AT-MC1008 Series Installation Guide
1000Base-TX Twisted Pair Port
Each AT-MC1008 Series converter features one fixed 1000 Mbps twisted
pair port. The features of the twisted pair ports are described below.
Type of Connector
The twisted pair ports on the AT-MC1008 Series converters feature
8-pin RJ-45 connectors. The port uses all eight pins when operating at
1000 Mbps. For port pinout details, refer to “RJ-45 Twisted Pair Port
Pinouts” on page 54.
Port Speed
The twisted pair port on the AT-MC1008 Series converters operates at a
fixed speed of 1000 Mbps.
Duplex Mode
Duplex mode refers to how an end-node receives and transmits data. If
an end-node can receive or transmit data, but not both simultaneously,
the end-node is operating in half-duplex mode. If an end-node can both
receive and transmit data simultaneously, the end-node is said to be
operating in full-duplex mode. Naturally, an end-node capable of
operating in full-duplex can handle data much faster than an end-node
that can only operate in half-duplex mode.
The twisted pair port on the AT-MC1008 Series converters is IEEE
802.3u compliant and advertises only 1000 Mbps and full duplex
capability.
Maximum Distance
The twisted pair port on the AT-MC1008 Series converters have a
maximum operating distance of 100 meters (328 feet).
Type of Cabling
The twisted pair port requires Category 5 or Enhanced Category 5 (5E)
100 ohm shielded or unshielded twisted pair cabling.
17
Chapter 1: Overview
Table 2 lists the twisted pair port cabling specifications.

SpeedType of Cable
Maximum
Operating
Distance
1000 MbpsCategory 5 or Category 5E
(Enhanced) 100 ohm shielded and
unshielded twisted pair cable
100 m (328 ft)
Auto MDI/MDI-X
The twisted pair port on the AT-MC1008 Series converter is auto-MDI and
IEEE 802.3ab-compatible. Consequently, you can use either a straightthrough or crossover twisted pair cable when connecting any network
device to a port.
Port Pinouts
For the port pinouts when the ports are operating at 1000 Mbps in the
MDI configuration, refer to Table 7, “MDI and MDI-X Pin Signals
(1000Base-TX),” on page 54.

AT-MC1008 Series Installation Guide
1000Base Fiber Optic GBIC Slot on the
AT-MC1008/GB Converter
The AT-MC1008/GB converter features one GBIC slot on the front panel.
The GBIC slot can accommodate one GBIC transceiver.
The fiber optic GBIC slot on the AT-MC1008/GB converter features one
GBIC pluggable transceiver, as shown in Figure 5.
Figure 5. Example of a GBIC Transceiver
When you attach a fiber optic cable to a GBIC transceiver, be sure to
observe the following guidelines:
You should verify that you are using the appropriate type of fiber optic
cabling. For GBIC cabling specifications, refer to the installation guide
provided with the transceiver.
You should verify that the operating specifications of the remote fiber
optic port are compatible with the GBIC transceiver. For example, you
cannot connect a fiber optic GBIC transceiver with a maximum
distance of 40 kilometers and an operating wavelength of 1550
nanometers (nm) to a remote fiber optic port with an maximum
distance of only 10 kilometers and an operating wavelength of 1310
nm.
Be sure that the cable connectors is firmly locked into place in the
GBIC slot.
Note
For a list of the GBIC transceivers supported can be used with the
AT-MC1008/GB converter, contact your ATI sales representative.

AT-MC1008 Series Installation Guide
MODE Push Button
The MODE push button is used to toggle between the three operation
modes: Link Test (LT), MissingLink (ML), and Smart MissingLink (SML).
This button is located on the front panel. The button cycles through these
three modes with each push.
To select between the three modes, use a pointed object such as a pen to
depress the push button.
Link Test
The link test is a fast and easy way for you to test the connections
between the media converter ports 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 or end-node where the problem
resides.
To perform a link test, toggle the MODE selection button until the LT LED
is green. The LINK LEDs for the ports should now be green, indicating
that they were able to establish a link with their end-nodes. If a LINK LED
is off, the port could not establish a link. Refer to “Troubleshooting” on
page 51 for suggestions on how to isolate the problem.
Note
The link test is a normal mode of operation; therefore, performing a
link test does not interfere with a media converter’s ability to pass
network traffic.
MissingLink
The MissingLink feature enables the two ports on the media converter to
pass the “Link” status of their connections to each other. When the media
converter detects a loss of connection to an end-node, the media
converter shuts down the connection to the other port, thus notifying the
end-node that the connection has been lost.
For example, if the twisted pair cable to the 1000Base-T port on the
media converter were to fail, the unit would respond by dropping the link
on the 1000Base-FX fiber optic port. In this way, the media converter
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
21
Chapter 1: Overview
fiber optic cabling, the unit would drop the link to the twisted pair port.
The value to this type of network monitoring and fault notification is that
some network devices connected directly to the AT-MC1008 media
converter can be configured to take a specific action in the event of the
loss of connection on a port. In some cases, a network device may be
capable of being 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
MissingLink and Smart MissingLink are disabled when you perform
a link test. Consequently, to ensure that MissingLink or Smart
MissingLink is enabled on the media converter during normal
network operations, always set the MODE push button so that the
ML or SML LED is green.
Smart MissingLink
The Smart MissingLink feature performs exactly the same function as
MissingLink with one additional feature. When a link is lost on a port, the
LINK LED of the port which still has a valid connection to its end-node
starts to blink. This allows you to quickly determine which port still has a
valid connection (LINK LED blinking) and which port has lost its
connection (LINK LED off).
For example, if the network twisted pair cable to the 1000Base-TX port on
the converter were to fail, the LINK LED on the 1000Base fiber optic port
will blink, indicating a failed connection on the twisted pair port. If the
failure had started with the fiber optic cabling, the LINK LED on the
twisted pair port would blink.
The value to this type of network monitoring and fault notification is so
that you can quickly see which port has failed and troubleshoot your
network accordingly.

Chapter 1: Overview
Back-to-Back Topology
In some network configurations you may want to interconnect two media
converter in what is referred to as a back-to-back topology. In this
topology, the media converter not only extend the distance of your
network but also convert the fiber optic cable from twisted pair to fiber
optic and back again. Figure 10 illustrates one AT-9424T/SP switch at
each campus. The switches are interconnected by two AT-MC1008/SP
media converters which provide a connection of up to 15 kilometers (9.32
miles). The 1000Base-T twisted pair ports on the media converters are
connected to the twisted pair ports on the switches, while the 1000Base
SFP ports on the two AT-MC1008/SP media converters are directly
connected to each other.
Note
When using two media converters back-to-back, you must set both
converters to the same mode (in example, the first media converter
is set to Smart MissingLink mode; then the second converter must
also be set to Smart MissingLink mode.)
