and the transmission process of the second signal can be as follows: part of the second signals are from the second equipment accessed by the female base type access module at the downstream, the line sequence switching module, the gain module, the first transmission switching module, the first equipment accessed by the female base type access module at the upstream, and the other part of the second signals are from the second equipment accessed by the female base type access module at the downstream, the second transmission switching module and the first equipment accessed by the female base type access module at the upstream.
