| 9 | 4 | laforge | The power connector is the same type as is used for the [[DUG 20]] or [[DUL 20]]: https://www.te.com/usa-en/product-1982299-3.html |

| 11 | A jumper cable with this connector on both sides is called RPM 777 193/xxxxx (where xxxxxx is the length in mm). |

| 19 | 3 | laforge | h3. Front-Haul interface (CPRI) |
| 20 | |||
| 21 | These look like SFP connectors, but are not. They are of a special connector type, but have the same electrical signaling. |
||
| 22 | |||
| 23 | We presume Ericsson did this so you cannot easily use a RUS remotely by plugging in a SFP transceiver for fiber optic transmission. |
||
| 24 | |||
| 25 | Instead, you have to use special copper CPRI cables from Ericsson: RPM 777 211/xxxxx where xxxxx is the length in mm. |

| 29 | h3. RF |
||
| 30 | |||
| 31 | 7 | laforge | The antenna connection is on a 7/16 type connector; it serves both Rx and Tx due to the internal duplexer. |
| 32 | |||
| 33 | Thre are miscellaneous RXA / RXB connectors which are presumably used in diversity applications or if multiple radios are used in the smae sector. |
