Is it possible to add caller-id to a DK16 system?

A DK-16e, yes, but a DK16, no.

I will have to check more specifically which one I have. How would caller-id be added to a DK-16e?

Hey Ringtone I think all you need is the caller Id card I use to install the DK 40 And 424 I know on the 40 you can have caller id.

Its called a TCIU if I remember correctly and it should attach to the TCOU.

I know that's the one for the 40, but I'm not sure it will fit in the 16e. That system came out quite a while ago, and the memories fade..... :shrug:

I went through my manuals for the 16 and found no reference anywhere to caller ID or the CID daughterboard. Unfortunately, I do not have a 16e manual, but as the 40 used a TCIU2 for CID, I suspect that there was a TCIU (1) for the 16e.
