Overview
Introduction
Metrobility “twister” media converters represent the hottest technology
available for extending Ethernet networks. Since Metrobility first developed
“twister” media conversion, it has become a standard for providing cost-effective
means of integrating mixed media environments. As LANs grow and evolve, this
technology provides the ideal solution for building effective migration strategies.
Designed to meet IEEE 802.3 compliance, these media converters are compatible
with Ethernet devices from other leading network technology providers. This
increases the flexibility of your network by ensuring reliable data transmission in
multi-vendor as well as mixed media environments.
The information in this guide will help you to install and start using your “twister”
2111 media converter.
The Metrobility “twister” 2111 10 Mbps media converter provides seamless
integration of 10BASE-T Category 3, 4, and 5 twisted-pair segments with either
multimode 10BASE-FL fiber optic segments or thinnet coax in Ethernet environ-
ments.
To optimize your Ethernet network, the 2111 media converter provides seamless
operation in half- or full-duplex modes. Full signal restoration—with a low bit
delay—ensures accurate data transmission to and from LANs within an organization.
All signal activity is completely converted ensuring accurate communication and
collision detection in connected segments and allowing maximum media length to be
achieved on either side of the device.
The “twister” 2111 provides the following key features:
•
MDI-
II
/MDI-X switch on the twisted-pair port to eliminate the need for
crossover cables.
•
Transparency Mode that allows auto-negotiation by end points through the
media converter. (2111-13-B and 2111-15-B only.)
•
Auto polarity on the twisted-pair port.
•
Half- and full-duplex support.
•
Low bit delay to ensure accurate data flow across the network.
•
Transparency to data frame sizes.
•
Full compliance with applicable sections of IEEE 802.3.
