OptiX 2500 + (Metro3000) STM-16 MADM / MSTP optical transmission system (hereinafter referred to as the OptiX 2500 +) device is a multi-service transport platform (MSTP) equipment. The device will SDH / ATM / Ethernet / DWDM technology integration; Not only SDH equipment and flexible networking and service scheduling capability (MADM), and Layer 2 data services, ATM / Ethernet service access, processing, transmission and scheduling in a single device multiple services such as voice, data transmission and processing.

Features
     

High-capacity, multi-rate, multi-protocol access

Higher order cross Metro3000 system capacity to 128 × 128 VC4, low-level cross capacity of 2016 × 2016 VC12, according to VC-12, VC-3 or VC-4 level cross-connect ports business subrack has 96 STM-1 access capability. (REG / TM / ADM / MADM) any combination of the various modes of operation, to ensure that the system has good compatibility design and expansion capabilities. System can access data services: Ethernet interfaces, ATM interfaces, and support for N * 64k service interface V.24/V.35/X.21 other service access and aggregation business of small particles access and aggregation, provide more solutions for operators of the DDN network optimization and base station monitoring information transfer.

Powerful MADM, flexible networking and configuration capabilities

Quite flexible Metro3000 system configuration Each NE can be configured as a single STM-4/STM-16 TM or ADM system can also be configured for STM-1, STM-4, STM-16 interface combinations MADM system can realization of cross-connections between the multiple system, and having the ability to transition from the TDM traffic to data services smoothing. The system uses a large-scale cross-connect matrix and robust software design, the MADM self-healing ring network to provide fast and reliable network protection, while distributed scheduling with centralized scheduling features of the original business to full The cross ability MADM completed together to reduce the complexity of the network structure. Equipment to meet a variety of network topologies, including point-to-point, linear, ring, mesh shaped complex network and large network networking need, and can also be used as the MAN edge access layer aggregation and transmission business achieve complex network deployment and routing of integrated business protection.
    
 Tricyclic unity
 

MSTP platform-based design: the embedded RPR technology, while achieving a physical loop RPR ring, SDH ring, ATM, VP ring three logical loop shared ring network bandwidth, to achieve the full ring network bandwidth statistical multiplexing.
     

Encapsulation protocol optional mapping particles adjustable

Ethernet veneer GFP / LAPS / PPP Three package agreement, setting you can select the desired package through network management protocols. Various manufacturers encapsulation protocol of the same case, this feature greatly enhance the interoperability of the network.
The Ethernet board to provide VC12/VC3/VC4 mappings particles and map the particle number can be flexibly adjusted. This feature fully meet the needs of the customers dynamically adjust the bandwidth of data services.

 Offers a variety of Ethernet business model
 

Ethernet card provides a variety of Ethernet business application modes: transparent transmission, aggregation, the ring network sharing mode; widely used mode of aggregation can achieve: FE-> FE, FE-> GE, GE-> GE business needs fully meet our customers' business needs.
    

Ethernet port aggregation strongest
Ethernet card provides FE businesses maximum 24:1, 48:1 convergence of the GE business, the strongest specifications in the industry. Port aggregation capability of the networking capability of the device, so that the user's investment costs to a minimum. In particular, for the conduct of private line services, port aggregation ability, the stronger, the more to save ports, thus saving the user's investment.
      

Close to the customer's full data capabilities
Embedded RPR LCAS Link Capacity Adjustment Scheme, CAR Committed Access Rate, the key features of the Ethernet floor of the exchange, enhance business processing capabilities to improve business QOS. Equipment and provide full ATM functionality to meet the business needs of the whole data.
     

The Metro3000 provide comprehensive business protection system:

 Device-level protection:
 Key unit (cross, clock, power supply) support 1 +1 hot backup equipment protection;

TPS protection:
 Support 1.5M/2M/34M/45M/155M 1: n slip protection and support 2M 155M mixed with 1: n protection (n <= 8). TPS protection of the passive protection becomes active protection, make an inventory of assets, improve network security.

Network-level protection:
2F/4F MSP, PP, SNCP, DNI, shared fiber virtual path protection;

Shared fiber virtual path protection:

Virtual path protection using optical fiber in accordance with the logic subsystem by sharing, in order to improve the SDH network survivability and bandwidth resource utilization, about to each fiber bandwidth resources in accordance with VC4 units of any division, respectively to different logical sub-classified system, each logical subsystem can be selected independently in accordance with the characteristics of the transmission business a different way of protection, such an optical fiber can simultaneously support a variety of protected business to get the best protection.

Network-level link layer service protection:
ATM VP-Ring protection for ATM ring network business to ensure reliable transmission, enhance network survivability; RP-RING protection for Ethernet ring network business, enhance network survivability.

Physical characteristics:OptiX 2500 + equipment installed in the ETSI 600mm cabinet.
