Highlight of Current Activities (1)
 Technical standards development including
contributions to the ITU-T and other global standards
groups
 ATIS’ Next Generation Interconnection Interoperability
Forum (NGIIF) focuses on Next Gen network
interconnection and interoperability
•

•
•
network architecture,
management,
testing,
operations, and
facilitates the exchange of information concerning these
topics.

Highlight of Current Activities (2)
 ATIS’ IPTV Interoperability Forum (IIF)
• Currently working on Use and Test Cases for joint MSF/IIF IPTV
Interoperability test event in Q1/2011
 ATIS’ PTSC Next Generation-Carrier Interconnection (NG-CI) Task
Force
• Phase 1 IP network to network interconnection guidelines have
been completed. These provide physical configuration, protocol
suite profile, operational information to be exchanged between
carriers, and test suites in order to support conformance and
interoperability testing.
• Currently working to complete Phase 2 IP network to network
interconnection guidelines, including defining approaches for
validating these guidelines.
 ATIS’ Emergency Services Interconnection Forum (ESIF)
• Developed Request for Assistance Interface (RFAI) standard (for
transition to Next Gen Emergency Services) and collaborated with
the National Emergency Number Association (NENA) for interop

testing during its Industry Collaboration Event in May 2010.
Strategic Direction
 Since 1984, ATIS has frequently reviewed the range of options to
assess how it could most effectively promote interoperability, e.g.:
• Develop technical standards, and programs to inform industry
about these standards
• Provide guidelines to facilitate interconnection
• Conduct Interoperability tests
• Develop test suites
 The rapid pace of technology development, the desire to promote
innovation and to address user needs responsively have led ATIS to
focus primarily on the development of technical standards and
increasing industry knowledge of these standards
 Complementing this, ATIS provides guidance related to
interconnection (e.g., templates, testing) and occasionally sponsors
targeted testing programs.
• Validates that standards are “interoperable”
4
Strategic Direction
 In parallel with its standards development activities, ATIS provides an
open forum to facilitate discussion and resolution of the operational
and interoperability issues necessary to effectively interconnect
multiple service provider businesses
 The NGIIF, in general, developed guidelines and templates for
interoperability and, where deemed appropriate, testing
 In several very special cases, ATIS has sponsored one-time,
interoperability testing programs to meet targeted, national needs, e.g.
• Stress testing of Signaling System 7
Note: ATIS and its members have played prominent roles in FCC
Advisory Committees on the topics of interoperability and
interconnection.
 With the pace of change and the complexity of user needs and
demands, ATIS will continue to actively evaluate how to best address
interoperability.

Challenges
 Standards processes, while promoting interoperability, should also foster
innovation, competition and infrastructure development that address user
needs on a timely and cost-effective basis.
 The inclusion of options, ambiguities, etc., in standards make
interoperability more difficult, but reflect the realities of consensusdevelopment and the need for users to decide what features and
capabilities meet their needs.
 Compliance with technical standards does not guarantee interoperability.
 Innovations in user applications and in network capabilities to support them
are driving the development of standards.
 These challenges can be mitigated through interop “profiles” backed by
detailed test specifications for the profile
• IIF Test specs
• PTSC NG-CI guidelines
6
Next Steps/Actions
 ATIS groups are continuing to develop standards that can be used to
promote interoperability and facilitate interconnection negotiations. This
includes contributing to the ITU and global standards efforts.
 ATIS will continue to outreach to others to inform them regarding
technologies, applications and their standards.
 ATIS will continue to partner with other PSOs and the ITU on efforts
that effectively promote interoperability, innovation, competition, and
cost-effective infrastructure deployment to address market needs on a
timely basis.
 As it has in the past, where appropriate, ATIS will host specific
interoperability testing programs that address targeted industry needs
(e.g., MSF/IIF IPTV Interop Event).

Proposed Resolution
 No changes proposed to existing Resolution
(GSC-14/28) at this time.

Additional Current Activities (1)
 Technical standards development including
contributions to the ITU-T and other global
standards groups:
• ATIS’ Packet Technologies and Systems
Committee (PTSC)
• ATIS’ Network Performance Reliability and
Quality of Service Committee (PRQC)
• ATIS’ Telecom Management and Operations
Committee (TMOC)
• ATIS’ IPTV Interoperability Forum (IIF)
• ATIS’ 3GPP effort
10
Additional Current Activities (2)
 ATIS members continue to work with colleagues around
the world to progress NGN interoperability through the
development of interface and performance standards
including in the ITU-T and 3GPP.
 The focus is on specifications on topics such as:
•
•
•
•
•
•
•
•
Services
Architecture
Signaling
Quality of Service
Security
Network Management
Emergency Communications
Identity Management
11
Additional Current Activities (3)
 ATIS’ Next Generation Interconnection Interoperability
Forum (NGIIF)
• addresses next-generation network interconnection and
interoperability issues associated with emerging
technologies. Specifically, it develops operational procedures
which involve the network aspects of architecture, disaster
preparedness, installation, maintenance, management,
reliability, routing, security, and testing between network
operators.
• addresses issues which impact the interconnection of existing
and next generation networks and facilitate the transition to
emerging technologies.
12
Additional Current Activities (4)
 ATIS’ IPTV Interoperability Forum (IIF) Testing and
Interoperability Committee
• develops the necessary test scripting and test planning for
the interoperability of ATIS IIF standards and addresses
IPTV interoperability issues, providing recommended
courses of action for mitigation of the identified issues.
13
Additional Current Activities (5)
 PTSC Next Generation-Carrier Interconnection (NGCI) Task Force
• Mission - develop an IP network to network interconnection
guideline that will provide physical configuration, protocol
suite profile, operational information to be exchanged
between carriers, and test suites in order to support
conformance and interoperability testing.
• Scope - A testing environment and tests will be defined that
can be used to perform interoperability testing of various
services between two carriers. Initial focus of the NG-CI TF
will be voice and VoIP services Interconnection over IPbased links/networks.
