Ditech Communications Announces General Availability of New Voice
Processing Systems which Enable Low-Cost Capacity Expansion for
Mobile Operators New Quad Voice Processor (QVP) Systems Focus on
Capacity Enhancement and Improved Voice Quality for Mobile Networks
MOUNTAIN VIEW, Calif., April 21 /PRNewswire-FirstCall/ -- Ditech
Communications Corporation, a leader in the development of voice
processing systems for communications networks, today announced
general availability of its new Quad Voice Processor(TM) (QVP(TM))
systems, a full line of advanced voice processors for mobile
networks. Already in use in customers' networks, the QVP,
integrated with Ditech Communications' Voice Quality Assurance
(VQA(TM)) software, enables mobile service providers to reduce
capacity expansion costs by up to 90% while improving voice
quality. Increase Capacity with Improved Sound Quality One of the
methods to cost-effectively increase capacity in GSM networks is
the utilization of Half-Rate voice compression. Half-Rate vocoders
provide an economical channel capacity solution, but their use is
often limited because they are associated with degraded voice
quality. The QVP system with VQA software dramatically improves the
sound of many Half-Rate calls making them as good as or better
than, those experienced on Full Rate channels while consuming only
half of the radio network capacity. The noise reduction
capabilities of VQA also improve the performance of downlink DTX
which may lead to additional capacity improvements in the network.
In mobile networks, signal weakness, ambient noise and the effects
of speech transcoding, all adversely impact call quality. The QVP
system with VQA software addresses these impairments with noise
cancellation and enhanced speech intelligibility features to
significantly improve voice quality performance in the mobile
network. "I am excited by our ability to provide this very
cost-effective solution which will enable service providers to ease
their capacity constraints while continuing to provide a superior
listening experience for their mobile subscribers," said Tim
Montgomery, Ditech Communications president and CEO. "The QVP
system has already demonstrated that it can significantly improve
the quality of calls in GSM Half-Rate transmissions where the
impact of background noise is more severe and calls are more
susceptible to impairments." Availability Ditech Communications'
QVP systems offer four T1 or E1 interfaces and are available with a
complete suite of VQA software features for improving the
end-user's listening experience, especially on mobile networks. The
QVP-E family with four E1 interfaces targeted for international
deployment, is now generally available in the 400 and the 800
series with a choice of voice processing resources that provide
voice quality improvement tailored to network requirements. The
QVP-T family with four T1 interfaces, targeted for the North
American market, is now available for trials. The QVP is part of
Ditech Communications' family of voice processing platforms that
range from the SX with a single T1/E1 interface to the industry's
first Broadband Voice Processor (BVP) with OC-3 interfaces. Ditech
Communications Corporation Ditech Communications Corporation is a
global telecommunications equipment supplier for voice networks.
