Chapter 1: Overview
Features
The AT-MCF2012LC and AT-MCF2012LC/1 Media
Converter Modules are designed to interconnect Fast
Ethernet networking devices over large distances by
transferring Fast Ethernet network packets between twisted
pair cable and fiber optic cable. The modules feature twelve
independent media converter channels with each channel
consisting of one 10/100Base-TX twisted pair port and one
100Base-FX fiber optic port. The fiber optic ports have a
maximum operating distance of 2 or 20 kilometers (km),
depending on the model.
The modules feature low latency to minimize the impact on
network performance along with cyclic redundancy check
(CRC) detection to prevent the propagation of incomplete or
fragmented packets on your network.

Note
The maximum operating distances of the fiber optic
ports assume full-duplex operation. A fiber optic port
operating in half-duplex mode will have a maximum
operating distance that is significantly less.
Note
The modules must be installed in an AT-MCF2000
product line chassis, such as the AT-MCF2000
chassis. For information on the availability of other
chassis models in the AT-MCF2000 product line,

Media Converter Channels
The AT-MCF2012LC and AT-MCF2012LC/1 modules have
twelve independent media converter channels. Each
channel forwards Fast Ethernet network traffic between one
10/100Base-TX twisted pair port and one 100Base-FX fiber
optic port.
The channels are predefined. Channel 1 consists of twisted
pair port 1 and fiber optic port 1 (as shown in Figure 4),
channel 2 of twisted pair port 2 and fiber optic port 2, and so
forth. The port assignments of the channels cannot be
changed.

Figure 4. Channel 1 on the Media Converter Module
Each channel operates independently of the other channels
on the same module and from channels on other modules in
the same chassis. As such, the traffic on the two ports of a
channel cannot crossover to the ports of another channel.
A channel uses “store and forward” to transfer packets
between its two ports. A packet is forwarded to the egress
port of a channel after it has been fully received and
buffered on the ingress port and checked for CRC errors.
Packets without a CRC error are forwarded to the egress
port where CRC is regenerated prior to the transmission of
the packet, while packets with CRC errors are discarded to
prevent their propagation on the network.

Chapter 1: Overview
Twisted Pair Ports
The twisted pair ports feature standard RJ-45 8-pin
connectors and operate at either 10 or 100 Mbps in either
half- or full-duplex mode. The ports use TIA/EIA 568-Bcompliant Category 3 or better cable for 10 Mbps operation
and Standard TIA/EIA 568-A-compliant Category 5 or TIA/
EIA 568-B-compliant Enhanced Category 5 (Cat 5e) cable
for 100 Mbps operation. The ports have a maximum
operating distance of 100 meters. For port pinouts, refer to
“10/100Base-TX Port Pinouts” on page 62.
The ports are IEEE 802.3u. compliant. They can
automatically set their speed and duplex mode with AutoNegotiation, which is the default setting. To disable AutoNegotiation and set the speed and duplex mode manually,
you must install the optional management module in the
chassis.
In order for Auto-Negotiation to work properly, the
networking device connected to a twisted pair port on the
module should also use Auto-Negotiation. Otherwise, a
duplex mode mismatch can occur. A twisted pair port using
Auto-Negotiation will default to half-duplex if it detects that
the port on the networking device is not using AutoNegotiation. If the other networking device is operating at a
fixed duplex mode of full-duplex, the result will be a duplex
mode mismatch with the port on the module operating at
half-duplex and the port on the networking device at fullduplex. This can reduce network performance.
If you plan to connect a networking device that can operate
only in full-duplex mode to a twisted pair port on the media
converter module, you should disable Auto-Negotiation on
the port on the module using the optional management
module and set the speed and duplex mode manually.
Alternatively, you can reconfigure the port on the
networking device to Auto-Negotiation or, if it does not
support that feature, to half-duplex mode.
The twisted pair ports on the media converter module also
feature auto-MDI/MDI-X which automatically adjusts the
wiring configuration of a twisted pair port to either MDI or
MDI-X, depending on the wiring configuration of the end
node. This feature allows you to use a straight-through
twisted pair cable regardless of the wiring configuration of
the port on the networking device.
