NEC for managementof NECs Pasolink and Pasolink+ radio transmission network. The PNMT is a scaled down version of Pasolink Network Management System (PNMS) that is designed as a maintenancetool for field engineers to locally and remotely monitor alarms, control points, generate repots, and archive data, all within a familiar graphical user interface, and all in real time. The PNMT is a Mobile laptop computer fitted with NEC PNMT software package that interfaces andcontrols NEC PASOLINK series short haul radio equipment.This Windows-NT/98 based software package remote monitors and controls the status and configuration of an entire PASOLINK network with associated equipment as well as the performance of the actual microwave links.1.2Conventions Used in this Manual- 1 -FontWhat the Font RepresentsExampleItalicFor manual titles or related document names.Please refer to Pasolink OperationManual for details.HostnameBoldItems on the user interface.

The Windows operating system is employed which is capable of multi-task processing using the Pentium microprocessor. The PNMT software basically consist of two parts, the operating system and the application programs .The operating system-Windows 98 (English Version) or-Windows NT Workstation Ver4.0 (English Version)-Windows 2000 (English Version)The application programs-PNMT softwareOther applications:-Internet Explorer 5.0 or higher-Acrobat Reader (to read Help File with PDF)- 4 -ROI-S04451This chapter explains the menu structure and procedures for operating of the PNMT. Theexplanation uses typical PNMT screens to illustrate the hierarchy of menu.2.1 The PNMT ScreenThe PNMT window is comprised of the following main parts (Refer to figure 1).For detailed descriptions, refer to the Users Manual for the Windows NT operating system.Title barThe title bar of the window is used to indicate the title of the window.oCommon Menu barThe common menu bar of the window presents the System and Help options, illustrates the commands that can be executed from the various options. The Help function also can display the html version of this operation manual.oNE-specific Menu barThis menu is a list of tasks that can be performed to the specific network element(NE) displayed in the PNMT. Configuration, Event Log, and Link PerformanceMonitor functions can be executed in the NE-specific Menu bar.oBlock DiagramThe block diagram illustrates the equipments of the Pasolink Radio system. Its main purpose in the window is to display the current summary alarm state of theequipment. You can click on a specific block to display the status of equipment in the data window.ooData windowThis window displays in detail the status and alarm items of a specific equipment of the NE. You can select the tab or the block of the specific equipment you want to monitor in the data window.TabsTo view the status and alarms in the Pasolink radio, click on the tab at the bottom of the Data window.oCommand ButtonThe command button is used to enter the data selected on the pop-up window into the computer.ooSelectable FieldThe selectable field is a standard Windows input field where the user can scroll down on a list of values available for that option.Login UserThis indicates the current user that logged-in in the PNMT.o- 5 -2 System Operation & MaintenanceROI-S04451Title BarNE-Specific Menu BarBlock DiagramCommonMenu BarCommonTool BarDataWindowTabsLogin UserSelectable FieldCommand ButtonFig. 1: Common Parts of a Window- 6 -ROI-S044512.2Launching the PNMT application.To start PNMT:1.Power ON the system.NOTEConnect the RS-232C cable 30seconds after IDU'spower is ON make sure that the RS-232C cable is connected between Com 1 of the PNMT PC and thePNMT Port of the IDU.2.Login to Windows 2000/NT/98 Workstation.

Consequently, 11 parallel alarms can bedefined. Relays RL01, RL02 and RL03 have fixed alarms. Maintenance, PS ALM andCPU Alarm are outputted on RL01, RL02 and RL03 respectively.RL04 to RL11 are user-definable relays. If the HK-OUTs are enabled, RL08 to RL11 areallocated for Housekeeping (HK) alarms.The PNMT allows the user to configure the relays in a table format. The columnsindicate the relays (RL01 to RL11) and the rows indicate the parallel alarms available in the Pasolink+ IDU. The following indicators are used in the table: Out indicates that the alarm - in the corresponding row, is issued on thecorresponding relay. HK Indicates that the corresponding relay is used for House Keeping.Mask Indicates that no alarm is issued in the corresponding relay when the maintenance mode is activated.

The Radio section is available 1+1systems only and is used for switchover function. The figure below illustrates these sectionsThe MUX and DMR section BER is measured in terms of Signal Degrade and E-BER.Signal Degrade is triggered when the BER is worse than the preset threshold (1E-6,1E-7, etc.). Excessive BER (E-BER) occurs when the BER is worse than the preset threshold (1E-3, 1E-4, or 1E-5).The radio section, on the other hand, monitors the BER for switchover purposes. Whenthe BER becomes worst than the preset value (3E-6,3E-7, etc) of the Low BER (RX Switch) the RX is switched to the other system in a 1+1 configuration. In a similarmanner, when the BER becomes worse than the preset value (3E-4,3E-5,3E-6) forHigh BER, the switched to the other system.The preset value mentioned above is called the BER Threshold. The BER thresholdcan be set in 6 points: (1) Signal Degrade (MUX), (2) E-BER (MUX), (3) Signal Degrade (DMR), (4) E-BER (MUX), (5) Low BER, and (6) High BER. Low BER and High BER, however, are only available in 1+1 systems.The MUX and DMR are classified with B1, B2 and B3 section respectively. There is E- BER only for B32.20.8.1B1 Signal Degrade (MUX)To set the threshold for signal degrade:1.Click on the [B1 Signal Degrade (MUX)] button in the Provisioning window.2.Select the preset BER value that will trigger the signal degrade.
