channel service unit
<communications> (CSU) A type of interface used to connect a terminal or
computer to a digital medium in the same way that a modem is used for connection
to an analogue medium.
A CSU is provided by the communication carrier to customers who wish to use
their own equipment to retime and regenerate the incoming signals. The customer
must supply all of the transmit logic, receive logic and timing recovery in
order to use the CSU, whereas a digital service unit DSU performs these
functions.
