Customer Premises Equipment (CPE) refers to the devices and equipment located on the customer's property that connect to a service provider's network. This includes items like routers, modems, and telephones, which enable communication and data transfer between the customer and the service provider. CPE is essential for services such as internet, telephony, and television. It allows users to access these services effectively, ensuring a seamless experience. Service providers often install or rent CPE to customers, ensuring compatibility with their network infrastructure.
