors. The union has 27 locals in Canada via CWA-SCA Canada representing about 8,000 members. CWA has several affiliated subsidiary labor unions bringing total membership to over 700,000.

The International Brotherhood of Electrical Workers (IBEW) is a labor union that represents approximately 775,000 workers and retirees in the electrical industry in the United States, Canada, Guam, Panama, Puerto Rico, and the US Virgin Islands; in particular electricians, or inside wiremen, in the construction industry and lineworkers and other employees of public utilities. The union also represents some workers in the computer, telecommunications, and broadcasting industries, and other fields related to electrical work.
Communications, Energy and Paperworkers Union of Canada, abbreviated CEP in English and SCEP in French, was a largely private-sector labour union with 150,000 members, active from 1992 to 2013. It was created in 1992 through the merger of three unions: the Canadian Paperworkers Union, the Communications and Electrical Workers of Canada, and the Energy and Chemical Workers Union. See below for some other unions that were merged into the CEP. CEP/SCEP was affiliated to the Canadian Labour Congress.
The Canadian Union of Postal Workers is a public-sector trade union representing postal workers including letter carriers, rural and suburban mail carriers, postal clerks, mail handlers and dispatchers, technicians, mechanics and electricians employed at Canada Post as well as private sector workers outside Canada Post. Currently comprising upwards of 50,000 members, the Canadian Union of Postal Workers has historically been labeled as militant because of some of the actions undertaken since its inception in 1965 to help guarantee rights to all postal workers. According to former president Jean-Claude Parrot, "We succeeded to get the support of the membership because we earned our credibility with them...we got that reputation [of militancy] because we earned it."
The invention of the telephone was the culmination of work done by more than one individual, and led to an array of lawsuits relating to the patent claims of several individuals and numerous companies.
Signalling System R2 is a signalling protocol for telecommunications that was in use from the 1960s mostly in Europe, and later also in Latin America, Asia, and Australia, to convey exchange information between two telephone switching systems for establishing a telephone call via a telephone trunk. It is suitable for signaling on analog as well as digital circuits.
The Bell Telephone Company was the initial corporate entity from which the Bell System originated to build a continental conglomerate and monopoly in telecommunication services in the United States and Canada.
The history of telecommunication began with the use of smoke signals and drums in Africa, Asia, and the Americas. In the 1790s, the first fixed semaphore systems emerged in Europe. However, it was not until the 1830s that electrical telecommunication systems started to appear. This article details the history of telecommunication and the individuals who helped make telecommunication systems what they are today. The history of telecommunication is an important part of the larger history of communication.

This history of the telephone chronicles the development of the electrical telephone, and includes a brief overview of its predecessors. The first telephone patent was granted to Alexander Graham Bell in 1876.
Alexander Graham Bell honors and tributes include honors bestowed upon him and awards named for him.
The rotary machine switching system, or most commonly known as the rotary system, was a type of automatic telephone exchange manufactured and used primarily in Europe from the 1910s. The system was developed and tested by AT&T's American engineering division, Western Electric, in the United States, at the same time when Western Electric was also developing the Panel switch. When AT&T selected the Panel System for large American exchanges, development and sales of the No. 7-A Machine Switching System, its formal commercial name, were transferred to Western Electric's international division in Belgium. In Europe and other continents the system was met with considerable commercial success.
Telecommunication, often used in its plural form, is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems are excluded from the field.
The Australian Telecommunications Employees' Association (ATEA) was an Australian trade union representing technical and trades employees in the telecommunications industry from 1912 to 1992.
