Overview of the A9K-48X10GE-TEL-BN Module

The Cisco A9K-48X10GE-TEL-BN is a high-density 10 Gigabit Ethernet (10GE) line card designed for the Cisco ASR 9000 Series Aggregation Services Routers. Built for telecom and service provider networks, this module supports ​​48 ports of 10GE connectivity​​ with Layer 2 and Layer 3 capabilities, optimized for bandwidth-intensive applications like mobile backhaul, metro Ethernet, and cloud-scale networking.

Key Technical Specifications

• ​​Port Density​​: 48x SFP+ ports (10GE) for scalable deployments.
• ​​Forwarding Capacity​​: Up to 480 Gbps throughput, leveraging Cisco’s Quantum Flow Processor architecture.
• ​​Layer 2/Layer 3 Features​​: Supports MPLS, QoS, IPv4/IPv6, and Carrier Ethernet protocols (e.g., MEF-compliant E-LINE/E-LAN).
• ​​Hardware Redundancy​​: Hot-swappable design with field-replaceable components to minimize downtime.

Addressing Core User Concerns

​​Q: Is this module compatible with existing ASR 9000 chassis?​​
Yes. The A9K-48X10GE-TEL-BN works with all ASR 9000 chassis variants (ASR-9901/9904/9910/9922), provided the chassis has an available slot and supports the required IOS XR software version.

​​Q: How does it handle latency-sensitive traffic?​​
The module integrates ​​hardware-based QoS​​ and granular traffic prioritization, critical for VoIP and real-time video services.

Deployment Scenarios and Use Cases

• ​​Mobile Backhaul​​: Aggregates 4G/5G cell site traffic with low jitter and high reliability.
• ​​Metro Ethernet Expansion​​: Delivers scalable E-LINE/E-LAN services for enterprise customers.
• ​​Disaster Recovery​​: Supports sub-50ms failover with MPLS Fast Reroute (FRR).

Purchasing and Compatibility Notes

For telecom operators seeking verified, cost-effective sourcing, the “A9K-48X10GE-TEL-BN” is available here. Ensure compatibility with your ASR 9000 chassis and verify IOS XR version requirements before deployment.

Final Perspective: Why This Module Matters

The A9K-48X10GE-TEL-BN addresses two critical needs in modern networks: ​​scalability without compromising performance​​ and ​​future-proofing for 5G/cloud transitions​​. Its ability to consolidate multiple services onto a single platform reduces operational complexity, making it a strategic investment for carriers prioritizing long-term agility. While newer 100GE/400GE options exist, this module remains a workhorse for networks requiring dense 10GE connectivity at a proven price-to-performance ratio.
