h1. Ericsson RBS 6000 architecture The Ericsson RBS 6000 architecture consists of many different modules, roughly split into two parts: * Digital Unit (baseband) * Radio Unit (ADC/DAC/PA/Duplexer/Diversity/...) The two units are interconnected via [[CPRI]] using SFP Transceivers (typically fiber optic based). As far as we know, for GSM the CPRI line speed is 2.5Gbps. A single Digital Unit can drive multiple Radio Units (typically up to 6). h1. GSM support in RBS6xxx h2. Digital Unit * [[DUG 10]] (Digital Unit GSM) for up to 12 TRX using [[RUG]] * [[DUG 20]] (Digital Unit GSM) for up to 12 TRX using [[RUS]] or [[RRUS]] * [[DUS 30]] for up to 12 TRX using [[RUS]] or [[RRUS]] * [[DUS 31]] for up to 24 TRX using [[RUS]] or [[RRUS]] (12 TRX in mixed mode LTE + GSM) * [[DUS 41]] for up to 48 TRX using [[RUS]] or [[RRUS]] (12 TRX in mixed mode LTE + GSM) h2. Radio Unit * [[RUG]] (Radio Unit GSM) for 2 GSM TRX * [[RUS]] (Radio Unit SDR) for 4 GSM TRX (or 3G/4G with DUW/DUL) * [[RRUS]] (Remote Radio Unit SDR) for 4 GSM TRX (or 3G/4G with DUW/DUL)
