Interoperability and Conformity Assessment
Partial missing of vendor’s committed implemented
functionalities affects general quality of services
 No separate organization or office responsible to verify and assess the
quality and functionality pre-declared by vendors
 Telcos don’t have sufficient experience in verifying quality and capacity
of the systems as well as a standard Test Lab to conduct the testing and
conformity assessment of the equipment’s quality
Affect the quality of service delivered to customers
Ex:
• It was not possible to implement vendor H’s EMR function in V’s
mobile wireless network.
• In transmission network, vendor H’s SDH equipment Metro 100 lacks of
LCAS function
Interoperability and Conformity Assessment
(Cont)
Partial lack of interoperability between equipment of
same or different manufacturers results in the
impossibility to access to services
 ITU recommendations and 3GPP specifications may have many
optional features and parameters but vendors sometimes choose only
some but not all those optional features and parameters
Incompatibility of equipments from different suppliers
Ex:
• For EoS service (Ethernet over SDH), equipments of many suppliers
can not be configured inter-networking (in fact, in telco V’s case,
equipments of supplier E, H, Z could not be inter-networking
configured)
Interoperability and Conformity Assessment
(Cont)
Need to apply unexpected procedures to obtain that
functionalities work
 lack of ITU recommendations to map in while the development of new
end-user equipments and network equipments is getting more and
more diversified
Telco has to look for another standard body or forum to refer to
Ex:
• For NGN network that provides VoIP and multimedia services, there
are many types of end-user equipments such as ATA, HomeGateway
and IP phones but it is not true that every terminal will be compatible
with the existing NGN that Telco has already invested using
equipments from one supplier
Interoperability and Conformity Assessment
(Cont)
Equipment lack of conformity with standards
 Most of equipments supplied by vendors to build the
network are declared to be compliant to international
standards but there are not concrete proofs or clear
binding.
Mandatory and optional terms are applied in different way for
each operator/telco or supplier. Optional features can affect
connections and interoperability between equipments and
quality of service.
Proposals
• ITU should open a channel to assist telcos to solve all mentioned
problems.
• Viet Nam call for ITU’s assistance and sponsoring for training and
building a standard Lab for assessing and testing quality and capacity
of telecom network equipments (not only terminal equipments)
from suppliers.
• ITU should help telcos and request vendors to cooperate with telcos
in dealing with non-interoperability.
• ITU would produce guidelines for developing countries in applying
ITU recommendations and build our own national standard system
for NGN/IP/3G in which specifications and parameters are chosen
suitable with the conditions of Viet Nam as well as other countries in
the region.
• ITU should consider holding the workshop on the administrative role
in conformity assessment including best practice and experience of
developed countries in this issue.
