The IP-NNI Initiative
In December 2013, the Alliance for Telecommunications Industry
Solutions (ATIS) and the SIP Forum launched a joint task force
to develop detailed specification of IP-NNI (Network-to-Network
Interface) for all North American Service Providers.
•
ATIS is a global standards development organization that develops
technical and operations standards for information, entertainment,
and communications technologies.
•
ATIS’ Packet Technology and Systems Committee (PTSC) develops
standards and technical reports related to services, architectures,
and signaling, including IP Interconnection.

How did this get started
•
Last Fall The SIP Forum and ATIS were approached by several
service providers to see if there was some way to cooperate
•
It was self evident that the Business Case for an implementable SIP
Profile of the NNI was imperative and necessary.
•
•
First the Cable, then SIP Trunking, now VoLTE
Passing Excel Spreadsheets via E-Mail will not scale
•
ATIS represents a very significant part of the Telecom industry, so
does the SIP Forum.
•
Joint agreement on a “open multi-stakeholder consensus driven
process” that any engineer in the industry could participate in.
•
The result is broad industry participation (125+) from wireline
providers (LECs, cable and broadband), wireless providers, and
vendors. All output will be freely distributed.

IP-NNI Initiative in 2 Parts
•
PROTOCOL: A Profile of SIP that addresses how SIP works “on the wire”
based on actual deployment experience.
•
•
•
•
ROUTING : Agree to methodology to translate E.164 numbers for SIP
routing data.
•
•
Similar to what the SIF Forum has done with PBX to Carrier in SIP Connect 1.1
Every instance of IP interconnection is currently a one-off, requiring a detailed
engineering analysis and often involving “protocol normalization” between
carriers. This is a huge OPEX problem.
SIP is complicated its not one comprehensive standard its 250+ with varying
interpretations.
What is the role of the Numbering Databases [LERG/NPAC] and what data
elements need to be exchanged. ENUM?
The initiative is co-lead by:
•
Martin Dolly, AT&T
•
Chris Wendt, Comcast
•
John Barnhill, GENBAND

•
The Regulators are being briefed.
•
The initiative must support key public policy principles:
•
•
•
•
•
Universal connectivity to next generation broadband networks
and services.
The protection of consumers, including safeguards against
fraudulent, deceptive and unfair business practices;
Uninterrupted, seamless access to public safety, national
security, emergency preparedness/response services;
Continued network reliability and robustness
