Fibre-to-the-premises (FttP) is the least faulty technology in NBN’s arsenal, according to figures disclosed by the company.

Responding to Senate Estimates Questions on Notice, the company responsible for the National Broadband Network (NBN) broke down its 409,821 faults lodged in fiscal year 17-18 by technology.

In absolute terms, fibre-to-the-node (FttN) led the way with 216,000 faults, followed by HFC with 84,300, and FttP with 75,000. NBN’s most recently launched technology choice, fibre-to-the-curb (FttC), had only 81 faults, while fibre-to-the-basement (FttB) had 6,800 faults lodged, satellite had 6,000, and fixed wireless had 21,000.

When translated to faults per 100 active premises, the technology in the order of most faults to least are: HFC, FttC, FttN, fixed wireless, FttB, satellite, and FttP.

NBN noted the period covered its HFC pause, where sales on the network were stopped while it was remediated, and since its relaunch, faults have occurred at a rate of 1.4 faults per active premises, which would place it between FttC on 1.6 and FttN on 1.2.

Overall, the fault rate for fiscal year 17-18 sat at 1 fault per 100 active premises per month, while for 16-17 the rate was 0.89, and from July 2018 to the end of February the overall fault rate was 0.91.

Custom remediation means 90% chance of NBN resolving your issue in 2 years

If you feel you are in a bad place with your connection to the NBN, spare a thought for the unlucky people on NBN Co’s custom remediation list.

According to the company, custom remediation is used for premises that need to have long cable runs replaced, involve construction work, or need to be redesigned to move to another technology.

“NBN Co aims to resolve 90 percent of cases within 2 years of opening. This timeframe allows NBN Co to conduct detailed investigation, and custom design and build works on a case-by-case basis to remediate premises,” the company said in response to Senate Estimates Questions on Notice.

NBN added it had 713 custom remediation cases awaiting resolution, and had completed 10 cases.

In another question, NBN said around 7.6% of its FttN services were unable to reach the mandated 25Mbps minimum speeds, however some lines were in the coexistence period where FttN connections ran slower due to needing to continue support for legacy services over copper, such as ADSL, during an 18-month migration window.

“The actual experience of customers using the network, can be impacted by other factors such as their in-home set-up and equipment,” NBN said.

“Where the network is not capable of providing the minimum wholesale download speeds after co-existence has ended, NBN will take action to rectify any issues in its network so that minimum standards are met.”

Previously the company said in August 2017 that 6% of FttN connections could not reach 25Mbps.

NBN added it was running speed assurance trails for FttN connections that were deemed at risk of not hitting 25Mbps, with the broadband wholesaler saying that if a line suffered a 20% drop in downstream or upstream performance, then the retailer could log a fault for NBN to investigate.

Earlier this week, the NBN disclosed it had almost doubled the total amount of copper it has purchased since October 22, 2017.

As at 19 February 2019, NBN Co has purchased 29,460km of copper cable, which has typically been used for the link between existing pillars and new nodes.”, the company said in response to a Senate Estimates Questions on Notice published this week.

“A significant proportion of this figure is also due to FTTC network construction for short extensions of copper lead-in cables to the FTTC DPU location.”

The company also revealed that less than half of the premises in its fixed wireless areas had taken up such services, and fibre-to-the-node (FttN) uptake was tracking lower than the company needed to meet its financial goals.

iPhone 14 May Debut In An Online-Only Event With Pro Price Hike



The iPhone 14 will bring plenty of changes this year, but most of them are apparently being reserved for the Pro models. The base models are also expected to feature a big change, but not one that some people will like — Apple may finally say goodbye to the 5.4-inch iPhone mini and go in the opposite direction by introducing a non-Pro iPhone Max. While that would be a tragedy for those who love small iPhones, it would also consolidate Apple’s smartphone collection and make it easier for buyers to understand what’s available.

The next-generation iPhone lineup will reportedly have two 6.1-inch models and two 6.7-inch models split between base and Pro lines. While there will be some upgrades across the board, the biggest changes will no doubt be seen on the iPhone 14 Pro and iPhone 14 Pro Max. The most visible will be — at least according to the rumors so far — the switch to a pill-shaped cutout, which would mean finally ditching the bucket notch that debuted with the iPhone X in 2017. New and improved cameras will likely be found inside the iPhone 14 Pro models, too, as well as a faster processor.

These upgrades won’t come without costs, however, and Apple may have buyers shoulder some of that. An investor note shared by Philip Elmer-DeWitt claims the Pro models will experience a $100 price increase. The current iPhone 13 Pro already starts at $999 and the iPhone 13 Pro Max begins at $1,099, so that would be quite a significant price hike. Apple is also expected to increase the storage in these iPhone models to make those figures easier to swallow, but it may still cause some interested buyers to pause when deciding which of the four iPhone 14 models to pick.

Dodge Charger Daytona SRT Concept Teases Electric Muscle Cars To Come



Three patented new features help give the Daytona SRT an edge. The e-Rupt multi-speed transmission system offers an “electro-mechanical shifting experience that’s pure Dodge,” the automaker says. The new transmission has a PowerShot boost system similar to the one included in the hybrid versions of the upcoming Dodge Hornet. Press a button on the steering wheel and you’ll get a bit of extra horsepower and some torque along with it — it’s for those occasions when you need to power past something on a highway, or if you need to take off from a standing start fast enough to tear a small hole in the fabric of time and space.

There’s a new aerodynamic pass-through feature named the “R-Wing” that gives the concept a performance edge while connecting it with its NASCAR record-breaking ancestor. Then, for muscle car enthusiasts who are upset the switch to electric may preserve someone in their vicinity’s eardrums, there’s the Fratzonic Chambered Exhaust. It’s an industry first, and as loud as a Hellcat at 127 decibels, so even though you’re being powered by a battery, people will still hear your muscle car coming. The system is a patented industry-first feature. Sound is produced electronically before being forced through an amplifier and “tuning chamber.” It is then blasted out of the car’s back end, recreating the muscle car audio experience without any of the emissions.

The Dodge Charger Daytona SRT is just a concept, so while you may be impressed by the noise both Dodge and its car are making, you won’t actually be able to buy one. However, there’s a good chance most — if not all — of its features will appear in Dodge’s first commercially released EV, which is scheduled to arrive in 2024.

The Reason Why Lamborghini Will Never Build A Manual Transmission Car Again



By January 2014, very few Gallardos were ordered with a manual gearbox — so few, in fact, that AutoGuide quoted company CEO Stephan Winkelmann as saying that the automaker’s team would have to double-check with the dealership from which the order was received to make sure the manual transmission request wasn’t an error.

Besides the lack of demand for cars with a manual transmission, Lamborghini’s advanced driving tech starting with the Huracán also warranted complete control over the vehicle, and the manual use of a clutch could potentially cause disharmony. In 2016, Reggiani said in an interview with Road & Track that engaging the clutch “creates a hole in the communication between what the engine is able to provide and how the car reacts to the power of the engine.”

The executive also said during the interview that even though the decision to drop the manual transmission option wasn’t easy, the automatic chassis control systems on newer Lambos meant there wasn’t really any other option. “If you want to control the power, the clutch must be under the control of the brain of the car, not your brain,” Reggiani said.
