Thiết bị STM 1/4 Loop O9550

The Loop-O9550 SDH/SONET IMAP (Integrated Multi-Service Access Platform) 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.


The Loop-O9550 SDH/SONET IMAP (Integrated Multi-Service Access Platform) 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. The 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. Redundancy is available in dual CPU controllers and power supply options, making the O9550 an excellent fit for critical applications. The chassis does not need or contain fan cooling, though an external fan tray is available.
 
The O9550 supports local control and diagnostics by using by using a VT-100 terminal connected to the console port. The O9550 also supports Ethernet, Telnet, SSH and SNMP so that it can also be controlled and diagnosed from remote locations. An in-band management channel with GUI is available. LED indicators for all plug-in cards are also available.
