Allow E Down G Up Switch |
|---|---|
Description |
This parameter specifies whether to enable the multiplexing of EDGE download and GPRS upload onto the same channel. If this parameter is set to Open, the EDGE download and GPRS upload can use the same channel; If this parameter is set to Close, the EDGE download and GPRS upload cannot use the same channel. In dynamic allocation or extended dynamic mode, the downlink block must use the GMSK coding scheme (including CS1-4, MCS1-4) to detect the USF assigned for the uplink by the GPRS MS. Then, the downlink cannot use the high-rate coding scheme, thus decreasing the EGPRS rate. If the Allow E Down G Up Switch is set to Close, this can prevent the EGPRS downlink and GPRS uplink from multiplexing the same channel to ensure the EGPRS rate. However, the channel needs to be properly allocated, the GPRS channel configured is to prevent decreasing the access of the GPRS MS due to no GPRS channel. If the Allow E Down G Up Switch is set to Open, the downlink uses the GMSK coding scheme, thus decreasing the EGPRS rate. At present, this parameter is usually set to Open. |
