Reply To: Repeated FACH/SACH


hi vang

repeated facch – better outgoing ho efficiency rate
repeated sacch – less call drop rate “amr”

that would be very visible in cells where usage of lower codecs is high. This usage can be assessed through RMS indicators.

could you tell me what is your subset of codecs AMR FR ?

The repeated FACCH or SACCH should not have any impact on TFO.

TFO with AMR… there should be an increase on the number of TFO requests in your network. I don’t know what are the names of the indicators, but all the ones which contain the string ‘TFO’ will definitely reflect the change.

There should be more AMR codec changes, as a result. So here again, you might see such effect in the RMS.
