Caution |
When this parameter is used: 1. "Level of Preempting Dynamic Channel" must be set to "No preempt of service TCHF"; otherwise this parameter is invalid. 2. The number of TCH/F of current TRX must be more than the value of the Reservation Threshold of Dynamic Channel Conversion parameter. 3. "Maximum Ratio Threshold of PDCHs in a Cell" must be set properly; otherwise the TCH/F can not be changed to the PDCH because of the low ratio. 2 and 3 are optional. |
