description: The Dedicated Control Channel (DCCH) is a logical channel in the radio access network used for transmitting control information between the network and user equipment. It is utilized for signaling purposes, such as sending the UECapabilityEnquiry message to request UE radio access capabilities.
explanation: DCCH is classified as a Channel because it serves as a specific path for data transmission related to control information in the context of the provided paragraph from 3GPP TS 38.331.
