A digital cross-connect system (DCS or DXC) is a piece of circuit-switched network equipment, used in telecommunications networks, that allows lower-level TDM bit streams, such as DS0 bit streams, to be rearranged and interconnected among higher-level TDM signals, such as DS1 bit streams. DCS units are available that operate on both older T ...
Digital cross connect system. Recent digital cross connect systems (DCSs or DXCs) support numerous high-speed signals, and allow for cross-connection of DS1s, DS3s and even STS-3s/12c and so on, from any input to any output. Advanced DCSs can support numerous subtending rings simultaneously.
An optical cross-connect ( OXC) is a device used by telecommunications carriers to switch high-speed optical signals in a fiber optic network, such as an optical mesh network . In the 1980s, when transmission speeds supported by optical fibers increased from 45mb to 2.5gb, carrier networks developed and introduced digital cross connects to ...

The T-carrier is a hardware specification for carrying multiple time-division multiplexed (TDM) telecommunications channels over a single four-wire transmission circuit. It was developed by AT&T at Bell Laboratories ca. 1957 and first employed by 1962 for long-haul pulse-code modulation (PCM) digital voice transmission with the D1 channel bank .
Digital access carrier system (DACS) is the name used by British Telecom (BT Group plc) in the United Kingdom for a 0+2 pair gain system. Two Telspec DACS remote units mounted on a pole Usage [ edit ]
The Palm TX. A personal digital assistant ( PDA) is a multi-purpose mobile device which functions as a personal information manager. PDAs have been mostly displaced by the widespread adoption of highly capable smartphones, in particular those based on iOS and Android, and thus saw a rapid decline in use after 2007.
Digital Signal 3. 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.
