Role of the ASR-920-24SZ-IM in Cisco’s Edge Routing Solutions
The ASR-920-24SZ-IM is a 24-port, 1G/10G aggregation router in Cisco’s ASR 900 Series, optimized for metro Ethernet, business services, and mobile backhaul. Its hardened design and advanced Layer 3 features make it a go-to solution for service providers requiring dense, cost-effective edge deployments.
Technical Specifications and Operational Advantages
High Port Density: 24x1G/10G SFP/SFP+ ports enable scalable subscriber aggregation for broadband or wireless tower traffic.
Layer 3 Flexibility: Supports MPLS, BGP, and OSPF, allowing seamless integration into IP/MPLS core networks for end-to-end QoS.
Industrial Resilience: Operates in temperatures from -40°C to 65°C and complies with NEBS Level 3, making it suitable for unmanned cabinets or harsh environments.
Addressing Key Deployment Questions
Q: Can the ASR-920-24SZ-IM handle encrypted traffic without performance drops?
A: Yes, its hardware-accelerated IPsec ensures line-rate encryption for up to 10G interfaces, critical for financial or government networks.
Q: Is it compatible with Cisco’s SDN frameworks like Segment Routing?
A: Fully supports Cisco Segment Routing with IPv6 (SRv6), enabling automated traffic engineering and simplified WAN architectures.
Procurement and Authenticity Verification

Why Edge Aggregation Demands Precision Engineering
In deploying ASR-920-24SZ-IM routers across rural broadband projects, I’ve seen their sub-2µs latency prevent bottlenecks in high-LLQ (Low-Latency Queuing) scenarios. While its lack of redundant power supplies may seem limiting, the router’s 55W max power draw allows cost-effective UPS backups. For providers modernizing legacy TDM networks, this platform’s Ethernet-focused design eliminates the need for separate pseudowire hardware—a silent CapEx saver.
