Configuration Flexibility
The configuration of Metro1000 is quite flexible. Each network element can be configured 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, the transmission bandwidth and Ethernet ports can be flexibly configured according to the user's bandwidth needs, and the user's need for bandwidth can also be met without increasing the number of ports and single boards. Flexible Networking

Flexible Networking
OptiX Metro1000 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, and mesh hole.

Perfect Protection
OptiX Metro1000 supports a variety of network-level protection methods, including MSP protection, SNCP protection, PP protection, and shared fiber virtual path protection, clock protection, 1+1 protection of power supply units, and other device-level protection methods.

Flexible DCC Transmission Mode
can transmit DCC information of our equipment through external clock port; it supports DCC transmitting network management information of other company's transmission equipment; and it can also connect the network management interface to the Ethernet interface board to transmit network management information.

Full-featured Network Management System
OptiX Metro1000 and OptiX series products adopt a unified network management platform for centralized operation, maintenance, and management (OAM) to achieve circuit configuration and scheduling, and to ensure safe network operation.

Excellent SSM Management Function
OptiX Metro1000 network element clock has perfect SSM management function. Its external synchronization port can directly receive synchronization information from external timing devices, and the output port is also equipped with SSM, and it can flexibly set the bit where SSM is located in the external 2048kbit/s signal, and it can manually set the SSM information of the external 2MHz signal, which is easy to be connected to the equipment of other manufacturers, and in addition, it can set the SSM threshold of each network element, which is conducive to the management of synchronization network.

Excellent Clock Synchronization Performance
Metro1000 transmission equipment uses advanced high-precision crystals as the internal oscillator source, and adopts a special clock processing chip to ensure that its technical specifications fully comply with the requirements of 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 and external clock synchronization sources can be selected as the reference clock source; the reliable operation of the network timing system is ensured by various priority clock selection functions.
