COMMUNICATIONS CHOOSES TELCHEMY FOR INTEGRATED IP
PERFORMANCE MONITORING
Integrates VQmon/EP into
Packet Voice Processor to enable deployment of scaleable,
carrier-grade VoIP services
San Jose, CA - March 15, 2006 –
At Spring VON 2006, Telchemy,® Incorporated, the
global leader in VoIP fault and performance management
technology, announced that Ditech Communications Corporation
(NASDAQ: DITC), has integrated VQmon/EP™ VoIP
performance monitoring technology into its Packet
Voice Processor™ voice processing platform.
VQmon/EP will help Ditech Communications enable carriers
to deploy scaleable, carrier-grade VoIP services.
Ditech Communications will incorporate
Telchemy’s market leading VoIP call quality
monitoring technology to offer carriers robust real-time
monitoring and voice quality measurement of voice
channels across the network. With Telchemy’s
technology, Packet Voice Processor will enable carriers
to ensure total voice quality, recognize and identify
network related call quality problems, and provide
advanced reporting for network planning and customer
SLAs.
VQmon/EP detects packet loss and
jitter buffer discard events, utilizes key speech
information from DSP software and produces call quality
scores and diagnostic data. VQmon is based on the
ITU E Model with many extensions to improve accuracy
under time varying network conditions, wideband codecs,
orthogonal impairments and signal related parameters.
Network operators and system administrators use Telchemy’s
VQmon technology to detect, monitor and resolve call
quality and network related problems for networked
multi-media services, including Voice and Video over
IP and to support active QoS control applications
such as call admission control.
“Telchemy’s VQmon enables
us to deliver an unprecedented voice quality management
capability on our Packet Voice Processor,” said
Dr. Chalan Aras, Vice President of Marketing at Ditech
Communications. “VQmon’s ability to go
beyond packet statistics to integrate actual speech
measurements into the ITU E Model to estimate a more
accurate voice quality measurement will enable service
providers using the Packet Voice Processor to truly
understand the subscriber experience and deliver the
best VoIP service”.
Designed to address the voice quality
and interoperability problems of the VoIP network,
Ditech's Packet Voice Processor is integrated with
a comprehensive set of voice processing features that
ensure consistently good voice quality while maximizing
carrier service offerings. Ditech's codec transcoding
feature provides support for a broad class of voice
codec transcoding, while unique voice quality enhancement
capabilities ensure high quality VoIP service delivery
with best-in-class scalability and density. The advanced
voice processing architecture of the Packet Voice
Processor supports nearly 50,000 transcoding sessions
per rack with very low delay.
“Telchemy and Ditech both
share a strong commitment to delivering the highest
quality VoIP calls,” said Alan Clark, President
and CEO of Telchemy, Incorporated. “Integrating
VQmon/EP into Ditech’s voice processing platform
helps it meet the high expectations of its carrier
customers.”
VQmon generates listening and conversational
quality MOS scores and R factors and a wide range
of diagnostic data, making these available through
an API as raw metrics, RTCP XR and SIP QoS Report
payloads. VQmon is the first VoIP Performance Management
software to support the new VoIP management protocols,
providing the essential metrics for the International
Engineering Task Force (IETF) RFC 3611 (RTCP XR) media
path reporting protocol and QoS reporting protocols
for SIP, H.323, MGCP, Megaco and PacketCable.
