Create a Dial Object
When you create a dial object for a backup interface, it indicates that the interface
can be used as a backup line in a backup pool. It also configures the default
datalink protocol, PPP, for the backup line.
To create a dial object, navigate to the interface prompt and do the following:
1.
Enter the dial object command:
dial
For example, to make serial interface 1/1 a dial object enter:
serial/1/1# dial
This command indicates that the serial interface on slot 5 connector 1 is now
available to be used as a backup line in a backup pool.
For the ARN enter:
modem/1/1# dial
2.
Specify the modem signaling for the dial interface by entering:
media-type
<
type

type can be:
raise-dtr
- A signaling method that enables access to the network by
preprogramming the destination phone numbers into the dial device. Raise
DTR signaling works with any of these interfaces: X.21, V.35, RS-232, and
RS-422.
v25bis
- A signaling method that enables access to the network by passing the
destination phone numbers from the router to the dial device. Using V.25bis,
the dial device can use multiple phone numbers to call multiple destinations.
V.25bis signaling works with any of these interfaces: X.21, V.35, RS-232, and
RS-422.
For v25bis, you need to configure an outgoing phone list (see “C
reating an
Outgoing Phone List” on page 3-17).
hayes
- A signaling method that enables access to the network by passing the
destination phone numbers from the router to the dial device. Hayes signaling
is for asynchronous PPP and works with RS-422 and V.34 interfaces. To use
Hayes as the serial media type, you must also specify a modem initialization
string. The router sends this string to the modem to initiate a call.
