Configuration and Administration > Devices > Dial Up and Dial Back

Dial Up and Dial Back
The “Dial Up” form allows you to configure the current device for dial-up connection to the network.
The same form is also used to configure the device for dial back. Currently, the “Dial Back” feature only applies to ACS devices. When an ACS unit is configured for dial back, the AlterPath Manager can dial out to the remote ACS unit and authenticate with the ACS. Once authenticated, the ACS drops the line and dials out to a pre-defined number. Simultaneously, the AlterPath Manager sets its modems into a state where it is ready to receive a call. The system allows all remote sites to call back to the same number and support multiple, simultaneous call back connections to the AlterPath Manager.
When the AlterPath Manager receives the dial back call, the authentication is repeated. Upon successful authentication, the system establishes a PPP session and opens the console connection.
Call back connections are included in the log messages.
Note: For dial back to work, you must configure it from the web interface and the CLI.
To Configure Dial Up / Dial Back
To configure Dial Up or Dial Back, follow the steps below:
1.
The system displays the Device Dial Up form.
Device dial up forms vary, depending upon the device being configured for dial up. The following is a device dial up form for a KVM/net.

The following is a device dial up form for an ACS.

Drop-down box to select how you want your PPP connection to be used:
Primary Network - uses a modem connection as the primary way to connect to a device. The connection is dropped when the last user disconnects.
Network Backup - uses a modem connection only if the network connection is unavailable.
If Modem Mode is enabled (either as Primary or Network Backup), then this field is required for PPP connection. Enter the complete PPP phone number to establish PPP connection to a device or console via web interface, CLI, or SSH.
Check box enables ISDN when selected (ISDN modem and connection required). See the “AlterPath Manager Installation, Configuration, and User’s Guide.”
This field (for ACS only) provides a prefix for the remote ACS to use to dial back to the APM. For example, the remote ACS might need to dial a “9” to get an outside line from an office
If this field is blank, the AlterPath Manager IP is used for PPP.
Check box: When selected, PPP Device IP and PPP Local IP are automatically created by the APM (ACS and TS only).
Drop-down box to select the authentication method: “PAP” or “CHAP”
The username of the modem or dialback user (usually the admin user).
The “Set Password” button launches a dialog box in which to enter a password twice (to ensure that the password was entered correctly). This is the password to be used to authenticate the dial back user (usually the admin user’s password).
Check box to enable One Time Password (ACS only). Dialback mode and ISDN must both be disabled for OTP.
The “Set Passphrase” button launches a dialog box in which to enter a password which is used for OTP encryption. You can skip this if you select the “Random Passphrase” check box below this button.
Button to manually reset the OTP. The sequence will be reset upon the next dial up connection or upload.
