12.11.14 Set/Define Dialback
The Dialback feature enables a system manager to set up a dialback list of authorized users for incoming
modem connections. Dialback lists include usernames and corresponding phone numbers. When a
username entered matches one in the list, the port is logged out and the SCS sends the corresponding phone
number to the serial port, at which time the port’s modem profile initiates the modem connection.
Restrictions Requires privileged user status.
Parameters username
A text name, up to 16 characters long. If white space or lowercase characters
are used, the username must be enclosed in quotes.
phonenum
A telephone number.
Note: The ATDT command should not be entered in the telephone number string. The
modem profile will prepend any necessary command prefixes.
Bypass
When the Bypass parameter is associated with a username, the port will not be
logged out, and the user will not be dialed back, when attempting to connect to
the SCS. The word “bypass” must be associated with the username in the
dialback database in order for dialback to be bypassed.
When Bypass is used with the Enabled parameter (that is, not associated with
a username), users not in the dialback database are immediately given the
Local> prompt. When disabled, users not in the database are denied access.
Examples
Local>> SET DIALBACK “susan” 867-5309
