3CC12426AAAA TQ BJA 01 Issue 01 - April 2001 - Draft 04 141/3462344.5.1 – Base Station SupervisionTo Start or 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 inthe status bar indicates to the operator that the equipment is not supervised. Besides, not supervisedstatus implies that no action can be performed on the BS from the LT manager. Therefore, if the BS isnot supervised then no alarm is sent to the BS element. So, not supervision state implies alarms notallowed (the «Allow BS Alarms» button is disabled).To Allow or Inhibit the alarms of the Base Station:BS Alarms allowed means that all the alarms present in the BS equipment will be reported to the LTmanager.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 statusled boards in the BS appears in grey colour to indicate that it is unknown if the boards have or do nothave alarms present.Click on the icon to start the supervision of the Base Station.Click on the icon to stop the supervision 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.

Then, no action can beapplied over it, so all the "Apply" buttons are disabled. Therefore it implies that the alarms on this NT arenot allowed (the "Allow NT Alarms" button is disabled).To Allow or Inhibit the alarms of the NT:NT Alarms allowed means that all the alarms present in the NT equipment will be reported to the LTmanager.Allowing or inhibiting alarms on NTs have to be done one by one. It is not possible to allow or inhibitalarms 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.

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 circuitemulation via the leased line.STATIC SERVICES CONFIGURATION MAY CAUSE DYNAMIC IPSERVICES TO BE SHUT DOWN
168/346 Issue 01 - April 2001 - Draft 04 3CC12426AAAA TQ BJA 012344.7.3.2 – Access to the radio pre-configuration– Downstream channelsPolicing: is a buffer management function that implements intelligent discard mechanisms to preventbuffer overflows.Overbooking:– limit = 0 means that overbooking has no sense because in this upstream dynamic traffic is not al-lowed,To access on-demand services management and proceed with radio pre-configuration, click on the button shown here (in the button bar of the BS Detailsscreen).Click here to cancel the on-demand services management modificationsClick here to exit the on-demand services management windowClick here to take into account the system on-demand services allocationClick on the arrow to enable Service of RRM.

3CC12426AAAA TQ BJA 01 Issue 01 - April 2001 - Draft 04 169/346234– limit = 1 means no overbooking is allowed,– limit > 1 means it is possible to use more bandwidth than the physical one.– Upstream channelsCall Admission Control Strategy:–Guaranteed MCR, allows the CAC to deny connection to an RRM port if the current sum of theconnected RRM ports does not allow to accept the new RRM port without exceeding the dynamicresources.Degraded MCR allowed:– allows the CAC to accept every connection request. In this case, congestion event may happenand the RRM scheduler will need to degrade the MCR contract parameter of each connectedRRM port, up to its "maximum degraded MCR".4.7.4 – Bandwidth allocationThe 7390LT offers the capacity to display radio resources reserved for traffic and therefore potentiallyavailable to create customer services.Nota: The system always runs in self management mode, but pre-configuration is possible to avoidshutdown during static service creation; thus the system automatically returns to self manage-ment mode if the capabilities are exceededTHE RADIO RESOURCES DISPLAYED CORRESPOND TO BANDWIDTH ALLOCATION AND NOT TO THE CURRENT TRAFFIC ONTHE SERVICES CREATEDTo view reserved radio resources, click on the button shown here (SB Details screentoolbar).
170/346 Issue 01 - April 2001 - Draft 04 3CC12426AAAA TQ BJA 01234Meaning 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 thephysical 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 isdisplayed 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 zonechanges to red.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.IF THE ZONE IS ORANGE, CHECK THAT SIZE OF THE REMAINING DYNAMICZONE IS GREATER THAN THE LARGER DYNAMIC CROSS-CONNECTIONIF IT'S NOT THE CASE THIS CONNECTION WILL BE UNAVAILABLEClick on these tabs to display the radio resources of the other channels
