Orascom Telecom Ramps Up Deployment of Ditech Networks' Products
(Wireless News Via Thomson Dialog NewsEdge)
Ditech Networks, a provider of voice quality solutions to the world's
communications industry, said that Orascom Telecom is completing full
deployment of Ditech's products in its Djezzy GSM mobile services
network in Algeria after an audit showed a measurable increase in voice
quality.
Orascom Telecom Algeria is a division of Orascom Telecom Holdings, one
of the largest mobile service providers operating in the Middle East,
Africa and South Asia.
Orascom is completing deployment of Ditech's Voice Quality Assurance
(VQA) solution after conducting a voice quality audit of its Djezzy
network. The audit was implemented utilizing Ditech's Experience
Intelligence (EXi) solution, which measures the impact of voice quality
impairments from the caller's environment on the mobile call
experience. After monitoring and analyzing call data over a four-week
period, the audit showed that VQA increased Djezzy's MOS value (Mean
Opinion Score) up to a full half-point.
"A 0.5 improvement in MOS is significant and will result in a
measurable decline in subscriber churn," said Nagi Abboud, Chief
Operation Officer of Djezzy in Algeria. "Ditech's voice quality
solution is delivering to our subscribers a consistent, reliable call
experience that is creating real differentiation in the marketplace."
Ditech's VQA solution enables Djezzy to unobtrusively and proactively
reduce and remove voice quality impairments, including ambient noise,
echo and mismatched speech levels, giving subscribers a consistent,
high-quality call experience no matter where they are located, or in
what environment they are making the call.
The impact of VQA on Djezzy's subscribers was quantified utilizing EXi.
EXi captures uplink and downlink data live calls, and produces a MOS
value based on the ITU G.107 E-model. In the Djezzy network, EXi
analyzed background noise, acoustic echo and voice level mismatches,
enabling Orascom to combine knowledge of its subscribers' call
experience with existing network-based tests. This combination of
information gives Orascom a comprehensive view of voice quality as it's
actually delivered to subscribers.
"Orascom has become an industry leader in fully understanding and
managing voice quality that's delivered to their subscribers," said
Todd Simpson, President and CEO of Ditech Networks. "Many of the
world's mobile carriers evaluate voice quality solely from a network
perspective, which is only part of the picture. Orascom looks at the
entire subscriber experience, and delivers to its customers consistent,
high-quality mobile service."
Communications providers worldwide often use MOS as the primary measure
of voice quality. In mobile networks, a MOS value is typically derived
from tests that measure the impact of network infrastructure on voice
quality, but not voice quality impairments that occur in the caller's
environment. Until the introduction of EXi, voice quality impairments
in the callers' environment, which total up to 30 percent of all
problems on mobile calls, could not be fully quantified.
Ditech's EXi and VQA solutions provide the communications industry a
comprehensive approach to managing voice quality. EXi non-intrusively
monitors and measures voice quality on all live calls, and delivers an
industry- standard voice quality score that reflects the subscriber
call experience. VQA mitigates network-induced voice quality
impairments and impairments from the caller's environment in real-time,
on both ends of the call. Both products are integrated with Ditech's
broad range of voice processor platforms, which cost- effectively
deploy the solution across carrier networks.
Orascom Telecom is an international telecommunications company
operating GSM networks in seven high growth markets in the Middle East,
Africa and South Asia.
