求翻译：如果此设备内设置FXO模块，接口为FXO口，可以将交换机过来的电话线插入此口，如果此设备内设置FXS模块，接口为FXS口，可以直接插入电话机。是什么意思？

If this device is to set the fxo module interface fxo port, you can switch over the telephone cable into this port, if this device set fxs module, interface port fxs, can be plugged directly into the phone.

If you set up in this device for FXO FXO module, interface port, you can switch from the telephone line plugged into this port, if you set up in this device for FXS FXS module, interface port, you can directly into the phone.

If in this equipment establishes the FXO module, the connection is the FXO mouth, may the telephone line which comes the switchboard insert this mouth, if in this equipment establishes the FXS module, the connection is the FXS mouth, may insert the telephone directly.

If this device sets the FXO modules, interfaces for the FXO port, you can switch over the phone cord is inserted into the mouth, set if the device FXS modules, interfaces as FXS port can be plugged directly into a telephone.
