Tokyo
and London, June 3, 2008 - NEC Corporation announced today that
it hasconfigured testing solutions for the construction and operation
phases
of IP networking in response to a growing demand for IP network
architecture from telecom carriers. The solutions have been arranged
into an integrated testing system.
The system consists of the five solutions (listed below), andclassifies
IP network construction into three phases: installation,
network operation and SLA*, with each phase hosting a number of tests
to confirm IP circuit connectivity, network quality and other network
characteristics.
- Installation phase:Testing Solution for System InstallationTesting
Solution for Subscriber Line Activation
- Network Operation phase:Testing Solution for Operation &
Maintenance
Testing Solution for Problem Isolation
- SLA phase:Testing Solution for Services
*SLA (Service Level Agreement): Contract existing between
acommunication service provider and its customers to formally define
service levels.
Testing required in the installation phase of IP network
constructionincludes confirmation of connectivity and verification of
voice/video
communication quality, both at the time of equipment setup as well as
connection to subscriber households. In addition to periodic testing,
service testing and line quality assurance testing, the operation and
maintenance phase requires testing to identify areas of failure in
times of service interruption, as well as confirmation of service
recovery. The tests are complex and highly technical, which has
consequently increased the cost of network operation.
To address these issues, NEC is looking to streamline deployment
andoperation of IP networks and significantly reduce costs by
delivering
carefully crafted solutions that leverage group-wide technological
capabilities and know-how. The new system applies NEC's proven
technology and abundant experience in the field of IP network
architecture, incorporating "NC1900-ST" software to verify the status
of SIP communications and measure communication quality, as well as
"MS3400 Series" software to manage network operations, monitor network
quality and support failure analysis. NEC is actively promoting its
solutions business to telecom carriers.
The features of each solution are outlined below.
1.Testing Solution for System Installation
Provides functions for the
automatic testing of installation works,
including equipment construction and line extensions. A network-based
testing device checks the status of the routing information configured
in the SIP server, making it possible to conduct efficient and
reliable connection testing.
2.Testing Solution for Subscriber Line Activation
Provides testing
functions that facilitate C-plane (SIP) and U-plane
(RTP) conduction and verify quality levels for the opening of
subscriber lines. VoIP-call testing functions confirm signal and
voice quality from a testing device installed in subscriber households,
and can be controlled remotely from an integrated management server
3.Testing Solution for Operation & Maintenance
Provides testing
functions required for such network maintenance tasks
as periodic testing conducted during network operations. The solution
installs such devices as quality control and integrated testing
servers to gather information at regular intervals, and to use this
information to predict and detect the occurrence of service
interruptions or detect silent failures.
4.Testing Solution for Problem Isolation
Provides functions that quickly
and easily locate areas of failure or
quality deterioration during service interruptions. The solution makes
it possible to locate areas of quality deterioration within quality
data and related routing information using estimation engines, as well
as identifies failure zones from the results of End-End connectivity
testing and relay testing.
5.Testing Solution for Services
Provides functions that confirm the
quality of service operations, as
well as tests SLA assessments, SPIT (SPAM over IP Telephony)
countermeasures and service analysis. The solution makes it possible
to determine the quality of individual voice and video services,
measure throughput of Internet services, conduct assessment testing on
user-generated SPIT claims and carry out trend analysis on services.
Furthermore, the anti-SPIT software conducts electronic voice
detection tests to identify undesirable SPIT.
