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 forbidden calls:
• The modem receives a busy tone after dialing a call, or
• The call is not answered within the time in the Call Timeout (AT
*
TT) option
For these call failure conditions, 11 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.
Belgium—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 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
*

For these call failure conditions, three subsequent redial attempts are allowed. If the
redial call attempts are unsuccessful after a total of four calls, within one hour, the
number is placed on the delayed list. Then it cannot be dialed for 60 minutes. After
60 minutes, the number is available for dialing.
