Huawei OptiX OSN500 03052119 21E75 S1.1 DC MSTP OSN500 SDH Transmission Equipment

High Availability, Low Power Consumption, and Compact Structure

The OptiX OSN 500 is a device used at the access layer, which features high availability, low power consumption, and compact structure. The OptiX OSN 500 supports:

• Network-level protection such as tunnel automatic protection switching (APS), PW APS, Multiple Spanning Tree Protocol (MSTP), Ethernet ring protection switching (ERPS), link aggregation group (LAG), Multi-Link Point-to-Point Protocol (ML-PPP), linear multiplex section protection (LMSP), and link-state pass through (LPT), to improve equipment reliability

• A maximum power consumption of 100 W, and a typical power consumption of only 35 W

• Dimensions (H x W x D) of 44 mm x 442 mm x 220 mm, and installation in a cabinet (including ETSI and 19-inch cabinets), on a wall or desk, or in an open rack

Pure Packet Architecture and Multi-service Transmission

The OptiX OSN 500 supports service bearing in the PTN domain. This solution evolves based on the service changes that take place due to radio mobile network evolution. Therefore, this solution can meet the transmission requirements of not only 2G and 3G networks, but also the future LTE and 4G networks. Specifically, the OptiX OSN 500 can process and transport ATM, Ethernet, MPLS, and MPLS-TP services.

End-to-End Service Configuration, One-Click Commissioning, and One-Click Fault Locating (TP-Assist)

Compared with legacy TDM networks, PTN networks have the following characteristics in terms of O&M:

• Lack of as many overhead bytes that indicate physical states of networks as TDM networks. When a fault occurs on a PTN network, no visual and fast indicator is available to locate the fault.

• Networking diversity and complication, which require powerful O&M capabilities

To address these issues, the equipment uses the TP-Assist to provide more O&M means and simplify O&M operations for PTN networks during installation, commissioning, service configuration, fault locating, and routine maintenance. With the TP-Assist, PTN networks have the SDH-like O&M capabilities, which reduce the technical requirements for O&M personnel and improve O&M efficiency.
