Ethernet Better Than a T3 Line
Author: John SheplerSoon T3 voice and data lines became the mainstay of medium and large businesses. Today, the once impressive 45 Mbps doesn't seem so fast anymore. Our business applications require more like 100 Mbps or 1000 Mbps Medical universities, design firms and video production studios are increasingly interested in 10 Gbps speeds and are planning to go even further. If you still have a T3 line contract, you may find that you can now get more bandwidth for the same price or less.
What is the T3 line?The name T3 is part of the T-Carrier system developed by Bell Labs during the post-war technology boom. It was originally designed to handle large volumes of phone calls and still serves that role for some large enterprises and call centers. Before T-Carrier, telecommunications were based on analog technology. The T1 and T3 digitized it and led us to the Internet that we are on today.
The T3 672 has a speed of 45 Mbps, which is enough for making digital phone calls. This makes it more efficient than making 672 separate twisted pairs of copper wire like telephone lines. T3 was once transmitted over large coaxial cables or microwave transmission stations. It has recently been added to SONET fiber optic cable and is called DS3. DS3 is a data format that runs on a physical T3 line, so DS3 and T3 mean the same thing.
The channel version of T3 is used to handle these 672 phone calls, each on a different channel or time slot of the data stream. For data transmission, unreleased versions of T3 can handle data at speeds up to 45 Mbit/s, including popular packet-switched networks.
Ethernet replaces T3.
Currently, all communication is carried out over digital networks, and the most popular protocol comes from Ethernet. Even phones have switched to Ethernet interfaces, so instead of using separate cables, they connect to the same network as computers. This is called VoIP or Voice over Internet Protocol. When the computer and phone are on the same network, it is useful to transfer all data over the LAN and WAN using Ethernet.
That was it. Carrier Ethernet, the long-haul version, replaces other telecommunications protocols such as T-Carrier for copper lines and SONET for fiber optic systems. Full Fiber Ethernet is currently in place. It is often called a WAN for Ethernet Wide Area Network.
Cost and performance advantages of Ethernet
The first advantage of Ethernet transmission over long distances is that it is directly compatible with most corporate networks. Plug the carrier ethernet cable into your router. No separate block or protocol switching module is required to support T1 and T3 lines.
A second advantage is that Ethernet is easy to extend. You can run at any speed from the driver up to the physical port limit. T-Carrier and SONET protocols are designed for specific speeds and upgrades require hardware changes. Your line capacity is determined by your service provider as per your contract. You can easily add or subtract as your needs change and it will be reflected in your invoice.
The biggest incentive to switch to Ethernet WAN service is cost You may be surprised at how much you can save by switching from your old telecom service to Ethernet broadband. Ethernet is almost always cheaper per Mbps. Sometimes the difference can be two or more.
Most of the savings will come from a competitive environment with a single provider of fiber-optic Ethernet and legacy telecommunications services. There are many companies that can provide Ethernet bandwidth for your business at competitive prices.
Fiber is more affordable than ever. Upgrading cell towers to 4G LTE and 5G requires rapid expansion of fiber networks Copper is yesterday's news and periodically rusts to the ground. This is the future of fiber and wireless networks.
Have an old T3 or DS3 service and think you can get a better deal? It's clear. Check the price and availability of Ethernet WAN service for your corporate address You can get bandwidth for the same price or less than what you are paying now.
