2.3.1 Ethernet Port Interface Modules

For an additional connection to the Ethernet network, the TPRMIM-20/
22, TPRMIM-33/36, and CXRMIM utilize the Cabletron Systems
Ethernet Port Interface Modules (EPIMs), Figure 2-2, that allow you to
connect the unit directly to:

•

Thin-net cable from the Coaxial Interface Module (EPIM-C).

•

Unshielded twisted pair cable from the 10BASE-T Twisted Pair
Interface Module (EPIM-T).

•

AUI cable, to an external transceiver, from the AUI Interface Module
(EPIM-A).

•

AUI cable directly from the Transceiver Interface Module with dual
internal transceivers (EPIM-X).

•

Multi-Mode Fiber Optic Cable, with SMA or ST connectors, from the
Fiber Optic Interface Modules (EPIM-F1/ EPIM-F2).

•

Single Mode Fiber Optic Cable, with ST connectors, from the single
mode Fiber Optic Interface Module (EPIM-F3).
