Zhone's EtherXtend 2100 SHDSL series of Ethernet Access Devices (EADs) allows Carriers, CLECs, ISPs and PTTs to deliver Ethernet services to their customers simply, quickly and cost-effectively over existing copper plant. Intended for deployment at end-users' locations, these devices allow delivery of Ethernet services using SHDSL.bis transport protocols.The EtherXtend 2100 series of EADs represents the next generation of simple, configuration-free, plug and play Ethernet over Copper Network Extenders available from Zhone Technologies. By employing Zhone's pre-standards based, Net-to-Net (N2N) bonding protocols, these units continue to build on the simplicity and popularity of Zhone's SHDSL Network Extenders (SNE) family of products, while extending the data rates available to a full 5.7Mbps per pair, in compliance with the ITU-T G.991.2 SHDSL.bis standards.The EtherXtend 2100 SHDSL products can interoperate with each other in a point-to-point configuration. Where several of these devices must home on a common central office (CO) location, CO aggregation can be achieved using the ESIM5700-48 line card of Zhone's IP-DSLAM (IPD) platform. Alternatively, service providers can use Zhone's Single Line Multi-Service (SLMS) family of products as aggregation devices for the ETHX-2112 EADs.What differentiates Zhone's EtherXtend 2112 EADs from competing vendors' offerings is the simplicity and efficiency with which Ethernet services can be deployed over bonded loops with a minimum of fuss and/or operational complexity - only made possible by the automatic, configuration-free, "plug and play" operation of Zhone's EtherXtend SHDSL product line.
