Configuration Policy |
For no call drop in ring rotating, two sets of data are recommended. It is suggested that the configuration is based on the recommended data. When the transmission quality is good, the following data is recommended: ring II waiting time before rotate(s) equals 0; ring II try rotating duration time (s) equal 60; ring II rotating penalty time (s) equals 0; T200 (10 ms) equals 12; T203 (s) equals 1; N200 (times) equals 3. When the transmission quality is poor, the following data is recommended: ring II waiting time before rotate(s) equals 30; ring II try rotating duration time (s) equal 60; ring II rotating penalty time (s) equals 0; T200 (10 ms) equals 24; T203 (s) equals 3; N200 (times) equals 3. |
