COMSPHERE 3821Plus Modem

VF Passwords

VF passwords consist of DTMF tones and are entered by the originating caller using the AT Dial (D) command, or the keypad of an attached telephone. They must consist of eight decimal digits, 0 through 9, and are terminated with the # symbol. For example, if 11223344 is a valid VF password on the 3821Plus modem at the telephone number 555-4321, it can be accessed with this command:

ATDT555-4321@11223344#

If pulse dialing must be used, the VF password must still be sent in DTMF tones. This can be done using a combination of P (pulse) and T (tone) dial modifiers:

ATDP555-4321TW11223344#

The requirement of the @ (wait for quiet answer) or W (wait for second dial tone) dial modifier depends on the VF_Prompt_Type selected in the Security configuration options group of the Configure branch. For more information about dial modifiers, see the Dial (Dn) command.

DTE Passwords

DTE passwords are entered by the originating caller from the DTE keyboard. They may consist of six characters, and may be a combination of decimal digits 0 through 9 and the letters A through Z (uppercase or lowercase).

Up to 3,000 VF and DTE passwords can be stored in the password table in the memory of the 3821Plus modem. Each password is indexed by a number, 0001 through 3000. The index number is used when displaying or changing a password.

Originate Security

An Originate Access password is entered by a local user to gain access to a local 3821Plus modem. This password must be embedded in the AT dial command. The password must be defined as a DTE_Entry type in the password table.

The following example describes how to enter an Originate Access security password:

TYPE: ATD%C2C3D2%T18135551234

Where: ATD is the AT dial command.

%is the start and stop dial string command interrupt characters; the Originate Access password must be enclosed by these characters.

C2C3D2 is the alphanumeric 6-character Originate Access password on the local modem.

T is the Tone (DTMF) dial modifier.

18135551234 is the phone number of a remote modem.

PRESS: Enter

Answer Security

DTE passwords alone, or a combination of both VF and DTE passwords, may be used for Answer Security.

With VF and DTE Security, modems negotiate VF password entry before training. If successful, the modems connect and then prompt the user for a valid DTE password.

Another combination is called VF with DTE Security. In this case, the modem will accept as valid only the DTE password whose password table entry immediately follows that of the VF password that was received. For example, if the VF password at index number 9 is used to connect, the DTE password at index number 10 is the only valid DTE password.

The Password Type option of the EditPassWdTable group determines whether VF and DTE Security or VF with DTE Security is used.
