3.If you are finished configuring the router, commit the configuration.

4.To verify that the network interface is configured correctly, see “Verifying the USB Modem Configuration” on page 42.

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-alloption for only one of the dialer interfaces associated with a USB modem physical interface. The router uses the dialer interface with the accept-alloption 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.

Configuring CHAP on Dialer Interfaces (Optional)

You can optionally configure dialer interfaces to support the PPP Challenge Handshake Authentication Protocol (CHAP). When you enable CHAP on a dialer interface, the Services Router can authenticate the remote locations connecting to the USB modem.

For more information about CHAP, see the J-series Services Router Basic LAN and

WAN Access Configuration Guide and the JUNOS Network Interfaces Configuration

Guide.
