1 Getting Started

1.1 Introduction

The PNMT is a PASOLINK Network Management Terminal developed by NEC formanagement of NECs PASOLINK radio transmission network. The PNMT is a scaleddown version of PASOLINK Network Management System (PNMS) that is designed as amaintenance tool for field engineers to locally and remotely monitor alarms, control points,generate reports, and archive data, all within a familiar graphical user interface, and all inreal time. The PNMT is a Mobile laptop computer fitted with NEC PNMT softwarepackage that interfaces and controls NEC series short haul radio equipment.

This software package remote monitors and controls the status and configuration of anentire network with associated equipment as well as the performance of the actualmicrowave links.

1.3 PNMT Communication Interfaces

1.3.1 Communications

Communications between the PNMT and the radio network equipment can be

via the LA PORT of the PASOLINK equipment, via the DSC to a remote PM node in the network.

a) LA Port Interface

On PASOLINK equipment, the LA Port is mounted on the front of the equipment.

The LA Port consists of a DB15 connector and connects to PM installed in IDU via a serialcable to the relevant communications port of the PNMT Computer.

The LA Port has the following properties:

Port Configuration: RS-232

Connector type: Subminiature DB15 (female) Bit per second rate: 1200/2400/4800/9600/19200 (default 19200)

Stop bits: 1

Data bit length: 8

Parity: no parity.

The following table is given cabling pin assignment of the connection between LA Portand PNMT PC.

2 System Operation & Maintenance

This 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 Screen

The PNMT window is comprised of the following main parts (Refer to Figure 1).

o Title barThe title bar of the window is used to indicate the title of the window.

o Common Menu barThe common menu bar of the window presents the System, Refresh andHelpoptions, illustrates the commands that can be executed from the various options.The Help function also can display the PDF version of this operation manual.

o NE-specific Menu barThis menu is a list of tasks that can be performed to the specific network element(NE) displayed in PNMT. Configuration, Event Log, and Link Performance Monitorfunctions can be executed in NE-specific Menu bar.

o Block DiagramThe block diagram illustrates the equipments of the PASOLINK radio system. Itsmain purpose in window is to display the current summary alarm state of theequipment. You can click a specific block to display the status of equipment in thedata window.

o Data window

This window displays in detail the status and alarm items of a specific equipment ofthe NE. You can select the tab or the block of the specific equipment you want tomonitor in the data window.

o TabsTo view the status and alarms in the PASOLINK radio, click tab at the bottom of theData window.

o Command ButtonThe command button is used to enter the data selected on pop-up window into thecomputer.

o Selectable FieldThe selectable field is a standard Windows input field where the user can scrolldown on a list of values available for that option.

o Login UserThis indicates the current user that logged-in in the PNMT.
