The EtherXtend 2200 series of DS3 Ethernet Access Devices (EADs) allows Carriers, ISPs and PTTs to deliver Ethernet services to virtually anywhere, using standard unframed/unstructured DS3 circuits. These units permit the efficient and reliable delivery of Ethernet on a single DS3 or on a bonded pair of DS3 circuits. With the ability to provide up to 90 Mbps of data transport, near native 10/100BT Ethernet speeds can be achieved to deliver demanding LAN, WAN, and IP-based services to an increasingly sophisticated generation of small and medium-sized business customers.
The EtherXtend 2200 series of DS3 EADs can be deployed at any location that is served by one or more unframed/unstructured DS3s; and because they use Ethernet instead of ATM or Frame Relay, they are optimized for the delivery of high speed Internet Protocol (IP) traffic, including applications requiring high bandwidth, low latency transport mechanisms such as video conferencing, digital video surveillance, IP telephony and much more.
To maximize the total bandwidth, the ETHX-2214-DS3 devices operate in a DS3 framer-bypass mode whereby the Ethernet traffic is mapped onto the entire 44.736 Mbps of each DS3 facility. Therefore, unframed DS3 circuits are to be used with ETHX-2214-DS3 network extenders, and any intermediary DS3 transport or multiplexing equipment must be set to regenerate the entire 44.736 Mbps of bandwidth without modifying or omitting any of the bits typically associated with overhead in framed DS3 facilities.
