Click OK.
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.
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.
