  1. Passport architecture

  2. Unit objectives In this unit, you will • describe the component administration system (CAS) • define components, attributes and instances • using the list and display commands, create a component instance tree (CIT) with component associations • use the V-O-C-A command syntax with verbs and wildcarding • know the security levels of network management interface system (NMIS) • discuss network synchronization.

  3. Spoolers Agents Collectors On-switch management system Active CP FP NMIS CAS Applications External interfaces: FMIP Telnet LocalFTP External interfaces FTP Note: Applications and agents also reside on the CPs. Interfacing to them is the same as shown for the FPs. Requests/Responses Event data Data collection system

  4. External interfaces Component administration system Active CP • component model is OSI-based • provides common functionality across applications • all applications are treated as components and are named using a component hierarchy • provides a common interface to all components CAS CAS NMIS DCS Functionprocessor Applications

  26. Network clock synchronization (NS) Module clocking source Function Processor Passport node Stratum 4 clock Receive signal Control Processor Port/x Transmit signal Stratum 3 clock Dual buses

  27. CP Stratum 3 clock Rx signal comes from a more accurate Stratum 1 clock source. Therefore the Tx uses the more accurate source. Function processor Transmission equipment Stratum 4 clock Receive signal Stratum 1 Port/x Transmit signal uses the Stratum 1 clock Network clock synchronization (continued) FP Receive signal Local clocking source Port/x Transmit signal Stratum 4 clock Line clocking source
