second Uplink SACCH block is skipped; value 2 corresponds to the interval of
1920 ms, so 3/4 received SACCH blocks are skipped.
3GPP TS 45.008 briefly mentiones this parameter in table A.1 (P_Con_INTERVAL).
3GPP TS 45.008 briefly mentions this parameter in table A.1 (P_Con_INTERVAL).
A small time graph is depicted below for better understanding of the meaning of
values for this parameter, since it is not obvious at all.
