Configuration File

This section describes the dial plan configuration file and how to manage it. From the Operations tab of the Dial Plan window, you can perform these tasks:

■ Accessing the Dial Plan

■ Creating Dial Plan Configuration Files

■ Importing and Exporting Dial Plan Configuration Files ■ Importing a User-Defined Dial Plan

■ Exporting (Saving) a Dial Plan Configuration File ■ Testing a Dial Plan

■ Generating a Dial Plan Report

■ Modifying a Dial Plan Configuration File

Accessing the Dial Plan

To import a dial plan configuration file and modify it, select NBX NetSet > Dial Plan > Operations. From this tab, you can access

customer-defined and default dial plans. Creating Dial Plan

Configuration Files

The simplest way to create a new dial plan is to model it after an existing one.

1 Go to the Operations tab.

2 Browse for a dial plan, or select one from the pull-down list. 3 Click Open to open the file in your browser.

4 Click Save As and save the dial plan as a new file.

You can now edit the file with an ASCII editor. After you customize the new dial plan, Import it to the NBX system. see “Importing and Exporting Dial Plan Configuration Files” on page 47.

3Com recommends that you enter these commands at the top of every dial plan configuration file:

Table Delete *

DestinationRoute Delete * TimedRoute Delete * PreTranslator Delete *

Managing the Dial Plan Configuration File 47

When you subsequently import this dial plan, these commands purge any traces of the old dial plan and prevent any conflicts that can result from importing one dial plan on top of an existing one.

You create new entries in the dial plan configuration file by typing in new commands (see “Dial Plan Configuration File Commands” on page 110) or by cutting, pasting, and editing existing lines in the file.

When you cut and paste new lines into dial plan tables, be sure to change the Entry number in the pasted line. If two or more lines have the same Entry number, only the last one takes effect.

Importing and Exporting Dial Plan Configuration Files

You import a dial plan configuration file either to implement changes you have made by editing the file, or to reload a previously saved

configuration.

From the Operations tab of the Dial Plan window, you can:

■ Import a North American Dial Plan ■ Import an International Dial Plan

This section concludes with a discussion of International Dial Plan Issues. When you export the working dial plan, the NBX system constructs a new configuration file from the values in the database and displays it. The new file shows the current date and time. You name the file when you save it. The sample default files include examples of such things as timed routes and pretranslators. To preserve the default (sample) dial plan

configuration included with the system, 3Com advises you to choose a unique file name different than any of the default (sample) dial plan configuration files so that you do not overwrite the sample default files. Import a North American Dial Plan

The default dial plan scheme is as follows:

■ NBX V3000 system — NorthAmerica-4-digit.txt

■ NBX SuperStack 3 NBX system — NorthAmerica-4-digit.txt ■ NBX 100 system — NorthAmerica.txt

Always read the system Release Notes (called readme.txt) for the most up-to-date information on dial plans.

To import a default dial plan configuration file:

1 In the NBX NetSet – Main Menu window, click Dial Plan. The Dial Plan window appears, displaying the Operations tab.

2 Click the Default File radio button. From the Default File pull-down list, select the default file that you want to use.

3 Click Import. 4 Reboot the system.

CAUTION: When you import a dial plan configuration file, the NBX system immediately implements the dial plan. You are always warned that the system may become inoperative. The system becomes inoperative only if you have manually modified a dial plan and have made syntax or content errors. Carefully check any changes that you make to the configuration file before you import.

Import an International Dial Plan

To change the default North American dial plan to a country-specific dial plan:

1 In the NBX NetSet – Main Menu window, click Dial Plan. The Dial Plan window appears, displaying the Operations tab.

2 Click the Default File radio button.

3 In the list next to the Default File button, select the default file that you want to use.

4 Click Import.

CAUTION: When you import a dial plan configuration file, a message warns you that the dial plan may become inoperative. The system becomes inoperative only if you have manually modified a dial plan and have made syntax or content errors. Carefully check any changes that you make to the configuration file before you import.

5 Click Yes. The system imports the new dial plan and produces a report of any errors.

Managing the Dial Plan Configuration File 49

You may see a warning that “destination extension list is empty.” This means that a particular type of device is not installed. You may safely ignore this type of warning.

International Dial Plan Issues

Several international dial plan issues warrant attention. See these topics:

Customizing an International Dial Plan. If there is no customized dial plan for your country, you may need to modify the default dial plan. See “Modifying a Dial Plan Configuration File” on page 54. If you edit the default dial plan, you can test the changes by making a simulated call. See “Testing a Dial Plan” on page 51.

Autodiscovering Internal Telephones. If you autodiscover your company’s internal telephones, Auto Discovery usually begins at number 100 or 1000. However, for some countries, internal telephones begin at a higher number to allow you to directly dial numbers of “national

importance.” Auto Discovery allocates telephone extensions numbers within this range.

■ The default dial plan for the NBX V3000 system allows you to allocate

internal telephones to extension numbers 1000 through 3999.

■ The default dial plan for the SuperStack 3 NBX system allows you to

allocate internal telephones to extension numbers 1000 through 3999.

■ The default dial plan for the NBX 100 allows you to allocate internal

telephones to extension numbers 100 through 449.

For more information on Auto Discovery, see “Using Auto Discovery for Initial System Configuration” in the NBX Installation Guide.

Dialing Outside Lines. To obtain an outside line, dial 9 or 0 as appropriate for your country.

WARNING: You must first obtain an outside line before you can dial emergency numbers.

Importing a User-Defined Dial Plan

To import a customer-defined (user-defined) dial plan configuration file: 1 In the NBX NetSet – Main Menu window, click Dial Plan. The Dial Plan

window appears, displaying the Operations tab.

2 In the User-Defined File box, enter the path and name of the user-defined configuration file, or click Browse to find the file that you want.

The NBX system has no predefined location for dial plan configuration files. You can specify any directory or path that you want.

3 Click Import and reboot the system.

CAUTION: When you import a dial plan configuration file, the NBX system immediately implements the dial plan. You are always warned that the system may become inoperative. The system becomes inoperative only if you have manually modified a dial plan and have made syntax or content errors. Carefully check any changes that you make to the configuration file before you import them.

Exporting (Saving) a Dial Plan Configuration File

When you export (save) the current configuration, the system creates a new dial plan configuration file from the current database. You save the new text file using a name that you choose.

This example refers to Internet Explorer. If you use another browser, you may need to use slightly different procedures.

To export a dial plan configuration file:

1 In the NBX NetSet – Main Menu window, click Dial Plan. The Dial Plan window appears, displaying the Operations tab.

2 Click Export. The system constructs a new configuration file from the current values in the database and displays it. Figure 3 shows a partial display. Scroll your browser window to see your complete dial plan.

Managing the Dial Plan Configuration File 51

3 Click the File menu and select Save As.

4 From the list box at the top of the Save As window, select the destination folder.

5 In the File Name text box, replace the default file name with a new name. The sample default files include examples of such things as timed routes and pretranslators. Verify that you rename the new configuration file with a unique file name so that you do not overwrite the sample default file. 6 Click Save.

Testing a Dial Plan This section describes how to test the currently loaded dial plan by placing a simulated call.

Even if the NBX system is completely installed and operational, a test places a simulated, not an actual call.

Example: If you have an entry in the dial plan for digit sequences starting with 91, with MIN and MAX set to 5, and you test the sequence 9123, the dial plan test reports an insufficient number of digits. However, in actual operation, the NBX system would time out waiting for the fifth digit, and then attempt to place the call. Assuming that the outside line prefix is 9 (such as in the United States), this situation would obtain an outside line (9) and then dial the numbers 123.

You can specify a day of the week and a time by selecting entries from the Day/Time list boxes. This choice instructs the system to act as if the day and time you select are the current day and time.

If you have timed routes defined in the dial plan, you use different day and time settings to determine whether the timed route works properly. Example: Assume that you want a timed route to select route 35 during open business hours Monday through Friday, but route 36 when business is closed on those days and on weekends. After you define the timed route commands and import the modified file, you then test using days and times within business hours (to verify that the system selects route 35) and during closed hours and weekends (to verify that it selects route 36). You can also use day and time settings to test whether the Class of Service settings operate as expected.

Example: You can configure the dial plan to allow toll calls from an extension during open business hours, but to disallow such calls when the business is closed and on weekends. Test using days and times within business hours (to confirm that you can make toll calls from that

extension) and during closed hours and weekends (to confirm that the system prevents such calls).

To create and run a test using the currently loaded dial plan:

1 In the NBX NetSet – Main Menu window, click Dial Plan. The Dial Plan window appears, displaying the Operations tab.

2 Click Test. The TestDial Plan dialog box appears.

3 To set up the simulated call, from the Device to dial from list box, select the number from which you want to dial.

4 In Number to dial, enter the number that you want the system to dial. 5 Select the desired date and time in the Day/Time pull-down lists.

For some tests, the day and time settings are irrelevant. You can leave the settings at their default values (Sunday, 00, and 00).

6 Click Test. The test runs and the results appear in the dialog box. Generating a

Dial Plan Report

This section describes how to create a report containing all dial plan settings, tables, routes, and pretranslators. The report also performs a consistency check to ensure that all dial plan table entries point to valid

Managing the Dial Plan Configuration File 53

routes which, in turn, point to valid extensions. The report also identifies how many devices are using each dial plan table and each pretranslator. Consider these common dial plan problems:

■ Dial plan table entries that point to nonexistent routes

■ Timed route entries that point to nonexistent destination routes ■ Destination route entries that point to nonexistent extensions or

empty extension lists

■ Timed route entries that overlap

■ Devices that do not specify a normal table

■ Devices that point to nonexistent Normal tables, Least Cost Routing

tables, or pretranslators

■ Pretranslator entries that have no operations

If a telephone has no table assigned, that telephone does not have permission to dial. This error is flagged in Reports. If a device has only a Normal table, no error is reported.

If a device has only a Least Cost table, an error is reported. The telephone is still usable and has permissions defined in whatever table has been chosen as Least Cost. If a device has both a Normal and Least Cost table, no error is reported (the usual condition).

When the NBX system detects an error in any line of an imported dial plan configuration file, it ignores that line and continues to process all remaining lines in the file. This precaution minimizes the impact of errors on the dial plan.

To generate a dial plan report:

1 In the NBX NetSet – Main Menu window, click Dial Plan. The Dial Plan window appears, displaying the Operations tab.

2 Click Report. The dial plan report appears. Scroll up and down the browser window to see the full display.

3 Click Close.

The person validating the dial plan test is responsible for verifying that the test call used the correct dial plan table and dial plan table entry.

To record test results and send them to someone, select the text in the results pane and use the browser’s copy function (typically found in the Edit menu) to copy the test results to another application window, such as an editor or e-mail.

Errors can prevent calls from being successfully routed. Warnings are conditions that you can easily correct to successfully route the call. 4 When you are finished, click Close at the bottom of the screen. Modifying a Dial Plan

Configuration File

This section describes how to modify the currently loaded dial plan configuration file.

CAUTION: Modifications must be syntactically correct. Each time that the system imports a dial plan configuration file, it verifies the file for errors and displays the results. To avoid typing mistakes, 3Com suggests that you start with an existing dial plan (for example, one of the default plans that are shipped with the NBX system or a plan from another NBX system), modify it, and save it as a renamed file.

To modify a dial plan configuration file:

1 In the NBX NetSet – Main Menu window, click Dial Plan. The Dial Plan window appears, displaying the Operations tab.

2 Click Modify. The Modify Dial Plan dialog box shows a partial display. Scroll up and down the browser window to see the complete dial plan. 3 Edit the dial plan configuration file. A single line of space is required

between each dial plan entry. You can type a complete dial plan entry anywhere in the file.

4 Click OK. The Import Confirmation dialog box prompts you to confirm the changes.

5 Click Yes. The system imports the modified dial plan. The Dial Plan Consistency dialog box appears, displaying the results of the error and consistency checks.

6 Make a note of any errors, and correct them by editing the file. You may be required to make changes based on warning messages.
