Just to explain more completely (perhaps) what's happening with EDACS controllers:
If I have an EDACS system being tracked, and the control channel is lost, Unitrunker ERASES all LCN/Frequency information from the system/site, and then detects the system as a 'new' one, when it again hears a control channel.
IF I manually enter the LCN/Frequency information into the old (correct) system/site, and then restart monitoring, it will open a new system, but if I then enter the frequency into the control channel it's detected, it will realize it's the 'old' system, and switch to that, de-creating the 'new' limbo system.
Just getting it to NOT delete the LCN/Frequency info for a site, when it loses the control channel, would help.
Does this whether or not site lock is selected.
