Black Box Explains
RJ-48.
Here’s how RJ-48C pinning compares
to RJ-48S pinning:
Pin RJ-48C RJ-48S
An RJ-48 plug is often mistaken for RJ-45. On the outside, the two look identical —
 2ECEIVERING 2ECEIVEDATA
both are housed in miniature 8-position jacks. The difference is in the wire pairing.
2 Receive tip Receive data -
In RJ-48, two of the wires are for transmit, two are for receive, and two are for the drain.
3 No connection No connection
The last two wires are reserved for future use.
4 Transmit ring No connection
There are three subsets within RJ-48: RJ-48C, RJ-48X, and RJ-48S. RJ-48C and RJ-48X are

very similar, though RJ-48C is more common. Both use lines 1, 2, 4, and 5, and connect T1 lines.
6 No connection No connection
RJ-48X connectors, however, have shorting bars. RJ-48S uses lines 1, 2, 7, and 8, and generally
