DSU/CSU (Data Service Unit/Channel Service Unit) Related Entries Web Links New/Updated Information Note: Many topics at this site are reduced versions of the text in "The Encyclopedia of Networking and Telecommunications." Search results will not be as extensive as a search of the book's CD-ROM. A DSU (data service unit) is a communication device that connects a company's telephone premises equipment to digital communication lines, such as a T1. A CSU (channel service unit) provides line termination and signal regeneration. The DSU and the CSU are often combined in one device and connected to a channel bank, which provides analog-to-digital conversion and multiplexing of voice transmissions.
