PA-A3-8T1IMA Use Case
Enterprise WAN Bandwidth Aggregation with Cisco 7200 Series 8-Port ATM Inverse Mux
A multi-site enterprise integrates eight T1 lines via the PA-A3-8T1IMA adapter on Cisco 7200 routers to create a single high-throughput ATM circuit. This deployment boosts WAN bandwidth by up to 12 Mbps, optimizes application performance, and reduces per-Mbps costs through inverse multiplexing.
Retail Chain High-Availability Connectivity Using T1 Inverse Multiplexing
A nationwide retail chain deploys the PA-A3-8T1IMA module at each store to aggregate and load-balance multiple T1 circuits over an ATM backbone. The solution delivers seamless failover, ensures uninterrupted POS transactions, and strengthens network resilience with sub-second link recovery.
Service Provider Layer-2 VPN Delivery with Cisco 8-Port ATM Inverse Mux
An ISP leverages the Cisco 7200 Series 8-Port ATM Inverse Mux T1 Port Adapter to combine eight customer T1s into a dedicated ATM PVC for Layer-2 VPN services. This approach guarantees committed bandwidth, simplifies provisioning, and enables stringent SLA enforcement for wholesale and enterprise customers.
