5.6.1
General
Amount of dialled digits to be ignored
In some cases a number is assigned to the tie-line or cross connection the AS55X is
connected to and this number is sent as a prefix to the dialled digits. In such cases, it
is necessary to ignore the digits of this prefix.
At this point, the amount of digits to be ignored can be selected.
Default value:
0
Timeout for autostart / Amount of digits for autostart in international order
An ISDN dialling can be made either en bloc or digit by digit but a GSM call setup can
be made en bloc only. Therefore the AS55X must collect all digits until the dialled
number is complete.
There are four possibilities to indicate the number to be complete:
1st: The ISDN network indicates the completion with a special information
element. This often happens by redialling.
2nd: The calling subscriber indicates the number to be complete with typing a
rhombus (#). This is rarely used in the field, because it is complicated and
sometimes the PBX has problems with this digit.
3rd: A fix amount of digits for dialling to the GSM network can be used. Set this
amount to the maximum number of digits referring to your destination
numbers.
4th: A timeout for waiting for the next dialling digit can be defined. If this timeout
expires, the call-setup to the GSM network will be started immediately.
At the menu item “Timeout for autostart”, the timeout for waiting for the next digit
can be chosen.
Default value:
4.0 seconds
At the menu item “Amount of digits for autostart in international order”, the fix
amount of digits can be chosen. Select the maximum length of the called GSM
number in international form. E.g. for the longest GSM number +491234567890
select 12 digits. This setting does not depend on the really dialled number format in
ISDN. En bloc transferred numbers can be longer than this value.
Default value:
11
