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.

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
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
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.

Recommendations / Next Steps

• Continue to encourage participation
• Publish informational paper
• Coordinate with other FGs as appropriate
