To connect your E1 to your PBX, use a straight through cable, i.e. pin 1 to pin 1, pin 2 to pin 2, etc.

Your telephone company should have already set the line mode, its either going to be B8ZS or AMI, most modern E1 circuit cards have an led on them that will tell you what mode the line is in, you will also need to set the frame type in the PBX to match the line, or, if the PBX will not use the line as it is, contact the phone company and they will change it for you. This may take them a few days.

Let me know what model Ericsson PBX you have, will make it easier to give specific advice.
