6 Callback Security
97
#CBS0 Disables callback security. With this command,
the modem connects as if it did not have callback
security. This command can be entered after the
setup password has been entered.
#CBS1 Enables local and remote callback security. Local
callback security requires that the setup
password be entered to use the AT command
set. The only AT commands that are available
without the setup password are AT, ATI, and
AT#Sx. For the remote callback security
description, see the
#CBS2 description. This
command can be entered after the setup
password has been entered.
#CBS2 Enables remote callback security only. When
remote callback security is enabled, the modem
waits for a call, challenges the remote modem,
calls back the remote modem, and challenges
the remote modem again. Local security is
disabled, allowing calls to be made from the
modem without entering the setup password.
This command can be entered after the setup
password has been entered.
#CBS3 Temporarily disables callback security if either
#CBS1 or #CBS2 is enabled. Callback security
remains disabled until the hangup command
(+++ATH) is executed locally or the modem is
reset. This command can be entered after the
setup password has been entered.
