KembaraXtra-Computer Terms – Bell communications standards:
Bell communications standards refer to a group of data transmission specifications developed by AT&T during the late 1970s and early 1980s. These standards defined how modems communicated over telephone lines and were widely adopted across North America, eventually becoming de facto standards for early modem communication systems.
Examples include the Bell 103 standard, which supported transmission speeds of 300 bits per second using frequency-shift keying for full-duplex asynchronous communication. Another standard, Bell 212A, enabled communication at 1200 bits per second using phase-shift keying. Although these standards were widely used, international recommendations later developed by telecommunications organizations gradually replaced them as the primary standards for higher-speed modem communication.
