Ring signal frequency selection
Here supports four types of ring signal frequency, 20Hz, 25Hz, 30Hz & 50 Hz. User
can choose a proper ring signal frequency according to the ring frequency of the
phone user adopts.
Usually the ring signal frequency adopted in the U.S.A. is 20Hz.
The ring signal frequency in Europe is 25Hz.
The ring signal frequency adopted by the major countries in the world ranges from 20
to 50Hz.
The default setting is 25Hz.
International busy tone setting
User can choose the living country from country selection list to get the familiar busy
tone. When user can’t find the living country from the list, user can configure the busy
tone parameters themselves if they know the appropriate setting. Then click OK. It is
not necessary for user to change this setting for general application. However, user
needs to set proper busy tone if user wants to use Call Forward function, otherwise
there would be forwarding call non-disconnection problem even the caller has hung
up the initial call.
This feature also allows user to set the appropriate settings of busy tone when
ST-1002 is connected with one PBX for different application. By selecting a country,
the device will activate the specific busy tone frequency and cycle adopted by local
Public Switched Telephone Networks in that country. Sometimes, the connecting
PBX doesn't have the exact busy tone parameter as defined in user's country. For
this case, user might encounter busy tone detection and unfamiliar busy tone
problems even selecting user's country. User can configure the busy tone
parameters themselves if they know the appropriate setting. Enable user's busy tone
parameter setting option as below figure and fill in appropriate parameters, then click
OK. The parameter will be saved and active.
The default international busy tone country setting is decided by the “Select Setup
Language” selection when ST-1002 is installed. For example, when user selects
English, the default country will be United Kingdom. ST-1002 supports busy tone for
23 countries now.
