Medium Access Protocol (MAC)

This protocol is the layer 2 protocol of the UTRAN Iub interface between a Node-B and an RNC. For instance, it maps logical channels (BCCH, PCCH, DCCH, ...) to transport channels (PCH, FACH, RACH, ...). The protocol and its functions are specified in 3GPP TS 25.321.

The MAC dissector is partially functional (it only supports FDD, not TDD mode). Dissection is possible for RACH, FACH, PCH, DCH, E-DCH and HSDSCH.

To correctly dissect frames, the MAC dissector requires per-frame information on whether or not a C/T MUX field is present and what kind of content the frame contains. At the moment, this information can be generated by using the FP Hint protocol.
