Testing Features via the Keypad
This feature is only relevant on an S-Bus or U interface. 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.
