Whenever it drops from 128K to 64K, i get all the stuff in the ISDN log and there is an "r" present indicateing that the channel is in a continous ringing condition. The only way to recover from this dilema is to either reset the unit or unplug the BRI. Leon McCalla -----Original Message----- >> I am frequently losing my connection with this unit.
