CSSR Is Degraded?
Immediate Assignment Is degraded? SDCCH Drop analysis is similar to TCH Drop analysis: 1.Check Interference possibility. 2.Check HW Issue Possibility. 3.Check Transmission Issues Possibility 4.Check External Interference issues. 5.Check Coverage Issues

.Check Immediate Assignment Per TRX for the RXs that contains SDCCH.
.Check the DL/UL Quality for the TRX that ontains the SDCCH Channel.
.Check Unbalance, Alarms and Main/Diversity ifference to make sure no HW Issue
