Ethernet over Copper and Ethernet over Fiber are the hot new WAN network connections. They are growing in popularity because of high competition reducing Ethernet prices and services such as layer 2 switching available with direct Ethernet connections. So, why would you want a solution such as Ethernet over DS3?
It sounds like a hybrid arrangement. DS3 is a commonly available telecom service offering 45 Mbps from a T-Carrier standard TDM (Time Division Multiplexing) technology. Most users of DS3 order it for dedicated point to point connections, broadband business access for larger organizations, and high volume telephone trunking in enterprise contact centers and commercial call centers. Why put a new protocol like Ethernet over a legacy protocol like DS3?
The big advantage of Ethernet over DS3 is that it gives you the Ethernet connectivity and services you desire in areas where Metro Ethernet or Carrier Ethernet services are not yet available or too expensive. You may already have DS3 brought into your building. If so, the physical layer already exists to transport any protocol that is compatible with that DS3 service.
Another situation is when SONET fiber runs close to your location and it is quite affordable to demultiplex a DS3 connection and bring a drop to your building. The native Ethernet over Copper and Ethernet over Fiber networks may not have build-outs anywhere near you. While the range of services and pricing from competitive carriers operating their own IP-core networks can be impressive, they may not have a service footprint in your area. DS3 is a more mature transport technology and may well be available to business locations nearby.
What can you expect from Ethernet over DS3? Bandwidth is limited to DS3’s rate of 45 Mbps, although Ethernet services are often very scalable and can be ordered from a few Mbps right on up to the limit of the port speed. If you need higher bandwidth, say 100 Mbps Fast Ethernet or higher, it may be possible to bond DS3 services the way T1 lines are bonded to multiply bandwidth. Also, If DS3 is available it is likely being carried on a SONET fiber optic service, such as OC3 at 155 Mbps. You may be able to get a higher bandwidth connection if there is extra capacity in the fiber service that delivers your DS3.
Is Ethernet over DS3 the right option for your business? The best way to find out is to get a set of competitive quotes for all bandwidth services available at your business location. There may be more options at lower prices than you expect.

Are you ready to move up to the next generation in smartphones? Have a look at the Samsung Captivate for AT&T. It’s fast, it’s bright and it’s Android. In fact, it’s Galaxy Android.
The Samsung Galaxy series is generating a lot of buzz. These phones will go by different names as they are released for each carrier. Captivate is the name of this Galaxy for AT&T’s wireless network. Captivating it is.
Could they make it any thinner? Not with today’s technology. This case measure in at 0.4 inches. Remember when everyone was shocked by the 0.5 inch RAZR? Those razor phones where phenomenal in their day. Today they are as dated as a Commodore PC. Well, maybe technology hasn’t advanced that fast in the last few years, but is sure seems like it. Consider that the Captivate processor is running at 1 GHz, the camera is 5 Megapixels, and the touch screen display measures 4 inches. Does that make your current phone seem dated?
The Samsung Captivate is getting closer to the idea of a computer in the palm of your hand. The Super AMOLED touch display is fast and bright, even outdoors. That makes it able to keep up with the 1 GHz Cortex A8 Hummingbird processor and display the clarity of the 5 MP digital camera. Unlike most cell phone cameras, this one records HD videos. It also has face detection and smile detection, features you’ll find on dedicated digital cameras.
Captivate is designed for work and social networking. It comes preloaded with Google apps such as YouTube, Gmail, Gtalk, Google Voice and Picasa. Swype lets you simply slide your finger over letters to draft a text message. At some point you’ll wonder why you needed a physical keyboard at all. Google Maps is preloaded so you’ll have voice-guided turn by turn directions at your disposal. The Social Hub maintains all of your social networking updates and contacts in one place.
Of course, this you also have access to the Google Android Market where you can choose from thousands of Apps to truly customize your smartphone. Like games? You’ll be able to enjoy games with 3D motion gaming, high fidelity sound and surround sound. There’s a 6-axis motion sensor to give you motion control beyond what you are use to on a phone or even some gaming systems.
How about connectivity. Data download speed is up to 7.2 Mbps on the AT&T 3G network running HSPA. This is also quad band GSM phone that will work with worldwide standards. Network compatibility is 850/900/1800/1900 for GSM and 850/1900/2100 for UMTS. WiFi is also included, so save your minutes when you are in a WiFi hotspot.
Do you feel the need to step up to the latest generation in smartphone technology? Does this sound like the phone you’ve been waiting for? Then wait no more. Learn more and order your Samsung Captivate for AT&T right now at an incredible discounted price online.

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.
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.
