So Long T1 and POTS, Hello AI

By: John Shepler

Have you gotten the word from your telecom service provider that your T1 lines and POTS telephone lines are scheduled for decommissioning? Perhaps you’ve seen news items to this effect. It’s true. The major landline telephone companies are determined to replace their more than a century old copper cables with the newer technologies of fiber and wireless. It’s happening faster in some parts of the country than others. Like the incandescent light bulbs of the same era, copper telco connections are being relegated to history.

Why Do They Hate Copper?
Copper has served us well from the gilded age to this millennium. Copper POTS phone lines are highly reliable and are powered by the phone company. If you lose power, the phone still works because the equipment has battery backup at the central office. If you want the same functionality with your VoIP phones on the Internet, you’ll need add that battery backup at your end.

Copper T1 lines have been the mainstay of both business Internet connections and PBX phone systems for decades. Some companies use them for direct connection from one business location to another. As private lines, they are more secure than the Internet and you avoid the congestion when everyone in the area is trying to work online at the same time.

Like all legacy technology, T1 and POTS lines are getting a little long in the tooth. A T1 bandwidth of 1.5 Mbps was once considered broadband. Now 1.5 Gbps has the same respect. Analog POTS lines and their own unique telephone network are being replaced by LAN and WAN network connected phone systems, often with switching systems in the cloud. As a result, there are fewer and fewer users of these older circuits. Most consumers are primarily dependent on their cell phones and have dropped landline phone. Businesses are heading more and more to the cloud and using fiber optic direct connections to get there.

This is creating quite a dilemma for the phone companies. The incumbent local carriers own all that copper and it is not getting any younger. Fewer customers means less revenue. Corroding wires and insulation result in more any more repair calls. The cost of maintaining that copper plant keeps going up and up.

Copper’s Replacements Are Mostly In-Place
The replacement for all that copper interconnection is fiber and wireless. Fiber has the advantage of nearly unlimited bandwidth. With wavelengths and multiple strands per cable, there is lots of unused capacity that can be pressed into service as data demands increase. The limitation to date has been too few routes installed and lit for service. That’s changing fast. Many cities have seen the future and are contracting for municipal fiber that runs past every home and business. Cellular 5G and eventually 6G require fiber to get the required bandwidths.

The other replacement technology is wireless. The same 5G towers used for phone calls also support fast broadband in the dozens or hundreds of Mbps. Mobile Internet nearly everywhere is already in place. A newer wrinkle is a 5G access point, essentially a phone without the user interface, that installs in a home or business. You have broadband Internet service that is always-on and you don’t need to worry about connecting to a fiber or cable.

There are still dead spots. Sparsely connected areas may not have fiber, cable or cellular coverage. They mostly did have landline phones, though. The replacement for these areas may be GEO or LEO satellite, as they may never get cell towers or fiber lines.

What Becomes of The Copper Facilities?
Oddly enough, the latest technology may provide a new lease on life for the oldest. One proposal is to gut those telco central offices and points of presence and install high powered servers to support the demand for Artificial Intelligence.

The facilities with utility power, battery and generator backup, HVAC, and weatherproof buildings are already in place. By upscaling them to be small data centers located near potential customers, the growing demand for AI services can be supported faster than with all new construction. Another major benefit is the lower latency that comes with having computing at the network edge rather than centralized thousands of miles away.

The copper itself may well be mined to support the need for electrical transmission, electric vehicle propulsion, power generation and more. Some copper cables are pulled out of their conduits as fiber is installed to make room for the new fiber. Copper in the ground and central office wiring may become a welcome source of recycling, much as scrap aluminum is melted down and repurposed. No point in letting it corrode to dust if it costs less to reuse than smelt new ore.

AI Is Going to Eat Your Bandwidth

By: John Shepler

We may be nearing the end of the age of person to person communications, or at least human communication dominating the use of telecom resources. The decline began when computers started using our phone lines to exchange data. It’s only accelerated since nearly all computers are now connected to the Internet at broadband speeds. Even so, much of that computer activity is in the service of people accessing websites, messaging and sending email, posting on social media, watching videos, backing up their files and doing their jobs. Not for long. Pretty soon machines will cut us out of the loop and simply talk among themselves.

The Rise of Artificial Intelligence
The scary thing about artificial intelligence, or AI, is how insidious it is. It’s actually been creeping in for decades, probably since the start of the computer age. There’s a lot of AI in search engines, although we may not think of it that way. Most software, in fact, has been adding analytical and decision making capability deep under the hood. You may not be specifically asked your preferences, but that doesn’t mean the program isn’t figuring things out or selecting what information to display and how.

More recently we’ve seen an explosion of “chat bots”, intelligent assistants such as Siri and Alexa, and some quirky writing and photo capabilities in ChatGPT. In fact, it’s the last one that has fueled an explosion of interest and investment in what is called Generative AI, the tech that “creates” all that new content at the push of a button.

NVIDIA can’t make big enough processors on a large enough scale to sate the demand. Data centers are expanding to host more and more servers and new centers are rapidly under construction. One big worry is where all the energy is going to come from to feed the exponentially demanding power-hungry AI processes. Some data centers are being built right next to power plants to grab and many megawatts as they can.

How Nuts is This Going to Get?
One might suspect that we’re in an AI mania combined with a speculative bubble in anticipation that artificial intelligence will render pitiful human capabilities and their jobs obsolete in the matter of a few years… or less. The computer age has certainly eliminated or greatly reduced some roles, like telephone operators and adding machine clerks (human computers), but added new ones as fast or faster. The new AI fever sees the elimination of writers, graphic artists, analysts, software coders, customer service representatives and even law clerks as imminent.

Not so fast. The chat bots I’ve dealt with are complete simpletons that can’t solve much of any real problem. The writing is tedious. The artwork is artificial at best, and inane at worst (how many extra fingers can you add to a person’s hand?). Self driving trucks? Look out when they come barreling around a curve during an ice storm.

I suspect the AI crazy has hyped up expectations far beyond what is really going to work anytime soon. However, that doesn’t mean there isn’t a real germ of innovation underway. One example is the “Internet of Things” that is being touted as the real driver of 5G wireless. Better, faster, cheaper and smaller electronics makes it possible to add both processing and communications to any device. That can be any tool, any monitor, any control system, and most products. It is only logical that these “things” will communicate with other “things”, including computer systems, without our constant knowledge or intervention. The more of these “robots” that are deployed, the more sophisticated the software needed to keep them employed efficiently.

What to Likely Expect
Yes, technology marches on in the name of progress. We’re not going back to living in mud huts or slaving in dingy factories, and the nature of what we do at work will continue to evolve. The increase in productivity should improve our standard of living if we’re smart about it as a society. At any rate, the demands on technical infrastructure are surely going to accelerate.

You can expect more devices on every network, talking faster and demanding faster results. The “cloud” may become an “overcast.” Both fiber optic and wireless bandwidth requirements will move up another order of magnitude or more. A 100 Mbps connection may have been plenty not long ago. Now we clamor for a Gigabit line, with 10 Gbps an emerging business standard. How long before 100 Gbps is routine and 1 Tbps starts looking like a requirement? Within the data center, this could be tomorrow. For access, maybe the day after tomorrow.

How about your business? Are new tools, processes and devices straining the capability of your data center or WAN network? We can help. Get pricing and support on bandwidth and hosting for your current and future needs right now, before those needs become a crisis.

Cost Saving Shared Fiber, Wireless and Coax

By: John Shepler

You need connectivity but are feeling the pinch of inflation. Is there any way to get a business online and not break the bank? Sure there is. If they work for you, shared bandwidth wireless, cable coax and fiber optic connections are available at bargain prices. Let’s have a look at these.

What is Shared Bandwidth?
You are probably too young to remember telephone party lines, but how about roommates at school? That’s the sharing economy. It’s based on the idea that if something is expensive you can still have it as long as you join with others to foot the bill.

Internet connections can be had the same way. A fully dedicated high speed symmetrical fiber optic link can run into the big bucks every month. If that’s what you must have, then you’ll just have to come up with the lease fee. But, if your usage isn’t all that demanding, you can probably share the line with others, not limited to users within your company, to split the cost.

Now, this is where shared bandwidth services differ from the old party lines. Back in the day, a single analog phone line would serve multiple households in the same area. When you picked up the handset, you might hear a dial tone or you might hear someone else’s conversation already in progress.

The polite thing to do was hang up and wait awhile before you tried again. More often that not, curious individuals would simply cover the mouthpiece and eavesdrop on the call.

Shared bandwidth isn’t really like that… for the most part. You and another customer aren’t going to see each other’s traffic on your screen. The routing in the system keeps your data streams separate. However, all your bits are intermingled on the same line. A clever hacker can figure out how to monitor whatever traffic they can access.

The way around that limitation is encryption. Encrypt all your traffic and you’ve created a secure tunnel through the public Internet. That’s critical for using WiFi hotspots, but important for any shared access or easily tapped-into connection. Most websites and email services have gone to secure connections that are encrypted, but all your file transfers should also have this layer of security.

Shared Bandwidth Via Coax
Cable broadband is the originator of the coaxial copper connection. This standard was originally designed for analog cable TV and community antennas. Eventually a cable connector came standard on the back of TV sets. Later, Cable providers became Internet Service Providers by developing a modem that could connect to their coaxial line and share the bandwidth between TV and Internet.

The modem technology that does this is called DOCSIS for Data Over Cable Service Interface Specification. The most common version is 3.1, which is capable of multiple Gigabits on the downline side. The newest is 4.0, which can support 10 Gbps downstream and 6 Gbps upstream.

Shared Bandwidth Via Wireless
Smartphones have had excellent Internet service starting with 3G and 4G LTE. The small screen requirements are easily supported and were quite useful even with the old 2G standard. The standards also serve tablet computers, laptops and in some cases desktop computers, especially when other ISPs are offline. The bandwidth is often enough from a shared smartphone connection. The one limitation for desktop usage is that you might run up against monthly data limits.

With 5G service, cellular providers have begun promoting the use of their Internet service at fixed locations. They even have a name for this: Fixed Wireless Access. Instead of sharing your phone with your desktop, you buy a 5G gateway that may offer an Ethernet port for your network or WiFi hotspot. It connects to the provider like a phone, but without the mobility or voice service. There is simply an incremental charge to your cellphone bill each month. If you have good signal strength, you may get bandwidth of a hundred or two hundred Mbps without a wired connection.

Shared Bandwidth Via Fiber
Fiber optic service used to be only for major corporations and priced accordingly. Now fiber is so widespread that you can get Ethernet over Fiber Dedicated Internet Access in most reasonably populated areas. Bandwidths are available from 10 Mbps up to 10 Gbps and even 100 Gbps in major metro locations.

Fiber Internet is highly desirable and prices have dropped dramatically over the years. Even so, you may still want a lower cost option. Did you know that you can still have fiber for a bargain price? The technology involved is called PON or Passive Optical Networking. The provider takes that high bandwidth dedicated fiber line and divvies it up among 32 users using a passive splitter. Each customer still gets a fiber line, but the bandwidth on that line is being shared among multiple users just like cable broadband. In fact, cable companies are pioneers in building out this technology. You get fiber bandwidths, but with pricing that is more similar to cable services.

Limitations of Shared Bandwidth
While you won’t be seeing your neighbors messages popping up on your screen, you will likely still feel the effects of sharing. During periods of heavy usage, the service slows down. You might even detect congestion that brings everything to a crawl and then, just like with traffic jams, magically disappears. VoIP phone calls can break up. Video conferences can stutter or freeze. Cloud applications can become sluggish.

Another characteristic of shared bandwidth connections is that they are usually asymmetrical. That means that the download speed is much higher than the upload speed. Typically, a factor of ten or so. For Internet browsing or email, this may make no difference. It could impact video conferences and large file transfers up to cloud storage.

You can improve on this with a dedicated Internet access or with a software defined wide area network or SD-WAN. This is a technique for combining multiple Internet connections. The SD-WAN controller assigns traffic to the most appropriate link, with sensitive applications like phone calls getting the highest priority on the fastest paths. SD-WAN can let you combine a fast shared and low cost line with a small dedicated line. The result can be a service that gives you all the performance you need at a lower cost than a high speed dedicated fiber line.

Gigabit WiFi For Video Streaming

WiFi hotspots, routers and access points have been deployed to such an extent that WiFi really is the default wireless connection. Bluetooth range is way too short. WiMax never deployed far enough, wide enough or fast enough. Cellular 3G and 4G are only valuable when you are away from WiFi access, since bandwidth is limited and overages are painful. Recent reports show that most tablets never use the built-in 3G wireless. WiFi is a replacement for cellular broadband, but it’s also becoming a replacement for wires.

Think about it. How much trouble and how expensive is it to string Ethernet cables through a home or office? Most people don’t have the skill or determination to snake wires through the walls of their two story home and don’t dare to try to wire an apartment. That means you are stuck with being in the same room as your DSL or Cable modem. Inexpensive WiFi routers got rid of that cable limitation. Now many PCs and printers come with WiFi access so that you can place them anywhere you want.

The other big tether is the television coax or HDMI cable. If you want to connect video, you have to string wires. The standard means for that has been RG-6 or RG-59 coax. But HD outputs are now HDMI, so your old coax is limited to SD video. That’s assuming you were able to get coax installed in every room you wanted.

Complicating matters now is that traditional video sources, such as satellite and DVD, are merging with the Internet. Many TVs, Blu-ray players and games now come with Ethernet jacks. You still need an Ethernet cable, but now it’s for video broadband not just web browsing. Or... do you?

Video is a need screaming for a wireless solution. The legacy WiFi 802.11b&g versions clearly are not up to the task. WiFi 802.11n does much better, but has trouble finding a clear path through the crowded 2.4 GHz ISM band. It's also pressed for enough bandwidth to support all things video. The solution? It’s an enhancement to WiFi-N called WiFi 802.11ac.

What’s better about WiFi-AC compared to WiFi-N? Most importantly, it pushes wireless bandwidth above the Gbps level. Total capacity of an 8 antenna system will reach almost 7 Gbps when this technology is fully developed. That should be enough to keep up with the rapid advancement of HD and 3D streaming video devices and become the way to eliminate Ethernet, HDMI and coaxial cabling in the home and office.

How does 802.11ac achieve this performance? First of all, it completely abandons the crowded 2.4 GHz band and uses the lesser populated 5 GHz band exclusively. That cuts out a lot of interference. Next, the transmission channels are widened to achieve more data carrying capacity. Channels are 40 MHz maximum in 802.11n. These are expanded to 80 MHz minimum and 160 MHz optional for the new standard.

WiFi-N introduced MIMO or Multiple Input Multiple Output antenna technology. MIMO is a way for transmitters and receivers to deal with scattering radio waves and interference by intelligently analyzing the received signals to determine which ones are valid. It’s a little like being able to tell which direction a sound originates by using two ears rather than one. Beamforming compensates for phase shift of multiple received signals to increase the total signal level. This allows higher bandwidth over a longer range.

A more complex modulation scheme is being introduced in 802.11ac called 256 QAM. The term QAM refers to Quadrature Amplitude Modulation. It uses both amplitude and phase shift to send data over two combined carriers differing by 90 degrees, called quadrature. Each combination of phase and amplitude represents one digital number. 802.11n used 64 QAM to send 6 bits per symbol. 256 QAM sends 8 bits per symbol, a third more efficient in use of the spectrum.

When will be see 802.11ac equipment on the market? Probably near the end of this year or the beginning of next. Broadcom recently announced the first chipset to support the protocol. They are dubbing it “5G WiFi” to emphasize the considerably higher performance from previous wireless standards, similar to how cellular carriers use 2G, 3G and 4G to describe their generations of technology.
