3. NRIC V Focus Group 4, Interoperability 10/25/2015 Ross Callon 3 Charter The purpose of Focus Group 4 is to provide recommendations to the Council that, when implemented, will facilitate and assure interoperability of public data networks. The duties of the Focus Group 4 will be to prepare studies, reports, and recommendations for assuring data network interoperability within the parameters set forth in the NRIC V Charter. Focus Group 4 will determine what levels of interoperability are needed. Focus Group 4 will also monitor future developments to ensure that interoperability is not at risk. Focus Group 4 will make recommendations with respect to interoperability issues that may arise from convergence and digital packet networks. Focus Group 4 may also make recommendations with respect to such additional interoperability issues as the Commission may specify.

9. NRIC V Focus Group 4, Interoperability 10/25/2015 Ross Callon 9 Cooperation with 2.A2 FG4 previously reviewed Focus Group 2, working group 2.A2, best practices for network reliability in data networks We are intending to review interoperability BPs in the 2.A2 final report

10. NRIC V Focus Group 4, Interoperability 10/25/2015 Ross Callon 10 Testing FG4 has had multiple discussions on testing Agreement: Strong agreement on importance of testing There are many valid forms of testing There are many organizations involved in testing (including vendors and service providers) FG4 is reluctant to endorse any particular test group We have not yet produced formal output in this area. We are proposing that future work of FG4 may include white paper on testing.

11. NRIC V Focus Group 4, Interoperability 10/25/2015 Ross Callon 11 Future Meeting Schedule Nov 13 in San Jose, CA (hosted by Cisco) Intend to discuss possible future FG work If necessary, could consider final edits to white paper on carrier interconnection Additional meetings depend upon NRIC re-chartering Propose to schedule meetings for Jan/Feb, and Mar/April, in anticipation of ongoing work.
