Alcatel 1660 SM
The 1660 SM Optical Multi-Service Node (OMSN) comprises next-generation STM-16/64 SDH equipment that integrates packet-switching functionality into a capable SDH system. It can be configured as a pure add-drop multiplexer or as a small cross connect. It provides STM-1/4/16/64 ports and a 384×384/256×256 STM-1 equivalent HO/LO matrix.
Meeting both metropolitan and regional network requirements, the 1660 SM is an ideal multiservice transport building block for delivering SDH, integrated ATM and Packet Ring MPLS-based switching capabilities, as well as LAN interfaces (Ethernet, Fast Ethernet and Gigabit Ethernet). Integrated Service Adapter (ISA) modules designed for ATM or Packet Ring switching and Ethernet or Gigabit Ethernet transport through the optical network can be equipped as needed. The 1660 SM supports Generalized MPLS (GMPLS) for enhanced resiliency and flexible service interworking with intelligent optical core networks, such as those based on the 1678 MCC.
The main network applications of the 1660 SM are: SDH metro transport in both ring and meshed network architectures; Backhauling of 3G mobile and DSL broadband traffic; Metro Ethernet in MAN and WAN; SANs.
The 1660 SM offers an AU3/TU3 conversion feature to support SONET/SDH gateway capabilities (for cost-effective transportation and aggregation of non-concatenated SONET payloads) when OMSNs are deployed at the SONET/SDH boundaries.
It provides unmatched performance for its footprint.
The 1660 SM also allows for flexible and cost-effective Storage Area Network (SAN) and transparent data services, spanning SDH and WDM technologies.
