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.

IEEE 802.3ah (OAM) Remote
Management
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 chassis,
allowing them to be deployed in a stand-alone
fashion (AT-CV1000), or in a multi-slot chassis
(AT-CV1203 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.

MissingLink and Smart MissingLink (SML)
The MissingLink (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. Smart MissingLink (SML)
is 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.

Smart MissingLink Functions
Smart MissingLink 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
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

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).
