100BASE-TX Technology Overview

100M bps Fast Ethernet is a relatively new standard specified by the IEEE 802.3 LAN committee. It is an
extension of the 10Mbps Ethernet standard with the ability to transmit and receive data at 100Mbps, while
maintaining the CSMA/CD Ethernet protocol. Since 100Mbps Fast Ethernet is compatible with all 10Mbps
Ethernet environments, it provides a straight-forward upgrade without wasting your investment in
hardware, software, and personnel training.

The MR9600-100 provides an easy, affordable, high-performance, seamless, and standards-based
migration path to a 100BASE-TX LAN while preserving your initial investment and use of 10Mbps
Ethernet LANs.

The MR9600-100 complies with IEEE802.3u, 100BASE-TX, IEEE 802.3 and 10BASE-T standards. The
MR9600-100 has five 10Mbps twisted-pair ports and two 100Mbps twisted-pair ports. The MR9600-100
provides a store-and-forward token passing scheme. Filtering and forwarding rates for the MR9600-100
run at wire-speed, reducing latency within and across segments.

Cables and Connectors

The MR9600-100 supports Category 5 unshielded twisted-pair (UTP) cables. Cat 5 UTP cable uses the
same RJ-45 connector used with 10BASE-T, wired in the same configuration. Please note that the punch­down blocks in the wiring closet must also be Category 5 certified. Where these blocks do not meet the
standard, an upgrade is necessary.

Topology

A Fast Ethernet workgroup is configured in a star topology and is built around a maximum of two
repeaters. Each workgroup forms a separate LAN (also known as a “segment” or “collision domain”), and
these workgroups can be easily interconnected through switches, bridges, or routers to form one LAN
large enough to encompass a high-rise building or campus environment. Recent innovations in LAN hub

Network

Hubs

1 Introduction

technology such as stackable hubs, coupled with the decreasing cost of switches, bridges, and routers,
allow the design of low-cost, efficient Fast Ethernet workgroups and enterprise LANs.

The following factors strongly influence the architecture of Fast Ethernet networks:

• The EIA/TIA 568 Wiring Standard imposes a 100 meter limit on horizontal runs of twisted-pair cables;

that is, connections from the wiring closet to the end-station.

• Fast Ethernet’s increased operational speed reduces the maximum distance between all elements of the

LAN (see below).

• The EIA/TIA 568 Wiring Standard does not support the use of coaxial cables for horizontal wiring.

The network diameter, which is the distance between two end-stations in the same collision domain, is the
primary difference between traditional Ethernet and Fast Ethernet. Due to the increased speed in Fast
Ethernet and adherence to the EIA/TIA 568 wiring rules, the network diameter of a Fast Ethernet collision
domain is limited to 205 meters; in contrast, the maximum 10BASE-T Ethernet collision domain diameter
can be up to 2500 meters.

While 10BASE-T hubs are all functionally identical, Fast Ethernet hubs are divided into two distinct types:
Class I and Class II. A Class I hub repeats all incoming signals on one port to the other ports by first
translating them to digital signals and then retranslating them back to line signals. These translations are
necessary when connecting various network media to the same collision domain, such as when combining
two wire-pair 100BASE-TX media with four wire-pair 100BASE-T4 media. Only one Class I hub can exist
within the same collision domain, thus this type of hub cannot be cascaded. A Class II Hub (or
“repeater”), on the other hand, immediately repeats all incoming line signals on one port to the other
ports; no translations are performed. This type of hub connects identical media to the same collision
domain; for example, TX to TX. At most, two Class II hubs can exist within the same collision domain.
The cable used to cascade these hubs is called an inter-repeater link (IRL).

As mentioned earlier, stackable hubs can be used to increase the number of available nodes in a collision
domain. An entire hub stack counts as a single hub (repeater).

Connectivity Rules

• The maximum length of a twisted-pair segment (that is, distance between a port in the hub to a single-

address network device such as a PC, server, or LAN switch) is 100 meters.

• The maximum diameter in a collision domain is about 205 meters using two Class II hubs (or hub

stacks) and 200 meters using one Class I hub.

• Between any two end-stations in a collision domain, there may be up to three segments and two Class

II hubs or two segments and one Class I hub.

Switching Technology

Switching is fast becoming the industry standard for pushing the limits of existing Ethernet networks. A
switch bridges Ethernet packets between Ethernet and Fast Ethernet LAN segments at the MAC address
level of the Ethernet protocol.

CommPlete Communications Server 7

MR9600-100 User Guide

The difference between switched Ethernet (10Mbps, 100Mbps, or both) and traditional Ethernet is
analogous to the difference between a private phone line and a party line. With switched Ethernet, each
workgroup has a “private line” so that transmitted packets don’t have to wait as long to gain access to the
network. When connected to a switched port, each Ethernet segment has full “wire-speed” access, so a
switch effectively divides a single Ethernet LAN into bridged multiple LAN segments. Each segment can
support a workgroup or even provide a dedicated connection for a key workstation or server. The result of
dividing an Ethernet LAN into multiple segments is a multiplication of internal bandwidth available to all
stations on the LAN and a reduction in latency rates during peak-use periods.

Benefits of Switching

Ethernet switching technology drastically increases the total bandwidth of a LAN. It also provides
configuration flexibility to local workgroups which allows the network administrator to better control how
network resources are distributed against network load. Switching helps reduce the congestion problems
inherent in the contention-oriented CSMA/CD protocol, thereby improving network response during high
utilization periods.

Also, currently popular distributed client/server applications often require higher bandwidth and tighter
client-to-server integration. Legacy 10Mbps Ethernet often is unable to provide a sufficiently
sophisticated platform for users to be able to take full advantage of such client/server applications.

Fast Ethernet switching not only satisfies both technical and business needs, it also preserves the current
investment in the huge 10BASE-T Ethernet installed base. Compatibility with 10Mbps Ethernet ensures
that users will be able to migrate to Fast Ethernet at a pace appropriate to their installation and needs.

10/100 Switching Technology

An integral extension of Fast Ethernet, 10/100 switching provides not only a 100Mbps high-speed
connection for carrying aggregated 10Mbps traffic, it also handles the necessary conversion of the MAC
layer between 10BASE-T and 100BASE-TX. Combining Fast Ethernet and switching technologies provides
both bandwidth for local workgroups and a high-speed link to carry local traffic elsewhere in the network.

Introduction

This chapter describes how to install the MR9600-100 Controller into a CommPlete Communication Server
CC9600 chassis. This equipment should only be installed by properly qualified service personnel.

The MR9600-100 Controller assembly consists of the MR9600-100 Controller card, an integrated Ethernet
switch card, and a common front panel. Figure 3 shows the layout of the MR9600-100 card without the
switch. The MR9600-100 assembly plugs into bus connectors on the inside of the CC9600 chassis. Three
communications connectors on the switch module are accessible from the back of the CC9600 chassis: a
DB-9 serial connector for MR9600-100 diagnostics and configuration, and two 10/100M bps connectors for
network access.

Installation Procedure

1. Unpack the MR9600-100 assembly from its packaging, and save the packaging for possible future

use. Perform a visual inspection of the MR9600-100. If you are concerned about the condition of the
MR9600-100, call Technical Support for instructions.

2. Remove the blank controller panel or previous MR9600-100 controller from the CC9600 chassis. The

MR9600-100 is hot-swappable.

3. Holding the MR9600-100 by its handle and the edges of the bottom panel, place the MR9600-100

into the open controller slot of the CC9600. Make sure the edges of the MR9600-100 card mate
properly with the plastic guides in the CC9600.

4. Slide the MR9600-100 into the CC9600 chassis until you feel the MR9600-100’s connectors fit into

the bus connectors at the back of the CC9600.

that for 10M bps connection, you can use Category 3 (Cat 3) or Cat 5 cable; for 100M bps connection you
must use Category 5 (Cat 5) cable.

Serial Cabling

Use the 9-pin RS-232 connector on the back of the CC9600 chassis for diagnostics and configuration.

Network Connections

If any port on the MR9600-100 is set for full duplex operation, the device (or LAN) connected to that port
must also be set for full duplex operation. Refer to the following sections on 10M bps and 100M bps ports
for specific requirements.

10M bps Ports

The five 10M bps ports are used internally for the four CommPlete segments and the Controller. The 10M
bps ports operate at a user-selectable effective speed of 10M bps in half-duplex mode, or at 20M bps in
full-duplex mode. In either mode, the twisted-pair connector can operate over 100 meters of Category 3, 4,
or 5 UTP/STP cable. Note that the MR9600-100 back panel has two RJ-45 connectors. Refer to Figure 2 for
the proper connector type (cross-over or straight through).

2 Hardware Installation

100M bps Ports

The two 100M bps ports use standard RJ45 twisted-pair connectors with unshielded or shielded twisted­pair (UTP/STP) wiring. The 100M bps ports operate at an auto-negotiable neffective speed of 100M bps
(in half-duplex mode) or 200M bps (in full-duplex mode). In either mode, the twisted-pair connector can
operate over 100 meters of Category 5 UTP/STP cable. (Cat 3 cable can be used if the 100M bps port is
running at 10M bps.)

The two 100M bps ports can auto-negotiate for 10/20/100/200M bps operation. Note that the MR9600-100
back panel has two RJ-45 connectors. Refer to Figure 2 for the proper connector type (cross-over or
straight through).

Cable Types

Under most conditions, the ports on the MR9600-100 may use normal straight-through cables. Some
circumstances, however, may require cross-over cables (i.e., cables in which the twisted-pair outputs have
been crossed). See Appendix B for more information on cable pinouts.

MR9600-100 User Guide

Setting the Duplex Mode (JP1-JP5)

Each 10M bps port can be set for half-duplex or full-duplex operation. At half-duplex operation, packet
transmission and reception do not occur simultaneously, thus communication speed is limited to 10Mbps
in 10BASE-T mode. At full-duplex operation, packet transmission and reception occur simultaneously,
thus communication speed is doubled to 20Mbps using 10BASE-T mode. Full-duplex operation can be
used on links between the MR9600-100 and any device (or station) that supports full-duplex operation.

Set the 10M bps duplex mode using jumpers JP1-JP5 on the top PCB located behind the front panel.
To set a port (e.g., “P1” in the figure below) to full-duplex operation, jumper the top two pins together for
that port.
To set a port (e.g., “P5” in the figure below) for half-duplex operation, jumper the bottom two pins
together for that port.

Refer to the figures below for 10M bps Half-duplex/Full-duplex mode jumper locations and settings. Note
that it is not necessary to turn off power to the MR9600-100 when changing the duplex mode setting.

Introduction

You can operate the MR9600-100 by using the front panel indicators for information (see Chapter 6). But if
you install the optional MultiModemManager software, you can operate the MR9600-100 by running
windows-based menu and command functions from a dedicated management console (refer to the
MultiModemManager User Guide).

Security

The MR9600-100 has a security system to prevent unauthorized system modification by Telnet, Web
browser, or FTP users who access the system via the TCP/IP network or the diagnostic serial port on the
back of the CC9600 chassis. SNMP and MultiModemManager software security is accomplished by
selecting SNMP read and write community strings. Note: SNMP issues relate to the SNMP-managed
MR9600-100 chassis, but not to the unmanaged CC9600HB-100 Ethernet switch.

There are three levels of security:
passwords for each level (see following table).

Once you are logged in, you can change your user ID and password by using the commands userid to
change your user ID, and passwd to change your password (see Chapter 5).

File System

The MR9600-100 stores configuration, security, and event information in files. There are two drives on the
system: A and B. The A drive is used for nonvolatile information such as configuration and security
database files, and is about 1 MB in size. The B drive is for volatile information such as event files, and is
about 6.5 MB in size. Each drive has an MMM directory on it. A:\MMM stores all configuration
information for the system. B:\MMM\MR.LOG contains all of the event files for the system. The file system
can be accessed either through the command line interface or by using FTP.

Event Files

One event file is created for each hour in the format MMDDHHYY.HR, where MM is the month, DD is the
day, HH is the hour, and YY is the last two digits of the year. When the drive fills up, the oldest .HR file is
deleted. The number of events your MR9600-100 will hold depends on the number of calls you receive in a
day. Event files can be FTPed from the MR9600-100 and analyzed using the Statistical Analyzer, which is
part of the MultiModemManager software.

SNMP Interface

The MR9600-100 can be monitored and controlled by using SNMP through the MultiModemManager or a
third party SNMP manager.

Note that SNMP issues relate to the SNMP-managed MR9600-100 controller, but not to the unmanaged
CC9600HB-100 Ethernet switch.

To receive traps from the MR9600-100, the SNMP manager should log in using the entry in the system
table. In that entry, do a set of “login PUBLIC.” When you are done monitoring the MR9600-100, do a set
of the same variable with “logout.” This will stop traps being sent to your station. MultiModemManager
does this automatically.

Command Line Interface

The MR9600-100 provides a complete command line interface that enables you to do most of your
management functions through either the MR9600-100’s diagnostic serial connector or, more likely, by
using Telnet. When first setting up your MR9600-100, you must use the MR9600-100 diagnostic serial
connector to set up the system’s TCP/IP information, such as its IP address, default gateway IP address,
etc., as described in the MR9600-100 Quick Start in Chapter 3.

3 Operation

When you first connect with the MR9600-100, either in Telnet or by using the serial port, you will be
prompted for a user ID and password. Enter the correct user ID and password for the desired security level
(see “Security” on page 18). Once you are logged in, the screen should show the following information.

The command line prompt is the current directory followed by a
MR9600-100’s two drives, A and B, by using the cd command or by typing A: or B:. A standard set of DOS
and UNIX file system commands are available, though in limited fashion (no wildcards are supported,
etc.). See Chapter 5 for command functions and limitations.

Some commands allow you to monitor activity on the CommPlete’s modems. The commands
getmodems, getcalls, and getfaults allow you to see the current state of the modems, the connection
history of the modems, and the history of faults on the modems, respectively.

Information that does not fit on the screen is displayed one page at a time by using a --MORE--
prompt. When you see this prompt, you have the option of quitting the list by typing Q or continuing the
list by typing anything else.

Some commands allow you to change the current state of the modems. With the commands oosset,
oosclear, reset, and config, you can set modems in or out of service; reset them, or configure them,
respectively.

MR9600-100 User Guide

Telnet Interface

Telnet is a standard Internet protocol that allows a remote connection between two systems connected to a
TCP/IP network such as the Internet. The MR9600-100 can be managed remotely by using Telnet. Telnet
can give the user access to all management functions through the command line interface.

There is an inactivity timer associated with the Telnet session. If there is no activity for 10 minutes, then
the Telnet session will close.

Web Browser Interface

The MR9600-100 can be monitored and controlled from a World Wide Web browser such as Netscape
Navigator version 2.0 or later, or Microsoft Internet Explorer version 3.0 or later.

Two interfaces are available: an HTML framed interface (in which the browser screen is split into separate
frames) and a non-framed interface. To use the framed interface, type the following URL in your browser’s
URL entry line and press E

http://111.222.333.444/mmm/main.html

For the non-framed interface, use the following URL:

NTER:

http://111.222.333.444/mmm/standard.html

In both examples, 111.222.333.444 represents your card’s IP address.

Logging In

Whenever you access the MR9600-100 for the first time during a browser session, you will be prompted for
a user ID and password. You must log in as someone of security level operator or higher to get access to the
Web interface.

Both the framed and the non-framed interfaces present logged-in users with a list of available views
(Framed or Standard), a list of operations, and a list of information views. These are all available via
hypertext links.

Getting Modem Information

In each interface the same information is available in table format. There are tables of information about
modems, calls on modems, modem and system faults, and system version. In the framed version these
tables appear in frames on a single HTML page; in the non-framed version each table appears on a
separate HTML page.

Controlling Modems

3 Operation

In either interface, the user can reset modems, set modems in or out of service, and configure modems.
When the user selects the hot link for an operation, a form appears in which the user can enter in list
format (e.g., 1A:3C,15B) the modems that are to have the desired operation performed on them. The
operation is performed when the user selects the action button (e.g., Config if the user is configuring
modems).

Web Interface Limitations

The Web interface does not provide a full management interface. Full management is provided by our
MultiModemManager software, or through the use of a third party SNMP manager. However, once the
system is set up, most management can be done using the Web browser interface.

FTP Interface

FTP (File Transfer Protocol) is a standard Internet protocol that allows the transfer of files between two
systems connected to a TCP/IP network, such as the Internet. The MR9600-100 acts as an FTP server so
that FTP clients can send and receive files to and from it.

You need FTP to transfer configuration files (*.cfg) to and from your system. If you plan to use
MultiModemManager security, you need FTP to transfer security files (*.db) to and from your system. If
you wish to analyze event information, you also need FTP to transfer event files (*.hr) from the MR9600­100 to a management computer where you can run the Statistical Analyzer on them.

Note: When logging in, you must use the Supervisor user name and password.
