REPEATER MEDIA INTERFACE MODULES

Repeater Media Interface Modules (RMIMs) also called RICMIMs for
Repeater Interface Control MIMs, shown in Figure 2-1, are based on
Repeater Interface Technology that enables each of the modules to function
as an independent 802.3 compliant multi-port repeater. The EMME
communicates with the repeater MIMs over Ethernet channels B and C of
the FNB. The following repeater MIMs are currently available:
• CXRMIM
- The coaxial version of the repeater MIM is equipped with twelve
10BASE-2 coaxial connectors. The module also includes an EPIM
port.
• FORMIM-22
- The FORMIM-22 includes twelve FOIRL/10BASE-F ports with
ST type connectors.
• TPRMIM-20/-22
- These MIMs are equipped with RJ45 connectors and one user
configurable Ethernet Port Interface Module (EPIM) which
provides a single port interface for an AUI, fiber optic, twisted
pair, or coaxial connection. The TPRMIM-20 has nine RJ45
connectors and the TPRMIM-22 has twenty-one RJ45 connectors.
• TPRMIM-33/-36
- These MIMs come equipped with 50-pin champ connectors, (the
TPRMIM-33 with one and the TPRMIM-36 with two). Each
connector provides the MIM with 10BASE-T twisted pair ports
(twelve for each champ connector). These MIMs also have a user
configurable Ethernet Port Interface Module (EPIM) providing a
single port interface. The TPRMIM-36 also has an AUI port.
• TPXMIM-20/-22
- These MIMs are equipped with RJ-45 connectors and one user
configurable EPIM. The TPXMIM-20 has nine RJ-45 ports while
the TPXMIM-22 has 21.
