1.   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.

2.   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.

3.  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.

4.  Perfect and intelligent network protection
1) 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).
2) 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.

5.  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.

7.  Sound design, easing operation and maintenance

1) ZXMP S385 supports mixed insertion of boards, easing service configuration and network planning & optimization. System operation adopts front-facing interfaces, easier for maintenance.
2) ZXMP S385 employs pluggable optical modules (SFP module, LC connector) and supports ALS functions; various optical boards and boards share spare parts, driving down cost. It supports online optical power detection for all optical interfaces, facilitating rapid location of line failure and boosting maintenance efficiency.
3) Highly integrated equipment results in lowered expenditure for space; low power consumption reduces electricity expense.
