The selected entry on this page:

for the RJ45S shows something rather simple, a typical connector and a programming resistor. Obviously the value of the resistor would be selected at the time the whole arrangement is wired.

However shown here:
largely agrees with that one. And the matching one for the RJ41S which he has up shows a box marked PAD in the connector:

What I am asking about is one of, has anyone ever seen one, and would then know what is inside that box?
"This signature was present during the destruction of Troy, and knows where it happened."

For a more complete explanation of the uses of these RJ jacks (and  
others), take a look at this webpage:

RJ-45's were/are used extensively with dial-up modems, especially  
where RJ-11 operation would be unreliable. I have seen hundred's of  
them. RJ-41's less so.

a typical RJ45 would look like this:

with the resistor added at time of installation.

RJ41 would be similar but larger with the FLL/P switch.

BTW, the term "RJ45" existed in the telephony world long before  
Ethernet 10Base-T came along. The Ethernet LAN people usurped the term  
just because they happened to use the same physical 8pin hardware.
