What is the purpose of device class identification (DCI) in a modem?

The purpose of device class identification (DCI) in a modem is to define special modem classes for prioritization. This feature allows service providers to categorize modems based on their capabilities and performance characteristics. By identifying the class of a modem, the network can prioritize traffic and optimize the handling of data based on the type of device in use. This is particularly important in ensuring that different levels of service can be managed effectively to provide the best possible experience for users, especially in environments with varying levels of demand or different types of applications. Prioritization based on DCI helps in managing bandwidth effectively, ensuring that higher-priority traffic is handled appropriately.
