Protection requirements

I. Overview
SDH transmission equipment_OptiX Metro1000 is a new generation of STM-1/STM-4 compatible multi-service transmission equipment, which provides STM-1/STM-4 optical synchronous transmission function, and the line rate can be upgraded from STM-1 to STM-4 on-line.OptiX Metro1000 products provide rich service interfaces and powerful crossover capability.
II. Functional Description
1. Complete optical interface series: a variety of specifications of the STM-1 optical interface a variety of specifications of the STM-4 optical interface rich auxiliary interfaces using its powerful overhead processing capabilities to provide users with a number of data interfaces: two-wire analog telephone interface, providing regeneration segment/multiplexing section of the official liaison user-definable transparent data interfaces switching input and switching output interfaces 10M Ethernet network management interface RS-232 power monitoring interface. 232 power monitoring interface.
2. Flexible Configuration: The configuration of OptiX Metro 1000 is quite flexible. Each network element can be configured either as a single STM-1/4 TM or ADM system, or as a multi-ADM system with a combination of STM-1 and STM-4 interfaces, and cross-connections between multiple systems can be realized; when accessing data services, you can flexibly configure the transmission bandwidth and Ethernet ports according to the user's bandwidth requirements, and also satisfy the user's need for bandwidth increase without increasing the number of ports and single boards. Demand
3. Flexible Networking: OptiX Metro 1000 can provide a variety of networking methods and support a variety of network topologies, including point-to-point, chain, ring, ring-with-chain, intersecting ring, tangent ring, mesh-hole shape, and so on.
III. Features and Benefits
1. Perfect protection: SDH transmission equipment_OptiX Metro 1000 supports a variety of network-level protection modes, including MSP protection mode, SNCP protection mode, PP protection mode and shared fiber virtual path protection mode, clock protection, power supply unit 1+1 protection and other equipment-level protection modes.
2. Flexible DCC transmission: it can transmit DCC information of our equipment through external clock port; it supports DCC transmission of network management information of other companies' transmission equipment; it can also connect the network management interface to the Ethernet interface board to transmit network management information.
3. Well-functioning network management system: OptiX Metro 1000 and OptiX series products adopt a unified network management platform for centralized operation, maintenance and management (OAM), which realizes circuit configuration and scheduling and ensures safe network operation.
4. Excellent SSM management function: OptiX Metro 1000 network element clock has perfect SSM management function. Its external synchronization port can directly receive external timing equipment synchronization information, the output port also has SSM, and can be flexibly set the external 2048kbit/s signal SSM where the bit, can be manually set to the external input 2MHz signal SSM information, easy to interface with other manufacturers' equipment, in addition, you can set up the SSM threshold of the network elements, in order to facilitate the management of the synchronous network.
5. Excellent clock synchronization performance: advanced high-precision crystals as the internal oscillator, and the use of special clock processing chip, to ensure that its technical indicators fully comply with the requirements of the ITU-T G.813 recommendations. The timing system can work in tracking mode, hold mode and free oscillation mode. The timing system can provide SSM function. When working in tracking mode, one of the line, branch, external clock synchronization sources can be arbitrarily selected as the reference clock source; through a variety of priority level clock selection function to ensure the reliable operation of the network timing system.
