Brix Networks Chooses Ditech Networks' EXi Technology to Complement Service
Assurance Solutions
Brix Is The Latest Organization To Become Part Of Ditech's EXi Everywhere
Partner Program

LAS VEGAS, March 31 /PRNewswire-FirstCall/ -- Ditech Networks (Nasdaq:
DITC), a leading provider of voice quality solutions to the world's
communications industry, today announced, at CTIA Wireless 2008, that Brix
Networks, a global provider of open and extensible converged service assurance
solutions, will integrate Ditech's voice quality measurement technology into
its products that manage and monitor the quality of VoIP networks. Brix is the
latest organization to become part of Ditech's EXi Everywhere Partner Program,
which makes Ditech's voice quality measurement technology available to the
communications industry.
Brix will integrate Ditech's Experience Intelligence (EXi) technology into
its BrixCall advanced call signaling analysis and media correlation
application. Brix products gather intelligence from network elements and
endpoint devices to create a comprehensive view of performance and quality for
revenue-generating services. The addition of EXi enables Brix to extend these
capabilities to provide a view of how the subscriber call experience is
impacted by a variety of voice quality impairments, such as background noise,
echo, and mismatched speech levels.
Separately, Brix also announced today that it will integrate EXi
technology into the company's BrixCall application.
"Brix Networks is aggressively leading the effort to promulgate an open,
standards-based approach to service assurance," said John Burnham, vice
president of marketing at Brix Networks. "Making EXi and the accurate
measurement of voice quality broadly available to the communications industry
fits well with this goal."
EXi has been used to measure real-time voice quality in both TDM and IP
networks. EXi quantifies the impact of voice quality impairments caused by the
places where people make calls, codec impairments, packet loss, and by the
wide variety of mobile devices like phones and headsets. However, unlike many
network test solutions that focus on measuring network transmission quality,
EXi is fully capable of measuring and scoring the actual speech quality
experienced by subscribers in real-time, on every call in a network. Carriers
can use this information, along with information from other systems, to
identify and address the impact of substandard voice quality on churn,
customer satisfaction, subscriber additions, marketing programs and network
design.
EXi has been utilized in the industry as a complement to existing test and
measurement solutions. Brix products will be able to capture voice quality
impairments that originate from the subscriber's environment, and add that
view to impairments originating in the network, to provide its customers a
comprehensive picture of actual voice quality that is experienced by
subscribers. Information from EXi about signal, noise, echo and packet loss
can be input into the ITU G.107 E Model, which fits well with Brix's
commitment to open standards.
"Brix Networks has a long-standing commitment to standards and the
delivery of open solutions to its customers," said Karl Brown, vice president
of marketing at Ditech Networks. "As part of Ditech's EXi Everywhere Partner
Program, Brix can bring to its customers an important aspect of voice quality
that can help shape a service provider's understanding of their voice
service."
Ditech's EXi Everywhere Partner Program makes the company's EXi technology
available to the communications industry. In addition to deploying EXi on its
own voice quality platforms, Ditech is making multi-platform support available
as part of its EXi Everywhere Partner Program, including mobile handset and
headset manufacturers, communications providers, network equipment vendors,
test and measurement companies, standards organizations, consulting firms and
other solutions providers.
