1. Getting Started

1.1 Introduction The PNMT is a Pasolink Network Management Terminal developed by NEC for management of 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 maintenance tool 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 and controls 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.

2 System Operation & Maintenance

This chapter explains the menu structure and procedures for operating of the PNMT. The explanation 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). For detailed descriptions, refer to the Users Manual for the Windows NT operating system.

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

o Common Menu bar The 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.

o NE-specific Menu bar This 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 Performance Monitor functions can be executed in the NE-specific Menu bar.

o Block Diagram The 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 the equipment. You can click on a specific block to display the status of equipment in the data window.

o Data window This 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.

o Tabs To view the status and alarms in the Pasolink radio, click on the tab at the bottom of the Data window.

o Command Button The command button is used to enter the data selected on the pop-up window into the computer.

o Selectable Field The selectable field is a standard Windows input field where the user can scroll down on a list of values available for that option.

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

2.15.4 Relay Configuration

There are 11 relays in the Pasolink+ IDU. Consequently, 11 parallel alarms can be defined. Relays RL01, RL02 and RL03 have fixed alarms. Maintenance, PS ALM and CPU 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 are allocated for Housekeeping (HK) alarms.

The PNMT allows the user to configure the relays in a table format. The columns indicate 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 the

corresponding 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. Blank button not related to the corresponding alarm.

The BER in the Pasolink+ system is monitored in 3 sections - (1) the MUX section,

(2) the DMR section and the (3) Radio section. The Radio section is available 1+1 systems only and is used for switchover function. The figure below illustrates these sections

The 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. When the 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 similar manner, when the BER becomes worse than the preset value (3E-4,3E-5,3E-6) for High BER, the switched to the other system.

The preset value mentioned above is called the BER Threshold. The BER threshold can 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 B3

2.20.10.1 B1 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. The factory setting is 1E-6.

3. Click on [Execute] button to apply the new threshold.


2.20.10.2 B1 E-BER (MUX)

To set the E-BER Threshold for the MUX section:

1. Click on the [B1 E-BER (MUX)] button in the Provisioning window.

2. Select the preset value wherein the E-BER will be triggered.

2.21 Link Performance Monitor The following performance items can be monitored according to G.826 recommendation:

Out of Frame Second (OFS) - the total number of seconds the out of frame condition is generated in 15 minute-blocks.(OFS is applied to the RST only)

Errored Second (ES) the cumulative time in which more than one B1 error pulse per second was detected (ES is not applied to the MSA)

Severely Errored Second (SES) the cumulative time in which the BER of one-second period exceeded 10E-3. (SES is not applied to the MSA)

Unavailable Second (UAS) the cumulative time in which the unit remained inoperative (UAS is not applied to the MSA)

Background Block Error (BBE) - the sum of the B1 background block error

PJE+ (is applied to the MSA only)
