Task

Configure the name of the dialer pool to use for USB modem connectivity—for example, usb-modem-dialer-pool.

J-Web Configuration Editor

1.In the Pool box, type usb-modem-dialer-pool.

2.Click OK.

CLI Configuration Editor

1.Enter

edit unit 0

2.Enter

set dialer-options pool usb-modem-dialer-pool

Configure source and destination IP addresses for the dialer interface—for example, 172.20.10.2 and 172.20.10.1.

NOTE: If you configure multiple dialer interfaces, ensure that the same IP subnet address is not configured on different dialer interfaces. Configuring the same IP subnet address on multiple dialer interfaces can result in inconsistency in the route and packet loss. The router might route packets through another dialer interface with the IP subnet address instead of through the dialer interface to which the USB modem call is mapped.

1.Select Inet under Family, and click Configure.

2.Next to Address, click Add new entry.

3.In the Source box, type

172.20.10.2.

4.In the Destination box, type

172.20.10.1.

5.Click OK.

Enter

set family inet address 172.20.10.2 destination 172.20.10.1

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 Services Router 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 Services Router 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 27 on page 37.
