Is this an Ethernet cable running to my alarm panel?
So I think it actually IS an Ethernet cable.
Looking farther into the hole on the cable markings, I see &quot;ETL VERIFIED TO TIA/EIA 568B.&quot;
However, I think I don't know where the cable comes out on the other side. The ones in the &quot;structural panel&quot; that are yellow are all rated CM and this one is CMR, so I don't think it is the same cable.
