* Future Option 		Description

The Omniswift OT5 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 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 LS modules.

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

With up to 4 aggregate optical STM-1/4 (OC-3/12) or 4 aggregate electrical STM-1/OC-3 line interfaces, the Omniswift OT5 SDH/SONET IMAP offers service providers a versatile protection scheme including SNCP(UPSR) and MSP(1+1) protection for both ring and linear network topology. Omniswift OT5 can work with the OT1 and OT4 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 OT4.

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 MUX64.

All interfaces are fully compliant with the relevant ETSI standards and ITU recommendations. Omniswift OT5 SDH/SONET IMAP provides full Operation, Administration, Maintenance and Provisioning (OAM&P) functionality.

Users can easily operate Omniswift OT5 locally or remotely for centralized management with Omniswift View (EMS) and iNMS (integrated NMS).
