Abstract:
An optical network termination apparatus, comprising:an optical-side transmission and reception circuit with connections for connection to an optical access network; a user-side transmission and reception circuit with connections for two-way signal communications with a user network having a user terminal; a main signal insertion circuit connected intermediate the optical-side transmission and reception circuit and the user-side transmission and reception circuit; a first reception buffer connected to an output of the user-side transmission and reception circuit, the first reception buffer configured to buffer information, having a set address from the user network, via the user-side transmission and reception circuit and through the main signal insertion circuit, back into the user network; a second reception buffer connected to said optical-side transmission and reception circuit, the second reception buffer configured to buffer information moving from the optical access network, via the optical-side transmission and reception circuit and through the main signal insertion circuit, into information having the set address to the user network; a hardware CPU communication format converter connected to outputs of the first and second reception buffers; a main signal communication format converter operatively connected to an output of the CPU communication format converter, an output of converter being operatively connected to an input of the main signal insertion circuit; and a storage medium device in communication with the CPU communication format converter and the main signal communication format converter, wherein, the signal communication format converter and the main signal communication format converter are configured to read an external storage medium, removably inserted in the storage medium device to obtain an address as the set address, a monitor signal with data received from the user network received at the user-side reception and transmission circuit is i) sent through the first reception buffer to the CPU communication format converter to hardware convert the monitor signal data to a CPU communication format with the set address, ii) the main signal communication format converter converts the converted monitor signal data to a main signal communication format and sends the monitor signal data converted to the main signal communication format to the main signal insertion circuit for iii) return, via the user-side reception and transmission circuit, to the user network, and a transmission signal with data received from the optical access network received at the optical-side reception and transmission circuit is i) sent through the main signal insertion circuit and the second reception buffer to the CPU communication format converter to convert the transmission signal data to the CPU communication format with the set address, ii) the main signal communication format converter converts the converted transmission signal data to the main signal communication format and sends the transmission signal data converted to the main signal communication format to the main signal insertion circuit for iii) return, via the user-side reception and transmission circuit, to the user network.
