I just downloaded the Comdial DX-80 manual because I have never worked on that system before. In reviewing the manual the programming looks quite generic that I have seen on systems I
have programmed before.
If memory serves me correct you did it the easiest way. Otherwise, you would have to work with line groups with CO-1-CO-3 in Line Group 1 and CO-4 all by itself in Line Group 2.
All users would use Line Group 1 counting down CO-3, CO-2, CO-1, then if all line in Ling Group 1 are in use then Overflow to Line Group 2 (which only contains CO-4).
Of course if they ever added CO5 you would add it to Line Group 1...and you can see how Line Appearance could mess with someones head..." Why did they do it that way?"
Without saying, I am assume that CO-4 rings only on the Fax S/L extension, but it can be used by other if CO's 1-3 are in use?
