DEFINED AS "This object identifies characteristics of the Access Port Profile ISDN object class to be instantiated for screening as defined in Calling Line Supplementary Service I.251.3.
The attributes included in this object provide an interface with the capability of defining the set of Calling Party Valid Directory Numbers and a Calling Party Default Directory Number for the interface. It also provides a boolean attribute whose value determines whether or not calling party number screening is to be used by call originations.
The following table shows the possible combinations of the attributes for Calling Party Number Provision Necessary (CPNPN)VR, Screening of Calling Party Number (SCPN)VR, Calling Party Number Discard Control (CPNDC)VR, and Calling Party Default Directory Number (CPDDN)VR.
CPNPN indicates whether the calling party number must be provided by the calling user for call originations. If CPNPN is Y, then all call originations from the interface must provide a valid calling party number.
SCPN indicates whether calling party numbers received from the interface for call originations will be screened against the list of valid DNs for the interface.
CPNDC indicates whether failed-screening and not-screened calling party numbers are discarded from the calling information. If CPNDC is Y, then calling party numbers that are either not screened or fail screening are discarded.
CPDDN is the default DN (or DNs/bearer) that are used for call originations from this interface where the user does not provide a valid calling party number.
The scenario represented by the first row requires that the user provide valid calling party numbers (CPNPN = Y) for all call set-ups from the interface. User-provided calling party numbers will be screened for validity (SCPN = Y). If the calling party number fails screening, then it is discarded (in fact, the whole call is discarded so CPNDC really has a different meaning in this case). If the calling party number is not provided by the user then the call is cleared. CPDDN is not applicable in this scenario since the DN for the call must come from the user.

The second row represents a scenario where the user does not have to include the calling party number (CPNPN = N) for call set-ups from the interface. If the calling party number is provided by the user, it is not screened (SCPN = N) and it is not discarded (CPNDC = N). Any user-provided calling party number is passed as part of the call and may be delivered to the called party if the called party supports two-number delivery. CPDDN is required, and in fact, the default DN is used for every call origination from the interface.
The third row represents a scenario where the user does not have to include the calling party number (CPNPN = N) for call set-ups from the interface. If the calling party number is provided, it is not screened (SCPN = N) and discarded (CPNDC = Y). CPDDN is required, and in fact, the default DN is used for every call origination from the interface. Any user-provided calling party numbers are ignored (not screened and discarded).
The fourth row represents a scenario where the user does not have to include the calling party number (CPNPN = N) for call set-ups from the interface. If the calling party number is provided it will be screened for validity (SCPN = Y). If the user-provided calling party number passes screening then that DN is used for the call. CPDDN is required, and the default DN is used for call originations from the interface when the user-provided calling party number fails screening, or if the user does not provide a calling party number. Any user-provided calling party numbers that fail screening are also passed as part of the call (CPNDC = N) and may be delivered to the called party if the called party supports two-number delivery.
The fifth row represents a scenario where the user does not have to include the calling party number (CPNPN = N) for call set-ups from the interface. If the calling party number is provided it will be screened for validity (SCPN = Y). If the user-provided calling party number passes screening then that DN is used for the call. CPDDN is required, and the default DN is used for call originations from the interface when the user-provided calling party number fails screening, or if the user does not provide a calling party number. Any user-provided calling party numbers that fail screening are discarded (CPNDC = Y).";;
