5 PCM The built-in PCM board processes PCM services, improving network reliability by minimizing device stacking and potential points of failure. In addition, the U2000 supports efficient O&M by centrally monitoring PCM services. PCM device Space saving Fewer stacked devices PCM board More reliable Fewer device faults Easy O&M Centralized management and monitoring Voice Low-rate Data Other Railway Administrative telephone, scheduling telephone, hotline telephone SCADA, signal monitoring, clock Miscellaneous services PCM Interface 2/4 wire, E&M, FXS/ RS232/RS422 V.35/V.28/V.11/X.21 2-wire/4-wire Audio and E&M Audio terminal 2-/4-wire audio STM-N/E1 2-/4-wire audio Audio terminal NE A PCM board: AT8 SDH line/pdh tributary board NE B Hotline FXS STM-N/E1 FXS PCM board NE A SDH line/pdh tributary board NE B Z Interface Extension FXS STM-N/E1 FXS PBX NE A PCM board SDH line/pdh tributary board NE B Sub-rate s Control center X.50 D3/V.110 encapsulation Sub-rate Sub-rate STM-N/E kbit/s kbit/s Controller NE A PCM board SDH line/pdh tributary board NE B

6 Multiple Layers of Protection Multiple layers of protection prevent multiple points of failure and ensure high network reliability. RBC BSC MGW MSC 50 ms Switch Core SDH error detection rate10-9 Aggregation Aggregation Layer STM-N protection: LMSP 1+1/1:1 Packet protection: PW 1:1 Access Access Layer: MPLS-TP ring, MSP, and SNCP protection to prevent multiple points of failure TPS: E1/E3/FE Ethernet service protection: LAG/DLAG Equipment Redundancy SCC/Switch/Clock/Power/ Fan 1+1 hot backup BTS/eNodeB TP-Assist TP-Assist provides packet network O&M methods that are similar to those for SDH, improving O&M efficiency. Improved troubleshooting efficiency Hierarchical performance/alarm Packet testing Meter-free Error NMS E2E service configuration Optimization using MPLS-TP to improve O&M Fast service deployment increases efficiency by up to 60%. Multiple performance indicators, alarm levels, and triggering conditions increase O&M efficiency by up to 75%.
