Highlight of Current Activities
• ATIS’ Packet Technologies and Systems
Committee (PTSC)
– Currently working to complete Phase 2 IP networkto-network interconnection (NNI) guidelines,
including defining approaches for validating these
guidelines.
– Developed a technical report (ATIS-1000053) that
specifies the protocol profile, test suites and
questionnaire for supporting Emergency
Telecommunication Service (ETS) on IP-based
NNIs.
• Testing occurred in January 2013.
• Results are being examined to determine if any
modifications are necessary to ATIS deliverables.

Highlight of Current Activities
• ATIS’ Cloud Services Forum (CSF)
– Significant value was realized from interoperability and
interconnection testing of unified visual communications in the
cloud in 1Q 2013.
• Although inter-provider interoperability testing has occurred in
the past, this is the most comprehensive testing across an NNI
between two providers to date.
• Initial findings are key to accelerate and extend incremental
system-to-system testing.
• Opportunity to build on success of interworking of multiple
providers/vendors by expanding participation.
• Proven results lead to broader adoption of IP services and
promotion of IP-based interconnections.
• Plans are underway to expand on findings to standardize
service interconnect.

Highlight of Current Activities
• ATIS’ Next Generation Interconnection
Interoperability Forum (NGIIF)
– Led a major effort to find solutions to challenges rural
consumers and businesses faced in receiving long
distance calls.
• Included participation from American rural telecommunications
associations, rural carriers, major national service providers,
state-level regulators, and the FCC.
– Resulted in the publication of the ATIS Intercarrier Call
Completion/Call Termination Handbook, which provides
best practices for carriers to troubleshoot call termination
issues.
– ATIS currently participating in a joint national call
completion task force to create a nationwide end-to-end
test using pre-existing test tones.

Highlight of Current Activities
• ATIS’ Device Solutions Activities
– Open Real-Time Communications API (ORCA)
• Open source project in support of WebRTC-enabled
browsers
• Software (javascript) was generated first; any needed
standards work will follow
• Other device-facing projects will follow
– ATIS Device Solutions Initiative (DSI)
• ORCA is the first project being launched under DSI
• Comprised of companies that want to influence direction of
ORCA and how networks will evolve in support of edge
devices
• Objective is enhanced value (increased service provider
revenue) through new “network-enabled” services

Strategic Direction
• ATIS will continue to promote interoperability via:
– Developing technical standards, and programs to inform
industry about these standards
– Providing guidelines to facilitate interconnection
– Conducting interoperability tests
– Developing test suites
• Work with members to ensure:
– Device/Network interoperability (e.g., via ORCA)
– Network/Network interoperability (e.g., via Content Delivery
Network Interconnection)
– Network/Service interoperability (e.g., via Telepresence, Text to
9-1-1, Commercial Mobile Alert System)

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.
• ATIS and its members have played, and will continue to play,
a prominent role 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, including:
– Device Integrity
– Cyber Security
– Software Defined Networks

Challenges
• Companies that are first to market often become “the standard.”
– Consider Apple HTTP Live Streaming, which was developed
outside of the typical standards process by a single company, and
subsequently was distributed to the IETF for comments.
• 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.

Next Steps/Actions
• ATIS is continuing to develop needed standards and
solutions, but are using market-driven techniques to do
so.
• ATIS will continue to reach out 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.

Additional Current Activities
• 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

Additional Current Activities
• 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.

Additional Current Activities
• ATIS’ PTSC IP Interconnection (IPI) Subcommittee
– Similar to Circuit Switched networks, IP networks will interconnect
using Network-to-Network Interfaces. In addition, IP networks will
communicate with 3rd party Service Providers via either Applicationto-Network Interfaces (ANIs) or Service-to-Network Interfaces
(SNIs). The difference between ANI and SNI is that the SNI allows
for the passage of media (e.g., content delivery, Interactive Voice
Response (IVR)) in addition to signaling. In addition, there are User
Network Interface (UNI) and other reference points in the ATIS
architecture that will need to be validated.
– The PTSC IPI will lead and coordinate with other committees where
appropriate on the following tasks:
• Define Standard Protocol Profiles for the NNI, ANI, SNI, UNI and other
reference points.
• Define Interconnection Guidelines.
• Define Interoperability Test Suites.

Additional Current Activities
• ATIS’ Cloud Services Forum (CSF)
– Promotes the integration of cloud technologies and network
infrastructure to realize the significant benefits of cloud, by:
• Developing standards to enable the network to do more than it does
today (e.g., expanding product offerings including services on demand,
accelerating time-to-market, lowering costs, minimizing complexity,
increasing scalability);
• Focusing on the creation of reusable Service Enablers to progress each
phase of work; and
• Creating technical solutions in support of a global marketplace to help
Service Providers realize cloud’s full potential.
