T1 over Ethernet – when does this become useful

Data transmission is one of the most critical aspects of any business operation. Even simple emails denote some kind of data being transferred. Internet connectivity therefore is usually an important aspect of any technology landscape for a business organization.


Most business organizations go in for T1 services because they offer:

  • Higher performance guarantees
  • Availability of network
  • Better network monitoring
  • Scalability and flexibility and
  • Cost effectiveness.


When does T1 over Ethernet come into play?

Normally, T1 services are delivered through fiber optic or copper lines. They are capable of carrying data at a speed of 1.54 megabits per second. Conventionally, twisted copper telephone lines are used to deliver even services. There is also the growing popularity of fiber optic lines. Most business organizations think of T1 over Ethernet when they are considering an evolution of their network. This can be due to increase in business operations or the need for more reliable and better reach as far as Internet access is concerned.


Why go in for T1 over Ethernet?

Even as a business organization thinks of progress into a converged network, it becomes important to take decisions such as upgrading of the T1 line, going in for a T3 line and whether it should be T1 over Ethernet.


Some of the things that T1 over Ethernet promise are:

  • Compliance with various Ethernet and Internet standards
  • Transparency in provisioning and maintenance
  • The ability of the service provider to deploy this technology without too many big changes to your premises and
  • Support for better voice quality and proprietary features as well.


A business organization may also be able to do away with the need to incur extra expenditure in terms of leasing T3 lines or going in for bonded T1 lines.


Choosing a service provider

While there are plenty of big names when it comes to choosing a service provider who can deploy T1 over Ethernet for you, it may be good to look out for important aspects such as the following:

  • Ability to seamlessly integrate T1 carriers into the Ethernet fabric
  • Native support for Ethernet services and other services such as POTS or plain old telephone service, fiber to the home or FTTH, ADSL and so on
  • The capability of delivering cost-effective solutions which leverage Ethernet to support various broadband services including voice over Internet protocol and IP video
  • Proactive network monitoring.


Most service providers also talk about making upgrades to your equipment. However, you should ensure that it does not mean a comprehensive refurbishing which will not only be time-consuming but an expensive proposition as well. It is good to clarify all the operations and expenses involved in deploying T1 services over Ethernet.



One of the most commonly used equipment when it comes to T1 services over Ethernet is the extender. Normally, this equipment uses TDM over IP technology or time division multiplexing over Internet protocol. It simply means that it enables TDM -based interface to transmit over the Internet using Ethernet-based networks.


Thus, going in for T1 over Ethernet should involve a bit of homework in terms of what the technology can deliver for better business and higher cost effectiveness.
