Extend the Distance of Ethernet
Each CM2xx series media and rate converter line
card features a 10/100TX twisted pair port and a
100FX optical port. The twisted pair port has an
RJ-45 connector and a maximum operating
distance of 100 meters (328 feet) when
connected to either an Ethernet or Fast Ethernet
device. Depending on the model, the media and
rate converter line cards can operate in multi-
mode or single-mode fiber over various distances
up to 40km.The range support both dual fiber
pair transmission, and single fiber transmission,
allowing network administrators to build highly
cost-effective network, when considering the costs
of terminating fiber cables.These cards can
operate at half and full-duplex.
The AT-CM201 fiber optic port has a multi-mode
dual fiber ST connector and a maximum operating
distance of 2km (1.24 miles).
The AT-CM202 fiber optic port has a multi-mode
dual fiber SC connector and a maximum
operating distance of 2km (1.24 miles).
The AT-CM202/1 fiber optic port has a single-mode
dual fiber SC connector and a maximum operating
distance of 15km (9.32 miles).
The AT-CM202/2 fiber optic port has a single-mode
dual fiber SC connector and a maximum operating
distance of 40km (24.85 miles).
The AT-CM212A/1 fiber optic port has a single-
mode, single fiber SC connector and a maximum
operating distance of 15km (9.32 miles), and is
paired with the AT-CM212B/1.
The AT-CM212B/1 fiber optic port has a single-
mode single fiber SC connector and a maximum
operating distance of 15km (9.32 miles), and is
paired with the AT-CM212A/1.
The AT-CM212A/2 fiber optic port has a single-
mode, single fiber SC connector and a maximum
operating distance of 40km (24.85 miles), and is
paired with the AT-CM212B/2.
The AT-CM212B/2 fiber optic port has a single-
mode single fiber SC connector and a maximum
operating distance of 40km (24.85 miles), and is
paired with the AT-CM212A/2.
IEEE 802.3ah (OAM) Remote
Management
All the CM2xx series of line cards support IEEE
802.3ah (OAM) (Operations, Administration, and
Maintenance), allowing a remotely deployed line
card to be configured and monitored from the
central location using in-band signalling.This
signalling does not interfere with normal traffic
carried by the line cards.This functionality can
seriously reduce the maintenance costs for service
providers, by allowing them to determine the
nature of remote faults without having to dispatch
a maintenance engineer.
Flexible Deployment
The CM2xx series of line cards can be installed in
the complete range of Converteon
TM
chassis,
allowing them to be deployed in a stand-alone
fashion (AT-CV1000), or in a multi-slot chassis 
(AT-CV1200 and AT-CV5000). When deployed
with no management module, all the line cards
operate in an unmanaged mode. When deployed
with a management module in a multi-slot chassis,
line cards installed in the same chassis and also
line cards connected to the chassis can be
managed via RS232,Telnet or SNMP.
In unmanaged mode, the line cards can be easily
configured using DIP switches, where as in a
managed chassis, all the configuration can be
performed remotely.
Whatever the chassis, the line cards can be hot
swapped providing the network manager with a
mechanism to simply perform
moves/adds/changes without having to power
down other parts of the network.
Hassle Free Support
All Allied Telesis Ethernet media converter line
cards have a limited lifetime warranty and free
technical support, ensuring trouble-free installation.
MissingLink
TM
and 
Smart MissingLink™ (SML)
The MissingLink
TM
(ML) feature allows the ports
on the media converter blade to pass the ‘Link’
status of their 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, it shuts down the connection to the other
port, thus notifying the node that the connection
has been lost.The Smart MissingLink
TM
(SML)
feature provides the same function as
MissingLink
TM 
with one additional feature that
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.These features allow network
administrators to quickly troubleshoot network
problems.
Link Test, MissingLink
TM
, and 
Smart MissingLink
TM
Functions
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.
MissingLink
TM
The MissingLink
TM
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.
Smart MissingLink
TM
The Smart MissingLink
TM
feature performs exactly the same
function as MissingLink
TM
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).
