CSU/DSU hardware device (Channel Service Unit/Data Service Unit)
Known fully as a Channel Service Unit/Data Service Unit, a CSU/DSU is meant to function as a device that connects routers to a T1 line. The CSU works by connection to a telecom network and the DSU handles the interface with the Data Terminal Equipment, or DTE.

CSU and DSU
• A CSU/DSU terminates a digital local loop.• A modem terminates a digital local loop.• A CSU/DSU terminates an analog local loop.• A modem terminates an analog local loop.• A router is commonly considered a DTE device.• A router is commonly considered a DCE device.
The DSU provides a modem-like interface between the computer as Data Terminal Equipment (DTE) and the CSU. The Data Service Unit (DSU) manages line control, and converts input and output between RS-232C, RS-449, or V.xx frames from the LAN and the time-division multiplexed (TDM) DSx frames on the T- carrier line it will also manage timing errors and signal regeneration. The Channel Service Unit (CSU) receives and transmits signals from and to the WAN line and provides a barrier for electrical interference from either side of the unit. The CSU can also echo loopback signals from the phone company for testing purposes.
