What Is the ASR-920-12SZ-IM-CC?
The ASR-920-12SZ-IM-CC is a 1RU aggregation router from Cisco’s ASR 900 Series, purpose-built for metro Ethernet, mobile backhaul, and business service edge deployments. It features 12 SFP/SFP+ ports (1G/10G), integrated timing, and Carrier Ethernet capabilities, making it ideal for service providers needing dense, low-power connectivity in space-constrained environments. The “CC” suffix denotes factory-default configurations for rapid deployment in converged cable access networks.
Key Technical Features and Innovations
- Port Density: 12x 1G/10G ports with support for Ethernet, OTN, and legacy TDM via pseudowire.
- Timing Precision: SyncE and IEEE 1588v2 ensure ±50ns accuracy for 4G/LTE and 5G fronthaul.
- Layer 2/3 Services: MPLS, QoS, EVPN-VPWS, and E-Line/E-LAN Ethernet services.
- Power Efficiency: Consumes under 60W at full load, critical for solar-powered remote sites.
Primary Use Cases and Deployment Scenarios
1. Mobile Backhaul for 4G/5G Small Cells
The router’s compact size and timing sync enable cost-effective aggregation of traffic from urban small cell deployments.
2. Enterprise Cloud Access
Supports SD-WAN integration via Cisco vManage, providing secure, SLA-driven connectivity to AWS/Azure.
3. Legacy Network Modernization
Replaces aging TDM switches using Circuit Emulation Services over Packet Switched Network (CESoPSN).

Practical Observations from Deployment
In a recent rural telecom project, the ASR-920-12SZ-IM-CC’s low power profile allowed deployment at off-grid sites using solar panels—something bulkier routers couldn’t achieve. While its 12-port limit isn’t suited for hyperscale roles, its precision timing and rugged design make it indispensable for operators balancing cost and performance at the edge. Cisco’s focus on backward compatibility ensures even older SFP modules remain viable, easing transitions from legacy infrastructure.
