Protected Multi-Station Ring Connectivity
High capacity ring protection for multi-station connectivity
Protected ring connectivity for mission-critical applications such as automatic train supervision (ATS), centralized traffic control (CTC), positive train control (PTC), SCADA, multi-party hotlines, and passenger information systems (PIS) between stations and control rooms.
Self-healing, multi-rate TDM and Ethernet ring (RFER – resilient Fast Ethernet ring) solutions with rapid sub-50 ms restoration that provides NSPF (no single point of failure) resiliency. Use multiservice multiplexers, single box devices for all communications needs at each location.
- Under-50 ms restoration ring solutions for NSPF (no single point of failure) resiliency
- High ring granularity at E1/T1 or VC-12/VT-1.5 level allows bandwidth optimization over copper, dark fiber and SDH/SONET
- Hybrid Ethernet and TDM architecture for smooth and cost-effective migration from TDM to PSN
- Carrier-grade Ethernet ensures service performance and ongoing KPI monitoring
