OMT for RBS

OMT Main Window

In the OMT Main window is a View window. All information is displayed in a separate

window. Several windows can be open at any time. In this example only one, containing

information about the IDB, is shown. There is a status bar at the bottom of the Main

window. The Status bar shows the current OMT State

and the selected object or a help text for the highlighted menu option.

There is a toolbar at the top of the Main window. The toolbar shows the most common operations.

These operations can be executed by clicking on an icon on the toolbar or by selecting the operation in the menu.

Different Main Menus

File: The File menu contains IDB-related

commands, for example, Read IDB and Install IDB.

These commands can also be found under the Operation menu when the IDB object is selected.

Under the File menu is also the Exit command which closes the OMT application.

Connection: The Connection menu contains

the commands that handle the connection between the OMT and the RBS.View:

The View menu makes it possible to select different views: System Overview, Cabinet View, Hardware View etc.,

Object: The different objects for the chosen view can

be found under the Object menu. For example, RUs, Alarm Inlets. Operation:

The Operation menu contains the different operations that are available for the chosen object.

Every object has operations that can be executed.

The operations are not the same for all objects so the command options in the Operation menu change depending on the chosen object.

Window: Commands that are used to arrange windows

and icons are found under the Window menu.Help:

The Help menu offers commands that display help pages for both the OMT application and the help tool.

OMT States

The OMT executes in one of five different states which are: Init, Local IDB, Connected (No IDB), Connected (Local IDB) and Connected.

The current OMT State is displayed on the Status bar.

Some operations cannot be performed in all states.

Menu items representing operations not available in the current state are disabled and displayed in light grey text.

Init: The OMT is in the Init state when it is started. In this state, the OMT is not connected to the

RBS and does not operate on any IDB. The only view available in this state is the

System Overview.Local IDB: In this state, the OMT is not connected to the

RBS, but is operating on a local copy of the IDB in the OMT.

Connected (No IDB): Here the OMT is connected to the RBS

but has no access to any IDB copy. The only view available in this state is

the System Overview. The Connected (No IDB) state should be

seen as a transitional state, because this state does not offer any new operations or functions compared to the Local IDB or Connected state.

Connected (Local IDB): Now the OMT is connected to the RBS and

operates on a local IDB copy. The Connected (Local IDB) state should, like

the Connected (No IDB) state, be seen as a transitional state.

Connected: In this state, the OMT is connected to the RBS

and operates on an IDB copied to or from the RBS.

The IDB has been read from the RBS to the OMT.

The OMT can be executed in different states.

Depending on the type of command executed the OMT may move from one state to the other.

For example, if the OMT operates in state Init and the Connect command is executed, the OMT State changes to the Connected (No IDB) state.

View

A view displays the RBS 2000 system graphically.

There are four types of views: System Overview, Cabinet View,

Hardware View and MO View.To select a view:

1. Select View | <a view>.

System Overview

The System Overview window shows the BSC, the PCM link, the Alarm Inlets, the RBS, the OMT and the IDB, that is, an overview of the whole system.

The System Overview is displayed when the program is first started.

Cabinet Overview

The Cabinet View window shows the hardware items in the RBS, that is, the cabinet appearance.

All objects that can be selected when this view is active are not visible in the normal view.

BDM stands for Battery Distribution module. It is similar to IDM.

Hardware View

The Hardware View window shows the RBS’s schematic structure.

There are hidden objects such as Sensors and Cables.

These objects can be selected through the Main menu Object.

MO View

Managed Object (MO) is the name of a generalised object.

An operation defined for an MO is actually defined for the TRX.

The Managed Objects have also internal state that you can manipulate by commands from Base Station Controller (BSC).

These states are Reset, Start, Disable and Enable.

The Managed Objects CF, TF, DP, CON and IS corresponds to the hardware unit DXU in the BTS.

The Managed Objects TRX, TX, RX and TS corresponds to the hardware unit TRU in the BTS.

Using OMTStart the OMT as follows:1. Open the Start menu.2. Select Programs.3. Select the OMT menu.4. Select the installed OMT version from the menu.

The Exit Command The Exit command closes the OMT application. The command performs the following actions

before closing the program: close all open windows and disconnect the OMT from the RBS.

Connect: A connection between the OMT and the

RBS must be established before the OMT can use the IDB in the RBS or monitor information.

The connection is established with the Connect command.

Connect the OMT to the RBS as follows:1. Select Connection | Connect.

There are different operations like Read IDB, Open IDB, Install IDB each of which performs the specified task.

“Read IDB” command transfers an IDB copy from the RBS to the OMT.

Execute the Install IDB command to install the IDB that the OMT is operating on into the RBS.

The IDB in the RBS is replaced by the IDB that the OMT is operating on.

The DXU must be in Local Mode to be able to accept a new IDB.

Read IDB

1. Choose connect from the connection menu.

The line between OMT and RBS 2000 is connected.

2. Choose Read IDB from the file menu.
