Rockwell T-1 Communication Chip Silicon Wafers - R8050, R8060, 4", 100mm

About this Artwork: Introduced in the 1960s, AT&T's T-1 carriers were the first high-speed, long-distance digital communications lines. The T-1 would allow 24 64Kbs data channels to be transmitted over two phone company twisted copper wire pairs. The total bandwidth was 1.5Mps. In the 1980s and 1990s, T-1s were the basic building blocks of the Internet. In the early 1980s, Rockwell introduced the first LSI computer chips that dramatically reduced the number of devices needed and the costs required for building T-1 transmitting and receiving equipment. T-1 Serial Transmitter - Rockwell R8050 The R8050 formatted data streams to be serially transmitted according to T-1 specifications. It inserted bits to create frames for the data and address one of the 24 available channels. T-1 Serial Receiver - Rockwell R8060 The R8060 received the T-1 data stream. It then extracted data from the frames and reassembled the original data streams. It was also responsible for detecting data transmissi
