Randall Stephenson at AT&T "needs 1 gig speeds." and promises "1 gig speeds ubiquitously." Sckipio is ready to start delivering, with 212 MHz Amendment 3 chips soon to sample to selected customers - including AT&T suppliers. Using 212 MHz of spectrum almost doubles the capacity of G.fast, reaching close to 2 gigabits between upstream and downstream in lab conditions.
1.5 gigabits downstream should be achievable over the short loops typical in apartment buildings. Adtran and Huawei have demo'd external boxes that can vector 48-96 ports, but Sckipio does not require the complexity of external vectoring. Instead, the first DSLAM supports 24 or 48 ports and can be daisy-chained with others on demand. This reduces the initial capex.
cDTA allows switching between upstream and downstream for each line.
My line could be set to 500 megabits downstream most of the time. With cDTA, if we need to upload one of Jennie's videos it could switch to 500 megabits upstream. A typical user perceives much higher speeds.

Reality check: While samples have been promised to developers in the next few months, it could easily be a year before volume deployments.
Broadcom has already done lab tests of 212 MHz chips, although they've released so little information it's not clear what will be available when.
Re: The headline figure "150 Gigabits, 212 MHz, 96 Port." The new G.fast should be able to deliver close to 2 gigabits throughout a medium building. It's certainly possible that 96 ports could draw 150 gigabits. In practice, few homes will be drawing more than a small fraction of the peak speeds very often. Remember, two HD TV streams and someone surfing only requires 10-15 megabits. Operators are confident that 10 gigabits of backhaul will be enough for congestion to be minimal or less.
Sckipio Announces World’s First 96-port Gfast DPU
Amendment 3 EVM delivers gigabit speeds to 4 times more subscribers
RAMAT GAN, ISRAEL – September 18, 2017 – Sckipio, the leader in Gfast chipsets, announced the world’s first 48-port, gigabit-capable Gfast distribution point unit (DPU) that can be connected together to support 96 ports. The Sckipio DP2-48- V6-2201 uses the breakthrough new SCK-23000 chipset and Gfast Amendment 3’s 212a profile. By using the 212a profile instead of the 106a profile, Sckipio delivers the extra capacity often needed to achieve true 1Gbps downstream rates.
“Our vision is simple – telcos need to deliver a full gigabit to as many subscribers as possible,” said David Baum, CEO of Sckipio. “Sckipio’s 96-port solution delivers 4 times more gigabit coverage than our rivals.”
The Sckipio DPU evaluation unit comes standard with 48 ports of Gfast running on the 212a profile. To reach 96 ports, an additional 48-port Gfast DPU is connected and both devices coordinate to vector across all 96 ports using Sckipio’s revolutionary cross-DPU vectoring technology. By doing so, telcos can offer true 1Gbps downstream service to 96 concurrent subscribers over the same copper binder.
“Together, we have helped make Sckipio the most widely deployed Gfast technology in the world,” said Greg Bathrick, Solutions Marketing Director, Gfast at Calix. “This next-generation chipset from Sckipio will extend that lead by enabling companies like ours to deliver gigabit capable solutions into unreached and underserved high-density MDUs around the globe.
“Up until now, cable MSOs have been leading in the push for gigabit speeds as they upgrade to DOCSIS 3.1,” said Teresa Mastrangelo, Principal Analyst for Broadbandtrends. “However, the ability for telcos to offer gigabit broadband services via a Gfast solution provides a time-to- market advantage that will help the telcos not only keep broadband market share, but likely grow their share as well.”
The Sckipio DP2-48- V6-2201 delivers record-breaking performance through two important Sckipio innovations:
- High Density: Sckipio’s internal distributed vectoring allows for high port densities while using the 212a profile – without the need for external
- Cross-DPU Vectoring: Sckipio’s ability to vector across multiple DPUs to enable telcos to grow to 96 ports over time as take rates grow.
The solution will ship to customers in Q4, 2017.
SCKIPIO ANNOUNCES BREAKTHROUGH GFAST AMENDMENT 3 CHIPSET
23000 family of chipsets delivers 2Gbps speeds, cross-DPU vectoring and cDTA
RAMAT GAN, ISRAEL – September 18, 2017 – Sckipio, the leader in Gfast, took a major step in delivering the full promise of true gigabit speeds over twisted pairs and coax by releasing the SCK-23000 family of chipsets. This next-generation Gfast solution supports up to 2Gbps in both downstream and upstream directions. The Sckipio solution delivers gigabit access speeds to 4 times as many subscribers sharing a single binder than competitive solutions – all without the need for an external vectoring engine.
For even faster speeds, the Sckipio SCK-23000 family is also the first Gfast solution supporting 212 Mhz bonding for both the CPE and DPU. This ensures more subscribers will achieve gigabit speeds in highly challenging locations.
“This chipset is breathtaking,” said David Baum, CEO of Sckipio. “It delivers four times the vectoring capability, twice the bonding speeds, and supports coordinated DTA for symmetric-like performance in both downstream and upstream. This enables a gradual path to capacity that optimizes the CapEx and OpEx for telcos.”
With this chipset announcement, Sckipio is introducing the world’s first cross-DPU vectoring without the need for external vectoring. This allows for smaller DPUs to connect with each other to increase the vectoring port density. For example, it allows 8-port DPUs to be connected together to address different port configurations to 32 ports without requiring additional SKUs to manage and test. In addition, this enables telcos to reduce CAPEX by growing their infrastructure gradually over time instead of overbuilding with external vectoring at the outset.
To increase operators’ competitive differentiation versus cable companies, the new Sckipio solution is also the first commercial product offering coordinated DTA (cDTA) support beyond 1 gigabit in both upstream and downstream.
“Many telcos are under market pressure to support 1Gbps bandwidth services to residential subscribers,” said Julie Kunstler, Principal Analyst, Next-gen Infrastructure at Ovum. “Sckipio’s newest chipset supports this goal cost-effectively while providing seamless pay-as-you-grow options.”
