Outdoor Unit Settings2.5 Verifying commissioningIt is recommended to monitor the hop for at least half an hour after all settingshave been made at both ends of the hop. Reset the statistics and the error countersand let the hop operate for half an hour (or longer, if desired). After the time haspassed, check that the signal quality statistics and the error counters do not showany undesired values (see Section 3.2.).If the signal quality is OK (unavailability time = 0) and there are no unexpectedalarms, the commissioning of the hop is complete. If there occurs anyunavailability time during the monitoring, repeat the monitoring.
Maintaining Nokia MetroHopperDN99611394 © Nokia Networks Oy 17 (42)Issue 2-0 en3Maintaining Nokia MetroHopperThis chapter contains the following information:• preventive maintenance• performance monitoring• replacing or removing equipment.3.1 Preventive maintenanceMaintenance of the radio includes measurements which do not interfere with thecommunication. Measurements which do interfere with the communication canalso be conducted when the radio is in operation, provided that the measurementsare performed at a time when there is no traffic or the traffic can be rerouted. Withthe Nokia Network Management System (NMS), service measurements can beperformed in a centralised manner for the entire network without having to movephysically from station to station. However, any measurements performed withexternal measuring instruments must be conducted locally.Record the measurements so that they can be compared with earlier results andused to detect significant changes in the results. Store the measurement records atthe location where the measurements are conducted, that is, the records ofcentralised measurements in the central monitoring room, and the records ofexternal measurements at the equipment station.3.2 Performance monitoringThe indoor units record information regarding the performance of the networkelement.The performance information is divided into three areas:
Commissioning and Maintenance18 (42) © Nokia Networks Oy DN99611394Issue2-0en• measurements• error counters• signal quality statistics.Each of these is available from the Measurements or Statistics menu in the nodemanager, in some cases, from the toolbar.The measurement and error counter windows both display information about theperformance of the network element and its current operating condition. Thestatistics are collected for the signal.3.2.1 MeasurementsThe Interface Measurements window, which is opened from Transmission /FXC RRI →Measurements, displays selected information about the networkelement. This information is in the form of, for example, bit error rates andvoltage or power levels recorded from particular units inside the functionalentities of the network element.Monitoring measurementsThese values are automatically refreshed according to the time interval that youcan enter into the Auto Refresh field. If the refresh rate is set to 0 seconds, therefresh is done only once. The values can also be manually refreshed by clickingthe Refresh button.3.2.2 Error countersError counters in the network element record the number of times that an errorhad occurred in a particular unit or functional entity.Click Transmission / FXC RRI →Statistics to open the Statistics dialog box,which displays the error counters for the selected interface.All error counters in the network element can be reset to zero by selecting thecorresponding Reset radio button in the Statistics dialog box.3.2.3 Reading statisticsThe statistics that the network element records for signal quality are kept to ITU-T recommendation G.826. These values are available for 2M platform interfacesof FXC RRI (last 16 measurements).The following statistics are recorded:

This will open the Statistics dialog box, in which you can choosethe interface for which the statistics will be displayed.It is possible to reset all the signal quality statistics by selecting the correspondingReset radio button in the Statistics dialog box.3.3 Using loopbacksEach unit contains several loopback points, which you can set manually to test thenode. These loopbacks are accessed by clicking Transmission / FXC RRI →Interface loops on the menu.The loopback status can change without the user changing it, for example, if thetime-out has been reached. Because of this, the Loopback window has its ownprivate status bar, which shows the last time the status of the loopbacks waschecked, and how long till the next refresh. You can set the refresh value byselecting Manage →Service Interface on the menu and entering the requiredvalue on the Time-outs tab.Table 1.
