3 | The Ericsson RBS 6000 architecture consists of many different modules, roughly split into two parts: |
||
4 | * Digital Unit (baseband) |
||
5 | * Radio Unit (ADC/DAC/PA/Duplexer/Diversity/...) |
||
6 | |||
7 | 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. |
||
8 | |||
9 | A single Digital Unit can drive multiple Radio Units (typically up to 6). |

||
16 | * [[DUG 20]] (Digital Unit GSM) for up to 12 TRX using [[RUS]] or [[RRUS]] |
||

18 | 1 | laforge | * [[DUS 30]] for up to 12 TRX using [[RUS]] or [[RRUS]] |
19 | 2 | laforge | * [[DUS 31]] for up to 24 TRX using [[RUS]] or [[RRUS]] (12 TRX in mixed mode LTE + GSM) |
20 | * [[DUS 41]] for up to 48 TRX using [[RUS]] or [[RRUS]] (12 TRX in mixed mode LTE + GSM) |

||
25 | * [[RUS]] (Radio Unit SDR) for 4 GSM TRX (or 3G/4G with DUW/DUL) |
||
