    PASOLINK Network Management System for UNIX

    The PASOLINK Network Management System (PNMS) is designed to bring comprehensive, easy-to-use and cost-effective management to the integrated microwave network environment. A user-friendly graphical interface together with a set of integrated tools enable the network operators to

    remotely monitor and control the status and configuration of the entire PASOLINK and PASOLINK+

    network.

    This UNIX based system also provides monitoring of the live microwave link performance, easy

    viewing of various radio parameters, and advanced alarm management.

    FEATURES AND BENEFITS

    Multi-layer Display

    Starting at the root level, by clicking on theselected item (icon), the tree-structured displayscan be viewed in a subsequent manner. Thisfeature enables the network administrator toquickly view the network from a system-levelperspective.

    Link Oriented Visualization

    The microwave radio links are clearly visualizedon the display. Combining equipment status withkey parameter settings and performance data forboth sides of a microwave link in a singlewindow allows easy troubleshooting and efficientmaintenance work.

    Remote Access

    Whether at the central or a remote site, access

    to any network element (NE) in the network isseamlessly connected through one of the servicechannels.

    Standard Platform

    For ease of operation and maintainability, theUNIX operating system is employed as theplatform for the central management software(PNMS) and Windows 2000/NT/98/95

    operating

    system is the platform for the software at the NEsite (PNMT).

    SYSTEM OVERVIEW

    The PASOLINK Network Management System comprises three elements, a high performancecomputer with peripheral equipment, a software package called PASOLINK Network managementsystem (PNMS) and PASOLINK Management Card (PM CARD, only for PASOLINK) to be equippedin the PASOLINK equipment.

    The PNMS is located at a central or a regional operation center and enables network operators tomonitor and control the PASOLINK / PASOLINK

    +network and its elements remotely. Alternatively, a

    laptop computer with simplified software package, called PASOLINK Network Management Terminal(PNMT) is available for maintenance purpose.

    A PASOLINK/PASOLINK+

    NE at the central site interfaces with the PNMS through one of thefollowing interfaces.

    - PASOLINK : RS232C 19.2/9.6kbps, Async (through Router)

    - PASOLINK+

    :10BASE-T(LAN) or V.11 19.2kbps, Async (through Router)

    Communication to the Remote PASOLINK/ PASOLINK+

    is established through one of the digitalservice channels in the network.

    KEY COMPONENTS

    PNMS

    Sun Workstation with its peripheral equipmentand UNIX operating system is used to support

    PNMS software.

    It provides a central access point to monitor andcontrol the entire network remotely. The PNMSsoftware provides map viewing of the entirenetwork as well as its individual subnetworks.

    The PNMS provides means to edit, upload, anddownload the configuration files to each of the

    PASOLINK / PASOLINK+

    network elements.

    Multi-level access privileges are implemented toensure the security of the system.

    PNMTA mobile terminal such as of a laptop PCrunning Windows 2000/NT/98/95 Operatingsystem containing a simplified version of thePASOLINK Network Management softwarecalled PNMT, is provided for maintenancepurpose.

    This configuration can monitor and control a

    single PASOLINK / PASOLINK+

    link at a time.

    Any link through the network, connected via

    digital service channel, can be monitored andcontrolled remotely from the laptop.

    PM Card (only for PASOLINK)

    The PASOLINK Management Card (PM CARD)is an optional plug-in module for NEC'sPASOLINK Indoor equipment.

    The PM CARD handles the communicationbetween the PASOLINK network elements andthe Network Management system. It collects upto 300 event logging data and up to seven daysof performance data.

    The PM CARD can either connect permanentlyor occasionally to the NMS. The PM CARDcommunicates with each other via one of theservice channels. It serves as a single accesspoint and enables the remote access to anyPASOLINK in the network.

    (The PM Card function is incorporated in the

    PASOLINK+.)

    BASIC FUNCTIONS -PNMS-

    Status Monitoring and Display

    The PNMS monitors the status of the

    PASOLINK / PASOLINK+

    stations by way of

    polling mechanism. Detection of a status changeor failure to report at one of thePASOLINK/PASOLINK

    +stations will result in a

    color change on the display and if appropriate, inan audible alarm.

    The multi-level windowing structurecorresponding to different map levels provideseasy guidance to pinpoint to the PASOLINK /

    PASOLINK+

    station of the concern and

    subsequently to its components.

    For ease of operation and quick reference, thePNMS automatically displays the status of the

    opposite PASOLINK / PASOLINK+

    station with

    its key link parameters.

    As shown in the figure to the right, key

    components of PASOLINK / PASOLINK+

    such

    as the outdoor unit (ODU), indoor unit (IDU) andthe PASOLINK Management Card (PM CARD,only for PASOLINK) are distinguished. Thedetailed information for each of thesecomponents can be found in the subsequent

    windows.

    Remote Control

    The PNMS software provides remote control ofvarious link related parameters such as transmitpower and frequency allocation.

    Auxiliary Input/OutputSix photo-coupler input ports and four relayoutput ports are available in the PASOLINK /

    PASOLINK+ equipment to allow monitoring andcontrolling of the miscellaneous equipment atsite.

    The types of alarm and control for these portscan be defined freely by the operator.

    BASIC FUNCTIONS -PNMS-

    Performance Monitoring

    The PNMS is able to retrieve the performance

    data of all listed PASOLINK / PASOLINK+

    stations and their associated microwave linkequivalent to ITU-T G.826 recommendation.For that purpose, the following performanceparameters are measured:

    (For PASOLINK)- Errored Second Ratio (ESR)- Severely Errored Second Ratio (SESR)- Unavailable Seconds Ratio (UASR)- Background Block Error Ratio (BBER)

    (For PASOLINK+

    )

    - Errored Second(ES)- Severely Errored Second (SES)- Unavailable Seconds (UAS)- Background Block Error (BBE)- Out of Frame Seconds (OFS)

    Thresholds can be defined in each parameter tosignal an alarm when a performance objectivehas failed.

    The performance monitoring display is availablein either a chart or a graph format for a selected

    period of time.

    Security

    PASOLINK Network Management Systememploys high security measure to protect thenetwork and network management system fromunauthorized access. Ten levels of userprivileges are defined.

    The highest level is the administrator level whichassigns the full access to the network and

    network management system and has the abilityto create and assign privileges to other users.

    Privileges differ in the extent of access to a

    certain PASOLINK / PASOLINK+

    groups and

    stations and in the extent of right of control andconfiguration initiation.

    Privilege settings include:- Monitor of individual PASOLINK/ PASOLINK

    UPPER MANAGEMENT INTERFACE (OPTIONAL)

    In order to make NEC's PASOLINK / PASOLINK+

    equipment an integral part of an upper

    management system, an optional SNMP interface is provided with the PNMS. The interface is basedon SNMPv1 and resides on the same WS as the PNMS. The detailed control and data gathering areperformed by the PNMS. The summarized alarm traps (Summary SNMP trap such as Group of NE

    summary trap or NE summary trap) are notified to upper management system through this interface.

    The optional X-terminal can be connected to the PNMS through LAN interface using X-protocol. Thenetwork operator can use an X-terminal to perform almost all the functions of the PNMS. In case ofupper management system receives summary traps from PNMS, the operator need to access PNMSwindow on X-terminal for the detail.

    In addition, as each PASOLINK / PASOLINK+

    also has SNMP interface in itself, each PASOLINK/

    PASOLINK+

    is directly accessible from upper management system if required.

    The interface to the upper management is UDP/IP with Ethernet interface. Even though the LANinterface is pre-configured by the work station, 10BASE-x are assumed.
