OptiX155/622HMetro1000 is an STM-1/STM-4/STM-16 class box device developed by Huawei Technologies Co. It can access multiple service types and is applied to the access layer of metro and local transmission networks for large-customer private line access and DSLAM access. The hardware introduction of the device includes the box, slot distribution, various types of single boards and power conversion system. Single boards with packet characteristics are provided, which can superimpose packet plane on TDM plane to realize data transmission on dual planes and achieve the purpose of smooth evolution of TDM network to packet network. Device-level, network-level and clock protection, introduced OptiX 155/622H more complete protection mechanism. It supports tracking multiple clock sources and supports clock synchronization under SSM management. At the same time, OptiX 155/622H supports 1588 V2 time synchronization and meets the IEEE 1588 V2 recommendation. Supports the realization of multiple service networking forms in dual-plane to meet the needs of various application scenarios. Supports unified management of out-of-band DCN and in-band DCN. Supports the interaction of network management information through different data transmission modes.The SCB crossover module of OptiXMetro1000 supports a high-order crossover capacity of 21.25G (136×136 VC-4) and a low-order crossover capacity of 5G (32×32 VC-4).

The indicator descriptions on the front of the box cover several sections such as indicator name, indicator status, and meaning. The box indicator descriptions are shown in Table 1.
