About This Part
The Siemens 612-404/38 Tributary Card is a critical component designed for the SRAL XD series of microwave radio systems. In telecommunications, a tributary card serves as an interface module, aggregating various lower-speed or different-format client signals—such as E1/T1, STM-1, or Ethernet traffic—and preparing them for transmission over the main, higher-capacity radio link. This card ensures seamless integration and efficient multiplexing of diverse data streams, enabling the SRAL XD system to handle a wide range of communication services. Typical use cases for the Siemens 612-404/38 TRIB CARD include expanding the capacity and versatility of existing microwave backhaul networks. It allows network operators to integrate new services or increase bandwidth for existing ones without a complete system overhaul. While specific technical specifications for this exact part number (612-404/38) are proprietary to Siemens SRAL XD systems, its function is to provide the necessary physical and logical interfaces for client-side connectivity, ensuring robust and reliable data transport across the radio link. Revo Distribution Limited proudly offers used and refurbished Siemens 612-404/38 TRIB CARDs to support the operational continuity and longevity of telecom infrastructure. By providing access to high-quality, tested refurbished equipment, Revo enables B2B clients to maintain and upgrade their Siemens SRAL XD systems cost-effectively.
