4 – 7390LT software overview 4.1 – General information The purpose of this chapter is to present the different screens of the 7390LT software supplied with the Base Station. The following chapters will make reference to this presentation each time the user needs to access the software for a particular action (commissioning, maintenance or evolution of the configuration). The same screen may apply for several types of action. 4.1.
4.1.2.2 – Entry fields The grayed out fields are for consultation only: their content cannot be modified. The fields on a white background can be modified: left-click to make the cursor appear inside the field, then enter the character string required. According to the same principle, the buttons, icons and items in the pull-down menus become grayed out when they are inactive. 4.1.2.
4.1.2.6 – Title, menu, button and status message bars The various information and functionalities of the 7390LT are accessible in several forms of MMI: Title bars (at the top of the main window): for information only; this is the title of the window. Menu bar (below the title bar): each menu contains items. To access, open the pull-down menu by left-clicking on the title, then click on the desired item (for execution it must be active, cf. § 4.1.2.2 – Entry fields).
4.1.4 – Printing To print all the elements of the list To print all the elements selected in the list To print the elements non selected in the Color printing Black and white printing Direction of the page: landscape (horizontal) Direction of the page: portrait (vertical) Note: to know how to select lines in lists, see § 4.1.2.5 – Selecting lines on a list.
4.2 – Running and quitting the software 4.2.1 – Installation of the 7390 LT software The 7390 LT is either loaded on the PC which came with the BS, or comes on an installation medium (e.g., CD-ROM). If you need to install the 7390 LT software, refer to the Appendix 2 – Installation of 7390LT software; otherwise, go directly to the next paragraph to run the already installed software. ON THE ETHERNET PORT IT IS RECOMMENDED TO CONFIGURE ONLY ONE IP ADDRESS 4.2.
On the screen displayed, only one icon is active: the choice of language and the NE connection icon: ...click on the icon to access the NE connection (cf. comments in § 4.3.1 – NE Connection) 4.2.
4.3 – Connection and Disconnection 4.3.1 – NE Connection The NE connection process consists partly in the NE "Agent" identifying the "Manager" and partly in the retrieval of data for the NE assembly on the 7390 LT software by manual request: this involves the updating of site information. ONLY ONE LT SESSION IS OPERATIONAL ON ONE NE.
By default, the update is done via FTP. The next screens will be displayed: Note: In order to start the FTP process, there must not be any other FTP service or application running in the PC. Windows NT includes a FTP service that is, by default, desactivated; if it were activated, the operator must stop it from the Services window through the Control Panel. If there were any problem with the FTP process, the craft.ini file must be opened. Change the UploadThruFTP value, it must be: UploadThruFTP=No.
Note: While updating, if the database versions at the Manager and Agent sides are not identical, the animation stops and an error message is displayed to notify it. (cf. corrective actions in appendix A.6.1 – Error messages for 9900LT software). Once the update is completed, two new windows are displayed: – one screen providing a global view of the base station (cf. § 4.5 – Base Station Supervision); – and one screen summarising the current alarms (cf. § 4.10.1 – Alarms).
4.3.2 – Disconnecting the NE assembly The NE disconnection process consists in closing the current session relating to a given NE in order to connect to another NE of the system. To access the NE disconnection function, open the Management pull-down menu then select the item: Disconnect NE.
4.4 – Supervision Principles The 7390 LT can be used for supervising the whole A7390 Network Element (NE) system. The NE comprises of: – a Base Station (7390BS) which mainly includes a Radio unit (X-Pol RBS) and a MODEM rack (DBS), – one or more Terminal Stations (7390TS) which mainly include a Radio unit (X-Pol RT) and a User connection unit (NT). Nevertheless the 7390 LT software does not manage X-Pol RT units.
4.5 – Base Station Supervision When the LT is started up for the first time, the Manager has to define the type of polarization used, in this «Cross-polarization» type must be selected Click to choose Cross-Polarization type AFTER CLICKING ON THE «APPLY» BUTTON, A WARNING WINDOW WILL APPEAR SINCE THIS PROGRESS IS IRREVERSIBLE, EXCEPT THROUGH AN ANT RAM-REINITIALIZATION. ONCE ACCEPTED, THE 7390LT STARTS TO RECEIVE EVENTS FROM THE SYSTEM Synchronization parameters: cf.§.4.5.4 – BS Supervision: cf.§ 4.5.
