COURIER HIGH SPEED MODEMS
Dial Security D-3
If the password is valid, a secure connection is completed.
If the password is invalid, the host modem prompts twice more
before disconnecting.
If there are no password attempts at the remote end, the host
modem times out after 60 seconds and disconnects.
NOTE: There is no prompting capability in synchronous mode.
Prompting is more flexible than autopass because it:
• doesn't require a remote modem to have U.S. Robotics
Dial Security.
• doesn't require a V.42 connection, so remote modems
without V.42 error control capabilities can connect.
Optional Dialback
Dialback offers an additional layer of security. When the host
modem receives a valid password that matches an account and
Dialback is enabled, the host first disconnects. The remote user
receives a NO CARRIER message. Then the host modem dials
back the remote modem.
Typically, the Dialback number is stored in the Security
account’s phone number field. However, if the security account
has been set up to allow a new number, the host prompts the
remote user for the new number before hanging up, and then
dials back.
In order to use dialback, Dial security and prompting must be
enabled.
