Reply To: improve TBF drop rate


please check in the cells whether DTM function is enabled or not.

DTM is Dual Transfer Mode (DTM) function. The DTM function enables an MS to provide both the CS service and the PS service at the same time. The function requires the support of the BSC.

If this function is enabled in BSC then disable this feature and then check the next hour TBF SR definitely it improves.
