Customer service unit

In telecommunication, a customer service unit (CSU) is a device that provides an accessing arrangement at a user location to either switched or point-to-point, data-conditioned circuits at a specifically established data signaling rate.

Note: A CSU provides local loop equalization[?], transient protection, isolation, and central office loop-back testing capability.
