NTT and the Broadband Forum have teamed up to standardize the virtualization of operators' PON networks to support time-critical applications including 5G fronthaul.
NTT's Access Network Service Systems Laboratories -- which conducts research and development into areas such as enhancing fiber-to-the-home (FTTH); optical media networks; infrastructure technologies and wireless access -- is part of the combined team researching how operators can use software-defined networking, network functions virtualization and software to upgrade PON networks to accelerate new-service delivery according to a statement from NTT Communications Corp. (NYSE: NTT) and Broadband Forum .
This includes fronthaul for 5G services, a topic of major concern to many service providers as they look to converge fixed and mobile networks.
"As users' usage changes, both in regard to the different services required and the amount of data coursing through fiber networks, operators need to update their PON networks, including by adding TCAs," said Akihiro Otaka, executive manager at NTT Access Network Service Systems Laboratories. "This used to require the remake of PON equipment for each service, but should be done via a software upgrade in the near future to improve cost-effectiveness."
With operator demand growing, the industry needs standards to ensure vendor-agnostic systems are in place and mass deployment can ensue, he said.
Dubbed "PON Abstraction Interface for TCAs," the project examines how SDN and NFV can apply to optical line terminals (OLTs) to disaggregate PON functions to functional modules with open interfaces. In the first phase, participants will define interfaces' disaggregation policy and functional requirements to disaggregate those PON functions that need time-critical processing. The second stage will drill into defining the detailed specs of the interfaces as APIs.
More than a half-million Irish residents expected to have fiber broadband by 2020. But Ireland's National Broadband Plan has not even begun — and government officials today postponed any agreement again.
In a new report and searchable database, Broadband Now discovered fiber is the is the least expensive technology powering subscribers' connections. But the poorest, most rural residents pay the most for connectivity, regardless of underlying infrastructure.
As Vice President of Global Healthcare at AT&T, Maria Lensing oversees the telecommunications operator's technology and professional services offerings across the spectrum of medical providers, from solo practitioners and walk-in clinics to giant hospital chains, medical-device vendors and consulting firms. Lensing also sees more interest from traditional service providers -- cable and telecom operators looking to expand or build relationships with their own medical communities, perhaps as an adjunct to smart-home successes or standalone.
Lensing, who took on this role almost a year ago in May 2018, oversees both the sales and technical teams responsible for developing growth initiatives for AT&T's Global Healthcare business -- including products, services and industry-specific solutions. She also very actively promotes business minority inclusion, education and female empowerment programs and has been recognized both within and outside AT&T. Some awards she's received include "Top 40 Under 40" and "Super Woman in Business" from the Memphis Business Journal.
Join Maria Lensing, VP of Global Healthcare at AT&T, on Tuesday, April 23 at 12:00 p.m. ET / 9:00 p.m. PT, when she's the guest on BBWN Radio, hosted by Broadband World News Editor Alison Diana. Register now!
So far, the agenda includes a discussion of technologies such as fiber and 5G; defining the needs and solutions for a widely diverse range of customers; partnering for success in a typically slow-moving, budget-constrained market; learning and dispersing best practices from other verticals and within other business groups; promoting diversity and female empowerment when so many say they're doing so but so little has changed; and what she hopes to accomplish in another year in this role.
Register and post your questions for Maria on BBWN Radio's easy-to-use chat board. We will get to as many questions as possible. Please post questions before and during the broadcast. Once you've registered, you will be led to the chat board page. Talk to you on April 23!
Tune in to Broadband World News Radio on February 14 at 11 a.m. ET / 8 a.m. PT / 4 p.m. UK when John Isch, Practice Director of the Network and Voice Center of Excellence at Orange Business Services, discusses use cases, ROI and misconceptions of software-defined wide-area networks, virtualization and cloud.
Just when you thought the answer to your next technology direction question was clear, the noise around multiple new technology options fills the Internet and airwaves. Multiple 5Gs are being deployed; there's CableLabs' 10G initiative; the ITU and IEEE are toiling around 50G PON – and we haven’t even talked about Wi-Fi6 yet! Is any of this real, do you have to pay attention or can you just let the dust settle and then decide?
Since waiting is often not the best option, let’s demystify technology options, their impact on your business, and how to prepare for whatever the future brings.
In this webinar, Service Providers will learn:
Current state of 5G and how it affects everyone, not only mobile network providers.
Latest technologies being developed and how they will benefit their networks and subscribers.
How to prepare their networks for the future – whatever it may hold.
