This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels. The distinction can be arbitrary between a computer bus, often closer in space, and larger telecommunications networks.
The TU81 was a dual-density, 9-track, ANSI standard 1/2-inch magnetic tape subsystem built and sold by Digital Equipment Corporation. The tape drive appeared under TU81, TU81 Plus, and TA81 model designations. The main difference between the TU81 and TA81 models was the communications interface.
With the mass production of the integrated circuit (IC) the tape measure has also entered into the digital age with the digital tape measure. Some incorporate a digital screen to give measurement readouts in multiple formats. An early patent for this type of measure was published in 1977. [23] There are also other styles of tape measures that ...
T1 is a protocol for digital transmission over telephone networks. A T1 circuit combines 24 DS0 channels through time-division multiplexing. Data is transmitted in frames, where each frame contains an 8-bit sample of each of the 24 channels, plus one extra framing bit for a total of 193 bits. Each channel carries 8,000 samples per second.
G.703 is a ITU-T standard originally written in 1972 [1] but subsequently revised a number of times since. It defines a physical and electrical interface used for encoding voice or data over 75 ohm co-axial cable terminated in BNC or Type 43 connectors or 120 ohm twisted pair cables terminated in RJ48C jacks.
