Chapter 1 Introduction
Fast Ethernet Technology
The growing importance of LANs and the increasing complexity
of desktop computing applications are fueling the needs for high
performance networks. A number of high-speed LAN
technologies are available to provide greater bandwidth and
improve client/server response times. Among them, Fast
Ethernet, also known as 100Base-T, provides the smoothest
migration path for the current 10Base-T technology. The non-
disruptive and smooth evolutionary nature of Fast Ethernet, plus
its prevailing market acceptance, guarantees it as the most cost
effective and high-performance networking solution of the future.
100Base-T networks essentially look and act like 10Base-T
networks, only faster (see Table 1-1, page 8). 100Base-T
provides 10 times the performance of 10Base-T while retaining
most of the same cabling rules and the CSMA/CD media-access
method. 100Base-T also uses the same packet format, packet
length, error control and management information as 10Base-T.
As such, 100Base-T is recognized as the true and rightful heir of
10Base-T.
For flexibility, the 100Base-T specification contains three
different cabling schemes, 100Base-TX (Cat 5 UTP), 100Base-T4
(Cat 3,4 or 5 UTP) and 100Base-FX (fiber optic). 100Base-TX is
probably the most popular choice since it enables users to retain
their existing 10Base-T cabling infrastructure and easily migrate
to Fast Ethernet.

Table Chapter 1 -1, Ethernet vs. Fast Ethernet
Switching Technology
Another approach to pushing beyond the limits of Ethernet is the
development of Switching technology. A switch works in the
MAC address level, bridging multiple Ethernet segments to
prevent unnecessary network traffic from passing one another. In
a properly subdivided switched LAN, the net result is a full and
transparent bandwidth for each segment.
Switched Ethernet vs. Legacy Ethernet is analogous to using
private telephone lines vs. party lines. By connecting to a
switched port, each Ethernet segment has dynamic full
9
performance or “wire-speed.” Therefore, a switch effectively
splits a physical shared-access LAN into bridged multiple LAN
segments. Each segment supports a workgroup and even
provides a dedicated connection to a desktop server. The
outcome is a multiplication of the overall available bandwidth and
a more predictable performance under heavy network loads.
10/100 Switching Technology
Just as 100Base-T is an extension of the existing 10Base-T
technology, 10/100 Switching is merely an extension of
10Base-T Switching. The 10/100 Switch provides not only the
10/100Mbps high-speed transmission rate per segment, but it also
bridges 10Base-T and 100Base-T into a harmonious network.
Combining Fast Ethernet and Switching technologies, the 10/100
Switch provides enough bandwidth to satisfy the most demanding
workgroups, as well as a high-speed backbone link.
Benefits of Switching
From the technical point of view, Ethernet switching technology
dramatically boosts the total bandwidth of a network. It also puts
configuration flexibility and bandwidth adaptability into the local
workgroups where the majority of work is generated from a
business operation. Switching further eliminates the congestion
problem inherent to the contention oriented Ethernet CSMA/CD
protocol, thereby improving predictable response times under
heavy network loads. In the past, this congestion under heavy
loads was alleviated using an expensive routing technology.
From the applications point of view, the new wave of object
oriented distributed Client/Server applications demands higher
bandwidth and tighter integration of client workstations with
servers. The legacy shared-access 10Mbps Ethernet technology
10
can no longer provide both bandwidth and predictable response
times to this new generation of workgroup computing.
From an economical point of view, Fast Ethernet switching not
only satisfies both technical and business requirements, but also
preserves the users’ existing investment in the huge 10Base-T
Ethernet installed base. This compatibility insures a path for
users to add, change, and migrate to Fast Ethernet capabilities as
needs arise. It also provides a low cost and flexible bandwidth
solution directly to local workgroups, where the majority of work
is generated and reducing the need of expensive routers that
usually cater to the network backbone.
Introducing the TE100-S55
The word “flexible” best describes the characteristics of the
TE100-S55 . Not only does it provide five fixed 10/100Mb ports,
but it also provides an open slot for adding an 8-port 10Base-T
module, a 100Base-FX/TX port or an ISDN router module.
Users can hand-select the necessary modules to fit their individual
needs.
With expandable switch functionality and ISDN router support,
the TE100-S55 brings to the workgroup capabilities normally
found in more expensive, chassis-based products. Dual-speed
10/100 configuration options also make the product ideal for
integrating Fast Ethernet technology into existing 10Mbps
network.
Both fixed and modular network ports on the TE100-S55 feature
NWAY Auto-negotiation, to simplify installation and use.
NWAY Auto-negotiation senses the network speed when cabling
is inserted into the port, and automatically transmits at either
100Mbps or 10Mbps. In addition, it detects whether the device
transmitting to the port is utilizing half or full-duplex signaling
and configures itself without user intervention. When taking
advantage of full duplex signaling, the TE100-S55 literally
