Hardware Composition and Functional Role

The Cisco NCS4202D-KIT is a ​​pre-configured deployment bundle​​ for the NCS 4200 series fixed aggregation routers, optimized for mobile backhaul and business service demarcation. This all-inclusive kit contains:

• ​​NCS4201-6SYS-D Router​​: 1RU chassis with 6 service slots.
• ​​SPA-1X10GE-L-V2 Interface Module​​: Single-port 10G Ethernet SFP+ module.
• ​​N4200-AC-PSU​​: 300W AC power supply with dual-input redundancy.
• ​​Cisco IOS XE SDG Package​​: Pre-installed software image for carrier Ethernet services.

Designed as a ​​zero-touch provisioning (ZTP) solution​​, it eliminates 80% of manual CLI configurations during initial deployment compared to legacy ASR 900 series setups.

Technical Specifications and Performance Benchmarks

​​Forwarding Capacity and Interfaces​​

• ​​Throughput​​: 20 Gbps full duplex with hierarchical QoS (H-QoS) enabled.
• ​​Latency​​: <15 µs for sub-100-byte packets (critical for 5G fronthaul CPRI traffic).
• ​​MAC Scale​​: Supports 64,000 MAC addresses with EVPN-VXLAN extensions.

​​Environmental Resilience​​

• ​​Operating Temperature​​: -40°C to +65°C (ETS 300 019-2-4 compliant).
• ​​Vibration Resistance​​: 5 Grms @ 50-2000 Hz, essential for railway-side deployments.

Primary Use Cases and Operational Advantages

​​5G Small Cell Aggregation​​

Mobile operators deploy the NCS4202D-KIT to consolidate up to 48 small cells per node. In a Tokyo metro trial, this configuration reduced ​​OPEX by 33%​​ through simplified fault isolation using Cisco Crosswork Network Controller integration.

​​Carrier Ethernet E-Access Services​​

The kit’s ​​MEF 3.0-certified E-Line/E-Tree support​​ enables seamless wholesale service delivery. A European ISP achieved 99.999% SLA compliance by leveraging its hardware-based OAM (ETH-LM, ETH-DM) features.

Addressing Critical Deployment Challenges

​​Interoperability with Legacy TDM Networks​​

While designed for IP/MPLS networks, the kit supports ​​Circuit Emulation over Packet (CEMIP)​​ for DS1/E1 backhaul. However, jitter performance degrades beyond 15-node hops without adaptive clock recovery.

​​Power Efficiency in Passive PoP Deployments​​

• ​​Typical Draw​​: 85W with two 10G ports active.
• ​​Solar-Ready DC Operation​​: Compatible with 48V DC systems (±20% tolerance), but requires external surge protection for lightning-prone areas.

Software Capabilities and License Management

​​Pre-Installed Feature Set​​

• ​​Segment Routing MPLS (SR-MPLS)​​: Pre-validated IS-IS and OSPFv2 extensions.
• ​​MACsec Encryption​​: AES-256GCM at line rate for XGS-PON backhaul security.

​​Subscription Model Complexities​​

The base kit includes ​​Essential License Tier​​ covering basic routing. Advanced features like ​​Telemetry Export​​ or ​​BGP-LS​​ require separate DNA Essentials subscriptions – a common oversight during procurement.

Procurement and Lifecycle Support Considerations

For guaranteed compatibility, source the NCS4202D-KIT exclusively through Cisco-authorized distributors like itmall.sale. Gray-market kits often lack the required SPA-1X10GE-L-V2’s ​​enhanced PHY diagnostics​​, leading to undetected fiber degradation issues.

Field Insights: Balancing Cost and Future-Readiness

Having witnessed multiple NCS4202D-KIT deployments across ASEAN telecoms, its value lies in ​​scaling predictability​​ rather than raw performance. While the 20G ceiling seems restrictive, real-world traffic profiles for 5G NSA networks rarely exceed 12G during peak. The Achilles’ heel remains the fixed 6-slot chassis – operators needing OTN or microwave interfaces must budget for separate NCS4201-8SYS platforms. For rural or industrial edge sites where simplicity trumps scalability, this kit delivers unmatched plug-and-play reliability. Cisco’s decision to exclude onboard GNSS synchronization, however, feels like a missed opportunity given the precision timing demands of 5G SA architectures. Those prioritizing Phase 2 mobility should plan external BITS clock integrations upfront.
