Question: What is the primary focus of the specification regarding UTRAN interfaces?
Option 1: Control Plane Protocol for Common Transport Channel Signaling
Option 2: User Plane Protocol for Dedicated Transport Channel Data Streams
Option 3: Management Plane Protocol for UTRAN Network Configuration
Option 4: Security Protocols for UTRAN Interface Authentication
Explanation: The correct answer accurately reflects the focus on specifying user plane protocols, responsible for transferring user data over Dedicated Transport Channels in UTRAN networks. This ensures efficient and reliable data transmission between the Radio Network Controller (RNC) and Node B, highlighting its importance in telecom network operations for dedicated channel communications.
