CSU/DSU role in digital networks is to?

In digital networks, a CSU/DSU sits between the service provider’s digital line and the customer’s equipment, handling two distinct roles. The CSU is the network-facing part, connecting to the provider’s line and managing the network-side functions such as framing, timing, and line interface. The DSU terminates the digital circuit and provides the DTE interface to your customer equipment (for example, the router), enabling the DTE to communicate over the line. So the DSU handles the DTE interface, while the CSU connects to the network. This division explains why the best answer states that CSU connects to the network and DSU handles the DTE interface.
