Allied Telesis CONVERTEON AT-CM212A/1 仕様

CM2xx SERIES

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.

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.

| Converteon Series Line Cards

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.

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 offer free technical support, ensuring

trouble-free installation.

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.

Link Test, MissingLink, and

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

lost.

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).
