10BASE-T | Cabletron Systems EMM-E6 Ethernet specification

A.8 EPIM-T (10BASE-T TWISTED PAIR PORT)

Internal Transceiver:

Cabletron Systems TPT

10BASE-T

Twisted Pair Transceiver

Type:

8 Pin RJ45 Jack (Figure A-1).

Figure A-1. EPIM-T (with RJ45 Port)

A slide switch on the EPIM-T determines the cross-over status of the cable pairs. The switch residing on the X side indicates the pairs internally cross over. If the switch resides on the = side, the pairs do not internally cross over. (See Figure A-2.)

Position X (crossed over)

1. RX+	5. NC
2. RX-	6. TX-
3. TX+	7. NC
4. NC	8. NC

Position = (not crossed over)

1. TX+	5.	NC
2. TX-	6.	RX-
3. RX+	7. NC
4. NC	8. NC
