Question: In a GSM Public Land Mobile Network (PLMN), what is the typical bitrate associated with an A interface connection element for a Full or Half rate TCH (Traffic Channel) in a Radio interface connection?
Option 1: 16.0 kbit/s
Option 2: 64.0 kbit/s
Option 3: 128.0 kbit/s
Option 4: 256.0 kbit/s
Explanation: In the context of GSM PLMN, for Full or Half rate TCHs, the A interface connection element typically operates at a fixed bitrate to ensure compatibility and efficient use of resources. Among the provided options, 64.0 kbit/s is the correct bitrate, aligning with standard practices for managing traffic between network segments in GSM architectures, supporting necessary signaling and data transfer without overburdening the network.
