No More POTS!

No More POTS!A.G. Bell‘s question to Watson over a century ago may be relevant again. Tom Nolle at No Jitter explains how that can happen if the FCC expedites the transition to VoIP. Mr. Nolle, the founder of CIMI Corporation does not think that the basic quality of voice service is at risk. He does believe but there are some truly profound consequences to a decision to abandon TDM voice. He believes it will happen, it’s smart to think about the end of POTS — as relates to both opportunities and risks.

70% of business voice is still TDMTelecommunications has long been more than analog voice and copper loops. The author points out that regulations have stayed in the “TDM” Dark Ages. Operators like AT&T (T) have demanded the FCC modernize things. To deal with these issues, the FCC bundled its transitions (TDM-to-VoIP, fixed to mobile, copper to fiber) into a single Technology Transition Policy Task Force. The recommendations from that activity will hopefully launch experiments in promoting change while controlling the risk of unfavorable impacts. The recommendations of the TTPTF (quite the acronym!) are posted online (PDF) and he says it’s a clarion call for change. So instead of talking about the process, let’s look at the impact.

Who still uses TDM

Mr. Nolle the CIMI principal consultant estimates, that 40% of US households still have TDM voice. Businesses have a higher TDM commitment. The article says that nearly 70% of business voice is still TDM. Suppose we saw TDM voice go away completely; what would happen?

Transition access lines and trunks to EthernetFirst, little besides voice that requires TDM services and trunks. Which he says means we would see all access lines and trunks transition to packet–almost certainly to Ethernet. The author says this could increase the number of Ethernet business connections by about 28%. it would also likely increase the access bandwidth commitments by branch offices and SMBs (using DSL, fiber, cable, etc.) by over 50%. Metro and access vendors would benefit from this almost immediately because it’s likely that operators would start to promote Ethernet access and IP voice more strongly as soon as the “experiments” showed signs of success.

Operators already like the notion of an “access-first” strategy where they supply a fat pipe to a customer and then build ad hoc services over it. Ethernet or packet access encourages that, so giving that to everyone would drive operators quickly to look for rapid service deployment tools so that they don’t lose all the new access-generated opportunities to the over-the-top players (OTTs). The author believes that operator interest in software defined networks (SDN) and network functions virtualization (NFV) are linked to this very thing. After all it’s silly to talk about “improved service velocity” if you have to restring an access connection to upgrade service.

Impact on Internet policy

Net neutrailityThe second impact Mr. Nolle sees is on Internet policy. This voice transition raises the question of the difference between “packet” or “IP” and “the Internet”. You can do VoIP over any IP, including private networking. That’s done with a lot of IP voice today in fact. Operators could in theory augment their services to customers by building IP services that bypass the Internet, but that would pose issues in linking the services to current devices in the home or in businesses. OTTs would surely want to get involved in any new service opportunity, and all that raises the triple-threat question of QoS, settlement, and Net Neutrality.

There’s no barrier to QoS in “private” IP networks, but on the Internet, the Net Neutrality order last year said that you could offer QoS only if the subscriber pays for it. Most practical Internet QoS opportunities arise because an OTT like Netflix (NFLX) could gain by offering QoS to customers. They’d pay the ISPs and either embed the cost or perhaps eat it to improve their differentiation. But the FCC said “No!” Now the new FCC Chairman, Tom Wheeler, says “Perhaps”–at least he did in a speech to a university audience. If that were to become policy, it would likely drive QoS for Internet services, and that would drive settlement among ISPs and content players.

QoS stops where the ISP hands off the trafficSettlement has been a big issue for the Internet since the 1990s. Customers pay their own ISP, so if there’s no money flow from that ISP to others, QoS stops where the ISP hands off the traffic. That’s inhibited the value of the Internet for applications that need QoS, but it perhaps encouraged smaller players and startups who couldn’t pay like Google (GOOG) or Netflix could. Whether this small-player benefit is more for VCs who then have to raise less funding to get an OTT off the ground is an interesting question–but in any event, adding settlement and QoS to the Internet would almost certainly increase operator interest in providing service quality for a fee, which in turn would increase network investment, helping equipment vendors and carriers alike… In short, it would change the industry.

Mr. Nolle concludes that VoIP could be a back door to making the Internet a real network and not a service on top of carrier IP infrastructure. That could remake our experiences online, and the vendors’ fortunes in the marketplace. So watch the progress of this initiative; it could have huge impacts.

ATT has already made its move to get rid of POTS lines in Michigan. ATT has bribed gotten politicians in Lansing to introduce Senate Bill 636. Michigan SB 636 would amend the Michigan Telecommunications Act (PDF) to let ATT and their fellow travelers eliminate POTS lines in Michigan.

Melissa Seifert, associate state director for government affairs for AARP Michigan says eliminating POTS lines in the Great Lakes State would impact many people. It would affect small-business owners who use fax machines and credit card verification systems, she said, as well as emergency services in parts of the state where cell phone access is unreliable. According to the Michigan Public Service Commission, roughly 3 million Michiganders subscribe to landline service. About 90 percent of households of folks ages 65 and older still use landlines for “lifelines.”

iPad Driving Wireless Networks

iPad Driving Wireless NetworksJuniper (JNPR) recently loosened up its purse-strings and bought Trapeeze Networks to fill the most obvious hole in its product line. Juniper purchased the WLAN vendor from Belden (BDC) for $152 million in cash. The Belden/Trapeeze relationship is something I never got, when I think Belden, I think cable, and connectors not wireless. NetworkWorld cites Gartner “…more than 60% of end-users purchased their WLAN solutions from the same vendors as their wired LANs, meaning that Juniper has likely been leaving a lot of opportunity on the table.”

David Yen, executive vice president, and general manager, Fabric and Switching Technologies, at Juniper (and owner of possibly the longest title in networking), told NetworkWorld that the industry is much more mobile, “it was time for us to include wireless.” GigaOm says that the purchase was a recognition by Juniper that the enterprise networks were going through a sea change, thanks in part because of a big upsurge in the number of mobile devices connecting to corporate networks. This proposition is backed up by a survey by BoxTone Mobile Service Management which found that 73% of the surveyed companies intend on deploying the Apple (AAPL) iPad as well as other iOS devices for use on their network within the next 12 months, with 25% of those companies set to deploy right away. More than 50% of those surveyed plan on deploying their own iPad app within the next 12 months, while 25% of those plan on deploying as many as three of their own iPad apps.

IT executives interviewed by WindowsITPro.com argue that the iPad isn’t for everyone, but is very well suited for users that consume more content than they produce, such as, e-mail and corporate documents. Another area where the iPad seems to be making inroads into corporate IT is as a device that displays content for cloud and software as a service (SaaS) business solutions.

Some of the iPad initiatives include:

  • Mercedes-Benz is using iPads on showroom floors according to ZDNET. MB uses the iPad to present and execute the various financing options for customers without having to go sit down in an office.
  • SAP the world’s largest business software developer has released an iPad app so that its customers can access their reports and corporate data with the iPad. ZDNET reports that SAP is also using and supporting iPads internally. Rob Enslin, the North American president at SAP, says that he now carries an iPad instead of a laptop when he travels. “It’s allowed me to almost run a paperless office,” said Mr. Enslin. He said that he uses the iPad to view business apps, briefing documents, customer information, and other corporate data.
  • ServiceMax has developed an iPad app for pushing the device as a modern solution for field service applications according to WindowsITPro.com
  • Rackspace has developed a configuration management tool for cloud data centers according to TechWorld

Dominic Orr, CEO of Aruba Networks (ARUN), told GigaOm that his firm expects to see future demand coming from corporations who are seeing a big shift in the way their networks are being used. “The network model has shifted from hotspots to ubiquitous and uniform networks access,” Orr said. Companies now want wireless access not only in boardrooms and hubs of productivity but also in stairwells, corridors, kitchens, and other areas. Why? Because the devices accessing the network are entirely different, he pointed out. “Our demand is being driven by smartphones and smartpads,” he said. In the past, laptops were used for wireless access, but it was difficult to walk around and use them as easily one can use a smartphone or an iPad. The smart devices, however, encourage anywhere computing, which, in turn, puts a different load on the networks.

Mr. Orr goes on to say that iPads and tablets are very multimedia-centric, which means folks are looking for good, solid, and even coverage across their entire campus, and not just in certain specific areas, Mr. Orr pointed out. “While netbooks and laptops have wired Ethernet built into them, the new smart devices can only access the Internet via mobile connections,” he added. “You either have 3G or Wi-Fi.” These demands for improved coverage have led the research firm Dell’Oro Group to estimates that the enterprise WLAN market will grow from $2.2 billion in 2010 to $3.4 billion in 2014.

The iPad, and many new and emerging consumer devices, only have Wi-Fi connections network teams are going to face many challenges in the face of iPad adoption. Wi-Fi networks are viewed as a utility by employees, who expect to connect any device to any network to get connected. Underscoring a major societal and cultural trend of the connected lifestyle, Enterprise adoption of the iPad is part of the larger trend of consumerization of IT (which I have written about here, here, and here) in which companies are allowing employees to choose which tools they use.  The negative consequences of not allowing users to choose the products they want to use themselves simply aren’t worth it, according to Karl Ageberg, CIO at Lund University in a PCWorld article. That movement will also open the door to competing products from a growing number of Android-based tablets and Research In Motion’s upcoming PlayBook.

Some of the ways  iPads will force changes:

  • Internal IT security to deliver secure access methods for all consumer devices in general.
  • Security policy changes, to offer secure and controlled access to corporate data.
  • Network and application security design, to provide secure and controlled access to corporate data.
  • Network management to make sure mission-critical devices and applications get the required QoS and SLA required.
  • Mobile device management platforms ability to control access and storage of sensitive corporate data on these devices.
  • Support for consumer devices, owned both by the organization or by individuals.
