Ethernet over Copper Data Service

Traditional data service connections include T1 lines, DS3 bandwidth, OC-3 and higher level SONET fiber optic technologies. Frame Relay and MPLS networks provide nation-wide and international connectivity. So, why use Ethernet over Copper?

EoC or Ethernet over Copper is a fairly recent last mile connection technology. You don’t find coast to coast EoC being offered. If you do, it is probably implemented as a short hop to the central office, IP-based MPLS networking or Carrier Ethernet over fiber for the long haul, and then another short EoC link at the destination.

What Ethernet over Copper offers is a low cost, high performance solution to connect your business location to a larger private network or public network, such as the Internet. EoC offers the advantage of being able to repurpose existing twisted pair copper infrastructure to avoid the high cost of new fiber optic construction or line of sight limitations with high bandwidth fixed wireless solutions.

What kind of bandwidth can you expect? Low speed Ethernet lines at 2x2 Mbps or 3x3 Mbps are good replacements for T1 lines. These services are typically priced the same as a T1 line but offer higher bandwidth for the money. There are higher bandwidths available, from 5 Mbps on up to 200 Mbps.

The 2x2 designation indicates that this is a symmetrical line service. The bandwidth is 2 Mbps in both the upload and download directions. Similarly, 3x3 Mbps means 3 Mbps upload and 3 Mbps download. This differentiates Ethernet over Copper from services like DSL and Cable, which are asymmetrical. In other words, those services offer much higher download speed than upload speeds. For simple email or Web browsing activities, this isn’t critical. But if you are uploading large files or images, accessing cloud services, or managing a remote server, upload speed becomes much more important.

What is Ethernet over Copper? It differs from traditional telco-based services in that the native protocol is Ethernet rather than TDM or SONET. Ethernet has become the standard LAN protocol and the most common interface to nearly all computers and network equipment. With EoC, you connect to the network using a standard RJ-45 Ethernet connector. That’s it. There are no special interface or conversion circuit cards required.

Ethernet over Copper uses dry or unpowered local loop connections from your location to the nearest telco central office. This is standard telephone wire that isn’t being used for any other purpose. Nearly all businesses have multi-line cables with multiple twisted pairs already installed. Most of the time there are numerous spare wires in that bundle. EoC equipment uses two or more of those spare pairs to transport digital data as Ethernet packets.

The one limitation of Ethernet over Copper technology is that the bandwidth it can carry depends on distance between the EoC equipment at the central office and similar equipment at your location. Within a mile or so, you can generally get all the speed you want at a fraction of what you’ll pay for other telecom services. At you get farther away, the maximum rate decreases due to signal attenuation in the line. More than a few miles and the signal becomes unusable. That may sound like quite a limitation, but in reality most business locations are well within the range of Ethernet over Copper. The exceptions are rural businesses, and offices where the Ethernet termination equipment isn’t installed yet.

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?

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.

Last Mile Connections That Make Sense

Competitive telecom networks have criss-crossed the country and penetrated every metropolitan area. Their modern IP networks, fiber optic bandwidth and dramatically lower prices makes them very attractive to businesses of all sizes. But how do you get connected?

Often, the most important, most expensive and most limiting span of a wide area network is the drop to the customer site. It's widely known as the "last mile" connection. Why last mile? Because that's a typical distance from a business location to the nearest carrier POP or Point of Presence. A POP is equivalent to a telephone company's CO or Central Office. You need a building where the equipment goes that provides a connection or "termination" to the carrier's backbone network. That's the POP.

If you are actually within a mile or even a couple of miles from the nearest POP, you've got options. There are many different ways to span the distance. Traditionally, analog telephone lines and digital T1 service came-in on twisted pair copper bundles that were installed as a matter of course when your building was constructed. They still do. In fact, a T1 line makes a fantastic last mile connection for PBX telephone trunking, VoIP SIP trunking, MPLS multi-point networks, dedicated Internet access and point to point voice and data connections to other locations. T1 lines are highly reliable and can be bonded together to increase bandwidth.

But aren't they pretty expensive? They were at one time. That's why many businesses had to settle for slower 64Kbps and similar connections from their facilities to a much faster Frame Relay network. These days, that's like hooking a soda straw to a fire hose. You can't possibly tap the capability of the core network when you're so bandwidth restricted.

Fortunately, T1 lines cost only a fraction of what they did a few years ago. Just in time, too. You need at least 1.5 Mbps for many business applications and multiple line telephone systems. The copper pairs that transport T1 service can also be reconfigured to carry higher bandwidth Ethernet service directly from a carrier POP to your location. Your connection is via a standard Ethernet jack for bandwidths from 5 to 50 Mbps. Once on the network, your connectivity can run across town or across the country, even the world.

If your needs exceed the capability of Ethernet over Copper, you need the big daddy of last mile connections: fiber optics. All the metro and long haul networks are now fiber-based. The bandwidths available go up to a Gbps, called GigE, and even on to 10 Gbps. Prices per Mbps of bandwidth can be half what you're paying for non-Ethernet service now, or even less. But you'll need to have your building "lit" for fiber optic service. Is it already lit and you just don't know it? Find out with this Ethernet service locator.

Are there any other options for last mile connections? Yes, and one of these might be just the right service at the right price. In some major cities you can get wireless delivery up to 45 Mbps. The trick is that you need to have line of sight to the carrier's transmitting tower. For lower speed applications, like point of sale terminals in small retail locations, wireless connections using cellular broadband works well and is very affordable. At distances of only a few hundred feet to less than a mile, laser optics equipment can "beam" your connection across highways, lakes and other areas where fiber optic construction costs are astronomical.
