| 130 | not respond with the full tree (we have to query all parameters) |

| 132 | the eNodeB is transmitting (OpState=true) |
| 133 | - Parameters such as band capability/duplex config |
| 134 | are rooted under `boardconf.` and not the device config root |
| 135 | - Parameters like Admin state, CellReservedForOperatorUse, |
| 136 | Duplex mode, DL bandwidth and Band capability have different |
| 137 | formats from Intel-based Baicells units, necessitating, |
| 138 | formatting before configuration and transforming values |
