14.12.1 Testing Features via the Keypad
This feature is only relevant on a S-Bus access. Some network operators do not support
the standard DSS1 features, rather they expect the user to control the network via so-called
keypad command sequences. In these cases, the desired facility is usually activated by
entering a series of characters and then sending these characters within a DSS1-specific
protocol element. These so-called Keypad-Elements are imbedded in a SETUP message.
Each step is acknowledged either acoustically (handset) or via special protocol elements
(cause). These causes are displayed by the ARGUS.
