ABSTRACT:
On an optical ring network side, an optical ring transmission apparatus is provided with a first ring-side TDM device and a separately implemented first packet ring device, on a first ring side. On a client network side, the apparatus is provided with a first client-side TDM device and a first packet transceiver, which are implemented separately from the devices on the optical ring network side. The devices on the client network side can be connected to the devices on the optical ring network side through a switch section including a packet switch and a TDM switch. Further, the apparatus has a dual configuration with the provision of devices that pair up with the above-mentioned devices, such as a second packet ring device. The flexibility can be ensured by the redundant configuration and the independent implementation of the devices as described above.
