BTS3006C Traffic Signal FlowThe DL signal flow includes the following steps:
The DMCM receives the service data from the BSC, exchanges and processes it,and then transfers it to the DDRM
The DDRM performs digital filtering, up conversion, and filter amplification of thesignals and sends the signals to the DDPM
The duplexer in the DDPM filters the signals sent from the DDRM and transmits
the signals through antennas and feedersThe UL signal flow includes the following steps:
The antenna receives the signals transmitted from the MS., then signals aretransmitted to the DDPM
The DDPM receives the signals and transmits the signals to the DDRM after theyare filtered by the duplexer and amplified by the LNA
The DDRM receives the signals and transmits the signals to the DMCM afteramplification and down conversion. The DMCM then transmits the signals to theBSC through the Abis interface

BTS3006C Clock Signal Flow
The clock signal flow includes the following steps:
The external reference clock is transmitted to the clock module inthe DMCM through the Abis interface
The clock module performs phase lock and frequency division on
the clock signals to generate different clock signals for BTSsThe clock signals are transmitted to the modules in the basiccabinet such as the DDRM and the DDPM
The clock signals are transmitted to the modules in the extensioncabinets through the clock distribution cable
