I'm trying this from memory but I think station 10 will be the first 2 pair on J1. The blue pair will be voice and the orange pair will be data.
The next 2 pair will be for the console of station 10 if you use one.
Next station (port 11)will be next 2 pair. The 2 pair that follow that will be the console for station 11. The rest of the ports do not have console ports. One point with this system, if you are talking on one station and unplug the data paired station your call will be dropped. Paired stations are 10&11, 12&13 and so on.
I'm not in the office to look this up but Ed or one of the Comdial mods will have the book for sure. They will set you straight if I messed up. laugh
