The PA-A3-8T1IMA module offers great reliability. It supports eight T1 connections and provides high-speed, stable data transfer for our network.
We use the PA-A3-8T1IMA for its solid performance. It supports eight T1 connections, ensuring stable and fast data transfer across our network.
The PA-A3-8T1IMA has been essential for handling T1 connections. It delivers excellent performance and integrates seamlessly into our infrastructure.
This module provides reliable T1 connectivity. The PA-A3-8T1IMA offers fast, stable data transfer, helping optimize our network performance.
The PA-A3-8T1IMA is a great addition. It supports multiple T1 connections and ensures fast, stable data transfer across our network.
The Cisco PA-A3-8T1IMA is an 8-port ATM inverse multiplexer and T1 port adapter for Cisco 7200 Series routers, providing T1 circuit aggregation for high-availability WAN connectivity.
The PA-A3-8T1IMA is compatible with any Cisco 7200 Series router equipped with a Port Adapter Expansion (PAE) slot, including the 7204VXR, 7206VXR, 7211, 7213, and 7214 models.
Key features include eight T1 ports, ATM inverse multiplexing, dynamic bandwidth allocation, hardware-based QoS, and support for up to 256 PVCs per port.
The PA-A3-8T1IMA is supported on Cisco IOS Releases 12.2(8)T, 12.2(15)T, and later, with required ATM and T1 feature sets enabled.
Power down the router, insert the PA-A3-8T1IMA into an available PAE slot, secure the module with the retention screw, reconnect power, and verify with the 'show platform' command.
Each T1 port uses an RJ-48C connector; use shielded twisted-pair T1 cables terminated with RJ-48C plugs for reliable connectivity.
Each T1 port supports up to 1.544 Mbps full-duplex, with aggregate throughput capped at 12.352 Mbps across all eight ports.
The adapter supports up to 256 PVCs (Persistent Virtual Circuits) per port, enabling extensive ATM network segmentation.
The PA-A3-8T1IMA consumes approximately 12 W and operates in 0 °C to 40 °C ambient temperatures with 10%–90% non-condensing humidity.
Ideal use cases include T1 link aggregation for legacy WAN, backup connectivity for MPLS networks, and gradual migration from TDM to ATM infrastructures.
Use Cisco IOS commands under the ATM interface (for example, 'interface atm0/0 multiplex t1 inverse') and configure PVCs with 'atm pvc <vpi>/<vci> … service ppp'.
Unlike standard T1 adapters, the PA-A3-8T1IMA provides hardware ATM inverse multiplexing, eight ports in a single module, and advanced QoS capabilities.
The PA-A3-8T1IMA is covered by Cisco’s One-Year Limited Warranty and is eligible for Cisco SMARTnet® service for extended support and maintenance.
Run 'show platform hardware slot <slot> port-adapter' and 'show controllers t1' in Cisco IOS to confirm operational status, port statistics, and link integrity.
Refer to Cisco’s official website for the Cisco 7200 Series Port Adapter Installation Guide and the Cisco IOS Release Notes for ATM and T1 features.
