Chapter 1

Overview

The AT-MC13 and AT-MC14 media converters are designed to extend the
distance of your network over large distances by interconnecting twisted pair
cabling to single-mode or multimode fiber optic cabling.

These media converters feature a 10Base-T twisted pair port and a 10Base-F
fiber optic port. The twisted pair port has an RJ-45 connector and a maximum
operating distance of 100 meters (328 feet). The fiber optic port has an ST or
SC connector, depending on the model, and a maximum operating distance of
2 kilometers (1.2 miles). These media converters operate at 10 Mbps and
feature half- or full-duplex operation.

The AT-MC13 and AT-MC14 media converters can be used on a desktop or in
an AT-MCR12 chassis. These media converters are easy to install and do not
require software configuration or management.

Key Features

The media converters have the following key features:

q Twisted pair port with an RJ-45 connector

q Fiber optic port with a ST or SC connector

q LEDs for unit and port status

q Half- or full-duplex mode operation

q MissingLink notifies end-nodes of link failures

q NML/LNK TST button that performs a link test on the media

converter

q MDI/MDI-X switch that eliminates the need for a crossover cable

q External AC/DC power adapter

q Standard size for desktop use or in an AT-MCR12 rackmount chassis

Twisted Pair Port

The 10Base-T port on the AT-MC13 and AT-MC14 media converters have an
RJ-45 connector and is designed to operate with Category 5 or better shielded
twisted pair cable.

Fiber Optic Port

The 10Base-F port on the AT-MC13 and AT-MC14 media converters have
either an SC or ST connector designed to operate with multimode fiber optic
cabling. This port has a maximum operating distance of 2 kilometers (1.2
miles) using 62.5/125 micron multimode fiber optic cable.

MDI/MDI-X Switch

An RJ-45 port on a 10 Mbps Ethernet network device can have one of two
possible wiring configurations: MDI or MDI-X. The RJ-45 port on a PC, router
or bridge is typically wired as MDI, while the twisted pair port on a switch or
hub is usually MDI-X.

To connect two 10 Mbps network devices together that have dissimilar port
wiring configurations, such as MDI to MDI-X, you use a straight-through cable.
To connect two network devices that have RJ-45 ports with the same wiring
configuration, such as MDI to MDI, you use a crossover cable.

The RJ-45 port on the AT-MC13 and AT-MC14 media converters feature an
MDI/MDI-X switch. You can use this switch to configure the twisted pair port
on the media converter as either MDI or MDI-X, thus eliminating the need for
a crossover cable regardless of the type of network device you are connecting to
the unit.

NML/LNK TST Button

The NML/LNK TST (Normal MissingLink/Link Test) button allows you to
perform a link test on the ports on the media converter. This button also allows
you to activate the MissingLink feature on the unit. The MissingLink and Link
Test features are describe below.

MissingLink. The MissingLink feature activates the ports on the media

converter to pass the “Link” status of t heir connections to each other. When the
media converter detects a problem with one of the ports, such as the loss of
connection to a node, the media converter shuts down the connection to the
other port, thus notifying the node that the connection has been lost.

For example, if the network twisted pair cable to the AT-MC14 were to fail, the
media converter would respond by dropping the link on the fiber optic port. In
this way, the AT-MC14 notifies the end-node connected to the fiber optic port
that the connection on the twisted pair port has been lost. If the failure had
started with the fiber optic cabling, the media converter would drop the link to
the twisted pair port.

The value to this type of network monitoring and fault notification is that some
hubs and switches can be configured to take a specific action in the event of the
loss of connection on a port. In some cases, the unit can be configured to seek a
redundant path to a disconnected end-node or send out a trap to a network
management station, and so alert the network administrator of the problem.

Note

The MissingLink feature is disabled when you perform a link test with
the NML/LNK TST button. Consequently, to ensure that the
MissingLink feature is activated on the media converter, always set the
button to the NML (IN) position during normal network operations.

Link Test. A link test is a fast and easy way for you to test the connections

between the ports on the media converter and the end-nodes that are connected
to the ports. If a network problem occurs, you can perform a link test to
determine which port is experiencing a problem, and so be able to focus your
troubleshooting efforts on the cable and end-node where the problem resides.

A link test is performed when the NML/LNK TST button is in the LNK TST
(OUT) position.

Note

Performing a link test does not interfere with a media converter’s ability
to pass network traffic.
