O9550 SDH/SONET IMAP - Integrated Multi-Service Access Platform
O9550 is an economical STM-1/4 (OC-3/12) access multiplexer.

It is designed to combine digital access interfaces, including TDM, IP, and voice interfaces into STM-1/4 (OC-3/12) optical lines for convenient transport and switching. This unit is a full cross-connect; one or more of the WAN ports can be used as a Drop & Insert function with fractional E1/T1 lines, which can be muxed into a full E1/T1 line.
O9550 provides two optical line signals at STM-1 (OC-3) or STM-4 (OC-12) with protection schemes including MSP (1+1) and SNCP protection in both ring and linear network topologies.
