Yes, I understand the alarm configuration. But the network hub with the RJ-31X port is the problem area. It is my understanding that when I unplug the RJ-45 connector that goes to alarm panel, from that port, that the hub should return to normal state. That is not the case. Am I doing something wrong or do I have a bad master hub?

Also, what is the proper configuration of the RJ-45 that plugs into the RJ-31X port? 568A?? And, which pair would then land on T1 - R1?
