Using the Modem’s Security Feature
Page 14
Enabling Security Callback
The following procedure describes how to enable security callback. To use this feature, you must first
enable the modem’s security feature and then enter Superuser Mode.
1.
Enable security and Superuser Mode if they are not currently enabled (see “Enabling Security” and
“Entering Superuser Mode” on page 11).
Note: To see whether security and Superuser Mode are enabled, type the command AT$D? and
press Enter (for more information, see “Viewing Security Status” on page 17).
2.
Type the command AT$Cn=<telephone number> where:
™ n is a user number from 1 to 20.
™ <telephone number> is the telephone number of the remote modem that your Premier 56
modem is to call back.
Example: AT$C4=9,9495551212 specifies a telephone number of 9,9495551212 to user 4. The
number 9 and comma typically are used when dialing through a PBX (9 accesses an outside line and
the comma pauses the modem before accessing the outside line).
3.
Repeat step 3 for each additional user whose callback number you want to set up (your Premier 56
modem supports up to 20 users).
The Security Callback Process
After your Premier 56 modem is configured for security callback, a remote modem user who calls your
Premier 56 modem sees a CONNECT result code followed by the following prompt:
PLEASE ENTER YOUR PASSWORD===>>
The user at the remote modem provides a user number and a password using the following syntax (for
security, each password character appears as an asterisk):
<user#,password>
For example:
2,zeus
specifies user 2 with a password of zeus.
If the password corresponds to the user number, your Premier 56 modem issues the following message
on the computer attached to it, ends the modem connection automatically, calls back the remote
modem, and establishes a secure connection with it.
