PA-A3-8E1IMA Use Case
Aggregating Multiple E1 Circuits for High-Availability Branch Connectivity
In a global manufacturing enterprise with remote production sites, network engineers deploy the PA-A3-8E1IMA-Model:Cisco 7200 Series 8-port ATM Inverse Mux E1 (120 Ohm) Port Adapter to inverse-multiplex and bond eight independent E1 links into a single resilient ATM PVC. This setup delivers up to 16 Mbps of aggregated bandwidth with carrier-grade failover, ensuring uninterrupted SAP replication and VoIP services. Benefit: maximized throughput, seamless E1 link redundancy, and simplified QoS management for mission-critical branch operations.
Carrier-Grade ATM Service Delivery in Metro Networks
A regional telecommunications provider uses the PA-A3-8E1IMA-Model:Cisco 7200 Series 8-port ATM Inverse Mux E1 (120 Ohm) Port Adapter at its aggregation nodes to inverse-multiplex eight legacy 2.048 Mbps circuits into a single ATM cell stream. This enables delivery of multiple PVC-based services—such as IPTV distribution, leased-line replacement, and VLAN convergence—over existing copper infrastructure. Benefit: rapid service turn-up, optimized bandwidth utilization, and reduced CAPEX by leveraging in-place E1 handoffs.
Secure Disaster Recovery Link for Financial Institutions
A multinational bank establishes a dedicated DR link between its primary data center and a backup site using the PA-A3-8E1IMA-Model:Cisco 7200 Series 8-port ATM Inverse Mux E1 (120 Ohm) Port Adapter. By inverse-multiplexing eight E1s into a single AES-encrypted ATM channel, the bank ensures synchronous database mirroring and low-latency transaction replication even during peak loads. Benefit: enhanced business continuity, stringent SLA adherence, and cost-effective use of existing E1 circuits for secure financial data synchronization.

A
The PA-A3-8E1IMA is a port adapter for Cisco 7200 routers that provides eight 2.048 Mbps ATM inverse multiplexing E1 ports with 120 Ω connectivity to aggregate bandwidth and optimize WAN performance.
Q
Which routers are compatible with the PA-A3-8E1IMA module?
A
The PA-A3-8E1IMA is compatible with all Cisco 7200 Series routers that feature a PA-slot; ensure your router is running a supported Cisco IOS release before installation.
Q
What are the key benefits of using the PA-A3-8E1IMA adapter?
A
This adapter delivers increased throughput via inverse multiplexing across eight E1 circuits, reduces operational costs, simplifies deployments, and supports ATM QoS classes for guaranteed performance.
Q
How do I install the PA-A3-8E1IMA in my Cisco 7200 router?

Power down the router, align the module with an empty PA slot, slide it in until it clicks, secure the captive screws, then power the router back on and verify with the show diag command.
Q
What is ATM inverse multiplexing and why is it useful?
A
ATM inverse multiplexing splits a high-speed data stream across multiple E1 links and recombines it at the destination, effectively increasing bandwidth and providing link redundancy.
Q
What is the total aggregated throughput of the PA-A3-8E1IMA?
A
The adapter supports up to 16.384 Mbps of aggregated throughput by inverse multiplexing eight independent 2.048 Mbps E1 circuits.
Q
Which cable type is required for E1 connectivity?
A
Use 120 Ω touch-proof RJ-45 twisted-pair cables terminated to each E1 port for proper signal integrity and compliance with ITU-T G.704.
