When talking about Ethernet over copper vs T1, there are a few things that would be of interest to any business organization. Here are some of the most important ones.

Also abbreviated as EoC, Ethernet over Copper offers dedicated Internet access. Basically, it is delivered by using multiple pairs of twisted copper, and this is why it is known as Ethernet over Copper. A T1 line has the ability to carry 24 digitized voice channels or data at a rate of 1.544 megabits per second. It is costlier than quite a few options of connectivity but carries with it plenty of advantages as well.

There are a few ways in which we can compare Ethernet over Copper and T1 lines.  

Service level agreement

This is an important aspect when it comes to networks and service providers of Ethernet over Copper and T1 lines can offer you the same service level agreement or SLA. This is especially true when one is talking about bonded T1 lines as well. One of the reasons why Ethernet over Copper can come with such a robust service level agreement is because it runs on redundant pairs of multiple copper wires. So in the event that one pair goes down, the circuit will still be up and running.  

Dedicated bandwidth

Ethernet over Copper and T1 lines offer dedicated Internet access or DIA. This simply means that you will not be sharing your bandwidth with other customers when you invest in any of these technologies.  

Hardware

Ethernet over Copper vs T1 differs in this respect since Ethernet over Copper typically does not need any costly hardware. But if you have invested in a T1 line, you will also need to invest in hardware such as routers which may prove to be expensive. Furthermore, such a router will have to be placed on your premises. Ethernet over Copper uses some pretty inexpensive twisted copper pairs which can be found almost anywhere.  

Speeds

Both Ethernet over Copper and T1 lines offer symmetrical bandwidth speeds. This means that the customer can enjoy upload and download speeds which are equal and consistent. When it comes to upgrading to a higher speed, a T1 carrier may take a bit more time than a provider of Ethernet over copper. Typically, a T1 carrier will need to invest in new equipment and even new cabling, depending on your requirements.   However, if you want a higher speed with an Ethernet over Copper connection, all you really need to do is change your data plans. While a T1 line typically delivers data transmission at 1.544 megabits per second, Ethernet over Copper can be pretty flexible with carriers being able to provide anywhere from 3 megabits per second to 45 megabits per second.  

Costs

Depending again on the service provider that you have chosen, Ethernet over Copper can range around $200 for a 2 megabits per second connection. A T1 line can cost anywhere between $225 and $450 per month, depending on factors such as location, the service provider and so on.
