Modem > Advanced

The Modem > Advanced page is used to configure the Remotely Triggered Dial-Out feature, which enables network administrators to remotely initiate a WAN modem connection from a firewall.

Remotely Triggered Dial-Out

The following process describes how a Remotely Triggered Dial-Out call functions:

1.	The network administrator initiates a modem connection to the ADTRAN located at the remote office.

2.	If the ADTRAN is configured to authenticate the incoming call, it prompts the network administrator to enter a password. Once the call is authenticated, the ADTRAN terminates the call.

Note

After three incorrect password attempts, the ADTRAN terminates a Remotely Triggered Dial-out authentication session. Each password attempt is allowed a maximum of 60 seconds. If a dial-out session is terminated, the ADTRAN can be called again for another Remotely Triggered Dial-out authentication session.

3.	The ADTRAN then initiates a modem connection to its dial-up ISP, based on the configured dial profile.

4.	The network administrator accesses the ADTRAN web management interface to perform the required tasks.

Note

If LAN- to-WAN traffic on the ADTRAN generates a dial-out request at the same time as a Remotely Triggered Dial-out session is being authenticated, the Remotely Triggered Dial-out session is terminated and the ADTRAN initiates its own dial-out session.

Configuring Remotely Triggered Dial-Out

Before configuring the Remotely Triggered Dial-Out feature, ensure that your configuration meets the following prerequisites:

•

The dial profile is configured for dial-on-data .

•

The firewall is configured to be managed using HTTPS, so that the device can be accessed remotely.

•

Enter a value in the Enable Max Connection Time (minutes) field. If you do not enter a value in this field, dial-out calls will remain connected indefinitely, and you will have to manually terminate sessions by clicking the Disconnect button.

To configure Remotely Triggered Dial-Out, go the Modem > Advanced screen.

1.	Check the Enable Remotely Triggered Dial-out checkbox.

2.	(Optional) To authenticate the remote call, check the Requires authentication checkbox and enter the password in the Password: and Confirm Password: fields.

Bandwidth Management

The Bandwidth Management section allows the administrator to enable egress (outbound) or ingress (inbound) bandwidth management services on the modem interface.

Note

Bandwidth management is a service and must be registered. To configure the service, navigate to the Application Firewall section of the user interface.

1.	Click the Enable Egress Bandwidth Management checkbox to enable bandwidth management policy enforcement on outbound traffic.

2.	Click the Enable Ingress Bandwidth Management checkbox to enable bandwidth management policy enforcement on inbound traffic.

3.	Select a Compression Multiplier from the drop-down list.

Connection Limit

The Connection Limit section allows the administrator to set a host/node limit on the modem connection. This feature is especially useful for deployments where the modem connection is used as an overflow or in load-balanced situations to avoid over-taxing the connection.

In the Max Hosts field, enter the maximum number of hosts to allow when this interface is connected. The default value is “0”, which allows an unlimited number of nodes.
