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.
