4 xT1/E1 + 10/100TX over SFP-based fiber line card
Overview
The AT-CM70S T1/E1 media converter line card is
designed to increase the capacity of an existing
point-to-point fiber network, by multiplexing up to
four T1/E1 TDM channels and one Fast Ethernet
channel over a single fiber interface. By the use of
a modular fiber SFP (mini-GBIC) uplink, installers
can easily deploy the AT-CM70S over a wide range
of fiber optics, including multi-mode, single-mode
and bi-directional fiber at distances up to 40km.
Expanding the Bandwidth
Each AT-CM70S media converter card features
four T1/E1 twisted pair interfaces, and one
10/100TX copper twisted pair interface. All five
data paths are multiplexed onto a single SFP-
based fiber interface, for transportation up to
40km. A second AT-CM70S blade at the remote
site de-multiplexes the single, and provides the
five separate data streams.
Deploying the AT-CM70S allows existing installed
fiber cables, carrying only a single T1 or E1 channel,
to be upgraded to carry more than four times the
amount of traffic, without having to install any new
fiber cable. All the T1/E1 channels are fully
independent, allowing a service provider to
expand the capabilitities of an existing fiber, whilst
providing WAN services to different customers.
Each T1 copper port has a maximum bit rate of
1.544Mbps, and a maximum line length of 6000ft
over 100 Ohm balanced cable.
Each E1 copper port has a maximum bit rate of
2.048Mbps, and a maximum line length of 2.5km
over 120 Ohm balanced twisted pair cable.
The 10/100TX Ethernet twisted pair port has an
RJ-45 connector and a maximum operating
distance of 100 meters (328 feet).
Flexible Deployment
The AT-CM70S line cards can be installed into a
Allied Telesis
Converteon chassis, allowing them to be deployed
into a stand-alone fashion (AT-CV1203), or into a
multi-slot chassis (AT-CV5000).When deployed in a
multi-slot chassis, the line cards can be unmanaged,
or managed with the inclusion of at least one
management card in the chassis. In unmanaged
mode, the line cards can be easily configured using
DIP switches, whereas 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.
OAM (Operation,Administration and
Maintenance)
The AT-CM70S supports IEEE 802.3ah OAM
features, allowing the device to be remotely
configured and maintained in-band from a locally
administered AT-CM70S.The local blade, used in
conjunction with a CPM management module,
allows network administrators to remotely set-up,
test, and observe the remote devices without
having to dispatch engineers.
Local Management Console
The AT-CM70S provides support for a local
management console.The local console on the
AT-CM70S allows full configuration in a AT-CV1203
or AT-CV5000 chassis when there is no CPM.
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.
Hassle Free Support
All Allied Telesis Ethernet media converter line
cards offer free technical support, ensuring
trouble-free installation.
