Hi guys,
I am trying to get lcr to work on a system, I am not a PBX technician. I do have all the programming manuals and have been able to set up program 16 and have assigned CO lines to groups. I have also through program 40 and 41 have access to the CO lines. I am having problem getting a line to light up when I dial a number. I press intercom then 9 and lcd reads "using lcr dial a number" . Then I dial number any I get a busy signal before any lines light up.
I have all local and long distance calls go to route plan 8 which i set up with the CO line groups. This is a old system programming book from 1993.

Thanks for any help
Mike
