(DSU) A component of customer premises equipment used to interface to a digital circuit combined with a channel service unit; converts a customer's data stream to bipolar format for transmission.
Simplified modem for the transmission of digital data over a private line or for limited distance communications over the PSTN, where it is not necessary to comply with all the requirements for a high speed modem.
"A device that transmits digital data on transmission facilities. Typically
A DSU/CSU is used to convert the signal carried by a Local Exchange Carrier to one that a higher level device (such as a router) can use.
A device used for interfacing data terminal equipment (DTE) to the public telephone network. A type of short-haul, synchronous-data line driver, usually installed at a user location, that connects user synchronous equipment over a 4-wire circuit at a preset transmission rate to a servicing central-office.
A customer-owned, physical layer device that terminates an access line, such as a T1, form the network. The customer's mirror image of a central office repeater. Traditionally, DSUs were network equipment used in conjunction with customer-owned CSUs to terminate access lines. See channel service unit.
(DSU) A DCE device that interprets, interfaces, and provides timing and signal control between a DTE (Data Terminal Equipment) device and a digital network.
A digital interface device that connects end user data communications equipment to the digital access lines and provides framing of sub-64 Kbps customer access channels onto higher-rate data circuits. ADSU may be combined with a CSU into a single device called a CSU/DSU. See Channel Service Unit/Data Service Unit.
A customer premises device that is used to interface to a digital circuit (DDS or T I when combined with a CSU). The DSU performs conversion of a customer's data stream to bipolar format for transmission.
