High Performance Ethernet over VDSL Solution The Data Connect 2178HSEPE is a High Speed Ethernet and POTS Extender 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 the absolutely fastest data transmission speeds over existing copper telephone lines without the need to rewiring. The Data Connect 2178HSEPE supports ultra-high performance to the pervasive telephone line network up to 100/55Mbps asymmetric data rate within 200m and 25/4Mbps for 1.6km long range connections.

Implements with Existing Telephone Copper Wires The Data Connect 2178HSEPE is also a Long Reach Ethernet (LRE) Extender provides one RJ-45 Ethernet port and two RJ-11 phone jacks, in which one is for VDSL connection and the other one is for POTS (Plain Old Telephone Service) connection. The Data Connect 2178HSEPE 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 2178HSEPE into the existing RJ-11 telephone jack and high performance VDSL2 network can be connected. It is ideal for use as Ethernet extender to an existing Ethernet network.

Delivers High Demand Services Connectivity for ISP I Triple Play Devices The Data Connect 2178HSEPE provides excellent bandwidth to satisfy the triple play devices for home entertainment and communication. With the capability of 100/55Mbps symmetric data transmission, the Data Connect 2178HSEPE enables many multi-media services to work on the local Internet, such as VOD (Video on Demand), Voice over IP, Video Phone, IPTV, Internet caching server, distance education and so on.

Easy Installation The Extender 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 diagnostics LEDs on the panel. There are two selectable models of the DCE 2178HSEPE on is used at client side (CPE) and the one is at central side (CO). The CPE or CO mode can be adjusted by using a built-in DIP switch. For point-to-point connection, a CPE mode on the DCE 2178HSEPE and a CO mode on the DCE 2178HSEPE must be setup as one pair of extenders to perform the connection.

Provide Superior Upstream and Downstream Transmission The Data Connect 2178HSEPE also defines asymmetric (Plan 998) and symmetric (Plan 997) band plans for the transmission of upstream and downstream signals. The featured band plan 997 provides the symmetric transmission on both downstream and upstream. On the other hand, the band plan 998 performs higher transmission quality in short range for central side (CO) in asymmetric mode. In all, when is in symmetric mode, it provides better upstream performance, and when the DCE 2178HSEPE is in asymmetric mode, it gives better downstream performance.



Ethernet Distance Extension Two Data Connect 2178HSEPE acting as a standalone pair is 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 100/55Mbps. Telephone service can still be used while the modems are in operation. The two solutions listed below are typical applications for Ethernet over VDSL extender.


MTU / MDU / Hospitality Solution
The Data Connect2178HSEPE is a perfect solution to quickly provide cast-effective yet high speed network services to multi-unit building such as residential buildings (multi-dwelling units), commercial (multi-tenant units) buildings, hotels or hospitals. By utilizing the existing telephony and various broadband services can be easily provisioned.


Last mile of FTTx Deployment
The Data Connect 2178HSEPE is an ideal solution for FTTx (Fiber to the building, Fiber to the Campus, and Fiber to the Node) applications it supports high bandwidth VDSL2 over existing telephone wires in the “last mile” from the ISP / Telecom / Service providers fiber node to the buildings and customers’ home. The 10/100MBps port of the DCE 2178HSEPE can be directly connected to a PC or to Ethernet devices such as Ethernet Switches or Bandwidth Routers. It is excellent for phone line network built by Internet because every room or house could use the existing phone line to transmit data through the Internet and whole building could share to Internet to the wider area network with minimum cost.
