To have the backup PRI channel on our Adtran 550 we installed the second PRI Module. Now I have a hard time to programm it as the first one is programmed. To make sure that all the programming is done, I tried to use this module for the existing PRI - it doesn't work, so something is wrong. Is it any chance to copy settings from one mudule to another or I have to do it manualy? What exactly need to be copied? Also having issues with DSO's, getting conflict message.
