The intention is to provide support for the following classes of devices connected to a 5G-RG:
The project will be performed in phases:
1) A study period whereby the aspects of GSMA NG.114 that are required by operators for PSTN simulation are identified as well as features not covered in NG.114, as well as what CODECs are required to be supported. The study would include such considerations as operator requirements and regulatory obligations, voice quality, security etc. An additional objective would be determine if existing feature sets can be reduced to eliminate support for obsolete features. At the end of the study period a document plan will be established for the specification work. This may be one or more TRs or one or more separate voice modules as a further amendment to TR-124 is created.
2) A specification period.
3) Extensions to the CWMP/USP data model.
Testing and interoperability could be future considerations
What will not be in scope (at least initially) will be: ISDN BRI and PRI support
Define a profile of 5G-RG behavior to support PSTN simulation in the context of voice in the 5G System
The primary motivation is the savings that can be achieved by convergence onto the mobile voice system, and voice quality improvements achievable by the use of contemporary CODECs. This is as opposed to the status quo whereby operators maintain two systems for voice with the attendant overhead.
Shifting wireline PSTN emulation to align with how voice is delivered in the 5G system would drive convergence and hence savings in a number of areas:

Meeting / Conference Call Calendar
(Note: Contribution deadline is the preceding Monday COB )
Technical: THU 7AM PAC 2hs
1st hour: 5G PS, 2nd hour: IMS for 5G-RG PS
Marketing: THU 8AM PAC 1h
For meeting & conference call agendas and minutes please refer to the PS wiki child pages.
We make use of collaborative tools, i.e. the BBF JIRA (CONTRIB project) and wiki
Contributors are encouraged to use JIRA to make contributions:
In addtion, contributions can be made:
We will preferably handle new contributions on the bi-weekly conference call series, but they can also be discussed via email (and via f2f meetings)
For conference calls, the contribution upload deadline is three business days prior to the call (i.e. Monday COB, for the current series).
Editors update the document baseline(s) according to agreements (documented in meeting minutes or on the mailing list), i.e. incorporate contributions. For additional information please refer to editor guidelines.
