New SD-Access innovation acts as bandwidth valve; auto-adjusting
upstream and downstream ratios in response to user application
behaviour, accelerating Gigabit services
LONDON--(BUSINESS WIRE)--Oct. 18, 2016--
ADTRAN®, Inc., (NASDAQ: ADTN), a leading provider of next-generation
open networking solutions, today announced the availability of a new
capability for G.fast deployments – Dynamic Time Allocation (DTA) – that
allows subscribers to maximize the total bandwidth of a G.fast
connection by transmitting data upstream or downstream intelligently to
provide a fibre to the home (FTTH) user experience. ADTRAN has been
demonstrating this innovation to operators globally for low crosstalk
G.fast environments, providing operators an alternative to installing
Cat 6, Cat5e or fibre optic cable to provide symmetric Gigabit data
rates.
DTA disrupts the concept of Time Division Duplex (TDD) used by G.fast
and other broadband access technologies which, until now, have been
based on the “set-and-forget” configuration of uplink and downlink
ratios (either symmetric or some degree of asymmetric) at the G.fast
distribution point unit (DPU). DTA responds to user activity in the
order of milliseconds, equipping the user with full stream broadband
performance while giving the perception of a full capacity symmetric
broadband experience. This approach achieves up to double the speed of
an equivalent symmetric G.fast broadband service delivered without DTA.
In instances where simultaneous upstream and downstream transmission is
required, DTA responds as appropriate.
“ADTRAN G.fast customers have a unique opportunity to differentiate
their services with an intelligent, new software-defined networking
capability that meets dynamic customer demand with maximum performance,”
said Ronan Kelly, CTO for EMEA and APAC at ADTRAN. “With DTA,
configuration symmetry is irrelevant. Operators can deploy responsive
broadband for the first time, bursting to the full bandwidth potential
of the subscriber connection in either direction. This fibre-like
capability takes G.fast performance to a new level, matched only by the
advanced optics standards such as NG-PON2 and XGS-PON.”
DTA is suitable for low crosstalk environments such as single pairs or
coaxial cable. Available as a software feature on its 500G series of
G.fast solutions, the new DTA capability is set to be deployed by a Tier
1 U.S. operator during its G.fast rollout later this year.
“G.fast technology has accelerated, both in terms of the first phase of
standards completion and in product development. Chipsets are on the
market and an increasing number of Communications Service Providers
(CSPs) are conducting trials,” wrote Ian Keene, research vice president
at Gartner. “Initial commercial deployments are expected in 2016 and
shipments are forecast to ramp up during 2017. This fast pace of
technology development has been driven by CSP demand; many are attracted
by the possibility of high bandwidth services that can meet today's
demands without the cost and time delays of pulling fiber all the way
into the home.” 1
