Gigabit Ethernet Replaces DS3 and T3
Author: John ScheblerT3 lines and DS3 bandwidth have always been an important part of telecom service offerings. The advent of carrier Ethernet WANs, point-to-point commercial microwave ovens, and DOCSIS 3 broadband cable networks have made these traditional communications services obsolete. Let's take a look at what's available for your business in the 50 to 1000 Mbps speed range.
Telco T1 line extensionBell Labs pioneered long-distance digital transmission shortly after World War II. Their first product was called T-Carrier and had compatible T1 and T3 services. T1 lines can replace 24 analog phone lines with T1 multiplex lines.
The T1 is designed to run over the same pair of copper wires that feed analog landlines for easy deployment. The T3 is an upgrade that runs on coaxial copper lines and 45Mbps microwave towers and can handle 672 voice lines. A protocol running on T3, called DS3, can also be transmitted over SONET fiber optic circuits. When the Internet arrived, T1 and DS3 were offered in clear channel versions to carry data packets. T1 operates at 1.5 Mbps and DS3 or T3 operates at 45 Mbps.
Over-fiber carriers take over Ethernet
Computer-generated data outpaces phone traffic these days. An almost ubiquitous standard is Ethernet over local area networks that run Internet Protocol or IP. With T1 or DS3, going from a computer key to a telephone key requires a protocol conversion at each end and vice versa. Carrier Ethernet puts everything on one standard, Ethernet.
Carrier Ethernet is implemented in two versions. The slowest version is Ethernet over Copper or EoC. It is a direct replacement for T1 lines and DS3 split services and operates from 1 Mbit/s to around 20 Mbit/s depending on circuit length. The main advantage is that it uses the same twisted pair cable as T1 lines or analog phone lines.
The fastest version of Carrier Ethernet is Ethernet over Fiber, or EOF. It is a technology that is rapidly taking over the world. EoF gives you end-to-end Ethernet at speeds of 10Mbps to 10Gbps and even 100Gbps in some cases. As expected, Ethernet over fiber easily replaces T3 line or DS3 bandwidth over SONET. It also offers the ability to easily upgrade to speeds in excess of 45Mbps at any time. With a Gigabit Ethernet port, you can start at 50 or 100 Mbps and scale up to 1,000 Mbps with a simple phone call or a mouse click on the Internet. No need to change equipment. Only the line speed and your monthly payment will change.
Another great feature of Carrier Ethernet, and some say the most important, is its lower cost than traditional communications services. You can get EoF with DS3 bandwidth speeds of 50Mbps for a fraction of what you'd pay for real DS3 over SONET. When switching from fiber to Ethernet, the cost of 100Mbps, 1000Mbps, and 10,000Mbps suddenly becomes affordable.
Wireless is fiber-free
Despite all the benefits of fiber, there are situations where it just doesn't work. First, for rural or remote areas where cables are not installed, probably not for phones Another is in dense urban areas where fiber has not yet been installed. Construction costs are huge either way, but that doesn't mean you're out of luck. Completely discard fiber or cable.
Point-to-point microwave ovens were the staple of long-distance telephones. Microwave transmission towers transmit phone calls every 30 miles. Microwaves can still be used on a small scale and at reasonable distances. In suburban commercial areas, a rooftop oriented toward a service provider antenna a few blocks away can give you gigabit-level bandwidth at a very low construction cost. It is also faster to install than running cables over the street.
In rural areas, your wireless Internet service provider or WISP offers a similar service, usually with slightly lower bandwidth levels, but similar to or better than DS3. Customers point their antennas at a service tower that may be miles away but in direct line of sight.
Another popular system is to use each cell tower to transmit Internet traffic to smartphones as well. 4G LTE is often available and can give you DS3 split performance at least as a download. Many small businesses can get the performance they need from 4G without the hassle of cables. It is especially useful for mobile or pop-up stores and individual owners Now that 5G is well implemented, cellular communications can easily replace DS3 and higher speeds.
One thing to keep in mind with wireless services, especially cellular, is that most plans have usage limits This is because the system can handle less fiber traffic and the bandwidth must be shared equally among users. However, if you can get a 300GB/month plan and pay much less than a DS3 or even a T1 line, going wireless can make a lot of sense.
Broadband can only simulate fiber
The old cable TV networks have been heavily modernized and now run mainly on fiber. It is the last link in your building that is powered by coaxial cable. With the transition from analog TV to digital TV, protocols have also improved. DOCSIS 3.0 and 3.1 offer high performance at a high price. You may be surprised to know that DOCSIS 3.0 supports download speeds of 1Gbps and 200Mbps The new DOCSIS 3.1 standard is good for 10Gbps downloads and 1-2Gbps downloads When DOCSIS 4.0 is implemented, this upstream capacity will increase to 6 Gbps.
Cable broadband is very popular among residential users and many businesses. The price can't be beat. The only limitation is that it is not available in many rural areas and the bandwidth is transmitted or shared between multiple users. So speeds may vary. As with wireless technology, there is a big difference between download speed and download speed. Downloads are typically a tenth of download speed or less. It reflects how internet traffic flows normally. In many cases, this may not make a difference to your operation, but if you need very high upload and download speeds and dedicated bandwidth, especially for cloud services, you may need fiber optic services from competing cable companies or other fiber network providers.
Do you still have older DS3 or T3 nodes, or do you need low-cost, high-performance bandwidth in the 50Mbps or higher bands? If so, learn about Gigabit Ethernet services available for your business
