COMSPHERE 392xPlus Modems

DTE-Side Passwords

DTE-side password entry requires the originating user to supply a valid password via the DTE.
This method of password entry occurs after the modems' training sequence, but before normal
connection. The modems must be configured for asynchronous operation to use this type of
security.
When using DTE-side password entry, the modems go through their normal training and error
control negotiation. Once complete, the answering modem requests a valid password from the
originating user. The originating user must enter, via the DTE, a password that can consist of digits
and case-insensitive letters. Note that DTE passwords can be from 1 to 6 characters in length. The
answering modem verifies the password against its password database table, and if valid,
completes the data connection, thus allowing DTE data to be passed. As with VF-side password
entry, the answering modem must be a 392xPlus modem and the originating modem can be either
a 392xPlus modem or any vendor's modem.
The following example illustrates the format of DTE-side password:

Combination of VF-Side and DTE-Side Passwords

The previously described methods of password entry can be combined to provide two layers of
security. In this case, the modems negotiate VF-side password entry prior to training. If successful,
the modems connect and then prompt the originating user for a valid password. If correctly
entered, the modems connect.
