
Operation mode / Fax call prefix
There are two ways to use a fax machine with the WLL550 Pro, First you can attach
your phone and fax directly to its dedicated connectors. The second way is to attach
the WLL550 Pro to an analogue PBX or a Phone/Fax combo. In default mode all
incoming faxes and calls will be directed to different POTS ports. In ‘trunk mode’ all
calls are directed to the phone connector. To separate outgoing fax calls from voice
calls in ‘trunk mode’, you have to dial a fax prefix (e.g. *8 004944130005…) for each
fax. This prefix (*8) is not a part of the called number will be deleted by the
WLL 550 Pro.
Default value: Phone and FAX at different interfaces
Default value: not reported

Timeout for autostart / Amount of digits for autostart in international order
At POTS interfaces dialling can be made only 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 two ways to indicate the number to be complete:
1st: Define a fix amount of digits for dialling to the GSM network. Set this amount
to the maximum number of digits referring to your destination numbers.
2nd: Define a timeout for waiting for the next digit. After 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 numbers in
international form. E.g. for the longest dial 491234567890 select 12 digits.
If you are not sure about the maximum lengths of the number set this value to higher
than 15.
Default value: 21
