   An external computer operating with Radio Service Software (RSS) can override data in CP data through SC. Sophisticated RSS which considers changing sizes of blocks A and/or B can replace the complete data in CP at one time. This is, however, not wanted by the customer. Instead, the RSS should update only a single block (e.g., only block A by enlarging it) and keep the content of the other block(s) (e.g., block B) unchanged. This is especial- ly important since blocks A and B are often provid- ed by different manufacturers wh...
