7390 LT software overview
4.1 General information
The purpose of this chapter is to present the different screens of the 7390 LT 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.
4.1.1
Functionalities
The 7390 LT software enables:
– supervision of both the system assembly as a whole (the NE (Network Element)), and of its subassemblies (BS, NT);
– configuration of the sub-assemblies (DBS, RBS, etc.) (used when Commissioning, Chapter 5
Commissioning the Base Station (7390BS));
– setting up services (E1 leased lines, T1 and X21, ISDN, IP cross-connection including VoIP, circuit
emulation), (used when Commissioning, Chapter 6 Operation and maintenance);
– downloading, NE configuration back-up and restoration (used in Maintenance, Chapter 6 Operation and maintenance);
– display of the system redundancy state;
– management of external points.
– radio performances.
Note: the 7390 LT software exchanges no information with the radio part of the terminal station (7390
RT). These generate no alarms, and therefore require no other configuration apart from the installation configuration.
4.1.2
Principles of the Man-Machine Interface (MMI) of the 7390 LT
The user of the 7390 LT software is expected to be familiar with the operation of software in the
Windows NTMT environment. There follows a description of some of the basic principles of the
Windows NTMT MMI along with others, more specific to the 7390 LT.
4.1.2.1
Opening, closing and resizing a window
Here is a reminder of how the boxes at the top right of an active window are used:
Click on...
To......
...minimize the active window to place the application on the taskbar.
Click on the taskbar icon to restore the window.
...maximize the window to full-screen size.
...restore a window which was in full-screen size to its original size.

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.
4.1.2.3
Confirmation, closing a window, canceling an entry
In the lower part of the windows there may be buttons (which may or may not be active; cf. § 4.1.2.2
Entry fields), the principle of which is as follows:
Click on...
To......
...confirm the data entry, while keeping the window open.
...close the active window, thereby cancelling any unconfirmed data entries.
...cancel the data entry, while keeping the window open.
4.1.2.4
Sorting and searching in a list
Some screens contain lists which may contain many lines; a sort and/or search tool is therefore available
via the MMI, in order to facilitate data management:
4.1.2.5
Selecting lines on a list
To select a line, click on it and it is highlighted in blue.
To select quickly a zone, click on the first line then select and hold down the 'Shift' key, then click on the
last line of the desired zone. The zone becomes highlighted in blue.
To select several non consecutive lines, hold down the 'Ctrl' key then select line by line the desired
elements.

Entry fields).
Button bar (below the title bar): certain menu functionalities are also
directly accessible by clicking on the buttons displayed at the top of the
window.
Message bar (at the bottom of the active window): messages linked to
current events are displayed on the fly in certain windows
Status bar (at the bottom of the 7390 LT main window), divided into 2
areas:
– on the left: global user's messages (states of progress, error messages, etc.)
– on the right: Local access: information about write access: cf. §
4.4.2 Local access requests
– Number of NTs: displays the number of NTs declared in the NE.
– Most critical alarm: displays the color of the most critical alarm (see
alarm color codes, § 4.10.1.2 Alarms color code).
4.1.2.7
Dynamic keys
Each time the cursor will stay a few seconds on a button (and on specific
field), a textual key on a yellow background defining this button (or field)
is displayed.
4.1.3
Rearrangement of active windows
During the use of the 7390 LT software, several windows may be active simultaneously. The MMI allows
you to rearrange them to optimize their visibility, in classic Windows fashion.

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. FOR EXAMPLE,
A LOCAL LT CONNECTION AND A REMOTE LT CONNECTION AT THE
SAME TIME ON THE SAME BS IS NOT POSSIBLE.
There are two possible ways of accessing the NE Connection:
– click on the first button (provided that it is active; cf. § 4.1.2.2 Entry fields)
of the main menu button bar,
or else,
– open the Management pull-down menu and select the first item:
NE Connection.
The following screen is displayed:
IP Address of the NE to be connected: click in a byte field
value (local IP default address value must be: 192.168.99.1
Connection type: with
data upload (default
selection)
Subject of
supervision: NE
system or BS
Network Type: there
are two types of
network: local (LAN)
or remote (WAN):
check the button for
the type of network
corresponding to the
system configuration
Click here to run the data update procedure
In case several interface boards are installed in the PC, the window offers you a choice of boards.

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. Throughout the update, an animated display
indicates to the user that data transmission is underway, with on-screen indication of the progress of the
processed files. In this case, the next screen would be displayed:

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
Appendix 6 – Error messages and corrective actions).
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);

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 (RBS) and a MODEM rack (DBS),
– one or more Terminal Stations (7390TS) which mainly include a Radio unit (RT) and a User connection unit (NT). Nevertheless the 7390 LT software does not manage RT units.
The display allows system control; alarms are activated in particular to signify any intervention.
The supervision items themselves are,by definition, grayed out and therefore unmodifiable, whereas
those reserved for configuration can be configured by the user: they will be used in the following
chapters concerning commissioning (Chapter 5 Commissioning the Base Station (7390BS)),
maintenance (Chapter 6 Operation and maintenance) and configuration evolution (Chapter 7 Changes
of configuration). For the modifications to be taken into account, writing should be enabled: see §
4.4.2 Local access requests.
4.4.1
Data retrieval
According to the same principle as for starting up the 7390 LT (automatic data retrieval following
connection), this update can be carried either for whole NE, or for each equipment: BS or NT.
To reach the Data retrieval function, two ways are possible:
– open the Database pull-down menu and choose the first item: NE MIB
Upload,
– or click on one of the buttons in the screen of the equipment in question:
Click on......
To......
...activate the data recovery function for the NE, BS, and NT respectively.
Note: These operations may take quite a long time (in particular for the NE) since they depend on the
connection between NE and manager and on the round trip delay and the NE composition.
4.4.2
Local access requests
The general status bar (cf. § 4.1.2.6 Title, menu, button and status message bars) displays in its central
part the messages concerning write access rights on the NT configuration: "Local Access : Denied /
granted". Where there are different system managers, these access rights are allocated by the OS
manager, write access is authorized for the 7390 LT (local access set to granted) when no OS manager
is connected to the NE (local access set to granted) when no OS manager is connected to the NE.
4.4.3
Administrative statuses
Locking the administrative status of sub-assemblies allows the maintenance operator to disable the
sub-assembly manifesting an anomaly without disturbing the system.
Unlocking sub-assembly administrative status frees service use for the end user.
Operator is not able to modify the administrative state assembly. He can only change the ports and
cross-connections.

Base Station Supervision
To Start or Stop the supervision of the Base Station:
Click on the icon to start the supervision of the Base Station.
Click on the icon to stop the supervision of the Base Station.
BS supervised means that the agent sends to the manager all the events related to the Base station.
When the BS is supervised the «Start BS Supervision» button is disabled.
When the BS is not supervised the «Stop BS Supervision» button is disabled and a red message in
the status bar indicates to the operator that the equipment is not supervised. Besides, not supervised
status implies that no action can be performed on the BS from the LT manager. Therefore, if the BS is
not supervised then no alarm is sent to the BS element. So, not supervision state implies alarms not
allowed (the «Allow BS Alarms» button is disabled).
To Allow or Inhibit the alarms of the Base Station:
Click on this icon to allow receiving the alarms of the Base Station.
Click on this icon to inhibit receiving the alarms of the Base Station.
BS Alarms allowed means that all the alarms present in the BS equipment will be reported to the LT
manager.
When the BS alarms are allowed, the «Allow BS Alarms» button is disabled.
When the BS alarms are inhibited, the «Inhibit BS alarms» button is disabled. Moreover, all the status
led boards in the BS appears in grey colour to indicate that it is unknown if the boards have or do not
have alarms present.

Clock synchronization parameters
To access the synchronization parameters, click on the button shown here (in the button
bar of the BS Details screen).
This involves defining the setup rules for the synchronization sources used.
There is one default synchronization source (internal oscillator) and six configurable sources: ATM,
external clock and the four TNT boards. The TNT boards have 16 ports and 4 can be used as
synchronization ports: these are ports 1, 5, 9 and 13.
– Priority principle:
•
the order of priority numbers take precedence, followed by the channel numbers, in increasing order of appearance.
•
an order number must be single (one specific number per sub-assembly).
•
Order number one is for the highest level of priority.
Note: Two sources cannot be assigned the same order of priority (the «Apply» button is not available).
Note: In the screen shown in the above example, the warning message under TNT card N°2 is displayed because the type of input for the TNT 2 card has been set to ATM (see § 4.5.3.2 TNT
board screen), this board is thus in Circuit Emulation mode.

redundancy" mode. That means for one active entity, there is one stand-by entity and when the active
entity has failed, the switch over to the stand-by entity provokes a temporary service cut.
Redundancy applies to the management part (ANT board) and to the radio part (radio links) of the
system.

Comments on radio link 2 as shown in the previous example:
Radio link 2 initially consists of the AMD 2 (slot 8), IBS 2 (slot 18) and RBS 2 triplet.
The redundancy capability of radio link 2 comes with the installation of the AMD 6 (slot 12), IBS 6 (slot
22) and RBS 6 triplet.
The BS Details screen (§ 4.5 Base Station Supervision) allows the boards inserted in the cabinet and
associated RBSs to be displayed, and also their role in redundancy. The operating entities may also be
displayed with the operation symbol (double-arrow).
In the example, the AMD 2 card has been removed; it is thus reported as a critical alarm (red) (see §
4.10.1 Alarms). Triplet 1 is no longer operational: consequently, switch-over was to triplet 2, this is
confirmed by the presence of the operation symbol on AMD 6 and IBS 6 cards and on RBS 6.
This information is grouped on the Redundancy screen (§ 4.5.8.2 Access to redundancy state display):
– operational state of the AMD2 card reported "disabled", (card withdrawn)
– availability of triplet 2= "Not installed",
– availability of triplet 6= "On line" with operation symbol present.
Conclusion: radio link 2 is available and operating via triplet 6.

NT Supervision
To Start or Stop the supervision of the NT:
Click on this icon to start the supervision of the NT.
Click on this icon to stop the supervision of the NT.
NT supervised means that the system sends to the manager all the events corresponding to that NT.
A given NT can be supervised only if the BS is supervised.
When a NT is supervised, the «Start NT Supervision» button is disabled.
When the NT is not supervised the «Stop NT Supervision» button is disabled. Then, no action can be
applied over it, so all the «Apply» buttons are disabled. Therefore it implies that the alarms on this NT
are not allowed (the «Allow NT Alarms» button is disabled).
To Allow or Inhibit the alarms of the NT:
Click on this icon to allow receiving the alarms of the NT.
Click on this icon to inhibit receiving the alarms of the NT.
NT Alarms allowed means that all the alarms present in the NT equipment will be reported to the LT
manager.
Allowing or inhibiting alarms on NTs have to be done one by one. It is not possible to allow or inhibit
alarms in all the NTs by one action.
When the NT alarms are allowed, the «Allow NT Alarms» button is disabled.
When the NT alarms are inhibited, the «Inhibit NT Alarms» button is disabled. When the alarms are
inhibited on a given NT, the NT appears grey in the NT list screen to indicate that it is unknown if the NT
has or does not have any alarm present.

4.7.3
On-demand Service management
4.7.3.1
Introduction
Radio resources management consists of distributing system resources, for each upstream and
downstream channel of each radio link, according to customer services to be created.
Customer services are available according to two types of radio traffic: dynamic (dynamic IP) and static
(leased lines, static IP).
The bit rate available for each radio channel is given by the bandwidth defined in the Radio
Configuration screen (see § 4.7.1 Radio configuration).
Radio resources management is carried out according to two operating principles (that can be jointly
implemented): system self-management (default configuration) and pre-configuration (carried out by
the operator).
STATIC SERVICES CONFIGURATION MAY CAUSE DYNAMIC IP
SERVICES TO BE SHUT DOWN
– System self-management:
In this case, the system automatically manages the radio part according to the following principles:;
• by default, overbooking limit is 1. That means no overbooking is allowed.
•
CAG = Guaranteed MCR.
•
RRM Devices Enabled = Policing.
Note: Circuit emulation always requires a leased line. Radio resources are implicitly dedicated to circuit
emulation via the leased line.
4.7.3.2
Access to the radio pre-configuration
To access on-demand services management and proceed with radio preconfiguration, click on the button shown here (in the button bar of the BS Details
screen).

Policing: is a buffer management function that implements intelligent discard mechanisms to prevent
buffer overflows.
Overbooking:
– limit = 0 means that overbooking has no sense because in this upstream dynamic traffic is not allowed,
– limit = 1 means no overbooking is allowed,
– limit > 1 means it is possible to use more bandwidth than the physical one.

– Upstream channels
Call Admission Control Strategy:
– Guaranteed MCR, allows the CAC to deny connection to an RRM port if the current sum of the
connected RRM ports does not allow to accept the new RRM port without exceeding the dynamic
resources.
Degraded MCR allowed:
– allows the CAC to accept every connection request. In this case, congestion event may happen
and the RRM scheduler will need to degrade the MCR contract parameter of each connected
RRM port, up to its "maximum degraded MCR".
4.7.4
Bandwidth allocation
The 7390LT offers the capacity to display radio resources reserved for traffic and therefore potentially
available to create customer services.
THE RADIO RESOURCES DISPLAYED CORRESPOND TO BANDWIDTH
ALLOCATION AND NOT TO THE CURRENT TRAFFIC ON
THE SERVICES CREATED.
To view reserved radio resources, click on the button shown here (BS Details screen
toolbar).
Nota : The system always runs in self management mode, but pre-configuration is possible to avoid
shutdown during static service creation; thus the system automatically returns to self management mode if the capabilities are exceeded

Click on these tabs to display the radio resources of the other channels
Meaning of the colors used to show the different parts of the bandwidth:
The blue zone represents the bit rate allocated to leased lines (LL) type services.
The yellow zone represents the bit rate allocated to static IP (IPstat) type services.
The light grey zone represents the proportion of bit rate still available to create new static services
(FreeS) without disturbing the dynamic zone.
The dark grey zone represents the proportion of bit rate still available to create new dynamic services
(FreeD).
The green zone represents the bit rate allocated to the dynamic IP (IPdyn) type services, as the
physical limit of the system reserved to the dynamic services has not been reached (OF<1).
Once the bandwidth is filled, (maximum bit rate authorized by the system’s physical limits), the zone is
displayed in orange to warn the operator of the risk of dynamic service unavailability.
When the bit rate allocated to the dynamic services exceeds the booking factor limit (OFL), the zone
changes to red.
IF THE ZONE IS ORANGE, CHECK THAT SIZE OF THE REMAINING DYNAMIC
ZONE IS GREATER THAN THE LARGER DYNAMIC CROSS-CONNECTION
IF IT’S NOT THE CASE THIS CONNECTION WILL BE UNAVAILABLE.
The whole bandwidth is represented on a scale from 0 to 100%.
It is divided into three zones: the static LL zone, the static IP zone and the dynamic IP zone.
The static zone represents the portion of the bandwith allocated to static services, with display of both
bit rate types: leased line (LL) and static IP (ATM) bit rate.
The dynamic zone represents the portion of the bandwidth allocated to the dynamic services: the
dynamic IP services.
116/302
182
Issue 01 - April 2001 - Draft 04
3CC12424AAAA TQ BJA 01
Note : The available bit rate depends on the traffic type allocated: leased lines, static or dynamic IP.
Note : The dynamic zone is the zone remaining available, corresponding to the total bandwidth minus
the static zone; the static zone corresponds to the static IP service bit rate.
The overbooking factor limit (OFL) is a value defined by the operator (until 10 as maximum) and can
be modified at any time depending on radio resource requirements: if the operator wishes to offer more
services than the system can physically provide simultaneously on the available bandwidth, he defines
this value which will represent a risk level of dynamic degraded service.
Note : When OFL = 1 (default value), it corresponds to the system physical limit assigned to the dynamic zone (= width of bandwidth).
If OFL = 2, double the dynamic zone physical bandwidth can be used for dynamic IP services.
Overbooking limit
Current overbooking (orange zone): < 1
means that there is no overbooking
IP traffic is measured according to «ATM» Rate = 66.5 Kbps,
whereas LL is measured with rate = 64 Kbps

4.8 NE management
As soon as the 7390LT is connected to the NE, it keeps a log of all the events taking place between the
Agent (NE) and the Manager (7390 LT) for the corresponding part of the supervised NE. This supervision
tool is mainly used as a log file to be used for maintenance purpose (see Chapter 6 Operation and
maintenance).

NE supervised means that the agent sends to the manager all the events related to the network element.
When the NE is supervised, the «Start NE Supervision» button is disabled.
When the NE is not supervised, the «Stop NE Supervision» button is disabled. The manager has lost
its synchronization with the agent. BS and NT are not supervised and events are not received.
Starting the NE supervision implies a total NE upload, because it is the only way to align again the LT
