Callback Security
Callback Security causes the responding modem to
disconnect and call back to the phone number provided by
the user at the originating modem. The user enters the
number, when prompted by the remote modem, as a
Directory location 1–10 preceded by the # sign, or as a
complete telephone number (including the pause and wait
dial modifiers). For example:
#1
Directs the remote modem to call back to
the number stored in Directory 1
#10
Directs the remote modem to call back to
the number stored in Directory 10
9W18005551234
Directs the remote modem to dial 9,
wait for dial tone, and call back to
1-800-555-1234
If an invalid directory or telephone number is entered
but the password is correct, the modem will stay online
but will not conduct a callback sequence. The modem also
will not initiate a callback if no directory or telephone
number is specified.
