E3 to T3 connection

Is it tecnically possible to connect a router with T3 port to a router with E3 port?

Can you give me a detailed explanation of why yes or no?

Thanks a lot!

Re: E3 to T3 connection

Can you be more specifics on the ports on the router. A lot of the cards are T3/E3 card.


I would say No, you can connect a T3 port to a E3 port. The reason is different standards

The E3 standard is specified by ETSI (European Telecommunications Standards Institute). The bearer supports 16 E1 channels giving a capacity of 34.368Mbps

At 44.736Mbps (megabits per second), a T3 line transfers data almost 30 times faster than T1. The expanding need for bandwidth beyond T1’s capabilities was the impetus for T3’s development. With interest in the global network blossoming, Merit, IBM, and MCI formed a consortium called ANS (Advanced Network & Services). This group researched ways to increase the speeds at which data could travel and soon came up with the working concept of the T3 data transmission standard. The NSF (National Science Foundation), which established the NSFNet system of T1 backbones, quickly adopted the T3 standard and another step in the evolution of the Internet was underway.

Through multiplexing, a T3 line consists of 672 separate channels, each capable of transferring voice or data at 64Kbps(kilobits per second). The separate channels are allocated as needed to different requests for bandwidth or combined into larger pipelines for heavy loads. T3 lines are widely used in the infrastructure of the Internet, often providing the connection from ISPs (Internet service providers) to faster lines called backbones. Many universities and other large organizations utilize T3 to connect their facilities to the Internet, as well.
