DELAYED AND FORBIDDEN LISTS
When operating in certain countries, the modem processes call attempt failures as delayed and forbidden calls.
This section describes how delayed/forbidden lists operate in each country that supports this feature.
Australia – Delayed Call Lists
The modem processes call attempt failures as delayed calls, according to PTT regulations. Before
dialing a number, the modem determines whether:
•
The number is on the delayed list
•
The delayed list is full (the list holds 10 numbers)
In either case, the number is not dialed. When the modem is turned off and then on again, the lists are
cleared, and the numbers can be dialed.
After dialing, the modem processes the following call failures as delayed calls:
•
The modem receives a busy tone after dialing a call
•
The call is not answered within the time in the Call Timeout (AT*TT) option
For these call failure conditions, nine subsequent redial attempts are allowed. If the redial call
attempts are unsuccessful after a total of 10 calls, the number is placed on the delayed list. Then it
cannot be dialed for 30 minutes. After 30 minutes, the number is available for dialing.
Austria – Forbidden Call Lists
The modem processes call attempt failures as forbidden calls, according to PTT regulations. Before
dialing a number, the modem determines whether:
•
The number is on the forbidden list
•
The forbidden list is full (the list holds 16 numbers)
In either case, the number is not dialed. When the modem is turned off and then on again, the lists are
cleared, and the numbers can be dialed.
After dialing, the modem processes the following call failures as delayed calls:
•
The modem receives a busy tone after dialing a call
•
The call is not answered within the time in the Call Timeout (AT*TT) option.
For these call failure conditions, three subsequent redial attempts are allowed. If either of the above
call failure conditions occur more than 12 times, the number is placed on the forbidden list, and calls to
this number
are not allowed
