1 INTRODUCTION

The WALKair V3.1 Commissioning Guide provides instructions for serviceand installation technicians, in order to facilitate the proper initialization andconfiguration of the WALKair V3.1 Base Station and Terminal Station.

Detailed instruction relating to the operation of the WALKair V3.1 system isavailable in the WALKair V3.1 Operation and Maintenance Manual, and theWALKnet User Manual.

1.1 Safety Precautions

High voltages are present at specific points in this electrical equipment. Someof the parts can also have high operating temperatures. Non-observance ofthese conditions and safety instructions can result in personal injury or inproperty damage.

The WALKair V3.1 system complies with the standard EN 60950. Allconnected equipment must comply with the applicable safety standards.

Equipment complies with the following EMC and safety standards:

EN 50081-1

EN 55022 IEC 100-4-as 2, 3, 4, 5, 6, 8, 11

ETSI 300339

2 OVERVIEW OF THE SYSTEM COMMISSIONING

PROCESS

This section provides a general overview of the commissioning process, andexplains system characteristics on first-time commissioning.

The commissioning procedure is comprised of three stages:

Commissioning of the BS.

Commissioning of the TS

Post Commissioning Acceptance Protocol Testing.

The BS must be first in the commissioning procedure. This is to enableverification of each TS after commissioning. Failure to conform to theprocedure may result in undue travel, between the BS and TSs, for theinstallation personnel. Where it is determined that a TS is not serviceableafter commissioning, the installer will be able to take immediate correctiveactions. Figure 2-1 illustrates a block diagram of the Commissioning process.

2.1 BS-BU Commissioning

The BS Commissioning process is performed by the Commissioner via directconnection to the BU for the following:

Connecting the LCI to the BS-BU

Defining the Network Parameters

All other BS Commissioning procedures are preformed by the Commissioneror Network Manager via WALKnet for the following:

Radio Parameters

Administrative Parameters

Telecom Parameters

Defining Services

These parameters can be defined in two ways; by direct connection to the BUor by a Network connection to the NMS. Figure 2-2 illustrates a typical directconnection to the BU, and Figure 2-3 illustrates typical Network connection tothe NMS.

See WALKnet section 4.2.3 Frequency Planningand section 4.3.5 AntennaConfigurationfor the following:

Setting the Radio Parameters

Set the RFU Head Type

Set the IF Cable Type and lengthThe IF cable connects with the indoor and the outdoor units. Thesystem requires the IF cable attenuation data in order to adjust theoutput signal. The cable attenuation can either be entered manually,or computed by the system based on the specified IF length and type

Set the IF Cable Type of cables other than the LMR400

If Other Cable type was entered, the Gain table for the IF cablemust be entered as described by vendor specifications

Set the Gain tableThe IF cable attenuation data can be computed by the system ormanually entered by the user. Prior to entering this option, ensurethat the cable gain (attenuation) has been measured.

Setting the Modem Working Point for nominal Tx, Rx and default values.Typically, the default settings are used, however it is possible to configurethe Modem Working point in order to optimize modem performance.

When setting the Modem Working Point, select either the default values or

enter the Site Planning values for Tx and Rx.

You can configure the Telecom ports for Registered TSs thatare not connected or installed. Once a connection is established between theBS-BU and the TS-BU, the TS-BU receives these parameters.

When updating the BS Telecom Configuration parameters, all ports areupdated and set to the Disable State. The displayed parameters for theTelecom Interface will vary depending on the type of Telecom card installedon each port.

In the case of a mismatch between the configured and detected port types,

WALKair transmits a Trap.

4 LEASED LINE SERVICE MANAGEMENT

The Leased Line Services dialog enables definition of Leased Line Servicesfrom the Telecom port of the specified BS-BU to the Telecom port ofTerminals in the system. You can configure these services for uninstalledand/or disconnected Terminal Stations. Once a connection is establishedbetween the BS-BU and the TS-BU, the TS-BU receives these parameters.

WALKair supports Leased Line Services defined over both E1 Telecom cardsand V.35/X.21 Telecom cards participation in this service (see Figure 4-1).Table 4-1describes the dialog elements available from the Leased LineServices dialog.

5 TS COMMISSIONING

This chapter describes the commissioning process for the WALKair V3.1Terminal Station via the LCI. The TS Commissioning process is performed bythe Commissioner via direct connection to the TS-BU using the LCI for thefollowing:

1. Connecting the Local Craft Terminal to the TS/BU

2. Setting the Radio Link Parameters

Setting the RFU Head Type

Setting the IF cable length and type (IF cable gain)

3. Setting the Administrative Parameters

NOTE

Repeat Steps 2 3 for each installed TS/BU.

5.1 Step 1:Connecting the LCI Terminal to the TS/BU

Connection to a TS/BU is made with an RS-232 Communications Cable.

The RJ-45 connector is attached to the receptacle marked LCI. The D-Typeconnector is connected to the communications port of the Local Craft PC(see Figure 5-1).

5.1.1 Global Navigation Key Symbol Commands

The LCI software provides several global key symbol commands in order tofacilitate navigation of the Menu Structure as shown in Table 3-5.


TABLE 5-1: GLOBAL NAVIGATION KEY SYMBOL COMMANDS

SYMBOLS FUNCTION

* Press * to access the Main (root) menu in the software.From the main menu, you access all other LCI functions.

^ Press ^ to access the previous menu in the LCI screenin the LCI hierarchy.

= Press = anytime to refresh the LCI monitor screen. Thiserases all information that was on the screen and re-displays thecurrent menu at the top of the screen.

% Press % to toggle the ON/OFF display mode of errormessages should they occur.

+ Press + to advance the print level. The change isdisplayed on the LCI monitor.

- Press - to reduce the print level. The change isdisplayed on the LCI monitor.

The LCI reports system alarms and events by displaying messages on theterminal monitor. The type of messages that are printed depends on the setprint level.

Table 5-2 lists the prints levels in descending order. Note that each print levelincludes the lower level messages.

5.3.3 TS Scanning

The TS starts scanning the RFU for available frequencies, searching for adownlink transmission (seeks a signal above a certain threshold). When the

received signal strength is above a certain threshold, the TS will attemptsynchronization.

Upon success, the TS waits for the customer ID search message, with theCustomer ID in the downlink:

If the Customer ID does not appear in the downlink, the TS continuesscanning.

If the Customer ID appears in the downlink and matches the ID in the TS-BU,the scanning stops and the TS waits for EOC allocation.
