Note that although the name of the AccessDB_Request command suggests only write operations are possible, there are
subcommands to read from the data base.
Each AccessDB_Request command is answered by the MODEM with either a AccessDB_Confirm or AccessDB_Error
frame.
For better readability, the AccessDB_Confirm frames and explanation are listed here and not grouped into a separate chapter.
