Page 22: About This Document
MetroHub Manager software included in the Nokia SiteWizard CD-ROM. This document describes only outdoor unit -related settings and functions. To commission Nokia MetroHopper with FC RRI or FXC RRI you need also Nokia MetroSite GSM BTS User Manual or Nokia MetroHub User Manual which describe all node-level and RRI-related settings and functions.
Page 24: Commissioning Nokia Metrohopper
This chapter describes the commissioning process of the Nokia MetroHopper Radio. All commissioning tasks are performed with Nokia BTS Manager in case the radio is used with Nokia MetroSite GSM BTS or with Nokia MetroHub Manager in case the radio is used with Nokia MetroHub.
Page 25: Commissioning With Nokia Bts Manager
Flexbus in use before you can proceed to the next page. Note The radio capacity of Nokia MetroHopper is fixed to 4 x 2 Mbit/s. Note If the transmission unit is FC RRI, only Flexbus 1 settings are displayed.
Page 26 Commissioning Nokia MetroHopper Figure 1. Flexbus settings page The MetroHopper General Settings page is displayed next. On this page, you can select the settings for the outdoor unit connected to the Flexbus 1 interface. • Hop Mode: one of the terminals forming a radio hop must be configured as the master and the other end as the slave.
Page 27 Commissioning and Maintenance Figure 2. MetroHopper General Settings page If the transmission unit in use is FXC RRI, define the settings for the Flexbus interface 2 and the connected outdoor unit as described above. If the transmission unit is FC RRI, only one Flexbus is available and you can proceed to step 4 directly.
Page 28: Commissioning With Nokia Metrohub Manager
Configuring identifications and settings This section describes how to view or change outdoor unit related identifications or settings with Nokia BTS Manager or Nokia MetroHub Manager. When you are using Nokia BTS Manager, all Nokia MetroHopper related identifications and settings are accessed through the Transmission menu. In case you are using Nokia MetroHub Manager, these are found under the FXC RRI menu.
Page 29: Identifications
Select the required Flexbus interface. In these windows you can enable or disable Flexbus interfaces and set the appropriate capacity. Note that with Nokia MetroHopper the capacity is fixed to 4 x 2 Mbit/s. You can also switch the OU power feed on or off.
Page 30 Commissioning Nokia MetroHopper Hop end mode One of the terminals forming a hop must be configured as the master and the other as the slave. In order to change the hop end mode, you will need to recommission the hop by using Radio Wizard.
Page 31: Verifying Commissioning
If the signal quality is OK (unavailability time = 0) and there are no unexpected alarms, the commissioning of the hop is complete. If there occurs any unavailability time during the monitoring, repeat the monitoring. 16 (42) © Nokia Networks Oy DN99611394 Issue 2-0 en...
Page 32: Maintaining Nokia Metrohopper
With the Nokia Network Management System (NMS), service measurements can be performed in a centralised manner for the entire network without having to move physically from station to station.
Page 33: Measurements
The statistics that the network element records for signal quality are kept to ITU- T recommendation G.826. These values are available for 2M platform interfaces of FXC RRI (last 16 measurements). The following statistics are recorded: 18 (42) © Nokia Networks Oy DN99611394 Issue 2-0 en...
Page 34: Using Loopbacks
Errored Blocks as speciﬁed in G.826 1) G.826 gives two deﬁnitions for SES. In Nokia Q1, the deﬁnition of SES as “≥30% errored blocks in one-second period" is adopted. To see the signal quality counters, click Transmission / FXC RRI → Statistics on the menu.
Page 35 To set a loopback point: Select the required interface from the list. Define the required loop type by selecting the appropriate radio button. Send the changes to the node by clicking the Send button. 20 (42) © Nokia Networks Oy DN99611394 Issue 2-0 en...
Page 36: Replacing Or Removing Outdoor Unit
Maintaining Nokia MetroHopper Figure 4. Interface loops window Note When a loopback has been set, no other settings will take effect until the equipment is returned to normal state. To force the equipment to normal state, select the Normal radio button and click the Send button.
Page 37 If the units to be removed or replaced carry important traffic, reroute the traffic before starting the work. The removal or replacement of equipment cuts traffic. To replace or remove the Nokia MetroHopper outdoor unit: Set the OU to Receiving only transmitter mode (see Section ). This ensures that the radio will not transmit accidentally in case it is reinstalled.

Page 107: Alignment With Agc Voltage
Attaching the radio section Alignment with AGC voltage In order to obtain maximum alignment accuracy, Nokia MetroHopper can be fine aligned also by measuring the AGC (Automatic Gain Control) voltage which is inversely proportional to the input level of the signal received from the radio hop.
Page 108: Uninstalling The Outdoor Unit
Installing Nokia MetroHopper outdoor unit Adjust the fine alignment bars with a spanner as described in Section 4.5 until you find the minimum AGC voltage value. See Table 1 for approximate voltage values at different Rx input levels. Lock the fine alignment bars.
Page 109 Installation To uninstall a radio: Turn the power supply to the OU off with Nokia Hopper Manager (Refer to Commissioning and Maintenance for more information). Disconnect the Flexbus cable (see Section 5.2). Disconnect the grounding wire (see Section 5.1). Disconnect the synchronisation cable, if in use (see Section 5.3).
