Why is device class identification (DCI) activated during a DOCSIS modem's initialization?

Device class identification (DCI) is primarily activated during a DOCSIS modem's initialization to prioritize different service levels after outages. When a modem starts up or reinitializes, the DCI allows the cable modem to inform the network about its capabilities and service requirements. This helps the network allocate resources effectively and ensure that the necessary bandwidth and connectivity levels are given priority to devices based on their classifications.

In scenarios such as outages, where multiple devices might attempt to reconnect simultaneously, the DCI enables the network to manage traffic efficiently and establish services in an orderly manner. This reduces the risk of congestion and ensures that critical devices receive the appropriate service levels they require right away.

The other options relate to different aspects of network management or operational efficiency but do not specifically pertain to the unique role that DCI plays during the initialization process. Enhancing security protocols, ensuring faster boot-up times, or providing user-specific customization are important but not the primary function of DCI in this context.
