caller ID
|
Telephone number of the caller on the remote end of a backup
USB modem connection, used to dial in and also to identify the caller.
Multiple caller IDs can be configured on a dialer interface. During
dial-in, the router matches the incoming call's caller ID against
the caller IDs configured on its dialer interfaces. Each dialer interface
accepts calls from only callers whose caller IDs are configured on
it.

dial backup
|
Feature that reestablishes network connectivity through one
or more backup dialer interfaces after a primary interface fails.
When the primary interface is reestablished, the USB modem backup
is disconnected.

dialer interface
|
Logical interface for configuring dialing properties and the
control interface for a backup USB modem connection.
|
|
dialer profile
|
Set of characteristics configured for the USB modem dialer interface.
Dialer profiles allow the configuration of physical interfaces to
be separated from the logical configuration of dialer interfaces required
for USB modem connectivity. This feature also allows physical and
logical interfaces to be bound together dynamically on a per-connection
basis.

|
dial-in
|
Feature that enables Services Routers to receive calls
from the remote end of a backup USB modem connection. The remote end
of the USB modem call might be a service provider, a corporate central
location, or a customer premises equipment (CPE) branch office. All
incoming calls can be verified against caller IDs configured on the
router's dialer interface.
