Overview  Ethernet over VDSL2 Converter

 High-Performance of Ethernet over VDSL Solution
Up to 100/100Mbps asymmetric data rate within 300m and 30/10Mbps for 1km long range connections provides ultra-high performance to the pervasive telephone line network. The 
CBT1000 is an Ethernet-over-VDSL2 product with high performance. It is based on two core networking technology, Ethernet and VDSL2 (Very-high-data-rate Digital Subscriber Line 2). This technology offers the absolutely fastest data transmission speeds over existing copper telephone lines without the need of rewiring.

Implements with Existing Telephone Copper Wires
The CBT1000 Long Reach Ethernet (LRE) converter has a switching architecture with one RJ-45 Ethernet port and two RJ-11 phone jacks –one for VDSL connection and one for POTS (Plain Old Telephone Service) connection. To share the existing phone line with POTS or ISDN, the 
CBT1000 has built-in POTS splitter. It is no need to replace the existing copper wiring. And just plug into the existing RJ-11 telephone jack for connecting a high-performance VDSL2 network. This capability is ideal for use as an Ethernet extender to an existing Ethernet network.

Delivers High-Demand Services Connectivity for ISP / Triple Play Devices
With enough bandwidth, the 100/100Mbps symmetric capability of 
CBT1000 enables many Multi-Media services to come true on local Internet, such as VOD (Video on Demand), Voice over IP, Video phone, IPTV, Internet caching server, distance education, and so on. The CBT1000 provides the excellent bandwidth to satisfy the triple play devices for home entertainment and communication.

Easy Installation
The Converter is plug and play without any software to configure and also fully compliant with all kinds of network protocols. Moreover, the rich diagnostic LEDs on the front-panel provide the operating status of individual port and the whole system. There are two selectable models of the 
CBT1000. One is used for client side (CPE) and the other is central side (CO).To setup one pair of converters for point-to-point connection, one set must be CPE mode and the other one is CO mode via a built-in DIP Switch.


 Ethernet Distance extension
CBT1000 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 maximum 100/100Mbps data rate. Telephone service can still be used while the modems are in operation. These two charts listed below are typical applications for the Ethernet over VDSL converter.

MTU / MDU / Hospitality Solution
CBT1000 is the best solution to quickly provide cost-effective, high speed network services to multi-unit buildings, such as residential (multi-dwelling units) and commercial (multi-tenant units) buildings, hotels and hospitals. By utilizing the existing telephony infrastructure, network installation is straightforward and requires no new wiring. With up to 100/100Mbps, Video on Demand, IP telephony and various broadband services can be easily provisioned.

Last Mile of FTTx deployment
The CBT1000 is a great and ideal solution for FTTx (Fiber to the Building, Fiber to the Campus or 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 to the buildings and customers´ home. The 10/100Mbps port of CBT1000 can be directly connected to a PC or to Ethernet devices such as Ethernet Switches and Broadband 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 in the Internet and the whole building could share the Internet to the wider area network with minimum cost.
