[TrunkCom] Control Frequency Only Mode

It works because the control data on EDACS or LTR sends the users to an
LCN # which is also where the scanner will be directed.

Remember lets say you know the LCNs of your system.  On the 250D for
example: the freq for LCN 3 must be programed into channel 3 like 003 or
103 or 203, LCN 5 must be programmed into 005 or 105 or 205 whatever
bank you are using.

This does work and I did not figure it out it was given to me by someone
years ago

Hi Rich, how did you figure this out/  I don't see how this can work.
