High Performance Gigabit Ethernet over Phone Wire Solution
PLANET VC-234G, a new-generation and high-performance Gigabit Ethernet-over-VDSL2 Converter, works well with a pervasive telephone line network with a symmetric (downstream/upstream) data rate of up to 150/150Mbps (G.INP, Sym, 8dB) over a distance of 300m and 20/12Mbps over a long distance of 1.4km. It is based on the two-core networking technology, Gigabit Ethernet and VDSL2 (Very-high-data-rate Digital Subscriber Line 2). The VDSL2 technology offers absolutely the fastest data transmission speed over the existing copper telephone lines without the need of rewiring.
With integrated support for the ITU-T’s new G.993.5 vectoring technology, the VC-234G works in conjunction with vectoring-enabled DSLAMs to remove crosstalk interference and improve maximum line bandwidth across the existing copper telephone infrastructure.
Implementing with Existing Telephone Copper Wires
The VC-234G is also a Long Reach Ethernet (LRE) Bridge providing four RJ45 Ethernet ports and two RJ11 phone jacks, in which one is for VDSL connection and the other one is for POTS (Plain Old Telephone Service) connection. The VC-234G has a built-in POTS splitter to share the existing phone line with POTS; therefore, there is no need to replace the existing copper wiring. Just plug the VC-234G into the existing RJ11 telephone jack and a high-performance VDSL2 network can be connected. The VC-234G is ideal to be used as an Ethernet extender to an existing Ethernet network.
Delivering High-demand Service Connectivity for ISP/Triple Play Devices
The VC-234G provides excellent bandwidth to satisfy the triple play devices for home entertainment and communication. With the capability of 200/100Mbps (G.INP, Asym, 8dB) asymmetric data transmission, the VC-234G 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 and Flexible Installation
The Ethernet-over-VDSL2 Converter comes with a Plug-and-Play design and is 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 VC-234G offers two modes, CPE and CO, for application -- CPE mode is used at client side and CO mode is at central side. The CPE or CO mode can be adjusted by using a built-in DIP switch. For the point-to-point connection, a CPE mode and a CO mode must be set up as one pair of converters to perform the connection.
For those ISPs that still provide ADSL broadband service, the VC-234G can support a downstream rate of up to 24Mbps and an upstream rate of 1Mbps with the ADSL2+ technology. The VC-234G can also be directly switched over to VDSL2 after the network upgrade.
Ethernet Distance Extension
Two VC-234G devices, acting as a standalone pair, are good for Ethernet distance extension over the existing telephone wires. With just one pair of AWG-24 copper wires, you can easily connect two Ethernet networks together with a maximum data rate of 200Mbps. The telephone service can still be used while the VC-234G CO/CPE is in operation. The two solutions listed below are typical applications for the Ethernet over VDSL2 Bridge.
The VC-234G is a perfect solution to quickly providing cost-effective yet high-speed network services to multi-unit buildings such as residential buildings (multi-dwelling units), 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 200/100Mbps (G.INP, Asym, 8dB) transmission, VoD, IP telephony and various broadband services can be easily provided.
Last Mile of FTTx Deployment
The VC-234G is an ideal solution for FTTx (Fiber to the Building, Fiber to the Campus or Fiber to the Node) applications. It supports high-bandwidth VDSL2 over the existing telephone wires in the “last mile” from the telecom or Internet service provider’s fiber node to the buildings and customers’ apartments. The 10/100/1000Mbps port of the VC-234G can be directly connected to a PC or Ethernet devices such as Ethernet switches or broadband routers. It is excellent for phone line network built under Internet because every room or house can use the existing phone line to transmit data through the Internet and the whole building can share the Internet to the wider area network at a minimum cost.
