EPIM SPECIFICATIONS
The TPRMIM-20/22/33/36 and CXRMIM provide a port for Cabletron Systems’
EPIMs. EPIMs let you connect to the main network using different media types.
Cabletron Systems offers a variety of EPIMs. The following sections explain
specifications for each EPIM.
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 cross-over positions.
