Exercise 9: Connecting the Access card and adding it to the results

Watch the video presentation and/or read the full text below

The next step is to relate the first of these resources to the service. Before we proceed, let’s rearrange the icons in anticipation of the likely connections.

  1. Click and drag each resource in turn to arrange them as shown below.
  2. Press <Ctrl+Q> to connect the service to the Access card resource, being careful to use the ‘quick-link target’ again to pre-select Basis = Connections (which means that each customer requires one port). The service is linked to the resource as illustrated.

Figure 21: Arranging the icons, and connecting the Access card resource

Note: you may consider that each customer requires an interface, that the interface in turn connects to a port on the card, and therefore that we should instead connect from Optical interface to Access card. However, each interface is dedicated to a single customer, so the same outcome is achieved more straightforwardly by connecting from the service directly.

Now let’s examine the results for the Access card (and learn a useful shortcut too):

  1. Run the model, and skip the likely warnings about the lack of requirements for the other resources. The Results program is activated.
  2. Locate the existing graph of Installed and Incremental Units, and double-click the minor title, Optical interface. This is an intuitive shortcut for the change selections command, and the Change Selections dialog is displayed.
  3. Double-click Access card on the left to add it to the Selected list, double-click Optical interface to remove it, and press OK. Results for the Access card are now shown. The total approaches ‘60 something’; i.e., approximately 1000/16.
  4. Using a similar technique, but this time retaining the Optical interface, add the Access card to the Capital Expenditure and Operating Costs graphs. The combined results are stacked to indicate the total capex and opex.

You can check the cost numbers in your own time, but let’s first take a more critical look at the deployment. Do we really have enough cards? Where are the customers?
