ZXMP S385 SDH-Based Multi-Service Node equipment

Upswing of services poses a gigantic challenge for network bandwidth. On request by transport network evolution, multi-service transport equipments featuring large capacity, flexible dispatch, high reliability, elastic bandwidth and upgradeability are needed to handle service delivery in the core network.

Considering service diversity and variation of network architecture, inheriting ZTE’s technology patents and experience in the field of SDH and implanting new technological contents in SDH equipments, ZTE launches ZXMP S385, an intelligent STM-16/STM-64 multi-service transport platform designed advanced technology, allowing customers to build the efficient and competitive network.

Highlights

Targeting network backbone layer or large-capacity convergence layer applications, ZXMP S385 can be served as medium-capacity DXC, large-capacity ADM, while enabling Ethernet switch and ATM switch functionalities via MSTP functions. It can be flexibly configured as REG/TM/ADM/MADM when serving as ADM. It has the ability to smoothly upgrade from STM-16 to STM-64.

• Large-capacity and flexible service dispatch capability

The equipment has the ability to process multiple lines of ECCs, fully satisfying the requirements for complex networking, supporting complex network topologies, such as linear, ring, hinge, ring with chain, tangent ring and crossing ring, at levels of STM-1/STM-4/STM-16/STM-64.

• Strong multi-service access ability

ZXMPS 385 offers versatile service interfaces: STM-64/STM-16/STM-4/STM-1 optical interfaces; STM-1, E3/T3, E1/T1 (support framing processing) electrical interfaces; POS interface, ATM interface, FE/GE Ethernet interfaces and SAN interface. Multiple bearer modes like EOS, embedded RPR and embedded MPLS are available to deliver Ethernet private line (EPL), Ethernet virtual private line (EVPL), Ethernet private LAN (EPLAN) and Ethernet virtual private LAN (EVPLAN) services, addressing requirements for multiple technologies in different networking environments.

• Highly reliable and complete equipment protection

ZXMP S385 provides perfect equipment-level protection: with redundant design in hardware, dual-bus architecture is adopted in service bus, overhead bus and clock bus, resulting in a vastly improved system reliability and stability. Two cross-connect clock boards are employed to perform 1+1 protection for cross-connect clock.

1:N hardware service protection for PDH service board: 1:N (N<=9) protection for E1/T1 service board, 1:N (N≤4) protection for E3/T3, STM-1 and FE electrical interfaces.

Multiple protection modes include cabinet external power supply protection, board power supply protection and sub-rack power access protection.

• ·Perfect and intelligent network protection

ZXMP S385 supports perfect network-level protection: enabling ITU-T-recommended networking characteristics, protection modes containing: 1+1 link multiplex section protection, link 1:N protection (N=14), unidirectional path protection ring, 2-fiber bidirectional multiplex section protection ring, 4-fiber bidirectional multiplex section protection ring, dual node interconnection protection (DNI), subnetwork connection protection (SNCP), and logic subnetwork protection (LSNP).

ZXMP S385 features robust intelligence, supports automatic discovery of network topology and resource, automatic and rapid end-to-end service provision and resistance to multi-node failure in the network; its also supports multi-priority service protection and restoration policy.

• Outstanding scalability

ZXMP S385 can be smoothly upgrade to 10G system from 2.5G system. It can perform dispatch and add/drop of vast lower-order services during dispatching high-speed services. Designed with cutting-edge GFP, LCAS technologies, the system supports data/voice-oriented hybrid transmission, ensuring steady extending capabilities to dispatch and process data services.
