The Nokia Synfonet system is both DXC and ADM ( Digital Cross Connect and Add-Drop Multiplexer). Cards belonging to this system can be repaired at the MMX repair centre. The system subsequently became Marconi portfolio. Nokia Synfonet is early SDH and provides STM-1, STM-4 and also WDM Mux as well as 64Kbps cross connects. It has both optical and also electrical interfaces. The Synfonet system followed on from another legacy TDM system known as Nokia Dynanet.  It was deployed to play the role of Transport Node, Add- Drop Mux and Cross Connect.
