R9008: OUT_OF_STEP_NUM
This measurement provides the number of times that the PDCHs are out of synchronization in a granularity period.
Integer number or integer.
Every time the PDCH is out of synchronization, the counter is incremented by one. The reason why the PDCH is out of synchronization may be the transition of the BTS frame number, change of the transmission delay, PS cell reset, or BTS reset.
This is an original counter without involving any formula.
