Introduction
1.1 General Description
The RADring is a Token Ring and Ethernet connectivity center supporting
IEEE802.5 networks at 4 and 16 Mbps and IEEE 802.3 networks at 10 Mbps.
The system provides a highly compact, modular approach to the
implementation of Token Ring and Ehternet LANs. Various media types
including shielded twisted pair (STP), unshielded twisted pair (UTP),
Screened UTP, fiber optic cable and coaxial cable are supported.
The RADring is ideally suited for all sizes of Token Ring installations. It also
provides an easy way to migrate the Token Ring LAN, or parts of it, to
Ethernet. The network size can be increased in small increments, by adding
modules as required, to support the correct number of connections. Its
flexible design, modularity and multimedia capability result in a system easily
adapted to changing user requirements. Data integrity is ensured at the
module, segment and lobe level through automatic recovery, beacon
detection and automatic bypassing. The redundant power supply feature
provides additional reliability.
RADring also provides direct connectivity to local and remote Token Ring
LANs by means of integrated Elementary Bridge modules.
When RADring is configured with the network management option, the
RADview Network Management System provides continuous centralized
monitoring and control, with immediate identification and isolation of
network failures.
