Adax, SURF and RadiSys deliver ATCA-based
LTE
Adax, SURF Communication Solutions and RadiSys, have announced
the successful delivery of a key component in the migration
to LTE - CSFB (Circuit Switched Fallback) - to a major APAC
provider of integrated wireless solutions.
CSFB enables mobile operators to quickly and economically
roll out voice services in conjunction with their LTE networks.
It allows mobile devices to "fall back" to GSM
or UMTS domains for incoming or outgoing voice calls, Subscribers
maintain access to the wide array of rich circuit-switched
capabilities, including international roaming while enjoying
LTE broadband access to the Internet. The joint solution
is NEBS-ready and built by integrating Adax' flexible HDC3
interface cards and SURF's voice processing subsystem into
RadiSys' ATCA server platform.
Udi Shani, SURF's President & CEO explained, "We
see a great potential for LTE I-TDM solutions available
with this strategic alliance. The SURF ATCA solution provides
customers with high performance capabilities by providing
all IP and TDM media handling through SURF's powerful software
running on high performance DSP's." Udi continued,
"SURF is a leader in I-TDM and media processing technology,
and we are proud to provide this leading technological advanced
solution for our customers allowing them to be competitive
in the LTE ecosystem in a record time to market."
"As a redundantly designed system, cards and blades
may be added, removed, and re-allocated with no loss of
service. The flexible ATCA architecture fulfils the promise
of cost-effective multi-vendor solutions. Adax, SURF, and
RadiSys understand that this can only be achieved in short
time-to-market through close cooperation amongst committed
ecosystem partners," said Venkataraman Prasannan, general
manager, ATCA Business, RadiSys. "This is another example
proving that ATCA is on a firm ground as TEMs' preferred
vehicle for next-generation network deployments."
The joint CSFB solution was designed for existing TDM-based
network services. RadiSys' carrier-grade ATCA-6006 5U platform,
equipped with SBCs and carrier blades, hosts the Adax HDC3
and SURF/Rider AMC cards. Legacy voice and SS7 signaling
enter the system on TDM links via the HDC3 T1/E1 ports.
Voice channels are interworked to IP using I-TDM and sent
to the SURF/Rider card, which transmits VoIP packets to
the network. Data services are handled by the LTE network
or the legacy interface when there is no LTE connection.
The partners also offer 3G solutions interworking ATM voice
traffic to IP.
" No single vendor can meet the complex needs of today's
evolving telecommunications networks," said Drew Sproul,
Adax Director of Marketing. "Close cooperation among
all parties, focusing on the customer requirements, is essential
to success, as we demonstrated here. Adax looks forward
to many more such successes with RadiSys and SURF."
