    The Loop-O9500 SDH/SONET IMAP (Integrated Multi-Services Access Platform) is an economical STM-1/4 (OC-3/12) access multiplexer designed to provide integrated access to STM-1/4 (OC-3/12) optical lines. Access is provided through either a non-blocking VC11/VC12/VC3/VC4 cross-connect with HS modules or through an additional non-blocking DS0 cross-connect fabric with low-speed access tributary modules.

    The 6U shelf supports:
    • 4 HS tributary module slots
    • 6 LS tributary module slots

    With up to 10 optical STM-1 (OC-3) or 5 optical STM-4 (OC-12) or 10 electrical STM-1 (OC-3) line interfaces, the Loop-O9500 SDH/SONET IMAP offers service providers a versatile protection schemes including SNCP (UPSR) and MSP (1+1) protection for both ring and linear network topologies. The O9500 can work with the Loop-O9100 and Loop-O9400 in the same topology.

    The non-blocking VC11/VC12/VC3/VC4 cross-connect capability on High Speed (HS) is up to 20 VC4. The HS tributary modules include optical STM-1/4 (OC-3/12), E3/T3, E1/T1 interfaces and Fast Ethernet over STM-1/4 (OC-3/12). Fast Ethernet signals are mapped onto STM payload through standard techniques GFP, LAPS, VCAT, LCAS, and non-LCAS. These HS modules are identical to those used in the rack version of the Loop-O9400.

    The uplink non-blocking DS0 cross-connect to HS is up to 21 E1 or 28 T1. The non-blocking DS0 cross-connect capability on Low Speed (LS) is up to 768 DS0. Through a full non-blocking DS0 cross-connect and together can act as a mini DACS. The modules include variety of TDM, IP, and voice interfaces detailed on next page. All LS modules are identical to those used in rack version of the Loop-AM3440.

    All interfaces are fully compliant with the relevant ETSI standards and ITU recommendations. The O9500 SDH/SONET IMAP provides full Operation, Administration, Maintenance and Provisioning (OAM&P) functionality.

    Users can easily operate the O9500 locally or remotely for centralized management with LoopView Element Management Systems (EMS) and Loop-iNMS (integrated Network Manamgement System).
