Parameter Name |
TCH/H Uplink DTX |
|---|---|
Description |
This parameter specifies whether to allow the MS that seizes a half-rate TCH to use the uplink Discontinuous Transmission (DTX) function. For details, see GSM Rec. 05.08. The DTX function is implemented on the basis of the following basic functions: voice activity detection (VAD), silence descriptor (SID), and comfort noise. The BSC6000 controls whether to enable the downlink DTX function. For details, see the description of the HR Use Downlink DTX parameter. |

The DTX function allows a transmitter to stop power transmission in the case of no voice transfer. This function has the following benefits: 1.On the uplink: decreasing the power consumption of the MS and reducing system interference 2.On the downlink: decreasing power consumption of the BTS, reducing system interference, and reducing intermodulation inside the BTS 3.From the network perspective, the inter-frequency interference is reduced and the network quality is improved. TCH/H Uplink DTX is not restricted by the MSC.It is allowed MS to use DTX when this parameter is set to " Shall Use". It is not allowed MS to use DTX when this parameter is set to " May Use" or " Shall not Use". |
