The DS technically refers to the rate and format of the signal, while the T designation refers to the equipment providing the signals. In practice, "DS" and "T" are used synonymously; for example, DS1 and T1, DS3 and T3. [1]
Digital Signal 1 (DS1, sometimes DS-1) is a T-carrier signaling scheme devised by Bell Labs. [1] DS1 is the primary digital telephone standard used in the United States , Canada and Japan and is able to transmit up to 24 multiplexed voice and data calls over telephone lines.
Uniden was established on February 7, 1966, by its founder Hidero Fujimoto as "Uni Electronics Corp". Uniden became a well-known brand in the 1970s by manufacturing and marketing millions of citizens band radios (CB), under the Uniden brand as well as other companies such as Midland and Realistic, which rebranded the equipment under their own labels.
SONET and SDH, which are essentially the same, were originally designed to transport circuit mode communications (e.g., DS1, DS3) from a variety of different sources, but they were primarily designed to support real-time, uncompressed, circuit-switched voice encoded in PCM format. [1]
Strictly speaking, a DS1 is the data carried on a T1 circuit, and likewise for a DS3 and a T3, but in practice the terms are used interchangeably. There are other data rates in use, e.g., military systems that operate at six and eight times the DS1 rate.
DS3 service is provided to businesses in the United States through incumbent local exchange carrier and competitive local exchange carrier communication providers. The price, much like a T1 (or DS1) line, has two primary components: the loop (which is distance-sensitive) and the port (or the price the carrier charges to access the internet through their proprietary network).
