Computing platforms (i.e., Application Programming Interfaces - APIs) that

17、support such functionally-integrated applications are outside the scope of this Standard.Communication between the computing and switching (i.e., telecommunications) networks may takeplace via intervening networks ranging from simple point-to-point connections to local- or wide-areatelecommunication

18、s networks.This Standard is part of a suite of CSTA Standards and Technical Reports that provide a comprehensivedescription of the architectural and practical issues involved in applying, implementing, and utilizingCSTA-based CTI applications. 2 ConformanceThis Clause specifies the conformance requi

19、rements for a Switching Function, Special ResourceFunction, and a Computing Function.Conformance requirements specify the parts of this Standard that a CSTA conformant implementationshall support.This Standard specifies an operational model (Clause 6, “CSTA Operational Model” and Clause 9,“Generic S

20、ervice Requirements”) that defines a collection of objects (e.g. domains and sub-domains,logical and physical elements, calls) and the relationships between these objects.The behaviours of CSTA-conformant services, features, and event reports are determined by this model.- 2 -2.1 Switching Function

21、In order to conform to this Standard a switching function shall support the following as a minimum:1. the requirements pertaining to CSTA features as specified in Clause 6, “CSTA Operational Model”.2. the requirements as specified in Clause 9, “Generic Service Requirements”.3. the Get Switching Func

22、tion Capability service for all CSTA profiles specified in 2.1.3, “CSTA Profiles”unless otherwise noted in the profile.4. at least one of the Application Association Establishment sequences, including the mandatoryservices specified in the sequence, as specified in Clause 7, “Association Establishme

23、nt”.5. at least one of the profiles as specified in 2.1.3, “CSTA Profiles”.2.1.1 Conformant ServicesIn order to conform to a specific CSTA service an implementation shall support the following as aminimum:1. the requirements of the service as specified by its service description, service request par

24、ameters,service response parameters, and operational model including connection state transitions,monitoring event sequences, and functional requirements.2. the requirements associated with each parameter used in the service as specified by its parameterdescription, format, and functional requiremen

25、ts in Clause 12, “Parameter Types”.3. all of the events that are associated with its service completion criteria, as documented in its eventmonitoring tables.4. service requests that contain a device identifier parameter, an implementation shall support, at aminimum, the Diallable Digits format as s

26、pecified in 10.1.1, “Diallable Digits”. 2.1.2 Conformant EventsIn order to conform to a specific CSTA event an implementation shall support the following as a minimum:1. the requirements of the event as specified by its event description, event parameters, event causes,and functional requirements.2.

27、 the requirements associated with each parameter used in the event as specified by its parameterdescription, format, and functional requirements in Clause 12, “Parameter Types”.3. events that contain a device identifier parameter, an implementation shall support, at a minimum, theSwitching Function
