This document describes how to perform a basic configuration of a radio linkwith any of the above mentioned modems, including RTPC/ATPC. It could bea completion of a configuration made during the initial setup or a completelynew installation. The procedure is started indoors with a station radio cableconnecting the MMU and the RAU. For further instructions, see InstallingIndoor Equipment, Reference [8].

Also included are instructions on how to change an unprotected (1+0) RadioTerminal to a protected (1+1) Radio Terminal, and how to configure revertiveswitching over a protected (1+1) radio link.

Revertive switching enables an automatic switch to a path with lower attenuationin 1+1 protection hop with asymmetrical radio paths when no other faults areavailable. Revertive switching is applicable for the following configurations:

• 1+1 hot standby with asymmetrical power splitters

• 1+1 with space diversity

For information about configuring XPIC, see Configuring XPIC, Reference[7]. For information about configuring Adaptive Modulation, see ConfiguringAdaptive Modulation, Reference [5].

1.2 Planning Advice

To ensure proper node and network function, all configuration activities must beplanned in advance by skilled personnel.

It is recommended to read any applicable documents available in the Planningfolder and in the Site Engineering folder, such as:

• MINI-LINK 5.0 ETSI Compatibility

• MINI-LINK Radio Unit Compatibility

• Microwave Radio Propagation

• Recommendations for Positioning of Plug-In Units

1.3 Limitations

Ethernet LAN ports traffic and Radio Link traffic are transmitted through PtPbus to the NPU Ethernet switch.

The PtP bus has limited throughput capacity, which depends on the equipmentconfiguration. The following throughput capacities are available:

1 Gbps

AMM 20pB NPU1 C – MMU3 A in APU slot

2 Gbps

AMM 2pB / 6pC / 6pD NPU3 B/C – MMU3 A in all slots

AMM 20pB NPU1 C – MMU3 A in HSU slot

Configuration and Operations Tasks

Configuring Radio Link Using CLI

3 Configuration and Operations Tasks

To configure radio link parameters using CLI commands, perform the tasksdescribed in the following sections.

Note: The configuration can be prepared offline and transferred to thenode in the form of a CLI script, either remotely (when modifying theconfiguration for an installed node) or on site (when installing a newnode).

The following additional information is applicable when using CLI commands:

• How to start a CLI session and navigate between different commandmodes, see CLI User Guide, Reference [4].

• How to prepare a CLI script, see Preparing a CLI Script File Offline,Reference [16].

• How to transfer a CLI script on site, see Transferring a CLI Script File onSite, Reference [20].

• For a detailed description of each CLI command, see CLI Descriptions,Reference [3].

Consider the following rules for Radio Link configuration:

• Capacity or channel spacing (depending on MMU type) or and transmitterfrequency must be set before turning on the transmitter.

• Capacity or channel spacing (depending on MMU type) must be set to thesame value on both MMUs before protection is configured, but can bechanged after protection is set up.

• Output power mode must be set before the other output power commands.

• Maximum output power Automatic Transmit Power Control (ATPC), targetinput power far end, and output power Remote Transmit Power Control(RTPC) must be set after capacity or channel spacing commands.

• Target input power far end must be set after the hop is up and running.

• Protection is only set on one of the MMUs, the one in the slot with thelower number.

767/1543-HRA 901 20-V11 Uen G1 | 2014-05-13

Configuring Radio Link

• The two MMUs must use the same type of SDH connection, which isspecified using the CLI command interfaces. The interfaces cannot bechanged after protection is configured.

• It is not possible to switch between the protection modes hsb (hot standby)and wsb (working standby) directly, you must change the mode to unprot(unprotected) first.

• The Remote TX Switch Over function and alarms are disabled by default.Enabling the function and the alarms is only recommended for hops thathave high fade margins and low probability for deep flat or multi-pathfading. For more information about the Remote TX Switch Over function,see Troubleshooting Reference [21].

The DC bypass feature can be enabled or disabled at any time, but a warmrestart of the NE is needed for the change to have effect.

Note: If the installation has isolated grounding plane, the DC bypass featuremust be disabled. Disable the feature for installations with isolatedgrounding plane even if there currently are no MMU2 D, MMU2 H,MMU2 K, or MMU3 A modems. Use the command no rl powerdcbypassto disable the feature.

For information about configuring DC bypass feature, see Configuring NetworkElement Basics Reference [6].

For information about configuring Adaptive Modulation, see ConfiguringAdaptive Modulation, Reference [5]. For information about configuring XPIC,see Configuring XPIC, Reference [7].

3.6 Changing the Traffic Capacity of a Radio Terminal withMMU2 B/C/D/E/F/H or MMU3 A

This procedure describes how to change the traffic capacity of an unprotected(1+0) or protected (1+1) Radio Terminal for different types of MMU2s or MMU3As.

Before changing the capacity, change the output power to prevent linksaturation and interference with other links. This is especially important incase of static frame format, that is, when Adaptive Modulation is inactive. Anexample of how to evaluate the output power for compensating the possiblereduction of system gain is shown in Table 2.

Configuration and Operations Tasks

Table 2 Evaluating Output Power

Current Modulation Wanted Modulation Output Power

Increase the outputpower if the currentreceived power levelat the far-end terminalis below the threshold10-6 of the wantedmodulation.

512QAM

Decrease the outputpower if the currentlyreceived power level atthe far-end terminal ishigh (for example, inthe order of -30 dBm oreven higher) to preventnon-linearity problems.

128QAM

64QAM Nothing to remark

Which CLI command to use to verify or change the output power beforechanging the traffic capacity depends on the type of MMU. See the applicablesection in this document.

This example script changes the traffic capacity of an unprotected (1+0) orprotected (1+1) Radio Terminal with MMU2 B/C/E/F:

! In Global Configuration mode, configure capacity:! (config)#rl <SLOTNO> capacity <CAPACITY> //! modulation <MODULATION> frameformatversion <FRAMEFORMATVERSION>! This example sets the capacity to 2×2 Mbps with modulation! 16-qam:rl 3 capacity twoE1 modulation 16-qam

This example script changes the traffic capacity of an unprotected (1+0) orprotected (1+1) Radio Terminal with MMU2 D/H/K:

! In Global Configuration mode, configure capacity:! (config)#rl <SLOTNO> channelspace <CHANNELSPACE> //! modulation {<MODULATION>} license <LICENSE> //! tributaries <TRIBUTARIES> frameformatversion <FRAMEFORMATVERSION>! This example sets the channelspace to 28 MHz with! modulation 16-qam, 50 megabits, and 10 E1s for the MMU in slot 3:rl 3 channelspace 28 modulation 16-qam license 50 tributaries 10

4.6 Changing the Traffic Capacity of a Radio Terminal withMMU2 B/C/D/E/F/H/K or MMU3 A

This procedure describes how to change the traffic capacity of an unprotected(1+0) or protected (1+1) Radio Terminal.

Before changing the capacity, change the output power to prevent linksaturation and interference with other links. This is especially important incase of static frame format, that is, when Adaptive Modulation is inactive. Anexample of how to evaluate the output power for compensating the possiblereduction of system gain is shown in Table 3.

Table 3 Evaluating Output Power

Current Modulation Wanted Modulation Output Power

Increase the outputpower if the currentreceived power levelat the far-end terminalis below the threshold10-6 of the wantedmodulation.

512QAM

Decrease the outputpower if the currentlyreceived power level atthe far-end terminal ishigh (for example, inthe order of -30 dBm oreven higher) to preventnon-linearity problems.

128QAM

64QAM Nothing to remark

To change the traffic capacity:

1. In the Management Tree, right-click the applicable MMU2 B/C/D/E/F/H/Kor MMU3 A.

2. Point to Configure and click Configure Radio Link to open theMMU2 B/C/D/E/F/H/K Configuration or MMU3 A page.

3. Under RF, set the Output Power (dBm).

4. Click Save in the Toolbar to apply changes.

5. For both Near End Radio Terminal and Far End Radio Terminal, specifythe same values under Capacity. For more information, see the applicableMMU2 or MMU3 A configuring section in this document.

Configuration and Operations Tasks

Note: If an MMU2 C is configured with 16-QAM, consider the following:

• If you are configuring the MMU2 C for the first time (new unit)and you want to use the old frame format then you must choose16-QAM B and click Apply. Then the old frame format willappear in the drop down list and you can select that instead.

• If near and far end is running software release 3.1 or later,then it is recommended to use the new frame format denoted16-QAM B in the drop down list.

• If the hop contains RAU2 X on both or either side then it isrequired to upgrade the NE to software release 3.1 or laterand then use the new frame format denoted 16-QAM B in thedrop down list.

6. Under RF, select Transmitter On for both Near End Radio Terminal andFar End Radio Terminal.

7. Click Save in the Toolbar to apply changes.

8. In the Management Tree, right-click the applicable MMU2 B/C/D/E/F/H/Kor MMU3 A.

9. Click Alarms.

10. On the applicable MMU2 Alarms and Status page, make sure there areno active alarms.

4.7 Changing a 1+0 Radio Terminal to a 1+1 RadioTerminal with MMU2 B/C/D/E/F/H/K or MMU3 A

This procedure describes how to change an unprotected (1+0) Radio Terminalto a protected (1+1) Radio Terminal.

Note: 1+1 configurations are only possible if the units are placed inadjacent AMM positions according to specifications in Installing IndoorEquipment, Reference [8].

1. Insert the new MMU, see Adding a Plug-In Unit, Reference [2].

Note: If the new MMU is inserted in the lower (protected) position, theradio link needs to be reconfigured as a new 1+1 radio link, seeSection 4.1 on page 23 for MMU2 H/K, Section 4.4 on page 34 forMMU2 E/F, Section 4.5 on page 38 and Section 4.3 on page 30 forMMU2 B/C/D, or Section 4.2 on page 26 for MMU3 A.

2. In the Management Tree, right-click the MMU in the lowest position.

3. Point to Configure and click Configure Radio Link.

4. In the Mode list, select the protection mode, 1+1 Hot or 1+1 Work.

4.8 Configuring Enhanced Radio Link Bonding (MMU3 A)

It is possible to configure Enhanced Radio Link Bonding (EnRLB) in thefollowing two modes:

• 1+1 working standby

• 1+0 XPIC

Note: 1+1 configurations are only possible if the units are placed inadjacent AMM positions according to specifications in Installing IndoorEquipment, Reference [8].

To configure EnRLB, follow the instructions in Section 4.2 on page 26, butmake sure to set the mode on the MMU3 A Configuration page as follows:under Near-End Radio Terminal and the heading Terminal, select EnhancedRadio Link Bonding in the Mode list.

4.9 Configuring Revertive Switching with MMU2B/C/D/E/F/H/K or MMU3 A

Revertive Switching can be used when the Tx Radio or Rx Radio areasymmetrical over a protected (1+1) link.

For Tx, revertive switching can be used when an asymmetrical power splitteris used. If the radio with the highest output is set as Preferred Tx Radio, thesystem will automatically switch back to the radio with the highest output afterfor example a service.

For Rx, the receiver with the least fading should be set as Preferred Rx Radio.

This procedure describes how to configure Revertive Switching:

1. In the Management Tree, right-click one of the MMU2 B/C/D/E/F/H/Ksor MMU3 A.

2. Point to Configure and click General.
