What’s the Difference Between T1 and E10 Internet?

Reading Time: (Word Count: )

The most efficient design of your telecom system depends on many factors. The type of use -calls, video, data transmission – is important, along with number of users, locations, long distance, and even the time of day when your traffic spikes. It’s a great idea to get a telecom audit to determine which type of setup will provide the right amount of service with the highest level of efficiency and no wasted money.

What is T1?

T1 is a digital carrier line with a data transmission (upload and download) rate of up to three megabits per second (Mbps). A T1 line contains 24 digital channels and requires a digital connection called a Customer Switching Unit (CSU) or Digital Switching Unit (DSU). T1 lines are an affordable way to provide reliable, high-speed connectivity to 200 or more users for voice and data, depending on usage.

T1 lines are an economical choice to connect businesses with outside hosting for websites and apps. Users will have secure data and voice connectivity and nearly 100% uptime.

As the business grows, adding lines to accommodate additional users is easy and seamless for both customers and employees.

Wht about E10?

The data transmission rate of E10 is a faster option at up to 10 Mpbs, and can handle additional traffic. One E10 line carries 32 channels at the speed of 64 Kbps, with two of the channels dedicated to signaling and controlling. The most significant differences between T1 and E10 lines are speed and the number of available channels. With more channels, E10 can handle considerably more traffic than T1 lines.

E10 offers a full duplex ethernet port to deliver symmetrical speeds for uploads and downloads…at the same time. It offers superior reliability with lower latency, jitter, and packet loss compared to other telecom solutions.

An enterprise-level solution for medium to large businesses with a lot of users online, E10 lines address multiple locations and heavy data, video, and voice usage. It offers the reliability and scalability to host high-traffic websites or applications in a high-speed, secure virtual environment.

With E10 lines in place, you have complete control of your budget. If your data transfer demands are high and consistent, a fixed rate might be the right option. For use that fluctuates with the day of the week or the time of day, you might cut costs with a usage-based rate.


Businesses change. They grow, expand, and sometimes shrink due to demand and market forces. When your business changes, either a T1 or E10 solution can be scaled up or down to meet your specific needs. Which means you can pay for exactly what you need and no more, even if your needs change.
