Systems Enable VoIP Service Providers to Optimize Call Quality
Booth 1220
MOUNTAIN VIEW, Calif., Oct. 15 /PRNewswire-FirstCall/ -- Ditech
Communications Corporation (Nasdaq: DITC), a leader in the development of
voice processing solutions for communications networks, will showcase its
Voice Quality Assurance (VQA(TM)) voice enhancement technology for Voice over
Internet Protocol (VoIP) networks next week at Voice on the Net (VON) in
Boston. The Ditech Communications' exhibition space is #1220.
VQA(TM) technology is available on Ditech's broadband BVP-flex and
narrowband Quad voice processor platforms. VQA(TM), Ditech's voice quality
enhancement application, significantly improves the sound quality of voice
calls in various network environments. VQA(TM) forms the foundation of an
entire range of advanced voice enhancement and network measurement solutions
that address a wide array of issues in packet-based transmissions and enable
service providers to optimize the voice quality of their VoIP networks.
Voice over packet networks present many new voice quality challenges, as
they introduce impairments such as delay (latency), jitter, packet loss and
coding distortion. These impairments affect voice quality either directly (by
interfering with the coding of the speech) or indirectly (by adding delay and
noise). In addition, calls over VoIP networks, like all networks, are affected
by echo, background noise and varying signal levels.
Ditech's VQA(TM) solution, which blends its core competencies of acoustic
and hybrid echo cancellation with additional advanced voice enhancement
features, are designed to solve key quality challenges in the packet-based
network. Integrated onto Ditech's advanced voice processor platforms, VQA(TM)
includes the following voice enhancement features that enable service
providers to improve, measure and manage voice quality:
* Adaptive Noise Cancellation
* Enhanced Voice Intelligibility
* Acoustic Echo Control
* Automatic Level Control
* Hybrid Echo Cancellation
Ditech's products are deployed in VoIP networks where long PSTN tail
delays (exceeding 64ms) introduce unacceptable levels of echo. With extended
tail delay coverage-up to 192ms-Ditech's echo cancellation products
dramatically improve voice quality in enterprise networks by delivering
integrated voice quality features that eliminate acoustic echo, reduce
background noise and automatically adjust for varying signal levels.
Hear The Difference
Visitors to the Ditech Communications booth will have an opportunity to
listen to examples of calls made with Ditech's voice quality improvement
technology currently in use in wireless and wireline networks and experience
the improved voice quality offered by VQA(TM).
