BCM 450 v. 6 .

There is an existing T24 KIM unit attached to ext 266 that has been working fine for a long time. Customer wants to add another KIM to ext 282, which I did. The programming in the BCM says there is no KIM assigned to ext 266. The keys all have eternal dial numbers on them. I tried copying from ext 266 to 282 and got nothing.

If I assign a KIM to 266 (which already has keys programmed), will I loose what's on the KIM? Or should I assign KIM 1 to ext 282? Or just take the time and F*1 and put in each external dial number?

Thank you.
