‘Legacy’ telecoms history
The Sagem ADR product range was an SDH Add-drop Multiplexer (ADM) product family designed as a flexible platform for Metro Access and Metro Core, backhauling, microwave radio and Utilities infrastructure networks.
The family included ADR155c and ADR622, STM-1/STM-4 ADM, and ADR2500 ‘eXtra’ and ADR10000, STM-16/STM-64 multi-service NG SDH. This range was managed by the IONOS Network Management System (NMS) which also managed Sagem Primary Multiplexers, PDH and SDH microwave radio and DWDM systems.
The ADR family was deployed worldwide with more than 60,000 units over 5 years.
Comprehensive Functionality
The ADR platform offers a large variety of interfaces from E1 and E3, Fast Ethernet and Gigabit Ethernet, enabling the provision of a wide range of end Customer services. Transmission protection for guaranteed QoS is provided with SNCP, MSP, MS-SPRing as well as common unit and tributary protection.
The STM-16 network units can be used for multi STM-1 or STM-4 and local-cross connect functionality thanks to a fully non-blocking switch matrix.
The modular and flexible housing provided by the ADR155c (2U), ADR622 (6U) and ADR2500 ‘eXtra’ (14U) 19” and ETSI subracks provide a flexible mix of office, street cabinet and equipment room deployment.
