The AT-CM70S is a 10/100 Mbps Ethernet copper-to-fiber media converter line card with Time Division Multiplexing (TDM) (T1/E1) transport, in addition to regular Ethernet traffic along with OAM link management capability. This line card offers support for 1.544 Mbps (T1) and 2.048 Mbps (E1) services - with complete synchronization for toll-quality transport of voice, video, and data. It also accommodates traditional testing equipment currently used on SONET/SDH equipment for testing T1/E1 services.
The AT-CM70S line card can be installed in the Converteon Media Converter chassis, either the AT-CV5000 or the AT-CV1200. The line card features one small form-factor pluggable (SFP) transceiver slot, one copper twisted pair port, four T1/E1 ports, and one console (Mini-DIN) port. The SFP slot can accommodate one SFP transceiver that operates at a fixed operating speed of 100 megabits per second (Mbps). The twisted pair port has an RJ-45 connector with a maximum operating distance of 100 meters (328 feet) and operates at a speed of 10 or 100 Mbps. The line card is hot-swappable into and out of the chassis.
Expanding the bandwidth
Each AT-CM70S media converter card features 4 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 demultiplexes the single, and provides the five separate data streams.
The AT-CM70S line cards can be installed into a Converteon chassis, allowing them to be deployed into a stand-alone fashion, or into a multi-slot chassis. 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.
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 setup, test, and observe the remote devices without having to dispatch engineers.
Link testProduct Highlights
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.
