Speech transmission: Tandem Operation
Speech transmission: Tandem Free Operation (TFO)
For MS to MS calls, TFO provides optimal speech quality due to less transcoding within the end-to-end speech path. The speech quality gain will be most noticeable for the lower codec rates of AMR codec type.
对于手机打电话，由于减少端到端语音话路的编解码，TFO能提供更优化的语音质量。
In most scenarios, TFO will reduce the speech path delay.
在更多的应用场景里，TFO能减少语音话路的延迟。
TFO allows the transmission saving (together with TrFO)
TFO和TrFO一起可以节省传输。
TFO is enabler for new services (e.g. AMR-WB)
TFO能提供新服务（比如：AMR-WB）。
