T200 Telex And Data Switching System
The T200 telex switching system produced by Hasler Ltd of Berne broke new ground in the modernization and spread of Telex. During the 1970s and 1980s it pioneered the introduction of digital equipment and the deployment of Stored Program Controlled (SPC) Exchanges, gradually replacing the former electromechanical telex networks. The first T200 telex exchange went into service in February 1972 in Hong Kong on the telex network of the telecommunications company Cable & Wireless. It was the world's first stored-program-controlled telex switch in public service with call switching over a digital data bus. A special feature of the T200 was a computer architecture designed to ensure uninterrupted operation based on three synchronously running processors with majority monitoring. (The Apollo moon landing program also used Triple Modular Redundancy (TMR) for failure-critical equipment). Over 50 T200 systems went into in service in 16 countries between 1972 and 2020, with a focus on Hong ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stored Program Control
Stored program control (SPC) is a telecommunications technology for telephone exchanges. Its characteristic is that the switching system is controlled by a computer program stored in a memory in the switching system. SPC was the enabling technology of electronic switching systems (ESS) developed in the Bell System in the 1950s, and may be considered the third generation of switching technology. Stored program control was invented in 1954 by Bell Labs scientist Erna Schneider Hoover, who reasoned that computer software could control the connection of telephone calls. History Proposed and developed in the 1950s, SPC was introduced in production electronic switching systems in the 1960s. The 101ESS private branch exchange (PBX) was a transitional switching system in the Bell System to provide expanded services to business customers that were otherwise still served by an electromechanical central office switch. The first central office switch with SPC was installed at Morris, Ill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overseas Telecommunications Commission
The Overseas Telecommunications Commission (OTC) was established by Australia in August 1946. It inherited facilities and resources from Amalgamated Wireless Australasia Limited (AWA) and Cable & Wireless, and was charged with responsibility for all international telecommunications services into, through and out of Australia. In effect, all overseas telecommunications was nationalized. Australia was adopting a Commonwealth-wide policy that had been adopted at the Commonwealth conference in 1945. The main goal was to end the artificial routing of traffic to cable or wireless depending on private financial profits. On 1 February 1992 it was merged with Australia's domestic telecommunications carrier, the Australian Telecommunications Corporation Limited ("Telecom Australia") to create the Australian and Overseas Telecommunications Corporation Limited (AOTC). The new organisation underwent a corporate identity review and was subsequently renamed Telstra Corporation Limited ("Tels ...

Teletex was ITU-T specification F.200 for a text and document communications service that could be provided over telephone lines. It was rapidly superseded by e-mail but the name ''Teletex'' lives on in several of the X.500 standard attributes used in Lightweight Directory Access Protocol. Overview Teletex was designed as an upgrade to the conventional telex service. The terminal-to-terminal communication service of telex would be turned into an office-to-office document transmission system by teletex. Teletex envisaged direct communication between electronic typewriters, word processors and personal computers. These units had storage for transmitting and receiving messages. The use of such equipment considerably enhanced the character set available for document preparation. Features Character sets In addition to the standard character set, a rich set of graphic symbols and a comprehensive set of control characters were supported in teletex.
