Chapter 7 - Callback Security and Remote Configuration
The + and/or - characters entered before the phone number are optional. The + (Deposit
Number) code allows a caller to enter the number he or she wishes the Callback modem to call
back when the caller uses a particular password (Step 3 of Table 7-3). The - character enables
direct entry when the caller uses that correct password (Step 3 of Table 7-3) without the Callback
modem having to return the call.
The ??? entry at the end of the phone number is optional and indicates a subcode number to the
main phone number for that location. The ??? used to dial different extensions at the same basic
number. To use this optional feature, enter the number of ? marks where indicated equal to the
number of digits in the desired extension number, (i.e., with a 4 digit extension enter ????). When
a caller uses that particular password (Step 3 of Table 7-3), he or she then enters an extension
number directly after the password, with the same number of digits as the number of ? marks
originally entered. When calling back that particular number, your modem will also dial the
indicated extension number.
Note: To view Callback Passwords/Numbers, use the L Command.
6. To store changed parameters to memory, enter AT&W0 and hit RETURN.
Note: If you have enabled Callback Security (#DB1 in step 2 of Table 7-2), the modem will be
secured locally. To gain local access, you must again perform steps 7 and 8.
7. Enter your modem's LOGIN Password (as selected in Table 7-1) by entering:
AT#Ixxxxxxxxxx<CR> (xxxxxxxxxx from Table 7-1)
8. Enter your modem's Setup Password (as selected in Table 7-1) by entering:
AT#Syyyyyyyyyy<CR> (yyyyyyyyyy from Table 7-1)
Table 7-3. Callback Operational Sequence Procedures
Perform the following steps when dialing into a dialback modem:
Step Procedure
1. When called, the modem answers and after a slight delay, responds with:
Password>
2. Enter your modem's LOGIN Password (Table 7-1) and hit RETURN. If entered correctly, the
modem responds with:
DB>
3. Enter the Callback Password corresponding to the phone number you wish called back and hit
RETURN (Callback Passwords and phone numbers entered in Table 7-2). You can also use
special characters + and -. They must have been entered as part of the Callback phone numbers
in Step 5 of Table 7-2. If you use the - character along with your password, the Callback modem
will connect directly without hanging-up and calling back. If you use the + character along with
your password, you can also enter a phone number which you wish the Callback modem to dial
after hanging-up. The + and - characters must be entered after the Dial-back password, (i.e.,
DB>xxxxxx+). This is also the point where you enter an extension number if your Callback
number used the ??? feature (Step 5 in Table 7-2).
You have three tries at each prompt to enter the information properly, with an incorrect entry
resulting in a password retry. You must enter the requested information correctly within one
minute or the Callback modem will hang-up. When the information is entered properly, the called
modem will hang-up and after a 15 second delay, call you back. When your modem answers, the
dialback modem will respond with the following:
Password>
4. Enter the modem's LOGIN Password again (the same as in Step 1). The Callback modem
responds with:
CONNECT
You are now in Data Mode.
