Introduction
The AT-DMC1000/100 Series Desktop Mini Media Converters include the
following models:
AT-DMC1000/SC
AT-DMC1000/ST
AT-DMC1000/LC
AT-DMC100/SC
AT-DMC100/ST
AT-DMC100/LC
The AT-DMC1000/100 Series Desktop Mini Media Converters are
designed to extend the distance of your network by interconnecting LAN
devices that are physically separated by large distances.
These media converters:
Provide a smaller-sized space-saving alternative that allows
enterprises to connect 1000Mbps copper networks to 1000Mbps
fiber networks (AT-DMC1000/SC, AT-DMC1000/ST, and
AT-DMC1000/LC) or connect 100Mbps copper networks to
100Mbps fiber networks (AT-DMC100/SC, AT-DMC100/ST, and
AT-DMC100/LC): This offers a cost-effective method for
integrating fiber-optic cabling into a 100/1000 UTP environment.
Operate at 1000Mbps full duplex (AT-DMC1000/SC,
AT-DMC1000/ST, and AT-DMC1000/LC) or 100 Mbps full duplex
(AT-DMC100/SC, AT-DMC100/ST, and AT-DMC100/LC).
Can be installed on a desktop or can optionally be wall mounted:
easy to install and does not require any software configuration or
management.
Note
Wall-mounting equipment is ordered separately as a five-pack
package: five mounting brackets for five media converters.
In addition:
Optional Smart MissingLink™ (SML) may be enabled or disabled
using a DIP switch.
Powered via a Micro-B USB 5VDC connector. Can be powered
from a PC USB port or with the optional AC/DC power adapter.

100Base-FX fiber-optic port
Auto Negotiation and Auto MDI/MDI-X on 100Base-TX twisted-pair
port. The twisted-pair port will auto-negotiate to 100Mpbs, full
duplex operation.
Support for Jumbo frames up to 16kB
LEDs for unit and port status
SML DIP switch for activating the SML feature which notifies end
nodes of connection failures
Micro-B USB 5VDC connector

Chapter 1: Overview

Twisted-Pair Port Here are the basic features of the twisted-pair (copper) port:
1000Base-T (AT-DMC1000/SC, AT-DMC1000/ST, AT-DMC1000/
LC) or 100Base-TX (AT-DMC100/SC, AT-DMC100/ST,
AT-DMC100/LC) compliant
IEEE 802.3u Auto-Negotiation compliant
Auto MDI/MDI-X
100 meters (328 feet) maximum operating distance
RJ45 connector
Fiber Connection The AT-DMC1000/100 Series media converters support the following
transceiver fiber connections:
The AT-DMC1000/SC has a fixed dual fiber SC 1000-X
connection.
The AT-DMC1000/ST has a fixed dual fiber ST 1000-X connection.
The AT-DMC1000/LC has a fixed dual fiber LC 1000-X connection.
The AT-DMC100/SC has a fixed dual fiber SC 100-X connection.
The AT-DMC100/ST has a fixed dual fiber ST 100-X connection.
The AT-DMC100/LC has a fixed dual fiber LC 100-X connection.
For the maximum operating distance, refer to Table 9 on page 58.
Auto MDI/
MDI-X
An RJ45 twisted-pair port on a 100 Mbps Ethernet network device can
have one of two possible wiring configurations: MDI or MDI-X. The RJ45
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.
The media converter features Auto MDI/MDI-X. The twisted-pair port
automatically determines the configuration of the port on the device to
which it is connected and then configures itself appropriately.
For example, if a port on a media converter is connected to a port on a
bridge, which is typically wired as MDI, the port on the media converter
automatically configures itself as MDI-X.
This feature allows you to use a straight-through cable when connecting
any type of device to the media converter, regardless of the wiring
configuration of the port on the device.
