Telecommunications and Internet Protocol Harmonization Over Networks (TIPHON); Numbering; Scenario 1 + Scenario 2
|Publication Date:||1 June 1999|
The present document specifies the naming, numbering, and addressing scheme and related functionality required within TIPHON compliant networks for calls:
- from Internet Protocol (IP) based terminals to terminals in a Switched Circuit Network (SCN) (TIPHON scenario 1); and
- from terminals in an SCN to IP based terminals (TIPHON scenario 2).
The objective of the present document is to ensure satisfactory interworking between TIPHON compliant networks and SCNs. An SCN may be a public network or a private network.
These requirements affect terminal equipment and equipment that performs the roles of gatekeeper and gateway, and the calling procedure for the end user.
Where the text indicates the status of a requirement (i.e. as strict command or prohibition, as authorization leaving freedom, or as a capability or possibility), this may modify the nature of a requirement within a referenced standard used to provide the capability.
