Ethernet over Copper Is The New Telephone Line

Twisted pair copper has been the standard way to connect telephone service for over 100 years. Guess what the latest in telephone line technology is? Why, it’s twisted pair copper!

Time to upgrade your old phone service? Get Voice over EoC prices and availability.You might see this as an example of “everything old is new again,” but this technology is a twist on the old twisted pair. While analog signals defined telephony in its first century, digital will rule the next century. What remains the same is the actual physical copper wireline.

Why does this make sense in an age of fiber optic communications? It’s a matter of economics. If we were made out of money, the thing to do would be to rip up all that copper in the ground and replace it with unlimited bandwidth glass fibers. But we’re not made of money and it turns out that voice-grade copper line has far more capability that we ever thought possible.

When we think of the copper phone wires that come into our homes and businesses, we think of telephone handsets for talking and 56 Kbps modems for our computers. That was last century’s technology. By switching from analog to digital transmission, you can have business grade telephone service and broadband up to 20 Mbps on those same copper phone lines.

How is this different from DSL? DSL is actually a hybrid of analog telephony with digital data sharing the same line at frequencies beyond the range of human hearing. It’s a way for residential and small business users to add broadband Internet service to their existing phone line. As a "best effort" information service, DSL was designed to optimize cost and has some well known performance and availability issues.

This is something different. It is based on Ethernet over Copper technology that bonds multiple dry copper pair to deliver a highly reliable and solid bandwidth all-digital signal to business locations only. It’s not a residential service. It’s intended for businesses that require a robust voice and data service similar to what they may be getting from an Integrated T1 line.

TelePacific, a major competitive carrier serving California and Nevada, calls their service SmartVoice. It’s an enterprise VoIP telephone service using SIP signaling. This voice service is combined with either dedicated broadband Internet access or MPLS network service. You would choose broadband to have both telephone and Internet brought in on the same line. You’d choose MPLS to link multiple business locations for both telephone and data exchange.

TelePacific maintains high voice quality by dynamically integrating the voice and data traffic on the line. Lower grade VoIP services simply use a broadband line for both telephone and computers. When data traffic gets high, voice quality suffers and calls can even be dropped. Dynamic line service actively manages packet priority so that telephone calls have priority and get the bandwidth they need for best operation. The remaining line bandwidth is assigned to data transmission. You are far less likely to notice or be annoyed by small variation in data rates than garbled and broken conversations. Once a phone call is finished, the bandwidth it had been using is reassigned automatically to the bandwidth pool for data. That’s the dynamic aspect to the technology.

What advantages does Ethernet over Copper have over the older Integrated T1 line service? Lower cost is one big advantage. EoC is lower in cost and offers more bandwidth options. You can typically get 1 to 20 Mbps bandwidth with EoC. T1 lines are fixed at 1.5 Mbps, although they can be bonded to deliver higher speeds.

The Case For Telecom Copper

There is a move afoot by some of the largest telephone companies to decommission or get rid of their copper wire assets. Some of this is an attempt to foil competition. Some is simply a technology upgrade as fiber optic cables move in to replace century-old twisted pair copper bundles. Should the FCC embrace the retirement of the copper assets already in the ground and strung on poles, or is this copper a national treasure that needs to be preserved?

Copper based telecom services offer bandwidth and cost advantages.It may seem odd to think of copper as a national treasure. We tend to think of gold and silver when it comes to treasure. But this copper has very high value. You might say it is worth its weight in gold. That value, above the intrinsic value of the metal, is the from the time, effort and cost of stringing the copper wire from user to provider. The telephone companies, protected by a mandated monopoly for nearly a century, are the ones that made this investment and reaped the rewards. But that government monopoly was, in a sense, an investment by all of us to get that copper installed.

Now, in the 21st century, there are copper wire telecom cables running into nearly every home and business. They range from a couple of twisted pair for residences to dozens of pairs in large binder cables running into the back rooms of businesses. The fact that all this copper is in place and all conforms to a set of standards offers the opportunity to press it into service for more than just plain old analog telephony.

Indeed, the telephone companies themselves were first to use two copper pair to deliver T1 line and ISDN PRI services. T1 is most often used to provided dedicated broadband Internet access or point to point connections between two business locations. ISDN PRI carries 23 separate telephone conversations plus Caller ID and is popular for PBX telephone systems.

In recent years, competitive service providers have entered the telecom marketplace to compete with the incumbent local phone companies. The incumbents have an advantage in that they are the legal owners of the copper that runs from their offices to the residence or building being serviced. That’s called the local loop or last mile connection. Competitors have to lease the local loop from the incumbent telco. Of course, they could choose to bring in their own copper cables, but that would be cost prohibitive.

Savvy competitors have also figured out how to just lease the copper wires themselves, with no signals at all from the phone company. They then use newer terminal equipment to send non-traditonal format digital signals down the line. The most popular of these is Ethernet over Copper service. EoC offers higher bandwidths at lower costs than traditional telco services such as T1 or DS3.

Perhaps this is what’s stuck in the incumbent telephone company’s craw. Some meet the competition head to head and offer their own Ethernet over Copper services. Others figure the way to get rid of the competition is to get rid of the copper.

That’s just plain wrong. Until the government has enough stimulus money to fund universal fiber optic service the way that universal telephone service was mandated, taking copper options off the market only hurts the business community. It’s an especially bad move during a time of economic recession when most companies need the highest bandwidth they can get at the lowest cost. In another hundred years, hopefully a fraction of that, the entire interconnection infrastructure will have been upgraded to fiber optics or perhaps something even more advanced. But until that time there is no justification for retiring perfectly good copper wiring that has already been bought and paid for. Better to list it in a register of historic technologies and make sure that it is protected from degradation until no longer needed.

Could your company benefit from lower cost copper or fiber bandwidth options? Check prices and availability for your location. You may be surprised by how much you can save.

Plain Old Telephone Service For Business

What’s the modern way to get business phone service? How about POTS? That’s Plain Old Telephone Service.

Wait a second. Who wants something that’s considered “plain” and even “old”?

You do. That’s who. Why? Because POTS can be the highest quality most cost effective phone service you can get, that’s why. How can that be? Let’s see.

POTS is actually an industry term for analog telephone service over twisted pair copper wiring. It’s the direct descendent of the very telephone that Alexander Graham Bell invented. The Bell name lived on in the form of the Bell Telephone System, which had a monopoly on residential and business telephone service for about 100 years.

Why does that matter in this high technology age? Simply because 100 years is a lot of time to get it right. That’s what the telephone industry did. They got very, very efficient at building, installing and maintaining standardized telephony equipment to meet a strict set of specifications. By the time POTS technology was starting to feel competition, there were standard copper phone cables run to every home and business.

One advantage of analog phone service is that you have a dedicated pair of phone wires from your location right back to the telephone company’s central office. There’s no sharing of capacity the way there is on the Internet, for instance. Thus, phone calls have a predictable sound quality to them. As long as your lines aren’t defective, you have clear understandable voice conversations across town or across the country, even the world. Being a full duplex system, both parties can talk at the same time and be heard. You won’t cut off the start of the other conversation if you respond too quickly. Their voice won’t morph into the sound of Darth Vader or a deep sea diver because the transmission lines are congested.

You have your private space and that’s that. This is why the standard phone system is also called the PSTN or Public Switched Telephone Network. There are actual physical switches in place to create a unique private circuit between you and anyone you care to speak with, regardless of where they are located.

That’s landline phone service for you. Cellular wireless phones may often be more convenient, but they depend on radio transmissions that can vary in strength from location to location. VoIP can sound as good as analog, but often doesn’t because the underlying data network is trying to send too many voice, data and video packets down the line at the same time. The Internet is a particular example of where you get strange and varying results when you use it to carry telephone conversations.

What type of companies does POTS work best for? Small and medium size businesses who need anywhere from a single phone line up to a dozen lines. You can order your lines one at a time as your business grows to need more. With more than 4 lines, you probably have a Key telephone system or small PBX telephone system to share the outside lines among all your employees.

At somewhere around 10 or 12 analog lines, it makes sense to move up to ISDN PRI, also called T1 PRI, digital telephone service. Strict telephone standards multiplex up to 23 phone lines plus Caller ID and switching signals onto a private T1 line. You get the same quality and features you enjoy with your analog service, but the pricing is often lower for ISDN PRI.

What phone service is best for your business? That depends on whether you are an independent sales professional, a high volume call center, a grocery store, an engineering firm or any of thousands of other businesses that depend on reliable telephone service. Our Telarus business consultants can help you get the most cost effective solution that gives you the quality, reliability and features you need. Get Lower Cost Business Phone Service Quotes today.
