The Nokia 1660SM is a synchronous Optical Multi Service Node (OMSN); it complies with the Synchronous Digital Hierarchy (SDH) defined in ITU-T Recommendation G.707.
The integration of SDH and WDM technology represents the chance to enhance the network capacity with no impact on the starting physical means (i.e.fibers): the presence of a wavelength grid allows the user to multiply the capacity with limited costs, if compared to the cable laying; on the other side the SDH network (specifically configured with OMSN's equipment) represents the most flexible and reliable way to handle different types of clients, both TDM and data.
A wide range of ports can be added/dropped/connected by the equipment according to the traffic type to be managed:
–2.048 Mbit/s signal (with asynchronous mapping)
Processing of unstructured and structured (ISDN-PRA) 2 Mb/s signal.
–34/45 Mbit/s
–STM-1 Electrical/Optical
–STM-4 Optical Signal
–STM-16 Optical Signal
–STM-64 Optical Signal
–OC3 Electrical/Optical
–A mixing of SDH and Data Services is possible by inserting the 4xANY board in the 1660SM subrack.
