The Loop-O9500R SDH/SONET IMAP (Integrated Multi-Services Access Platform) is an economical STM-1/4/16 (OC-3/12/48) access multiplexer designed to provide integrated access to STM-1/4/16 (OC-3/12/48) 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 LS modules.
The 6U shelf supports:
 4 HS tributary module slots
 6 LS tributary module slots
With controller STM-1/4 (OC-3/12) up to 10 optical STM-1 (OC-3) or 5 optical STM-4 (OC-12) or 10 electrical STM-1 (OC-3) line interface, the Loop-O9500R 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; as well as with
controller STM-1/4/16 (OC-3/12/48) up to 12 optical STM-1 (OC-3) or 6 optical STM-4 (OC-12) or 12 electrical STM-1 (OC-3) line interface. The O9500R 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 such as GFP, LAPS, VCAT, LCAS, and non-LCAS. These HS modules are identical to those used in the rack version of the Loop-O9400.
