CMB FPWR M/S RST PWR RUN SYN CLK MST STA Structure Introduction Structure Introduction • Controller & Maintenance Board (CMB) • CMB is a major digital board in ZXG10 B8018 (V1.00) providing interface and central control functions. CMB works in active/standby mode, to avoid interruption and give protection to the services.

  22. Structure Introduction Structure Introduction • CMB Function: • Provides eight E1/T1 interfaces. • Overall radio clock and transmission clock synchronization can be achieved by configuring CMB for overall network synchronization at background. • Provides transparent passage for external environment alarm. • Supports star, chain, tree, and ring networking at Abis interface.

  23. Structure Introduction Time Slot Switching in B8018 System

  24. Structure Introduction Structure Introduction • Implements, and reads various hardware management IDs of system includes: detect in-position indication, send control command by control link ,software reset each board in system, implement power switch of each board in system, implement power switch of each board in system. • Monitoring and control of each board running status.

  25. EIB Structure Introduction Structure Introduction • E1/T1 Interface Board (EIB) • EIB Board provides the Abis interface connecting to the BSC.

  47. New Features New Features • The main features of ZXG10 B8018 is shown below: • DTRU technology; • DPCT-dual power combining Transmission; • DDT-delay diversity transmission • 4-way diversity reception; • IRC-Interference Rejection Combining; • intelligent power on/off; • IP Abis-interface.

  48. New Features New Features • The DTRU is very flexible and can be used for several purposes . Its two TRXs, for instance, can be used separately (the same with ever)or both,both refers to by DPCT to improve the downlink and by four-way diversity to improve the uplink, they can be configured to create a super TRX.

  49. New Features New Features One DTRU can easily be used to extend coverage

  50. New Features New Features • DPCT---- Dual Power Combining Transmission: • When seeking greater cell range it is crucial to have a strong signal from the BTS to the handset. This is often referred to as downlink capability. This is what a handset presents as signal strength in the display. In configurations intended for maximum coverage, Dual Power Combining Transmission (DPCT) feature doubles the output power from the BTS cabinet, resulting in a significantly larger coverage area.
