BTS software (SW) uses these alarms as a basis for internal diagnosis and fault reporting through the Radio Network Controller (RNC) to the Operations Support System (OSS) and BTS Site Manager. DN7095963 Issue 2-0 en # Nokia Corporation 7 (125) MENU BTS Alarm Descriptions 8 (125) # Nokia Corporation DN7095963 Issue 2-0 en MENU Alarm handling 2 Alarm handling 2.1 General Base Station (BTS) alarm handling is based on unit state information. It prevents the sending of unnecessary alarms by checking and updating unit states. Fault messages come either from hardware devices or software components. The faults are system or hardware specific. The Fault Diagnosis System creates upper network alarms, which are based on an analysis of the faults, and sends them to the BTS Site Manager and RNC. In addition to routing to the RNC, the alarms are buffered and, for example, active BTS alarms can be seen from the RNC. NetAct is used for handling the BTS alarms. The BTS is able to maintain alarm handling after it has been commissioned and is in a configured state. During the start-up, the BTS waits for the real time clock from the Network Time Protocol (NTP) server, and the fault diagnosis starts after the time has been set or a time-out has been detected. If the BTS is unable to set the time using the NTP server, the default time (1.1.1990) will be used. 2.2 Instructions for solving problems When starting to solve a problem, first refer to the instructions given in the individual alarm descriptions. Verify the configuration of a BTS by checking the commissioning, cabling and correct installation of the units at the BTS. Make sure the environment does not cause the fault. For more information on implementation, normal daily operations, maintenance, and troubleshooting, refer to Nokia UltraSite WCDMA Base Station (BTS) family, Nokia MetroSite WCDMA Base Station and Nokia MetroSite 50 WCDMA Base Station Product Documentation sets. DN7095963 Issue 2-0 en # Nokia Corporation 9 (125) MENU BTS Alarm Descriptions If an active alarm is a 'Start' alarm, a unit block/unblock (if supported by the unit) or site reset is required to cancel it. If the site reset or unit block/unblock does not help, replace the faulty unit. See the fields 'Source of the alarm' and 'Instructions' in the corresponding alarm description. If you cannot solve the problem by yourself, contact the local Help Desk. 2.3 Blocking and locking The 'Cancel' alarms are always sent to hosts (BTS Site Manager and RNC). When the unit or cell is in a blocked state, the 'Start' alarms are only sent to the BTS Site Manager. When a unit or cell is unblocked, all the active alarms related to the unblocked unit or cell are automatically sent to the hosts. The locked or unlocked state of a cell has no effect on sending alarms to the hosts. 2.4 Identifying faulty units This section describes how the plug-in units are identified in different WCDMA BTS cabinets and how a faulty unit can be located with the NetAct system. See below the explanations of an example 'Alarm Dialog' window for different fields in Figure NetAct Alarms window. . 7652 *: reported severity . Suppl info field: fault name .

The cause of the alarm can be: 1. The Iub reference frequency has changed due to a fault in the transmission network synchronisation (which in turn is caused by an equipment fault or a setting error). Note that if the network synchronisation malfunction lasts a long time, the alarm is cancelled when the BTS frequency reaches the faulty Iub synchronisation. The alarm can also be activated if the faulty Iub synchronisation is corrected and there is again the difference of 0.2 ppm or more. The alarm is cancelled whenever the difference becomes smaller than 0.2 ppm. 46 (125) # Nokia Corporation DN7095963 Issue 2-0 en MENU Alarms 2. The Iub reference frequency fluctuates continuously due to a great deal of jitter/ wander in the transmission network. The alarm is continuously activated/ cancelled (however, the alarming state may predominate). There is always some jitter/wander in the transmission network; the limits are defined in ITU-T G.823/824/825. 3. If the BTS integrated transport part receives the synchronisation information via the 2.048 MHz synchronisation input (external clock source), the alarm situation may be caused by a fault of that signal. In that case, the alarm behaviour notifications listed with the Iub signal (see above) are also valid in this case. 4. There is an equipment fault in the BTS. The equipment fault is, however, not the most common reason. Normally the reason can be found in the Iub/ reference signal behaviour (see the descriptions above). Note that if the alarm 7651 BASE STATION OPERATION DEGRADED: 'WSC oven oscillator fault' becomes active, it may cause the alarm 7652 BASE STATION NOTIFICATION: 'Difference between BTS master clock and reference frequency' to cancel. DN7095963 Issue 2-0 en Event type Start / Cancel Unit status Degraded Effect This fault does not immediately affect the operations of the BTS, but it is a notification that the BTS frequency deviates from the Iub reference. The BTS master clock tuning continues in spite of the alarm, but because the BTS master clock adjustment is quite slow in order to filter the instabilities of the Iub interface, it takes some time (even several hours) before the BTS operations start to be affected. Reported alarms 7652 BASE STATION NOTIFICATION LED display Blinking red (WSC/WMC) Instructions Because there are several possibilities for the alarm activation, a BTS Clock Frequency History feature has been developed. The stored history data can be accessed via the BTS Site Manager. # Nokia Corporation 47 (125) MENU BTS Alarm Descriptions The history data can be used as a tool for finding out the reason for the fault/alarm situation (for further instructions about the history feature, see the online Help of the BTS Site Manager). Depending on the possible reason, follow the instructions below: 1. In case of fault in the transmission network synchronisation, the network synchronisation must be corrected. The long-term accuracy of the Iub signal must be 0.015 ppm or better (check the correct Iub accuracy by measuring it). No actions on the BTS are necessarily needed. 2. If the basic accuracy of the Iub signal is in order but there is too much instability, that is, the jitter/wander is outside the acceptable limits, the synchronisation of the transmission network must be corrected. The limits for the jitter/ wander are defined in the ITU-T G.823/ 824/825. No actions on the BTS are needed. 3. In case of BTS equipment fault, the location may be: a. Transport part . First check the alarms of the AXC node with the AXC Manager and act accordingly. . If there are no alarms, check the AXC synchronisation settings. b. WSC unit . If both the Iub reference signal accuracy and the AXC node are in order but the WSC unit is still alarming, run the fast tuning with the BTS Site Manager. . If the alarm is still active after the fast tuning is finished, reset the site. . If that does not help, replace the WSC unit. Note that if the reason is in the transmission network synchronisation, replacing the WSC unit does not correct the situation. Furthermore, the alarm activity (frequent alarms/ cancels) points to instability in the transmission network, not to a fault in the unit. 48 (125) # Nokia Corporation DN7095963 Issue 2-0 en MENU Alarms 4. After the fault situation has been cleared, the BTS master clock may also require tuning because the BTS master clock adjustment is quite slow. The tuning may be done: . manually by changing the DAC word (during a site visit) . or with fast tuning, in which the BTS master clock is tuned in a few minutes automatically near the Iub reference (normal tuning takes care of the fine tuning). Note, however, that the fast tuning should only be used in case the Iub reference signal is known as a good one. Otherwise the BTS frequency may be tuned into a totally incorrect value, causing serious problems in the network performance. Background information: The principle is that in the mobile network, the synchronisation goes from MSC => RNC => BTS. But in reality that chain might be broken somewhere and, for example, when using leased lines, the BTS may take the reference synchronisation from the transmission network of another operator. This does not harm the system if the synchronisation of the leased line service provider is also accurate/stabile enough. The BTS uses the incoming synchronisation signal as a reference for the Air interface, the accuracy requirement of which is set by 3GPP. 4.29 DN7095963 Issue 2-0 en Diversity branch masthead amplifier fault Name Diversity branch masthead amplifier fault Product Supreme; Optima; Optima IBBU; Optima Compact RF Extension; MetroSite; Triplemode; MetroSite 50 Detecting unit WAF Fault source (WAF), MHA Meaning The operating voltage of the Mast Head Amplifier (MHA) is supplied through the Bias-T from the WAF.
