EPIM SPECIFICATIONS

B.1 EPIM SPECIFICATIONS

EPIMs enable the connection of the NBR to different media types. Cabletron Systems offers a variety of EPIMs. The following sections explain speciﬁcations for each EPIM.

B.2 EPIM-T

The EPIM-T is an RJ45 connector supporting UTP cabling. It has an internal Cabletron Systems TPT-T 10BASE-T Twisted Pair Transceiver.

The slide switch on the EPIM-T determines the cross-over status of the cable pairs. If the switch is on the X side, the pairs are internally crossed over. If the switch is on the = side, the pairs are not internally crossed over. Figure B-1 shows the pinouts for the EPIM-T in both positions.

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
