OptiX 155/622H Metro1000, as an access layer device, can be mixed with Huawei's Metro series devices and OSN series devices for networking, and supports flexible networking modes such as point-to-point, linear, ring, hub, and mesh, etc. It can realize Ethernet service networking based on packet plane overlaid on TDM network. The OptiX 155/622H can realize packet-plane-based Ethernet service networking overlaid on TDM networks, and as an access layer device, it can be mixed with Huawei's Metro and OSN series devices, supporting flexible networking modes such as point-to-point, linear, ring, hub, and mesh. It supports high-order cross-capacity of 21.25G and low-order cross-capacity of 5G, and can be configured as multiple TM (Terminal Multiplexer), ADM (Add/Drop Multiplexer), or MADM (Multiple Add/Drop Multiplexer) systems, as well as supports service scheduling and protection among multiple systems, which greatly enhances the equipment's performance. It also supports service scheduling and protection between multiple systems, which greatly enhances the networking capability of the equipment and the scheduling capability of inter-network services. The access/aggregation/core layers all contain two independent planes (TDM and packet plane). In the access layer, it includes the TDM service ring (i.e., SDH ring whose maximum rate is STM-1/4) and the packet data service ring (i.e., GE ring). At the aggregation/core layer, the TDM service ring (i.e., SDH ring with a maximum rate of STM-16/64) and the packet data service ring (i.e., 10GE ring) are included. The E1 services at the access layer are first mapped to the SDH ring at the access layer (i.e., the STM-1/4 service ring in the figure), and then aggregated to the SDH ring at the aggregation/core layer (i.e., the STM-16/64 service ring in the figure) through the aggregation node. The FE services of the access layer are first aggregated to the packet data service ring of the access layer (i.e., the GE ring in the figure), and then aggregated to the packet data service ring of the aggregation/core layer (i.e., the 10GE ring in the figure) through the aggregation node.
