E1

Similar to the North American T-1, E1 is the European format for digital transmission.

E1 carries signals at 2 Mbps (32 channels at 64Kbps), versus the T1, which carries signals at 1.544 Mbps (24 channels at 64Kbps). E1 and T1 lines may be interconnected for international use.

What do you want to know? What are you trying to do?

An E1 connection is a circuit that will run at 56Kbps or 64Kbps depending on how it's configured.

The circuit is not cheap, the equipment is relatively expensive. But it's a dedicated line.
