21、gnaling nodes. It represents Network Interconnection Interoperability Forum (NGIIF) consensus arrived at by participating members consisting of Access Service Providers, Access Service Customers and Vendor/Manufacturers. Although aimed at SS7 software, the guidelines are deemed generally applicable

22、to other types of software in use by the Telecommunications Industry. This document does not replace or supersede any existing Contracts, Tariffs or any other legally binding documents. 1.2 Definitions For the purposes of this document the following terms apply: Vendor/Manufacturer refers to those c

23、ompanies that develop and supply software to the Telecommunications industry for switching/signaling node application. Service Provider refers to Access Service Providers and Access Service Customers purchasing software from Vendor/Manufacturers of telecommunications software products. Product: In t

24、he context of this document the term product shall be defined as the “software“ package under development or validation. Service Provider Product requirements: Capabilities as defined by the Service Provider and Industry standards which drive the development of the product. Product Implementation: T

25、he process by which the Service Provider Product requirements are incorporated into a soft-ware product whether or not it currently exists. 1.3 Purpose of Software Validation The purpose of software product validation as described in this document is to provide assurance to all users of software as

26、it applies to the telecommunications industry, that the software products perform according to “agreed upon“ service provider product requirements and that all reasonable care has been taken to identify and correct any anomalies that have the potential to negatively impact the operation of switching

27、/signaling nodes so that the quality of service is continually enhanced to meet or exceed the customers expectations. 2 Basic Premises Service Providers of telecommunications service have an obligation to their Customers to provide the highest standard of error free service. Vendor/Manufacturers of

28、telecommunications switching/signaling node software have a responsibility to the Service Providers of telecommunications services to provide the highest standard of error free software possible. An uncompromised focus on the development/validation of error free software will result in improved qual

29、ity and reliability of the switching/signaling nodes and networks. 6 3 Operating Principles Service Providers should have “agreed upon“ procedures in place with their Vendor/Manufacturers to provide continuous assurance for the quality of software prior to and after deployment in their respective sw

30、itching/signaling networks. When the need for information exchange is identified, such information should be shared in accordance with the guidelines outlined in the Network Interconnection Interoperability Forum (NGIIF) document, titled Information Sharing. For example, signaling anomalies identifi

31、ed in the NGIIF Internetwork Interoperability Test Plan (IITP) testing, or individual software customer problems as they relate to potential non-conformance with industry standards should be shared with the affected Service Provider. Vendor/Manufacturers should review their software development/vali

32、dation processes to continually enhance their capability to identify and fix potential software problems prior to deployment. The Vendor/Manufacturer and their respective Service Provider(s) should utilize knowledge gained during software product testing and deployment phases to augment their testin

33、g procedures, for the purpose of identifying and eliminating potential non-conformance prior to subsequent product to deployment. 4 Criteria for Service Providers and Vendor/Manufacturers In the subsections that follow, this document defines criteria that should be followed by the Service Provider a

34、nd/or Vendor/Manufacturer for software product validation throughout the development process, to achieve the general objectives defined in section 2 of this document. The following subsections are: Service Providers requirements Vendor/Manufacturers requirements Vendor/Manufacturers Implementation V

35、endor/Manufacturers Testing Service Providers Pre-deployment Testing Service Providers Deployment Testing 5 Service Provider (ASP/ASC) Requirements This section defines the responsibilities of the Service Providers in regard to providing their requirements to the Vendor/Manufacturer. 5.1 Written Req

36、uirements Service Providers should provide explicit written requirements for capabilities requested from their Vendor/Manufacturers. Service Providers should ensure that their requirements are clear and complete; these requirements may reference industry standards. Service Providers should define in

37、 writing those standards/requirements that they desire the capabilities to conform to. Specific documents and versions should be identified during the requirements phase. When the standards/requirements specifications used include optional capabilities, the Service Providers should identify in writi

38、ng those options desired. 7 5.2 Standards Interpretations If the Service Provider perceives a standard to be ambiguous, incorrect or flawed, (e.g., open to multiple interpretations), the Service Provider should document their required implementation as early in the requirements phase as possible. In

39、 addition the Service Provider should interface with the appropriate standards body to clarify any ambiguities. The Vendor/Manufacturer should review this information, and provide feedback to the Service Provider during the requirements phase. 5.3 General Network Documentation Service Providers may

40、provide documentation to their Vendor/Manufacturer before the end of the requirements phase describing their network environment. 5.4 Network Uniqueness Documentation This documentation may include any specific test scenarios or situations that may be unique to their network to the Vendor/Manufactur

41、er during the requirements phase. Where requirements are Service Provider specific, the Service Provider shall engage in dialogue with their Vendor/Manufacturer to ensure understanding of those requirements. 6 Vendor/Manufacturer Software Validation Criteria 6.1 Vendor/Manufacturer Requirements The

42、software validation criteria for the requirements are as follows: Known Non-conformance to Requirements - The Vendor/Manufacturer shall provide documentation to the Service Provider identifying all known/anticipated non-conformance(s) to Service Provider Product requirements. For example, a known no

43、n-conformance could exist when a Vendor/Manufacturer only implements a subset of a standard. The Service Provider should review this information, and provide prompt feedback to the Vendor/Manufacturer during the requirements phase. Standards Interpretations - If the Vendor/Manufacturer perceives a s

44、tandard to be ambiguous, incorrect or flawed, (e.g., open to multiple interpretations), the Vendor/Manufacturer should document their planned implementation as early in the requirements phase as possible. In addition the Vendor/Manufacturer should interface with the appropriate standards body for cl

45、arification of any ambiguities. The Service Provider should review this information, and provide feedback to the Vendor/Manufacturer during the requirements phase. Service Provider Changes/Upgrades - All Service Provider requirements including “agreed upon“ changes/upgrades will be documented by the

46、 Vendor/Manufacturer and Service Provider prior to completion of the requirements phase. 7 Vendor/Manufacturer Product Implementation The software validation criteria for Product Implementation are as follows: 8 7.1 Optional Requirements When Service Provider Product requirements include options (e.

47、g., optional parameters or procedures), the Vendor/Manufacturer should provide documentation to the Service Provider identifying which option(s), if any, the Vendor/Manufacturer plans to implement. The Service Provider should review this information, and provide feedback to the Vendor/Manufacturer p

48、roactively. 7.2 Conformance to Requirements The Vendor/Manufacturer should ensure that the software implemented conforms to all specified and “agreed upon“ requirements taking into consideration any documented non-conformance(s) and “agreed upon“ interpretations. The Vendor/Manufacturer shall docume

49、nt all known deviations from Service Provider requirements in regards to capability of the product being implemented. Such information should be provided to the Service Provider at commencement of the software implementation phase and on an ongoing basis. Service Providers should review such information and provide feedback to their Vendor/Manufacturer. 7.3 Cross-product Implementation The Vendor/Manufacturer should ensure that interoperability incompatibilities are not implemented between Switching/Signaling Nodes in their product line. 8 Vendor/Manufactur
