These sequences are examples and do not provide a comprehensive set of all different scenarios.

In cases where the logical and / or transport channel for a given message is known, it can be shown in front of the message name (Logical_Ch: Transport_Ch: Message). For example: DCCH:RACH:Acknowledged Data indicates a data message on DCCH mapped onto RACH. Either logical or transport channel can be omitted, if it is unspecified for the message.
