PA-4E1G/120 Use Case
Enterprise WAN Aggregation with Cisco 7200 PA-4E1G/120 for Remote Branch Connectivity
In a multinational enterprise, IT teams deploy the PA-4E1G/120 adapter in Cisco 7200 Series routers to terminate up to four balanced 120Ω E1 G.703 links from regional carriers. This configuration aggregates 8 Mbps of dedicated bandwidth per router, simplifies cabling and circuit management, and delivers carrier-grade failover. The outcome is consistent, secure WAN performance and 99.99% uptime across distributed office locations.
Telecommunications Carrier VoIP Migration Using Cisco 7200 and PA-4E1G/120
A service provider integrates legacy TDM voice trunks into its next-generation IP network by installing PA-4E1G/120 in Cisco 7200 gateways. Each adapter handles four G.703/E1 120 Ω circuits, enabling seamless migration of up to 240 simultaneous voice channels. Benefits include reduced capital expenditure on proprietary gateways, accelerated roll-out of VoIP services, and preservation of existing E1 infrastructure with end-to-end QoS assurance.
Industrial SCADA Backbone over E1 G.703 with Cisco 7200 PA-4E1G/120
A utility operator connects remote substations and PLC clusters to its central SCADA server via dedicated E1 G.703 links using the PA-4E1G/120 module in Cisco 7200 routers. The balanced 120 Ω ports ensure noise-immune transmission over long copper runs, while built-in adaptive clock recovery minimizes jitter. The result is deterministic telemetry, real-time control, and compliance with critical infrastructure reliability standards.
