Ethernet over Copper FAQ - Part 2

Ethernet over Copper has become a serious contender for business connectivity solutions traditionally provided by T1 lines, DS3 bandwidth and OC3 fiber. Consider the following FAQ, frequently asked questions and answers, to help you decide if EoC service is right for your business.

Q: What is the cost advantage of EoC versus other line services

A: EoC generally offers a significant cost savings compared to what you are used to paying for business bandwidth services. For instance, a 3 Mbps Ethernet connection is often priced the same as a 1.5 Mbps T1 line. The cost savings are even more pronounced at higher bandwidth levels.

Q: What determines Ethernet over Copper availability?

A: The two major elements are local availability of service and distance from the central office that connects your copper pair cabling. T1, DS3 and OC3 have been around much longer that Ethernet over Copper and are more readily available. Not all offices have the necessary terminal equipment to support EoC. The bandwidth available from Ethernet over Copper technology is much higher close to the central office than farther away. While nearly all business locations can get lower bandwidths if available, the higher bandwidth services may be available over short distances only.

Q: Why is dedicated bandwidth important?

A: Dedicated means that you have exclusive use of the available bandwidth on your line. Consumer oriented line services, such as DSL and Cable are shared bandwidth arrangements where the speed of your connection varies with the activity level of other residential and business users. Dedicated bandwidth ensures that your connection won’t get bogged down just when you need it to be productive.

Q: What is EoDS1 and what is its application?

A: EoDS1 is a hybrid between EoC and T1. It essentially uses T1 lines to transport Ethernet service. This increases the geographical area where Ethernet is available and is generally lower in cost than multiple bonded T1 lines to achieve the same bandwidth.

Q: What is Carrier Ethernet?

A: Carrier Ethernet is the same Ethernet protocol that runs on your company LAN but extended for operation over metropolitan and wide area distances. The standards for this technology have been established by an industry association called the Metro Ethernet Forum or MEF. Carrier Ethernet includes Ethernet over Copper and Ethernet over Fiber.

Q: What special network services are available over Carrier Ethernet?

A: There are 3 services you may find interesting. Ethernet Line service or E-Line is a point to point connection, similar to what you get with T1 and other telecom services. Because the protocol is Ethernet on both the LAN and WAN, you can bridge LANs at two business locations to create one larger business network. E-LAN or Ethernet LAN service is a meshed network arrangement that interconnects 3 or more business locations. E-Tree or Ethernet Tree service is a one to many connection suitable for content distribution.

Q: Is EoC suitable for Internet service?

A: Internet connectivity is one of the more popular ways that EoC is used for business. A dedicated Ethernet Internet connection gives you a highly reliable link from your location to the Internet. EoC bandwidth is symmetrical (the same in both upload and download directions) to support voice, video and cloud services as well as Web browsing and email.

100 x 100 Mbps Business Bandwidth Options

Bandwidth levels of 100 Mbps are no longer a luxury for many businesses. You need that much to backup files remotely, access cloud applications, distribute content and share large files such as high resolution medical images. Traditional bandwidth services like T1 lines or DS3 connections don’t come close to meeting this requirement. What does and can you afford it?

The traditional service that supports this capacity is OC-3 SONET fiber optic bandwidth. Larger companies have used OC-3 for decades. What’s limited the number of companies that install this service has been high costs, at least in past years.

If you haven’t checked prices in a decade or even the last few years, you’re in for a pleasant surprise. OC-3 prices have plunged from the astronomical levels of years ago to something well within reason today. Medium size businesses and medical organizations, and many smaller high tech businesses where high bandwidth is essential, can now afford OC-3 bandwidth... but should they?

Besides the cost reductions for telecom services, something else has happened recently to give businesses options for 100 Mbps bandwidth. It’s the rise of competitive technology. Decades ago, it was OC-3 or nothing at all. Today, that is just one of several services that can get the job done. Let’s take a look at what else is available.

The biggest competition to SONET fiber optic services is now Ethernet over Fiber. The fiber optic pipes are the same. The signal that they are transporting is different. For you as a business owner or IT manager this makes no difference in the end. Both SONET and Ethernet technologies can carry the same traffic from place to place or to and from the Internet. However Ethernet has some advantages you should know about.

The most important is cost. Much of this is due to competition and some to the way networks are constructed. SONET is a telephone company developed technology. There is almost always a telephone company involved in delivering SONET. It might be for the entire span. Often, the last mile is handled by the local telco and the rest is provided by a competitive carrier.

Ethernet is different. Ethernet came out of the computer industry. It had nothing to do with telephones. In fact, Ethernet really gained prominence as a LAN, not a telecom, technology. It still forms the basis of nearly every installed local network. While the traditional local and long distance telephone companies have added Ethernet to their portfolios, other carriers have started up to gain share in this marketplace. Many built their networks around delivering Ethernet services and don’t even offer SONET.

One thing that’s different about Ethernet over Fiber is that the competitive carrier may handle service throughout the entire network. That includes the connection into your building. Multi-tenant office buildings are especially attractive because there is more than one customer to make it worthwhile to construct the fiber drop and termination equipment. Competitive carriers are aggressive about finding and connecting business locations before someone beats them to it. This helps to hold down prices for everyone in the industry... to your advantage.

Another approach to bandwidth delivery is to eliminate the wires altogether. That’s the domain of the microwave wireless companies. If you are in the right location, you may be able to get 100 Mbps bandwidth over a radio beam to a small antenna on your rooftop.

What’s the right location? It’s almost always in the downtown business district of a major metropolitan area. The microwave transmissions are strictly line of sight and limited in distance to a few kilometers. This means that there needs to be nothing but air between your building and the provider’s tower. For financial services companies, corporation headquarters and other downtown locations, this may be no problem at all. If so, you may be able to get the bandwidth you need installed very rapidly with little or no construction cost.

All of these services are also known as symmetrical dedicated bandwidth. OC-3 is actually 155 Mbps. Fast Ethernet is 100 Mbps with many other service levels available. The symmetrical part means that the upload and download speeds are the same. 100 x 100 Mbps means 100 Mbps upload and 100 Mbps download. Dedicated means that the bandwidth is constructed for your use only. Whatever you don’t use sits idle until you do.

Some companies don’t need this level of performance, especially if all they want to do is access the Internet the way you would at home. These companies can save even more money by going with an asymmetrical shared bandwidth service. As example would be a coaxial cable connection that offers up to 100 Mbps download and 10 Mbps upload speeds. Your actual speed at any given time depends on what other users are doing because the bandwidth is in a pool shared by multiple subscribers.

Are you feeling pressed for increased bandwidth but concerned about price and availability? You may have more options than you suspect. Get prices and availability for high bandwidth providers that service your business location.

New York City Internet Infrastructure

When it comes to high bandwidth network services, you would expect New York City to be among the most infrastructure rich places in the world. You’d be right. One key hub in this infrastructure is the network colocation center at 60 Hudson Street in lower Manhattan. This is where Telx operates their flagship carrier hotel and network interconnection facility.

In a recent article in The Atlantic, Ben Mendelsohn discusses his short documentary, Bundled, Buried & Behind Closed Doors, which includes a tour of the Telx facility at 60 Hudson. You can watch it right here and get a fascinating view into the inner workings of network interconnections, like those at the heart of the Internet.



The Telx data center at 60 Hudson is their flagship colocation and interconnection facility. Within the walls of the old Western Union Building, Telx offers low-latency access to more than 400 carriers, financial exchanges, application providers, media and content providers, SaaS providers and other enterprises through a single connection. This is why companies that need high bandwidth, low latency connections choose to colocate at 60 Hudson or in another Telx facility. It’s hard to get much closer to your service provider than to be situated in the same building.

Cross connections are at the heart of the Telx colocation centers. This is nothing more than simple wired or fiber connections from a customer’s equipment rack, cabinet or cage to a passive interconnection panel in the interconnection space. The cross connect allows you to connect to any of the other services in the facility. If you change your mind or want connection to additional providers, it’s a simple matter of patching from your panel to theirs.

In addition to the passive cross connects, Telx also offers dynamic interconnections. They are a pioneer in Ethernet Exchange through a E-NNI or Ethernet Network to Network Interface. What this service does is allow Ethernet service providers to connect to each other through a standardized interface so that each provider extends the reach of their network. This is especially valuable for IP core networks which would otherwise have to first convert another protocol like SONET/SDH to achieve commonality with other networks.

In addition to 60 Hudson Street in New York City, Telx has another facility at 111 Eighth Avenue in NYC, two locations in New Jersey, two facilities in Chicago, two more in Dallas, plus colocation and interconnection centers in San Francisco, Atlanta, Miami, Phoenix, Charlotte, Los Angeles and Santa Clara. That’s 15 buildings spread out nationwide, with at least one close to your business location. They also have partnerships with Tata and Interxion for global locations.

If you have a need for high speed Internet access, cloud access, content delivery, low latency connections or other private line or network services, it is well worth your while to look into services and pricing for colocation and interconnection services from Telx and other premier service providers.
