Releases

NICC Standards Limited (NICC) has adopted a release scheme for the development of interconnect and interoperability standards relating to NGNs. This release scheme is a mix of both programme management of the NGN standards development in NICC and for interconnect services, defining a set of services that can be supported over a common multi-service interconnect. The release scheme draws together the NICC standards developed for a given NGN service and publishes a comprehensive set of standards for the services in that release in a single step

NICC Releases are controlled by a list for each release. To view the list for a particular release, click the appropriate link below. Each list contains Specification Numbers, Title, Version Numbers applicable to that version and links to the version of the documents for the release.

A full description of the release structure can be found in ND1610.

The NICC Releases are:

Purple Release

The Purple Release includes:-

• Common Transport:- The reference to the specification of a common interconnect transport infrastructure that has the capability to simultaneously support a range of different services.
• PSTN/ISDN Service:- The reference to the specification for interconnecting current PSTN and ISDN services that are on an NGN and the associated use of the underlying common interconnect transport infrastructure. The specification defines the PSTN/ISDN service general connectivity that is used by various interconnecting products (e.g. interconnect for geographic numbers, number portability, carrier pre-selection, etc) but not these specific products themselves
  

Green Release

The Green Release was developed from a set of requirements and includes:-

• Common Transport:- The reference to the specification of a common interconnect transport infrastructure that has the capability to simultaneously support a range of different services.
• Voice Line Control Service: - The service where one Communications Provider will have real time control of the voice application serving individual PSTN access lines provided by another VLA Provider and have access to relevant management functionality. The provision of this technology shall be able to utilise the same physical point of handover as used by the PSTN Emulation service. The architecture shall provide equivalence of both input and output for all parties.
• Common Number Database: - the generic function which holds reference mapping of telephone numbers to Destination Group which is to be used by all UK CPs for call routeing.
• The Purple Release PSTN/ISDN Service. The specification defines the PSTN/ISDN service general connectivity that is used by various interconnecting products (e.g. interconnect for geographic numbers, number portability, carrier pre-selection) but not these specific products themselves.
  

Orange Release

Orange Release is currently under development by NICC. Work areas include support of IMS interconnection, of interconnection using BICC, exchange of presence and location information, provision of location information to emergency services for internet telephony, interconnection to internet telephony and corporate SIP-based networks, expansion of VLC and usage of non-numeric identifiers. The standards will be published on this site when they become available.
