I used to do phone support for a phone company / isp and I have no idea what you just wrote.

To be fair, 5 out of the 6 phone support agents I talked to at Optimum (an ISP) did not know what IPv6 is, so saying you used to do phone support for an ISP isn't really saying much.

RJ45 is a connector with a key notch sticking out and a "programming" resistor joining two of the pins. It won't work for Ethernet at all, the plug side can't even fit in the 8P8C socket Ethernet uses. If you grind off the key it'll still not work, because of the embedded resistor. Also the pinout is totally wrong, so even if you didn't have the resistor it wouldn't work. None of the RJ connectors have the correct pinout for Ethernet.

He said RJ45 is an AT&T part/reference number. Just like RJ11 which is your small phone plug that had 6pins, more rare.

		Nit: RJ11 has two contacts. RJ11, RJ14 and RJ25 all used the same 6P housing though, making them 6P2C, 6P4C and 6P6C connectors, respectively. Things sold as RJ11 is often 6P4C, making for another error. The rule of thumb is that anything referred to as RJ-something is likely wrong.
