Nokia C08950.D5F (HWAT-A) High-Speed Signaling & Trunk Processing Board

Product Overview

Key Specifications

Core Features

1. Dedicated SS7 Signaling Processing

   
   

   Delivers high-throughput SS7 (Signaling System 7) message processing and routing, supporting thousands of concurrent signaling transactions per second. It offloads signaling workloads from the main control board to ensure low-latency call setup and teardown.
   
   
2. Abis Trunk Interface Management

   
   

   Manages multiple E1/T1 Abis trunks connecting the base station controller (BSC) to base transceiver stations (BTS), providing circuit switching and data forwarding for voice and signaling traffic.
   
   
3. Carrier-Grade Reliability

   
   

   Engineered for 24/7 uninterrupted operation in mission-critical telecom environments. Supports hot-swappable installation and N+1 redundant configuration to eliminate single points of failure.
   
   
4. Full Platform Compatibility

   
   

   Compatible with all BSC3i chassis variants including BSC3i 660, BSC3i 2000, and BSC3i 3000. Works seamlessly with all other DX200 platform boards for integrated network operation.
   
   
5. Proven Field Performance

   
   

   Deployed in millions of cells globally, the HWAT-A board has a decades-long track record of stable performance in diverse environmental conditions across all major telecom markets.

Compatibility

Exclusively Supported Platforms

• Nokia BSC3i Base Station Controllers: BSC3i 660, BSC3i 2000, BSC3i 3000
• Nokia DX200 Digital Switching Platform: DX200 MSC/VLR, DX200 BSC chassis

Interoperability

Typical Applications

• 2G/EDGE Radio Access Networks: Signaling and trunk processing for base station controllers in global GSM networks
• Legacy Network Maintenance: Replacement and spare parts for existing BSC3i/DX200 deployments
• Network Expansion: Scaling signaling and trunk capacity of 2G networks in regions where 2G services remain essential
• Rural Telecommunications: Providing reliable voice and basic data services in underserved areas with limited 4G/5G coverage

Technical Notes

• Product History: Originally developed by Ericsson, this product line was acquired by Nokia in 2016 and continues to be supported for legacy network maintenance
• Hardware Revision: The "D5F" suffix indicates the specific hardware revision of the HWAT-A board, ensuring full compatibility with all BSC3i firmware versions
• Current Status: Classified as a legacy telecom product, primarily used for maintenance and spare parts purposes. Modern networks have transitioned to 4G/5G baseband controllers
