I want to find any info on keyphone protocols, such as panasonic,
nitsuko, etc

We design small hi tech, analog PABX and want to make compatible with
others keyphones

Thanks in advance!

Generally they are proprietary. You would probably have to approach the
manufacturer concerned.

>Good luck every manufacturer is different, not only in the data format but in how the data, power, and audio is delivered to and from the set.This is why a Lucent phone wont work on a Comdial system, a Comdial wont work on a Toshiba and a Toshiba wont work on a Nitsuko, ad nauseum. My suggestion would bet to select a phone and design your switch to be compatable with it.
