A leading Tier 1 telecom operator deploys the SPA-2XT3/E3 2-port Clear Channel T3/E3 Shared Port Adapter on a Cisco ASR 9000 to seamlessly onboard legacy T3/E3 links into its IP/MPLS core. By preserving existing 45 Mbps (T3) and 34 Mbps (E3) circuits, the operator enables uninterrupted customer voice and data services during network modernization. The outcome: zero migration downtime, 30 % OPEX reduction, and carrier-grade reliability for continued revenue streams.
A multinational bank integrates its headquarters’ T3-based PBX trunks and remote E3 data links over an MPLS overlay using the SPA-2XT3/E3 adapter on Cisco ASR 9000 routers. This configuration enforces QoS prioritization for mission-critical voice traffic while consolidating data backhaul on the same platform. The result: 25 % lower connectivity costs, end-to-end encryption compliance, and sub-5 ms jitter for high-volume trading communications.
An enterprise data center implements redundant SPA-2XT3/E3 modules across dual Cisco ASR 9000 chassis to safeguard T3/E3 circuits in its disaster recovery infrastructure. Automated failover ensures uninterrupted transmission of SCADA telemetry and legacy PBX calls under network fault conditions. The deployment achieves 99.999 % uptime, seamless traffic rerouting in under 50 ms, and compliance with stringent SLAs for continuous business operations.
