Configuring Subscriber Accounts

Dialback Access 8-11

Dialback Access

The LX unit supports Dialback as an access method for LX

subscribers. Under Dialback, the subscriber dials in to the LX

unit and logs in as he/she would if he/she were a dialin

subscriber. The LX unit then validates the login and terminates

the call. If the subscriber login is valid, the LX unit calls the

subscriber back. The subscriber is then logged in to the LX unit.

Dialback is used for:

 Security—the destination is recorded by the Telco for billing,

and calls can be restricted to specific destinations.

 Managing connection costs—central site billing.

X To specify Dialback access for a subscriber

1. Specify a dialback number for the subscriber:

Example Subs_jack:0 >>dialback number

19785551978

2. Set the dialback access parameter to

enabled:

Subs_jack:0 >>dialback enable

When a subscriber is configured for Dialback, and

the LX has a Modem Pool, the subscriber can

establish a reverse dial connection from the LX

CLI. (Under reverse dialing, the subscriber is

logged in with his username and password to a

Modem Pool so that the next available modem makes the call

back to the subscriber.)

The dial reverse command is used to establish reverse dial

connections from the LX CLI. The dial reverse command

exists in the User Command Mode and in the Superuser

Command Mode. For more information, see the dial reverse

command in the

LX-Series Commands Reference Guide.

The

dialback

number is

the

telephone

number

that the LX

modem will

dial to call

back the

subscriber.
