I have two 2811 Router with one NM-CEM-4T1 Module at each. Now I want to connect those with a E1 line to transport voice and maybe data (if it is possible).

Is this possible? If yes, what settings i have to do and what characteristics i have to look for?

Hello Otto,

these kinds of ports are specialized modules to carry one T1 over an IP backbone I would not connect them back to back they are thought to connect to TDM equipment.

Also they are probably more expensive then standard WAN modules.

if you want to carry a T1 over an IP backbone they are the right tool see the following link

Hope to help
