Fostering worldwide interoperability
Overview (1)
TIA believes the subject of “Interoperability” is an
important facet of all of TIA’s standards work.
In our Sector, if we do not have INTEROPERABILTY
we have failed as Standards Developers!
But “Interoperability” is a complex area with many
facets.
A STANDARDIZATION SYSTEM includes not only the
process of the development of the standard, but also
the conformity assessment activities to ensure that
products or systems built to a standard actually
conform to that standard.
However, good standards and conformity
assessment, while necessary for interoperability, are
not in themselves sufficient to ensure
interoperability for many, many reasons.

Overview (2)
Sometimes standards have options or alternatives, so while
built to a standard, and conforming to a standard, if the
correct end-to-end choices are not made, there may not be
interoperability between two standards-conforming
products.
There can be many other reasons why there can be
interoperability issues:
The standard had an error
The product was built with an error -- design error
The standard failed to specify a critical technical parameter
The two implementers interpreted the standard differently
The entity doing the testing for conformity or interoperability
made a mistake in the testing
The specifications for the testing activities had an error in say
test scripts or protocols
The specifications for the testing activities did not specify a
critical parameter necessary for interoperability
The customer made changes after the product was installed
Etc., etc.,

Overview (3)
TIA experiences with Interoperability in the
real world are that the issues affecting
interoperability can be at any layer of the
ISO OSI Seven-Layer Model

Interop Activities at TIA
To demonstrate how Interoperability affects many
areas of standardization at TIA, not just NGN, take
PLEN-05a1, the TIA Standards and Technology Annual
Report (STAR) I mentioned in the TIA PSO report, and
search the PDF for the words “Interoperability” and
“Interoperable,” and you will see that need exists
across TIA technical groups.
In addition, TIA and TIA members have participated in
many external activities concerned with
Interoperability:
For many years TIA and TIA members participated on the FCC’s
NRC/NRIC, which was most recently called “Network Reliability
and INTEROPERABILITY Council” www.nric.org
Now replaced by the “Communications Security, Reliability, and
INTEROPERABILITY Council,” (CSRIC)

Interop Activities at TIA - External
Before it was retired last year, for many years TIA and TIA
members participated on ATIS’s Internetwork
Interoperability Test Coordination (IITC) Committee, and its
Steering Committee.
IITC provided an open forum in which North American telecommunications industry
service providers, vendors, and the user community communicated. This committee
coordinated internetwork, interoperability testing of telecommunications services
and architectures resulting from the introduction of new network interconnections
and technologies
Many TIA members are multi-nationals supporting many
SDOs
ETIS Press Release July 9, 2009, “Plug and Play" interoperability of Gigabit-capable
Passive Optical Networks (GPON) “. . . . confirmed a "plug and play“
interoperability between various vendors' products.”
“The decision to create an OMCI (Optical Network Termination (ONT) Management
and Control Interface) Implementers’ Guide, which is now an ITU-T Standard,
has been for FSAN the key element for the achievement of a full OMCI
interoperability,”
Of 14 vendors listed, 10 are also TIA Members

Strategic Direction
Continue to support interoperability
at TIA

Next Steps/Actions
Continuing cooperation among all PSOs and
groups working on Interoperability
TIA formulating groups are continuing to
develop standards that can be used to promote
interoperability and facilitate interconnection.
This includes contributing to the ITU and global
standards efforts.
TIA will continue to outreach to others to
inform them regarding technologies,
applications, and the standards from TIA
TIA 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

TR-8 Activity and Standards
Subcommittee TR-8.25, Compliance
Assessment, is responsible for standards for
compliance assessment and interoperability
issues.
Within the last year, the subcommittee has
published TIA-102.CABC-A, Project 25
Interoperability Testing for Voice Operation in
Trunked Systems.
In addition, nine documents are in the publication
process

TR-34 Activity and Standards
TR-34.1, Communications and
Interoperability subcommittee, addresses interservice spectrum sharing for achieving
interoperability between satellite systems, as
well as among satellite and terrestrial systems,
networks, and services
