Question: Which of the following Common Transport Channels does NOT have an associated Iub Data Port for its individual mapping?
Option 1: RACH (Random Access Channel)
Option 2: FACH (Forward Access Channel)
Option 3: BCH (Broadcast Channel)
Option 4: DSCH (Downlink Shared Channel) [TDD]
Explanation: The BCH (Broadcast Channel) is carried directly on the Node B control port using NBAP procedures and does not require an individual Iub Data Port for its mapping, unlike RACH, FACH, and DSCH [TDD] which have associated Iub Data Ports.
