Channel Service Unit/Digital Service Unit (CSU/DSU): Hardware devices used in digital telecommunications to connect the end customer’s equipment with the public switched network. A CSU/DSU translates the digital signals produced by the customer’s equipment into signals that can be transmitted over the carrier’s network and vice versa. These devices are essential for enabling reliable data transmission over digital communication lines such as T1 and T3 connections.
