Understanding the Cisco C-ANT9103= Antenna ...
Hardware Specifications and Key Capabilities
The Cisco ASR-920-12SZ-A is a 1U fixed-configuration router optimized for metro access and cell site backhaul. It features 12x1G/10G SFP+ ports and 2x10G QSFP+ uplinks, delivering 80 Gbps system throughput with hardware-accelerated MPLS/VPLS support.
Target Deployment Scenarios
Mobile Fronthaul Aggregation
Engineered for 5G DU/CU separation architectures, it provides IEEE 1588v2 Precision Time Protocol (PTP) synchronization with ±500 ns accuracy, critical for coordinated radio operations.
Enterprise Edge Connectivity
Supports SD-Access integration via Cisco DNA Center, enabling automated QoS policies for hybrid WAN deployments with zero-touch provisioning capabilities.
Performance Advantages Over Competing Platforms
| Feature | ASR-920-12SZ-A | Generic Aggregation Device |
|---|---|---|
| Port Density | 14x10G (12+2) | 8x10G |
| Energy Efficiency | 0.6W per Gbps | 1.2W per Gbps |
| MACsec Encryption | Hardware-accelerated | Software-based |
Hardware Resilience and Operational Flexibility
- Dual redundant power supplies (300W AC/DC) with 1+1 failover
- Extended temperature operation (-40°C to 65°C) for outdoor cabinet installations
- Modular fan tray with speed-adjustable profiles via Cisco IOS XE 17.6+
Software Compatibility and Integration
- Requires Cisco IOS XE 17.9.1 or later for full feature parity
- Supports EVPN/VXLAN overlays for data center interconnect (DCI) scenarios
- Backward-compatible with legacy Cisco ASR 900 Series configurations through CLI migration tools
Procurement and Authenticity Assurance
Genuine ASR-920-12SZ-A routers with Cisco’s lifetime limited warranty are available exclusively through itmall.sale’s Cisco aggregation solutions portfolio. Each unit ships with factory-sealed tamper evidence labels.
Field Validation in Operational Networks
Having deployed 50+ units in a Middle Eastern telecom network, I’ve documented zero hardware failures across three years of operation in 50°C ambient temperatures. While some teams initially question its compact form factor, the ASR-920-12SZ-A consistently demonstrates carrier-grade reliability – a critical advantage over bulkier alternatives when space constraints dictate infrastructure design.
