A Digital Signal 3 (DS3) is a digital signal level 3 T-carrier. It may also be referred to as a T3 line. The data rate for this type of signal is 44.736 Mbit/s (45 Mb). DS3 uses 75ohm coaxial cable and BNC connectors. This level of carrier can transport 28 DS1 level signals within its payload. This level of carrier can transport 672 DS0 level ...
Subsequent specifications carried multiples of the basic T1 (1.544 Mbit/s) data rates, such as T2 (6.312 Mbit/s) with 96 channels, T3 (44.736 Mbit/s) with 672 channels, and others. Although a T2 was defined as part of AT&T's T-carrier system, which defined five levels, T1 through T5, [ 1 ] only the T1 and T3 were commonly in use.
Transmission rates are defined by rate of the bitstream of the digital signal and are designated by hyphenation of the acronym OC and an integer value of the multiple of the basic unit of rate, e.g., OC-48. The base unit is 51.84 Mbit/s. [2] Thus, the speed of optical-carrier-classified lines labeled as OC-n is n × 51.84 Mbit/s.

Trunking. In telecommunications, trunking is a technology for providing network access to multiple clients simultaneously by sharing a set of circuits, carriers, channels, or frequencies, instead of providing individual circuits or channels for each client. This is reminiscent to the structure of a tree with one trunk and many branches.
In 2006, T3 was announced by the government and was the largest of the three public releases, reducing the government's ownership of Telstra to 17%. [10] The 17% remainder of Telstra was placed in Australia's Future Fund , a sovereign wealth fund established mainly to meet future liabilities for payment of superannuation to retired federal ...
Trading turret. A trading turret or dealer board is a specialized telephony key system that is generally used by financial traders on their trading desks. Trading has progressed from floor trading through phone trading to electronic trading during the later half of the twentieth century with phone trading having dominated during the 1980s and ...
The SECS/GEM is the semiconductor's equipment interface protocol for equipment-to-host data communications. In an automated fab, the interface can start and stop equipment processing, collect measurement data, change variables and select recipes for products. The SECS (SEMI Equipment Communications Standard)/GEM (Generic Equipment Model ...
