Configuring Dial-In (Required)

To enable connections to the USB modem from a remote location, you must configure the dialer interfaces set up for USB modem use to accept incoming calls. You can configure a dialer interface to accept all incoming calls or accept only calls from one or more caller IDs.

If the dialer interface is configured to accept only calls from a specific caller ID, the system matches the incoming call's caller ID against the caller IDs configured on its dialer interfaces. If an exact match is not found and the incoming call's caller ID has more digits than the configured caller IDs, the system performs a right-to-left match of the incoming call's caller ID with the configured caller IDs and accepts the incoming call if a match is found. For example, if the incoming call's caller ID is 4085550115 and the caller ID configured on a dialer interface is 5550115, the incoming call is accepted. Each dialer interface accepts calls from only callers whose caller IDs are configured on it.

To configure a dialer interface for dial-in:

  1. Navigate to the top of the configuration hierarchy in either the J-Web or CLI configuration editor.
  2. Perform the configuration tasks described in Table 57.
  3. If you are finished configuring the device, commit the configuration.
  4. To verify that the network interface is configured correctly, see Verifying the USB Modem Configuration.

Table 57: Configuring the Dialer Interface for Dial-In

Task

J-Web Configuration Editor

CLI Configuration Editor

Navigate to the Interfaces level in the configuration hierarchy, and select a dialer interface—for example, dl0.

  1. In the J-Web interface, select Configuration>View and Edit>Edit Configuration.
  2. Next to Interfaces, click Edit.
  3. Next to dl0, click Edit.

From the [edit] hierarchy level, enter

edit interfaces dl0

On logical interface 0 configure the incoming map options for the dialer interface.

  • accept-all—Dialer interface accepts all incoming calls.

    You can configure the accept-all option for only one of the dialer interfaces associated with a USB modem physical interface. The device uses the dialer interface with the accept-all option configured only if the incoming call's caller ID does not match the caller IDs configured on other dialer interfaces.

  • caller—Dialer interface accepts calls from a specific caller ID—for example, 4085550115. You can configure a maximum of 15 caller IDs per dialer interface.

    The same caller ID must not be configured on different dialer interfaces. However, you can configure caller IDs with more or fewer digits on different dialer interfaces. For example, you can configure the caller IDs 14085550115, 4085550115, and 5550115 on different dialer interfaces.
  1. In the Unit section, for logical unit number 0, click Dialer options under Nested Configuration.
  2. Next to Incoming map, click Configure.
  3. From the Caller type menu, select Caller.
  4. Next to Caller, click Add new entry.
  5. In the Caller id box, type 4085550115.
  6. Click OK.
  7. Repeat Steps 4 through 6 for each caller ID to be accepted on the dialer interface.
  1. Enter

    edit unit 0

  2. Enter

    edit dialer-options

  3. Enter

    set incoming-map caller 4085550115

  4. Repeat Step 3 for each caller ID to be accepted on the dialer interface.
