The CSU, or Channel Service Unit, is a device used in digital telecommunications to connect end-user equipment to a digital circuit, such as a T1 line. Its primary functions include signal conditioning, line monitoring, and providing an interface between the local network and the carrier's network. The CSU helps to ensure that the data transmission remains reliable and meets the necessary standards by managing issues like voltage levels and line integrity. Additionally, it often includes diagnostic capabilities to troubleshoot connectivity issues.
