PA-4E1G/75 Use Case
Aggregated WAN Backbone for Nationwide Retail Banking
In a nationwide retail banking environment, the PA-4E1G/75 adapter on a Cisco 7200 aggregates four 2.048 Mbps G.703 E1 circuits (75 Ω unbalanced) at each branch into a single 8 Mbps link to the data center. Outcome: delivers high-capacity, low-latency connectivity for real-time transaction processing while reducing MPLS costs and simplifying network operations.
Seamless Legacy PBX Integration with VoIP Migration
An enterprise campus uses the Cisco 7200 PA-4E1G/75 to interconnect its traditional PBX over G.703 E1 trunks to a new IP-PBX gateway without replacing existing voice infrastructure. Outcome: preserves voice quality, accelerates VoIP adoption, and minimizes capital outlay by leveraging four E1 ports for flexible channel allocation.
Mission-Critical E1 Backup for Cloud Service SLAs
A cloud service provider deploys the PA-4E1G/75 module in Cisco 7200 routers to deliver four independent E1 backup circuits alongside primary MPLS links for key enterprise customers. Outcome: ensures automatic failover with sub-50 ms switching, achieves 99.99% uptime, and protects revenue-critical applications under stringent SLAs.
