Module Function Description
10BaseT
Repeater
RR-EPR-4T/FL Independent four 10BaseT and one/two
10BaseFL ports repeater for RADring
hubs. Can be used with a RADring hub
without an Ethernet bus
The EPR-4T/FL repeater module connects Ethernet
LANs to the RADringII hub. It supports up to 4 UTP
or screend UTP ports and one/two fiber-optic ports.
10BaseT
Repeater
RR-EP-4FL Four 10BaseFL ports repeater for RADring
hubs with Ethernet bus. Can be
connected to the hub’s bus as part of an
Ethernet segment
The EP-4FL repeater module connects Ethernet LANs
to the RADringII hub. It supports up to 4 fiber-optic
ports.
RR-TRE-8D Token Ring Elementary bridge, enabling
connection of two remote LANs, each
consisting of up to 80 stations
Connects two remote Token Ring LANs over an
async/sync WAN link (4.8 - 512 Kbps) - operates
opposite RR-TREs or discrete TRE-8 units
Ethernet
Extension
Module
RR-EP-1T/2W Three ports repeater with one 10BaseT
port and two WAN ports for connecting a
remote station via a standard WAN
connection. Used in RADring hubs with
Ethernet bus. Can be connected to the
hub’s bus as part of an Ethernet segment
The EP-1T/2W repeater module connects Ethernet
LANs to the RADringII hub. It supports one UTP or
screend UTP port and one cudtomized Y cable
terminated with a 50 pins SCSI connector.
Note
EP modules are used in Radring II systems, while EPR modules are used in
Radring I systems.

Module Function Description
System RR-CML/NM Common Logic with Network
Management is the out-of-band agent of
the complete RADring hub
The CML/MN provides physical control and
monitoring of the hub, as well as out-of-band
connection to the management station
RR-CML/IB In-band Management Agent is the in-band
agent for the respective ring it is placed in
Acts as an SNMP agent and provides advanced
features such as security functions and automatic
recovery from beaconing. It communicates with the
management station over the Token Ring network
System RR-CML/IB-E In band Managment Ethernet agent is the
inband agent for all the Ethernet modules
in the hub
Acts as an SNMP agent and provides advanced
features, such as security functiuons, traffic counters
and port indications/controls.
Communicates with the Managment station over the
Ethernet network.
