The following diagram describes the way of handling C/I value changes. It is assumed
that the mailbox is not free as the first change was detected. After releasing the mailbox
by the µP the DELIC sends the C/I values and their IOM-2 channel addresses. The
preceding change on channel 6 will not be reported.
