4.5.1 – 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 the icon to allow receiving the alarms of the Base Station.
Click on the 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.

– 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.

4.5.8 – Redundancy Radio capability
4.5.8.1 – Principle
Redundancy of the A7390 system corresponds to a 1+1 configuration and works in the "cold
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).
4.5.8.2 – Access to redundancy state display
To access consultation of the system redundancy state, click on the icon shown here,
that is in the button bar of the BS Details screen (§ 4.5 – Base Station Supervision).
The screen below is displayed:

and return to the BS Details screen
Note: The place of the boards into the DBS is directly linked to their role in redundancy (see § 4.5.8.3
Board and location in the cabinet according to their role in redundancy).
Note: The disponibility state on line corresponds to an active entity.

4.6.1 – NT Supervision
To Start or Stop the supervision of the NT:
Click on the icon to start the supervision of the NT.
Click on the 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 the icon to allow receiving the alarms of the NT.
Click on the 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.

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.

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 (SB 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

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.
