Customer Presentation

Conclusion 1. CTC = 2 shall be implemented across network. This gives 2. 3. 4. 5.

25-30% HR reduction without much impact on Data traffic DL DTx shall be implemented across network. The same gives 10-15% improvement in TCH drop and 7-10% improvement on SDCCH Drop Rate. T200S shall be increased to 780msec. The same gives 1520% improvement on SDCCH Drop Rate. RET/SLO shall be trialed at 3 more BSCs. The same shall give 10 to 15% better SDCCH Success Rate. T3122 shall be tried on BSC having high SDCCH Blocking.
