to the earth complies with the standard requirements.
The working grounding and protection grounding of the BTS and the
surge protection grounding of the building share one group of grounding
conductors.
The grounding grids of the tower, equipment room, and distribution
transformer (if the distance between the transformer and the equipment

The connectors of the E1 cables are tight and secure.
The connectors of the E1 cables are intact.
The E1 cables or RF cables are not damaged or broken.
The connectors of the RF cables are fixed in position to prevent the
possible false connection from causing abnormal voltage standing wave
ratio (VSWR).
The horizontal RF cables are clamped to the cable trough.
The proper cable surpluses are reserved at the connectors.
All cables are neatly bound with ties installed at even intervals, to a proper
tightness, and in the same direction.
