SPA-2XOC3-ATM Use Case
Metro ISP Backbone Aggregation with SPA-2XOC3-ATM Shared Port Adapter
An Internet Service Provider integrates the SPA-2XOC3-ATM-2-port OC-3c/STM-1 ATM Shared Port Adapter into its regional edge router to terminate two 155 Mbps SONET circuits and support up to 256 PVCs. This setup enables tiered subscriber services with strict QoS enforcement and dynamic bandwidth allocation. Outcome: scalable 155 Mbps backbone aggregation, end-to-end SLA compliance, and optimized circuit utilization for reduced OPEX.
Enterprise Data Center Interconnect for Synchronous Replication
A global enterprise deploys the SPA-2XOC3-ATM-2-port OC-3c/STM-1 ATM Shared Port Adapter to provision dedicated ATM circuits between its primary and disaster-recovery data centers. Deterministic bandwidth, sub-2 ms path protection, and secure PVCs deliver real-time database replication and sub-second failover. Outcome: 99.999% link availability, predictable latency, and robust high-speed disaster-recovery capabilities.
Low-Latency Financial Trading Connectivity over ATM/SONET
A financial trading firm installs the SPA-2XOC3-ATM-2-port OC-3c/STM-1 ATM Shared Port Adapter to host constant bit-rate (CBR) OC-3c circuits for its algorithmic trading network. The adapter provides microsecond-level latency, minimal jitter and segregated PVC channels for order flow isolation. Outcome: superior trade execution performance, stringent compliance with exchange SLAs, and sustained competitive advantage.
