Superior service access capability enabling eased and flexible service provision Optical interfaces contain STM-16/4/1 interfaces, electrical interfaces contain STM-1, E3/T3, E1/T1 TDM service interfaces. Offer agile service add/drop, EOS functions are available in full support of data service models including EPL, EVPL, EPLAN, EVPLAN, accommodating customers demands for delivering high bandwidth data services, Use embedded-RPR based on flexible logic subnetwork technology to build RPR ring, and the unique RPR span-ring feature breaks up the single ring restriction in RPR networking, Perfect QoS control enables traffic configuration based on IP priority, DSCP priority, TOS priority, COS priority and port priority, Provide embedded ATM function, support VP-VC switch, CAC control, CC, and PVC 1+1 protection. Comprehensive and perfect protection capability ensuring highly reliable network ZXMP S330 offers 1+1 redundant protection for critical boards, such as clock board, cross-connect board. The system provides 1:Nredundant protection for service interfaces to protect E1/T1/E3/T3/FE/STM-1 (E) electrical tributaries. Single sub-rack can protect 4 groups of electrical tributaries simultaneously. ZXMP S330 employs dual power distribution system, all functional boards adopt distributed power supply mode, with little impact on power supplies among boards, and greatly erasing the effect on system during plugging/unplugging boards. ZXMP S330 has ITU-T-recommended networking characteristics. Protection modes include 1+1 multiplex section protection, 2-fiber bidirectional multiplex section protection ring, 4-fiber bidirectional multiplex section protection ring, dual node interconnection protection (DNI) and sub-network connection protection (SNCP). ZXMP S330 can also offer protection for data service layer. It supports Ethernet shared protection ring, RPR ring protection and ATM 1+1 protection. Reliable timing synchronous processing capability boosting synchronous network performance ZXMP S330 employs advanced phase locked circuit, with synchronization to external clock, line clock and E1/T1 tributary clock for option. The system provides tributary re-timing function for E1 interface. The system support synchronous priority switching and SSM-based automatic switching, optimizing network timing and synchronization distribution, lowering the difficulties in synchronization planning, avoiding timing loop and ensuring to keep network synchronization the optimal state. Eased maintenance & upgrade and lowered OPEX System operation adopts front-facing interfaces, easing maintenance. Separation of service interface board and processing board enables customer to select and replace interface board types on site according to service demands. Support online 2.5G optical power detection, facilitating rapid location of line problem and improving maintenance efficiency. High level of integration results in small footprint, low power consumption leads to reduced electricity charge.
