2178HSEE-4 Ethernet Extender


4-port high speed ethernet extender


100/100Mbps Downstream / Upstream, high Performance Ethernet over VDSL Solution The Data Connect 2178HSEE-4 is an Ethernet-over-VDSL2 Bridge with high performance. It is designed based on two core networking technology, Ethernet and VDSL2 (Very-high-data rate Digital Subscriber Line 2). The VDSL2 technology offers absolutely fastest data transmission speed over existing copper telephone lines without the need of rewiring. The Data Connect 2178HSEE-4 supports ultra-high performance to the pervasive telephone line network with up to 100/100Mbps symmetric data rate within 300m and 20/4Mbps for 1.4km long range connections.

Implements with Existing Telephone Copper Wires The Data Connect 2178HSEE-4 is also a Long Reach Ethernet (LRE) Bridge providing four RJ-45 Ethernet ports and two RJ-11 phone jacks, in which one or VDSL connection and the other one is for POTS (Plain Old Telephone Service) connection. The Data Connect 2178HSEE-4 has built-in POTS splitter to share the existing phone line with POTS; therefore it is no need of replacing the existing copper wiring. Just plug the Data Connect 2178HSEE-4 into the existing RJ-11 telephone jack and high-performance VDSL2 network can be connect connected. The Data Connect 2178HSEE-4 is ideal to be used as an Ethernet extender to an existing Ethernet network.

Deliver High-Demand Service Connectivity for ISP / Triple Play Devices The Data Connect 2178 HSEE-4 provides excellent bandwidth to satisfy the triple play devices for home entertainment and communication. With the capability of 100/100Mbps symmetric data transmission, the Data Connect 2178HSEE-4 enables many Multi-Media services to work on local Internet, such as VOD (Video on Demand), Voice over IP Video phone, IPTV, Internet caching server, distance education and so on.

Easy & Flexible Installation The Ethernet-over-VDSL2 Bridge is plug-and-play design and fully compatible with all kinds of network protocols. Moreover, the operating status of each individual port and the whole system can be watched via the rich diagnostic LEDS on the front panel. The Data Connect 2178HSEE-4 offers two modes CPE and CO, for application: CPE mode is used at client side on CO mode is at central side. The CPE or CO mode can be adjusted by using a built-in DIP switch. For point-to-point connection, a CPE mode Data Connect 2178HSEE-4 and CO mode Data Connect 2178HSEEE-4 must be setup as one pair of converters to perform the connection.

Provide Superior Upstream and Downstream Transmission Performance The Data Connect 2178HSEE also define symmetric band plan for the transmission upstream and downstream signals; the band plan performs higher transmission quality in short range for short range for central side (CO) in symmetric mode. In all, when the Data Connect 2178HSEE-4 is profile 17a operation mode, it provides long distance transmit with Ultra-high performance to pervasive telephone line network, and when the VC-234 is in 30a operation mode, it gives short distance transmits with upstream and downstream transmission giving wire speed performance.

Ethernet Distance Extension Two 2178HSEE-4 acting as a standalone pair good for Ethernet distance extension over existing telephone wires. With just one pair of AWG-24 copper wire, you can easily connect two Ethernet networks together with the data rate of maximum 100/100Mbps. The telephone service can still be used while the 2178HSEE-4 CO/CPE is in operation. The two solutions listed below are typical applications for the Ethernet over VDSL2 Bridge.


MTU / MDU Hospitality Solution The Data Connect 2178HSEE-4 is a perfect solution to quickly provide cost-effective yet high speed network services to multi-unit buildings such as residential building (multi-dwelling units), commercial (multi-tenant units), buildings, hotels or hospitals. By utilizing the existing telephony infrastructure, network installation is straight ward and requires no new wiring. With up to 100/100Mbps transmission, Video on Demand, IP telephony and various broadband services can be easily provided.


Last Mile of FTTx Deployment
The Data Connect 2178HSEE-4 is an ideal solution for FTTx (Fiber to the Building, Fiber to the Campus of Fiber to the Node) applications. It supports high bandwidth VDSL2 over existing telephone wires in the “last mile” from the ISP / Telecom / Service provider’s fiber node the buildings and customers houses. The 10/100Mbps ports of The Data Connect 2178HSEE-4 can be directly connected to a PC or to Ethernet devices such as Ethernet Switches or Broadband Routers. It is excellent for phone line network built under Internet because every room or house could use the existing phone line to transmit data through the Internet and the whole building could share the internet to the wider area network with minimum cost.
