VDSL2 vectoring and G.fast are only as good as the copper wiring that extends to each customer. Up to 45 percent of North American wire pairs are in some state of disrepair.

Verizon has no interest in using advanced forms of DSL as part of its next generation broadband service.

Speaking at ADTRAN’s Broadband Solutions Summit, Verizon’s director of network planning Vincent O’Byrne made it clear DSL variants and copper wiring were not going to be a part of Verizon’s future network platform.

“We have no strategy for G.fast,” O’Byrne told Telecompetitor in response to a question about whether the company would upgrade or deploy advanced forms of DSL as part of overhauling its broadband networks.

Some telephone companies with large legacy copper networks have promoted DSL advancements including bonding, VDSL, and G.fast in lieu of costly fiber upgrades to shareholders and customers to improve the sluggish 6-10Mbps speeds many customers get from DSL service. But O’Byrne said Verizon has had nothing but headaches trying to make its legacy copper network actually deliver the improved broadband speeds those technologies promise on paper.

O’Byrne admitted Verizon’s copper network has not aged well, calling it “poor” in some areas. Verizon’s previous efforts to deploy VDSL and ethernet over copper to multiple dwelling units (MDUs) like apartment buildings and condos turned out so poorly, O’Byrne does not want to repeat those mistakes in the future.

For urban areas and MDUs, O’Byrne stressed he plans to take fiber all the way to each condo unit or apartment and get rid of the copper.

Verizon’s next generation fiber strategy will depend heavily on NG-PON2 technology, which is managed by unpowered splitters and filters — dramatically cutting the hardware costs associated with active fiber networks. Many PON networks are fiber to the premises, but then rely on Wi-Fi or Ethernet wired networks once inside a building. Verizon prefers an all-fiber solution, which is unusual among U.S. carriers. AT&T, CenturyLink and Windstream still use G.fast for relatively short runs of existing copper phone wiring inside MDUs and homes.

Verizon’s O’Byrne believes an all-fiber solution may cost more upfront, but will deliver better longevity, value, and fewer problems over time.

Only half of CenturyLink’s customers in well-populated areas formerly served by Qwest can buy broadband service at 40Mbps or higher, while rural customers fare considerably worse with less than 25% able to get High Speed Internet at those speeds.

Customers have noticed and at least 65,000 canceled their broadband service with the phone company in the second quarter of this year, most presumably switching to their area’s cable operator.

“CenturyLink is by far the most abysmal telephone company I’ve ever had to deal with and I’m 63 years old,” shares Glen Canby in Arizona. Canby is a retired telephone company engineer that spent 40 years with a larger phone company serving the midwestern U.S.  “Their reviews online echo my own experiences, which have ranged from being quoted one price while being billed another, being locked into a term contract you didn’t ask for, and getting only a fraction of the speed they claim to sell.”

Canby is counted as one of CenturyLink’s 40Mbps-qualified customers, yet he actually receives less than 6Mbps service.

But that isn’t what CenturyLink tells the Federal Communications Commission. In a semi-annual broadband deployment report, the company claimed 51 percent of their customers in urban and suburban former Qwest service areas can subscribe to 40Mbps DSL or higher. But whether a customer is “qualified” to buy 40Mbps service is not the same as actually getting the speeds the company markets.

CenturyLink attempts to cover their claims with fine print attached to their FCC submission: “The numbers shown in this chart reflect the percentages of households served by DSLAMs that are capable of providing the specified broadband speeds.” (A DSLAM is a network device typically used to extend faster DSL speeds to customers by reducing the amount of copper wiring between the telephone company’s central office and the customer’s home. Customers in a neighborhood typically share space on a DSLAM, in effect sharing a single connection back to the phone company.)

“That’s clever of them, because of course the DSLAM is just one link in the chain that ends with the ‘last mile’ between that equipment and my home, and that is where CenturyLink’s phone plant is at its weakest,” Canby writes. “I spent 20 years at a phone company dealing with last-mile DSL speed issues, so they cannot fool me.”

Canby blames the condition of CenturyLink’s infrastructure between the DSLAM serving him and his home for the problems, as well as overselling DSL service by packing too many customers onto a single DSLAM.

“It might be 40Mbps service at the remote end, but it drops to around 6Mbps on a good day by the time it reaches my house,” Canby complains. “Once the sun goes down, the speed drops to 3Mbps, which is a classic case of overselling to me because too many people are trying to share one connection at the same time. It has been this way since 2008 according to my neighbors.”

Back then, phone service was provided by Qwest, the former Baby Bell providing service in 14 sparsely populated western U.S. states — Arizona, Colorado, Idaho, Iowa, Minnesota, Montana, Nebraska, New Mexico, North Dakota, Oregon, South Dakota, Utah, Washington, and Wyoming. Qwest was acquired by CenturyLink in 2011.

CenturyLink has promised to improve broadband speeds for former Qwest customers, but much of what counts as progress has been in more urban areas, while rural customers continue to languish. The company admits just 21.9 percent of rural households can get 40Mbps service. Only 47.6% can buy 12Mbps, 61.3% can get 5Mbps, and 83% can subscribe to 1.5Mbps. That leaves 17% of former Qwest customers with no broadband options at all. CenturyLink did not break out the percentage of customers that meet the FCC’s 25Mbps minimum speed definition of broadband.

“This is why CenturyLink loses customers to cable operators who have no problems trying to deliver internet access over their network, because it was built to support more bandwidth,” Canby shares. “They can usually deliver the same internet speed to customers no matter how far out they live while phone companies deal with a network built for making phone calls, not data.”

Company officials recognize they could do better and have promised investors another 2.5 million customers will be able to reach 40Mbps by the end of 2017. By the end of the year after that, CenturyLink hopes to reach 85% of customers with VDSL2, bonding, and vectoring technology to achieve 40Mbps service for most customers in their top 25 markets. But rural customers are likely to left waiting longer because of the costs to upgrade Qwest’s copper-based network, especially in smaller states like Idaho, the Dakotas and Wyoming.

“The only answer is cable or fiber broadband, and if you live in a small community it could be years before CenturyLink gets around to you,” Canby writes. “If it’s the same story all over town, I’d start advocating for a community-owned fiber network and not sit around and wait for CenturyLink to act, especially if there is no cable company in town.”

With video streaming now accounting for at least 64 percent of all Internet traffic, it should have come as no surprise to Australia’s ISPs that as data caps are eased and popular online video services like Netflix arrive, traffic spikes would occur on their networks as well.

It surprised them anyway.

Telecom analyst Paul Budde told the WAToday newspaper “video streaming requires our ISPs to have robust infrastructure, and to use it in more sophisticated ways, and that largely caught Australia off guard. I think it’s fair to say everybody underestimated the effect of Netflix.”

Not everybody.

Australia’s National Broadband Network (NBN) was originally envisioned by the then Labor government as a fiber-to-the-home network capable of enormous capacity and gigabit speed. Prime Minister Kevin Rudd proposed buying out the country’s existing copper phone wire infrastructure from telecom giant Telstra to scrap it. Instead of DSL and a limited number of cable broadband providers, the national fiber to the home network would provide service to the majority of Australians, with exceptionally rural residents served by wireless and/or satellite.

Conservative critics slammed the NBN as a fiscal “white elephant” that would duplicate or overrun private investment and saddle taxpayers with the construction costs. In the run up to the federal election of 2013, critics proposed to scale back the NBN as a provider of last resort that would only offer service where others did not. Others suggested a scaled-down network would be more fiscally responsible. After the votes were counted, a Coalition government was formed, run by the conservative Liberal and National parties. Within weeks, they downsized the NBN and replaced most of its governing board.

Netflix’s launch increased traffic passing through Australia’s ISPs by 50 percent, from 30 to 50Gbps in just one week, and growing.

Plans for a national fiber to the home network similar to Verizon FiOS were dropped, replaced with fiber to the neighborhood technology somewhat comparable to AT&T U-verse or Bell Fibe. Instead of gigabit fiber, Australians would rely on a motley mix of technologies including wireless broadband, DSL, VDSL, cable, and in areas where the work had begun under the earlier government, a limited amount of fiber.

In hindsight, the penny wise-pound foolish approach to broadband upgrades has begun to haunt the conservatives, who have already broken several commitments regarding the promised performance of the downsized network and are likely to break several more, forcing more costly upgrades that would have been unnecessary if the government remained focused on an all-fiber network.

Communications Minister Malcolm Turnbull has admitted the new NBN will not be able to deliver 25Mbps service to all Australians by 2016. Only 43 percent of the country will get that speed, partly because of technical compromises engineers have been forced to make to accommodate the legacy copper network that isn’t going anywhere.

Think Broadband called the fiber to the neighborhood NBN “a farce” that has led to lowest common denominator broadband. A need to co-exist with ADSL2+ technology already offered to Australians has constrained any speed benefits available from offering faster DSL variants like VDSL2. Customers qualified for VDSL2 broadband speeds will be limited to a maximum of 12Mbps to avoid interfering with existing ADSL2+ services already deployed to other customers. Only multi-dwelling units escape this limitation because those buildings typically host their own DSLAM, which provides service to each customer inside the building. In those cases, customers are limited to a maximum of 25Mbps, not exactly broadband nirvana. The NBN is predicting it will take at least a year to take the bandwidth limits off VDSL2.

The need for further upgrades as a result of traffic growth breaks another firm commitment from the conservative government.

NBN executive chairman Ziggy Switkowski told reporters in 2013 that technology used in the NBN would not need to be upgraded for at least five years after construction.

“The NBN would not need to upgraded sooner than five years of construction of the first access technology,” Switkowski said. “It is economically more efficient to upgrade over time rather than build a future-proof technology in a field where fast-changing technology is the norm.”

Since Switkowski made that statement two years ago, other providers around the world have gravitated towards fiber optics, believing its capacity and upgradability makes it the best future-proof technology available to handle the kind of traffic growth also now being seen in Australia. At the start of 2015, 315,000 Australians were signed up for online video services. Today, more than two million subscribe, with Netflix adding more than a million customers in less than four months after it launched down under.

Many ISPs offer larger data caps or remove them altogether for “preferred partner” streaming services like Netflix. With usage caps in place, some customers would have used up an entire month’s allowance after just one night watching Netflix.

But the online viewing has created problems for several ISPs, especially during peak usage times. iiNet reports up to 25% of all its network traffic now comes from Netflix. As a result iiNet is accelerating network upgrades.

Customers still reliant on the NBN’s partial copper network are also reporting slowdowns, especially in the evening. The NBN will have to upgrade its backbone connection as well as the last mile connection it maintains with customers who often share access through a DSLAM. The more customers use their connections for Netflix, the greater the likelihood of congestion slowdowns until capacity upgrades are completed.

Hackett

Optus worries its customers have extended Internet peak time usage by almost 90 minutes each night as they watch online streaming instead of free-to-air TV. Telstra adds it also faces a strain from “well over half” of the traffic on its network now consisting of video content.

This may explain why Internet entrepreneur and NBN co-board director Simon Hackett wishes the fiber to the neighborhood technology would disappear and be replaced by true fiber to the home service.

“It sucks,” Hackett told an audience at the Rewind/Fast Forward event in Sydney in March, referring to the fiber to the neighborhood technology. His mission is to try and make the government’s priority for cheaper broadband infrastructure “as least worse as possible.”

“Fiber-to the-[neighborhood] is the least-exciting part of the current policy, no arguments,” he added. “If I could wave a wand, it’s the bit I’d erase.”

Another cost of the Coalition government’s slimmed-down Internet expansion is already clear.

According to Netflix’s own ISP speed index, which ranks providers on the quality of streaming Netflix on their networks, Australia lags well behind the top speeds of dozens of other developed nations, including Mexico and Argentina.

But even those anemic speeds come at a high cost to ISPs, charged a connectivity virtual circuit charge (CVC) by NBN costing $12.91 per 1Mbps. The fee is designed to help recoup network construction and upgrade costs. But the fee was set before the online video wave reached Australia. iiNet boss David Buckingham worries he will have to charge customers a “Netflix tax” of $19.18 a month for moderate Netflix viewing to recoup enough money to pay the CVC fees. If a viewer wants to watch a 4K video stream, Buckingham predicts ISPs will have to place a surcharge of $44.26 a month on occasional 4K viewing, if customers can even sustain such a video on NBN’s often anemic broadband connections.

Some experts fear costs will continue to rise as the government eventually recognizes its budget-priced NBN is saddled with obsolete technology that will need expensive upgrades sooner than most think.

Instead of staying focused on fiber optics, technology the former Rudd government suggested would offer Australians gigabit speeds almost immediately and would have plenty of capacity for traffic, the conservative, constrained, “more affordable” NBN is leaving many customers with no better than 12Mbps with a future promise to deliver 50Mbps some day. There is little value for money from that.

Hong Kong Telecom Group (HKT) chief technical officer Paul Berriman believes copper phone wiring is a thing of the past and is nonplussed by efforts to wring a few more years of life out of infrastructure that cannot reliably support high-speed Internet and is costly to maintain. The only solution that makes sense is to get rid of the copper and replace it with fiber optic wiring.

While America talks about 1Gbps limited rollouts, he is thinking about speeds ten times faster with his announcement Hong Kong Telecom is preparing to launch 10 gigabit service across the territory and was continuing its efforts to tear out obsolete copper wiring.

The man partly responsible for ensuring Hong Kong’s broadband future is a fast and reliable one says HKT has 1.6 million broadband customers — 530,000 on fiber to the home service and 200,000 on less-desirable VDSL2 with vectoring, which still relies in part on copper wiring. He is not happy with copper wiring’s performance and support costs and wants it out of his network. His minimum target speed is 100Mbps and if he finds a building that for any reason does not deliver more than 30Mbps at all times, he instructs engineers to immediately tear out the copper and replace it with fiber.

Berriman

Overall, Hong Kong has an average Internet speed of 87 megabits per second, according to figures by Akamai. “Our (HKT) average is about 116Mbps,” he said. It is about to get much faster. The two major wired fiber competitors are HKT and HKBN and both compete fiercely for broadband customers.

HKT has three tiers of unlimited use fiber broadband (regular prices shown in U.S. dollars, prices lower for certain bundles and promotions):

• 300/300Mbps for $64.21/mo;
• 500/500Mbps for $77.10/mo;
• 1000/1000Mbps for $90/mo.

When the 10Gbps upgrade is complete, HKT is likely to further boost speeds and/or cut prices.

Berriman acknowledges that the densely packed multi-dwelling apartments and condos common across Hong Kong makes large fiber projects less expensive than elsewhere in the world, but believes costs can be managed by deploying incremental upgrades. For example, HKT today has fiber extending into 85 percent of Hong Kong’s buildings and can connect fiber to 79 percent of homes in Hong Kong within three days of receiving an order.

Depending on a customer’s requirements, HKT can save money by serving DSL over short lengths of existing in-building copper wiring for customers not subscribed to ultra-fast broadband speed tiers. The length of wiring is short enough to guarantee speed is not affected for these customers. When customers do need the fastest speeds, fiber is strung directly to their apartment. Despite this, HKT is progressively migrating away from “fiber to the basement” to an all-fiber network to simplify its facilities and increase reliability, especially as the demand for faster speeds continues to grow.

“Once we get to 50 or 60 percent usage of the fiber in the building we start to look at converting the rest to get rid of the [older DSL] electronics,” Berriman said.

HKT also operates a mobile network it acquired from “Sunday” in 2006 and has also bought out Telstra’s share of the formerly joint owned CSL. The wireless company has a 31 percent market share and 4.6 million customers on two different networks — one supplied by ZTE and the other from Huawei. To supplement its wireless mobile network and offload traffic, HKT also operates 14,000 Wi-Fi hotspots across Hong Kong and is a leader in the use of EAP-SIM, which makes it easy for connections to be handed off between its mobile and Wi-Fi networks without interruption.

The new CEO of Frontier Communications is promising more fiber to the home service and advanced ADSL2+ and VDSL2 service to dramatically boost Internet speeds… if you happen to live in a Verizon territory Frontier is planning to acquire in Texas, California, or Florida. For Connecticut customers that used to belong to AT&T, Frontier also plans to spend money to further build out AT&T’s U-verse platform to reach more suburban customers not deemed profitable enough to service by AT&T.

For legacy Frontier customers in other states? Frontier plans nothing beyond what it already provides — usually dismally slow DSL.

Speaking to investors during the JP Morgan Global Technology, Media and Telecom Conference, Frontier CEO Daniel McCarthy said upgrades offer the company new earnings opportunities, but a closer analysis reveals those benefits will only reach customers in areas where Verizon and AT&T already did most of the work and spent the money required to build advanced network infrastructure.

Verizon has spent millions upgrading customers in Texas to its FiOS service and has a significant fiber to the home presence in California and Florida. Because fiber infrastructure is already largely in place, Frontier will not have to spend huge sums to build a new network. Instead, it will spend incrementally to expand service to nearby service areas.

Mediocre broadband in upstate New York.

“The FiOS penetration is much higher, specifically in Texas, but we think there’s a lot of opportunity to drive FiOS penetration in Florida and California,” McCarthy said. “We see that as a big opportunity.”

Fierce Telecom notes Frontier won’t have to make a large investment outside of installing new DSLAMs in remote terminals or local Central Offices to deliver higher speeds over copper. Frontier will likely depend on VDSL2 technology on short copper line lengths in suburban areas and ADSL2+ in rural locations.

“I think in this case it might be replacing some electronics, but it’s not a heavy lift from a construction perspective,” McCarthy said. “By putting in a shelf and next-generation capabilities, whether it’s VDSL, ADSL2+, or all the different flavors you can use to serve the different loop lengths in a market you achieve the ability to bring a fresh product set into an area at a fairly low cost.”

While Frontier is willing to invest money in areas that are easy to upgrade, it has proven itself reluctant to consider major upgrades in its legacy service areas where it acquired traditional copper-based landline networks.

“The new states will clearly have new growth opportunities,” McCarthy said. “In Florida there has been a revival of housing in certain areas and subdivision growth in Texas and California.”

In Connecticut, Frontier will build on the acquired AT&T fiber/copper network with a modest expansion of U-verse.

“We actually see growth opportunity in Connecticut,” McCarthy said. “As we go through and look at the Connecticut property, one of the things that have been a recent development from a technology perspective allows us to serve lower density parts of the state of Connecticut with U-verse product that was limited by densities and loop lengths in the past.”

Although the company often touts millions in upgrade investments, most legacy service areas see only modest service improvements, while the company continues to score very poor in customer satisfaction, especially in states like West Virginia, Ohio, Pennsylvania and New York. With Frontier’s ongoing focus on newly acquired service areas, long-standing customers in other states are feeling neglected.

In upstate New York, the prevalence of Frontier Communications’ low speed DSL on the company’s legacy copper network has dragged down overall broadband speed ratings to some of the lowest in the country. Frontier territory Rochester, N.Y., in particular, is now among the worst cities in the northeast for overall broadband speed performance, now rated at just 21.42Mbps. The national average is 36.22Mbps. In comparison, Buffalo scores 24.31Mbps, Cleveland: 22.57Mbps, and NYC 55.56Mbps.
