The value of this object indicates the value of the high layer compatibility information element (HLC IE) which must be present in the SETUP call establishment messages received by this basic rate interface (incoming call) when the checking is enabled (see fcfIsdnDSigHighLayerCompatibility) : ccittOsiApplication : the coding standard must be set to 'CCITT standardized coding', the interpretation must be set to 'first (primary only) high layer characteristics identification to be used in the call', the presentation method of protocol profile must be set to 'high layer protocol profile (without specification of attributes)', the high layer characteristics identification must be set to 'OSI application (recommendation X.200 series)', nationalUnknownNetworkedService : the coding standard must be set to 'national standard (only when the desired HLC cannot be represented with the CCITT-standardized coding)', the interpretation must be set to 'first (primary only) high layer characteristics identification to be used in the call', the presentation method of protocol profile must be set to 'high layer protocol profile (without specification of attributes)', the high layer characteristics identification must be set to 'unknown networked service', nationalNotStandardizedApplication : the coding standard must be set to 'national standard (only when the desired HLC cannot be represented with the CCITT-standardized coding)', the interpretation must be set to 'first (primary only) high layer characteristics identification to be used in the call', the presentation method of protocol profile must be set to 'high layer protocol profile (without specification of attributes)', the high layer characteristics identification must be set to 'not standardized application', The default value is 'notTransmittedAndChecked'.
