DZS EtherXtend SHDSL Ethernet Access Devicezhone etherxtend 2200 ds3

EtherXtend DS3 Ethernet Access Device with up to 2 bonded DS3s and an integrated 4 port 10/100 switch

ETHX-2214-DS3, ETHX-2224-DS3


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.

The EtherXtend 2200 Series of DS3 EADs  feature an integrated 4-port 10/100 Ethernet switch and either one or  two DS3 ports, each capable of delivering up to 45 Mbps of bandwidth. On a 2-port device, the two DS3 ports can be bonded together to provide 90 Mbps data rates. The loop bonding technology used by the EtherXtend  2200 Series DS3 EADs is the industry-leading, Net-to-Net (N2N) loop  bonding protocol.

To maximize the total bandwidth  available, the ETHX-22x4-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 (including the overhead bits normally used for various DS3 framing formats). Therefore, unframed DS3 circuits (rather than M13 or C-bit Parity DS3 frame formats) are to be used with ETHX-22x4-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. By combining unframed DS3s with N2N  loop bonding protocols, the ETHX-22x4 devices offer automatic,  efficient, resilient, and configuration-free deployment with greater  total throughput capacity than a traditional DS3 circuit.

The EtherXtend DS3 EADs also supports  many advanced network features, including: 802.1Q VLANs, built-in  security features, advanced QoS and sophisticated bandwidth management  and control features available only with DZS's unique Multimedia  Traffic Management (MTM) capabilities.
