Chapter 1 Welcome

Figure 1-1 Q-NET™ Bandwidth Manager Q-NET™ is a scalable satellite communications system that supports point-to-point and point-to-multipoint networks. Q-NET™ systems are based on a combination of Q-MultiFlex™ point-to-multipoint units and Q-Flex™ or Q-Lite™ satellite modems. The Q-Flex™ is a versatile software-defined satellite modem that supports state-of-the-art modulation and error correction technology, including the highly efficient DVB-S2X standard. DVB-S2X, the successor to DVB-S2, is the most efficient and robust coding and modulation standard available for satellite transmission and supports transmission of modulations up to and including 64APSK. The Q-Lite™ is a compact form of the Q-Flex™, suitable for comms-on-the-move. The Q-MultiFlex™, a variant of the Q-Flex™, supports a modulator and up to 16 demodulators, enabling cost-effective point-to-multipoint IP operation. It is scalable to any network size. Q-NET™ has two complementary control applications:

• Q-NET™ Bandwidth Manager is a web browser application that provides transponder carrier planning and high-level system control, monitoring, recording and quality-of-service reporting. It runs on a server and supports any number of remote clients. It also supports a transactional database that stores all system configurations and events. It supports full backup redundancy, which can be in any location.


1-2

• Q-NET™ Navigator provides M&C control of all modems (and other network devices) in the system through a single application.

The two applications can be used together or in isolation from each other. The Bandwidth Manager is typically used by power users and in larger systems that require extensive high-level planning and coordination. Navigator is suited to day-to-day ‘hands-on’ operational control activities. This handbook will guide you through the process of using Bandwidth Manager in your Q-NET™ system.

Chapter 4 Overview

This chapter provides an overview of the Bandwidth Manager. Q-NET™ is in principle hubless and the Bandwidth Manager can be located anywhere in the network that has connectivity to the network equipment to be controlled. Usually it is positioned at a central site if this avoids or minimises the requirement for multiple satellite hops. The Bandwidth Manager enables users to plan and manage satellite bandwidth across the network. To set up multiple similar services, all of the links can be generated automatically using a template and then individual services can be customised as required. The tool will always use the available bandwidth in the most efficient manner. Once the plan is complete and is ready to be deployed, the Bandwidth Manager will apply the settings to the network. Bandwidth Manager is typically used to configure satellite modems to send carriers between hub and remote sites, whether point-to-point or point-to-multipoint (star/mesh). In principle, other types of network equipment (such as routers, switches, BUCs, etc.) can be controlled, which normally requires only the addition of a suitable software driver (translator). There are five steps involved in setting up a working network from the perspective of the Bandwidth Manager:

1. Details of network ground-segment resources, principally satellite modems, are entered.

2. Space-segment bandwidth and power resources (representing one or more transponders on one or multiple satellites) are entered.

3. Forward and return carriers are set up. 4. Links (normally bidirectional) are then created that associate the network carriers

with specific modem resources. 5. The above steps result in the creation of a carrier plan. This is then applied to the

network. An optional but advisable further step is to create one or more ‘topology’ views of the network that allow the status of all network equipment to be continuously monitored. Topology View supports alarm reporting, acknowledgement and masking of alarms, alarm drill down, etc. Network reports and analytics within Q-NET™ form part of the wider CodeMettle NMS and are documented separately.

Chapter 5 Bandwidth Manager Basic Layout

Bandwidth Manager is typically pre-installed on the network server hardware prior to delivery, or is installed later by, or under the supervision of, a Paradise or CodeMettle employee. The Bandwidth Manager is a widget on the CodeMettle NMS dashboard. To use it, open a web browser on a computer with internet access and enter the server’s IP address/URL on the address bar. A login window (Figure 5-1) will appear that controls access to the CodeMettle NMS.

Figure 5-1 Q-NET™ Bandwidth Manager Login Screen A valid username and password are required to access the NMS interface. Enter the provided username and password and select ‘Login’. The NMS dashboard then appears. The Bandwidth Manager Planning View is the default view (Figure 5-2).


5-2

Figure 5-2 Bandwidth Manager Planning View (no carriers) The Planning View displays C/N (Carrier to Noise) values vertically and transponder frequencies horizontally. In the upper right corner are a number of control icons (Figure 5-3).

Figure 5-3 Planning View Control Icons


5-3

The zoom icons control how much of the transponder frequency span is visible on the display. The Configure widget is used to enter and exit the carrier planning edit mode, which allows changes to be made to the plan. The Schedule View icon is used to enter Schedule View (Figure 5-4). This shows the transponder by carrier (top to bottom, representing increasing frequency over the transponder) and time (left to right).

Figure 5-4 Schedule View

You can return to the Planning View at any time by selecting ‘Planning’ from the Dashboard (Figure 5-5).

Figure 5-5 Selecting Planning View from the Dashboard

It is also possible to configure and view one or more system network diagrams. These can be used to view the current status of all network devices, for example. This is called Topology View (example shown in Figure 5-6) and can be selected from the Dashboard once a topology has been entered. The Topology Editor is documented in the CodeMettle NMS Administrator Manual.

Chapter 6 Spectrum Management

The Spectrum Manager is used to add, edit and delete transponder resources, which are referred to as managed bands. A managed band may be an entire transponder or a portion of a transponder that has been allocated by the satellite operator. (In principle, a managed band could span several transponders but typically it is more convenient to manage them separately.)

6.1 Adding a Managed Band

Satellite bandwidth is defined using the Spectrum Manager, which can also be used to monitor carrier spectrums and inform operators of any carrier issues. The Spectrum Manager is selected from the menu as shown in Figure 6-1.

Figure 6-1 Selecting the Spectrum Manager The spectrum manager opens in a new window (Figure 6-2). This presents a graph and three tabs (of which the View Spectrum tab is active by default).


6-2

Figure 6-2 Spectrum Manager Initial View Clicking on the Manage Spectrum tab results in the display shown in Figure 6-3.

Figure 6-3 Spectrum Manager Monitoring and Management Options Two tabs are presented, for Carrier Monitoring and Bandwidth Management, respectively. Clicking on the Bandwidth Management tab results in the display shown in Figure 6-4.


6-3

Figure 6-4 Bandwidth Management Screen within the Spectrum Manager This lists the managed bands that have been defined, as well as any bands that have been defined just for carrier monitoring purposes.

To add a new managed band, click the symbol, resulting in the display shown in Figure 6-5.


6-4

Figure 6-5 Adding a Managed Band Most of the required information will come from the satellite operator. Enter a Name, Description, Center Frequency and Bandwidth. In the example shown, the bandwidth will range from 4MHz to 6MHz. If the modems expect frequencies to be configured at IF or L-band then MHz values should be used rather than the absolute frequencies used by the transponder. The Noise Floor is a threshold that demarcates what spectrum data is valid (in relation to spectrum monitoring; if carriers are not being monitored then this value is irrelevant). All spectrum data above the noise value is considered valid; data below the noise floor is considered to be irrelevant noise. Selecting the Managed option activates the Protection Bandwidth option. This is a guard band at the edges of the managed band that prevents overlap with other bandwidth outside of the band. The guard band is applied within the allocated span. In the example above, once protection bandwidth is applied, the range available for carriers will be between 4.2MHz and 5.8MHz, as shown in Figure 6-6.


6-5

Figure 6-6 Adding a Guard Band When completed, click Save & Close, or Save & New to create another band. The list of managed bands is refreshed with the new entries. Close the spectrum manager by clicking the X in the upper right corner.

6.2 Configuring Transponder Bandwidth Resources

To complete the configuration of the managed bands, select the Configure icon on the Planning View as shown in Figure 6-7.

Figure 6-7 ‘Configure’ Icon for Selecting and Configuring Bandwidth

This results in a list of managed bands being displayed as shown in Figure 6-8.


6-6

Figure 6-8 Selecting from the available Managed Bands

The Configure window allows any managed band to be selected. There are configuration tabs for Transponder, Network and Carrier Settings.

6.2.1 Transponder Settings

The Transponder tab is shown in Figure 6-9. Typically the information to be entered will come from the satellite operator and from the link budget calculation.


6-7

Figure 6-9 Transponder Configuration Tab The transponder Frequency Span corresponds with that defined for the managed band. The transponder can optionally be given a different name from the managed band (for example, representing the name or type of the transponder). The Max Power and Pwr Conv Factor (power conversion factor) together represent the transponder’s power measurement. Power is calculated using a combination of factors including the modem’s received and transmitted power along with the Pwr Conv Factor. The Band Type is used for display purposes to help the operator relate more easily to the resources being managed. Once the data has been entered, the completed transponder tab should look similar to that shown in Figure 6-10.


6-8

Figure 6-10 Completed Transponder Configuration Tab The ruler below the frequency span graphically represents the bandwidth span.

6.2.2 Network Settings

Click the Network tab to open the window shown in Figure 6-11.

Figure 6-11 Network Configuration Tab


6-9

The network settings can be used as a shortcut to define the default configuration for the modems when using the transponder. The settings can be tailored later when configuring individual carriers and links. Once the data has been entered, the completed network tab should look similar to that shown in Figure 6-12.

Figure 6-12 Completed Network Configuration Tab Typically the required values will come from the link budget. The Layout can be set to either Link Pairs or TX/RX Grouped. Linking the pairs causes the transmit and receive carriers to reside side-by-side within the bandwidth as shown in Figure 6-13.


6-10

Figure 6-13 Linked Pairs of Carriers (Outbound/Inbound) Grouping the carriers will cause all of the transmit carriers to be contiguous and all of the receive carriers to be contiguous as shown in Figure 6-14.

Figure 6-14 Grouped Carriers (all Outbounds followed by all Inbounds) Note that the layout is applied when the links are generated. If the layout is changed after links have been generated then existing links are not affected by the change.


6-11

When creating links, the layout of carriers will always result in the most efficient use of bandwidth. This means that, regardless of the layout selected, if a link is added whereby one carrier will fit in a gap but not both then the two carriers will be separated, as shown in Figure 6-15.

Figure 6-15 Carrier Layout (where a carrier pair are separated to save bandwidth)

On the network configuration tab, the HPA setting refers to the high power amplifier for the transmit carrier since the forward carrier is configured but the receive site is measured. If the HPA setting is too high at the receiving modem, the forward (transmit) data path will be adjusted accordingly. The relationship between the transponder power (set in the transponder tab) and the HPA power is as follows. The transponder power is the overall power available for all of the carriers. HPA power is measured at the receive site. Both power settings are used to ensure that any restrictions set by the satellite provider are met. The values set here are applied across the band and the transponder overall; changes applied during planning are then displayed in the context of these values.

6.2.3 Carrier Settings

Click the Carrier Settings tab to open the window shown in Figure 6-16.


6-12

Figure 6-16 Carrier Settings Configuration Tab This tab is used to set a nominal carrier guard band and a nominal power level for all carriers, both of which can be adjusted for invididual carriers as required. Nominal power should be set to the lowest power level anticipated for any carrier. The carrier guard band is distinct from the Protection Bandwidth applied to the edges of the managed band (transponder) but serves the same purpose, in this case of preventing adjacent carriers from overlapping and interfering. The guard band is set as a percentage of the carrier span and is allocated external to the defined carrier bandwidth. (The Protection Bandwidth by contrast is assigned from within the managed band.) The relationship between carrier and transponder (managed band) guard bands is shown in Figure 6-17.


6-13

Figure 6-17 Relationship between Carrier and Transponder Guard Bands Clicking Save saves the values entered on all of the tabs and closes the Configure window.

Chapter 7 Modem Resources

Bandwidth Manager supports the ability to add and edit multiple types of system resources. For the purposes of bandwidth management (in contrast to other NMS functions documented elsewhere) this section focuses on the network’s modem resources. To add or edit modem resources, select the Administration tool from the main menu as shown in Figure 7-1.

Figure 7-1 Adding System Resources using the Administration Tool Next, select the Resource Management option shown in Figure 7-2.


7-2

Figure 7-2 System Administration Window

This will result in the screen shown in Figure 7-3 being displayed.

Figure 7-3 Resource Management Window

Selecting Resources will display the screen shown in Figure 7-4 (this will initially be empty when no modem resources have been defined).


7-3

Figure 7-4 Modem Resource Window

To add a new modem, click the symbol, resulting in the display shown in Figure 7-5.


7-4

Figure 7-5 Adding a new Modem Resource

A name and description should be entered for the modem. Communications with Q-NET™ modems is via SNMP. Selecting the Browse button associated with Transport brings up the windown shown in Figure 7-6. The SNMP transport option should be selected.


7-5

Figure 7-6 Selecting the Transport Mechanism (for modem communications)

Once SNMP has been selected, the modem resource windown changes to add SNMP options as shown in Figure 7-7. These additional fields can be edited as appropriate for the network but as a minimum the IP Address should be changed to a valid address for the modem (a subnet mask is not required).

Figure 7-7 Modem Resource Window for use with SNMP

In addition, to selecting SNMP, a specific SNMP MIB has to be selected for use with the modem (this will vary with the modem type). For Q-Flex™ modems, select the MIB shown in Figure 7-8.


7-6

Figure 7-8 Selecting the SNMP MIB (for modem communications)

To complete the basic modem configuration, select the Properties tab from the Modem Resource window (shown in Figure 7-7). This will display the window shown in Figure 7-9.

Figure 7-9 Modem Properties Window

Select the Built-in Properties dropdown box. This will display a large list of built-in properties that can be assigned to system resources including modems (shown in Figure 7-10).


7-7

Figure 7-10 Resource Built-In Properties (in the Properties Window) As a minimum, select either the Hub Modem or Remote Modem property as appropriate

for the type of modem and click the symbol beside the built-in-properties dropdown box. The result should look similar to the window shown in Figure 7-11.

Figure 7-11 Modem Properties Window (after assigning modem type) To save the modem configuration, select the green tick mark (or the red cross to cancel the edit). In addition to the basic modem configuration explained so far, the modem resource window includes a Rack tab that can be used to build a rack view of the network (see the example in Figure 7-12). When a system fault occurs, this is useful for drilling down to the actual rack position of the specific piece of equipment that has generated the fault.


7-8

Figure 7-12 Rack View

The Rack tab is shown in Figure 7-13. For each modem, a rack name should be entered along with the height of the modem (in rack units) and the position of the modem in the rack. Rack View can be selected from the Dashboard.

Figure 7-13 Rack Tab

When all modem resources have been added and saved, close all of the resource and administration windows.


8-1

Chapter 8 Carriers and Links

Once the space segment and ground segment resources have been defined, carriers and links can be added to the managed bands. This is done through the Planning View, which can be selected from the Dashboard. Once the managed band has been selected, clicking the Cog icon (Figure 8-1) allows the carrier plan for the transponder bandwidth to be edited.

Figure 8-1 Planning View Cog Icon (enters/exits Edit mode) When in the edit mode, a new area appears below the main view as shown in Figure 8-2. On the left side are two tabs: Carriers and Links.

Figure 8-2 ‘Carriers’ and ‘Links’ Tabs in Planning View None of the changes made while still in the planning mode affect the actual network and all of the changes can be cancelled before exiting if necessary, leaving the network as it


8-2

was. It is also possible to save the plan and resume work later but without the changes being propogated to the network. Multiple plans may therefore exist, for the same or different resources, and may be applied to the network, or subsets of the network, whenever required. This allows progressive planning where future network changes are worked out in every detail in advance, ready to be deployed when required.

8.1 Adding Carriers

Any number of carriers can be created for managed bands. Clicking the green plus symbol in the Carriers tab displays Figure 8-3.

Figure 8-3 Adding a Carrier A carrier is defined by a name, center frequency, bandwidth span and a C/N (carrier-to-noise) level. Note that the center frequency and bandwidth values can be entered as decimal numbers with any degree of resolution. Later, the FEC, modulation, FEC rate and roll-off for the forward and return carriers will be set up as part of the link and will be allocated to modem resources. This can be done manually for each carrier and link or the entered information can be used as a template for automatically generating as many links as required. If links and carriers are generated automatically then the carrier name is constructed such that it consists of the central frequency and an indication of whether it is a forward or return carrier. The Schedule icon manages when the carrier is active. (By default, the carrier will always be active.) Clicking on the icon displays the window shown in Figure 8-4. Scheduling can be done at either the carrier level or the link level. When scheduling at the link level, the carriers can optionally be generated using the default settings for the managed band and therefore do not need to be set up in advance. Scheduling at the carrier level requires the transmit and receive carriers to be set identically.


8-3

Figure 8-4 Scheduling a Carrier Setting the carrier to be active for a specific date and time brings up the window shown in Figure 8-5.

Figure 8-5 Scheduling a Carrier for a specific time Click the Calendar icons to choose the start and end dates (see Figure 8-6).


8-4

Figure 8-6 Selecting the Start Date & Time Once the times have been entered, the window will look similar to Figure 8-7.

Figure 8-7 Scheduled Carrier Start/End Times To set up a recurring carrier, click the Recurring option. This will display the window shown in Figure 8-8.


8-5

Figure 8-8 Scheduling a Recurring Carrier Select one or more days and choose the start and end times. The carrier will be activated for the same time and duration on each day that has been selected. Click Save to commit the schedule. When the fields are completed, click Add carrier (Figure 8-3). Follow the same procedure for the return path. The carriers are added to the Carriers tab (Figure 8-9).

Figure 8-9 Carrier Tab after adding Carriers

To edit a carrier, select it on the list and adjust the values in the fields on the right hand side (Figure 8-10). Once the changes are complete, select the green tick symbol in order to save the changes.


8-6

Figure 8-10 Editing a Carrier

8.2 Adding Links

Once the forward and return carriers have been created, they need to be linked and assigned to modems. Click the Links tab (Figure 8-2) followed by the Plus symbol. This will show the window in Figure 8-11.

Figure 8-11 Adding a Link Enter a name for the link and select a color. Colors are used to visually associate the link’s forward and return carriers. Select the FWD Modem from the list (which will be restricted to the modems that were defined with a property of hubModem set to true, as shown in Figure 7-11). Select the Transmit Config forward carrier from the list of forward carriers. (This configuration will be used in this link and any other links generated from this definition.) The guard band is set in accordance with the default set earlier under the Carrier settings but can be changed if required. The return carrier and modem are set up in a similar way (a return modem has the property remModem set to true). (See Figure 8-12.)


8-7

Figure 8-12 Selecting the Link Return Modem The Schedule icon can be used to change the link from the default of always being active to being scheduled for a particular time (one-off or recurring). Although this can be done when configuring the carriers, doing it as part of the link setup configures both carriers at the same time and ensures they are synchronised to be active at the same time. Once the changes are complete, click on Add link. The entry is added to the Links list, shaded in the selected color. The carriers in the Planning View are also now shaded in that color (Figure 8-13).

Figure 8-13 Selecting the Link Return Modem


8-8

A carrier’s details can be viewed by moving the mouse over the carrier (Figure 8-14).

Figure 8-14 Carrier Tooltip Information

8.3 Link Auto-generation

Once carriers and a link have been created that can be used as a template, further links can be automatically generated based on the current forward and return carrier configurations. The links can be generated to fill the available bandwidth in the most efficient manner, while verifying HPA and transponder power usage remains within the available resources. Note that links that are generated automatically use the default values set in the mangaged band configuration tab (Figure 8-15) for data rate, FEC, etc.


8-9

Figure 8-15 Default Link Settings Under Full Spectrum in Figure 8-16, shows the full managed bandwidth at all times (in contrast to the main view, which may be zoomed into just part of the bandwidth). This makes it easy to see how much of the available bandwidth has been used.

Figure 8-16 Full Spectrum Window (bottom, right hand side) The same area also contains tools for generating additional links based on the current settings and for applying the plan to the network. A dropdown box (Figure 8-17) allows the selection of the number of links to be generated.


8-10

Figure 8-17 Setting the number of Links to Generate Clicking Generate Links (Figure 8-18) generates the additional links.

Figure 8-18 Generating Additional Links The carriers and links are then generated and a window is shown (Figure 8-19) to allow the manual allocation of modems to the forward and return carriers.

Figure 8-19 Auto-generated Links Once modems and link colors have been assigned, the window should look similar to Figure 8-20.


8-11

Figure 8-20 Auto-generated Links (with modems manually assigned) When complete, click Save Links. Figure 8-21 shows the main Planning View after the generation of the links.

Figure 8-21 Planning View (after link generation) The main view and the Full Spectrum view now display the automatically generated links. Note that automatically generated links are scheduled to always be active by default.

8.4 Editing Carriers

To edit the current plan, click the Configure cog in the upper right corner (Figure 8-22).


8-12

Figure 8-22 Planning View Edit Mode With the Carriers tab selected in the lower pane, click on the carrier’s name to view its settings (Figure 8-23).

Figure 8-23 Carrier Edit Mode To adjust the center frequency, use the arrows or enter the value directly. The carrier is moved accordingly (see the example shown in Figure 8-24).

Figure 8-24 Moving Carrier Center Frequency


8-13

To modify the carrier’s bandwidth, select the icon next to the bandwidth field (Figure 8-25).

Figure 8-25 Carrier Bandwidth Edit Mode

The data rate determines the carrier bandwidth as shown in Figure 8-26.

Figure 8-26 Changing Carrier Data Rate

Modify the data rate with the arrows or enter the new value directly. The bandwidth is updated to show the new value. If the frequency span becomes too wide for the carrier to remain at the assigned center frequency then the carrier will be moved to another part of the transponder. Click Apply Changes. The carrier is then updated (Figure 8-27). In this example, the bandwidth was increased.


8-14

Figure 8-27 Carrier following change in data rate To set or change the carrier’s active status, click the Schedule icon and follow the same procedure outlined earlier. If the carrier is part of pair, its counterpart must also be scheduled (or alternatively, both can be managed together by scheduling the link). To see the bandwidth span taken up by the carrier’s guard band, click Show Guard Band (Figure 8-28). A shaded area representing the guard band appears on each side of the carrier.


8-15

Figure 8-28 Carrier Guard Band A carrier can be deleted using the delete icon (Figure 8-29) but only if it is not part of a link (in which case the link must be deleted first).

To edit the current plan, click the Configure cog in the upper right corner (shown previously in Figure 8-22). Select the Links tab in the lower pane and select the link to be edited (Figure 8-30).

Figure 8-30 Editing a Link Any of the link’s values can be changed. Select the field’s dropdown arrow and choose a new value. Use the scroll bar to access the lower settings. Auto-generated links and carriers have a default of always being active; click the Schedule icon on the link to change this setting (Figure 8-31).

Figure 8-31 Changing the Link Schedule After editing the schedule settings, click Save. The changes are applied and reflected in the carrier schedule (Figure 8-32).

A confirmation message is displayed; confirm to complete the action. The deleted link’s carriers still exist and can be deleted or else associated with another link.

8.6 Power Monitoring

The Bandwidth Manager shows HPA and transponder power usage based on the total for all of the active links, as shown in Figure 8-33.


8-18

Figure 8-33 HPA and Transponder Power Indicators (right hand side) The power indicators show how much of the total power permitted has been used. The HPA value is the total power needed to transmit all of the hub carriers but does not include the power for the return carriers. The transponder power accounts for both remote and hub sites. If the maximum power allowance is close to exceeding the limit (90% or above) then the power indicator color changes to yellow. If the power allowance is exceeded the limit then the power indicator color changes to red. No action is taken to prevent the over-allocation of power resources. Moving the cursor over the power indicator bar (Figure 8-34) displays a tooltip that shows the maximum value allowed and the percentage of current usage.

Chapter 9 Schedule View

The Bandwidth Manager provides the abiltity to view managed bands (typically equating to transponders) based on schedules. Clicking the Schedule View icon in the upper right corner of the Planning View (shown previously in Figure 5-3) brings up the Schedule View (Figure 9-1).

Figure 9-1 Schedule View Note that the Schedule View cannot be used to edit the schedules, which can only be done in the Planning View. Carriers are listed on the left hand side while dates are listed across the top. Color in a row indicates that the associated carrier is active during this period. In Figure 5-3, all carriers are active at all displayed times, except one, which is scheduled for a particular date and time range. The view can be zoomed in (Figure 9-2) to see start and end hours within the days by clicking the Zoom In icon (or by clicking on the date field).

Chapter 10 Applying Settings to the Network

Once the carrier plan has been established, or has been changed, it is necessary to apply the plan to the network. This is done using the controls in the Full Spectrum view of the Planning View (Figure 10-1).

Figure 10-1 Full Spectrum Controls (Planning View)

Unlike traditional link deployment, the completed plan can be applied to the entire network, with configuration done in seconds or minutes (depending on the size of the network). While this is highly beneficial in terms of productivity and network down time, it has the potential for serious consequences for other users of the transponder if the plan is incorrect. Consequently, as a safeguard, Bandwidth Manager requires that the carriers themselves must be unmuted manually (if currently muted). If the carriers are already unmuted then any changes made using Bandwidth Manager will become effective without manual intervention. It is the responsibility of the user to ensure the carrier plan is correct.

When ready, click Apply Settings to Network to configure the network equipment. A confirmation message as shown in Figure 10-2 is seen.
