The Loop-O9400R STM-1/4/16 (OC-3/12/48) is a standards-compliant high density NGN SDH/SONET ADM/TM with a full T1/E1 cross-connect rack system. The O9400R has full add and drop capability according to below:

  • For controller STM-1/4 (OC-3/12) aggregate cross connect module, up to 1 STM-4 tributary
  • 8 STM-1 tributaries
  • 18 E3/T3 tributaries
  • 378 E1/T1 tributaries
  • 48 10/100M Ethernet EoS tributaries
  • 6 GbE EoS tributaries
  • For controller STM-1/4/16 (OC-3/12/48) aggregate cross connect module, up to: 4 STM-4 tributaries
  • 16 STM-1 tributaries
  • 24 E3/T3 tributaries
  • 504 E1/T1 tributaries
  • 64 10/100M Ethernet EoS tributaries
  • 8 GbE EoS tributaries
  • 56 FOM tributaries

With up to 4 STM-1/4/16 (OC-3/12/48) aggregate interfaces on cross-connect modules and 16 STM-1 (OC-3) interfaces on tributaries, the Loop-O9400R offers the service provider a a versatile protection scheme including SNCP (UPSR), and MSP (1+1) protection for both ring and linear network topology.

All interfaces are fully compliant with the relevant ETSI standards and ITU recommendations. The Loop-O9400R provides powerful Operation, Administration, Maintenance and Provisioning (OAM&P) functionality, including fault management, performance monitoring, configuration management, and network security management. Through a console port, LAN port, In-band E1, and DCC channel, the OAM&P can be achieved both locally and remotely via SNMP or menu-driven interfaces.

The Loop-O9400R provides a complete set of operation interfaces that are consistent with the Telecommunication Management Network (TMN) concept (ITU Recommendation M.30, G.784) for SDH/SONET Network Element/Operations System (NE/OS), NE/NE, and NE/Craft communications. Users can easily operate the Loop-O9400R locally or remotely for centralized management.
