200/200Mbps Downstream/Upstream, High-performance Gigabit Ethernet over Phone Wire Solution
PLANET VC-234G, a new-generation and high-performance Gigabit Ethernet-over-VDSL2 Bridge with the brand-new VDSL2 Super Vector 35b profile, works well with a pervasive telephone line network with a symmetric data rate of up to 200/200Mbps (G.INP, Sym, 8dB) over a distance of 200m and 25/16Mbps 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.
High-performance Ethernet over VDSL2 Transmission
Via the latest VDSL2 technology, PLANET VC-234G offers high-speed access to Internet, up to 200Mbps for both upstream and downstream data transmissions. With integrated support for the ITU-T’s new G.993.5 vectoring technology, the VC-234G
offers a stable yet high-speed point-to-point network access up to a duplex data transmission rate of 300Mbps. It provides 2 selective transmission modes — asymmetric mode or symmetric mode — for the transmission of upstream and downstream signals.
- Asymmetric mode – downstream up to 300Mbps and upstream up to 100Mbps
- Symmetric mode – downstream up to 200Mbps and upstream up to 200Mbps
The symmetric mode provides similar transmission rate on both downstream and upstream while the asymmetric mode performs higher transmission quality in short range. In all, when the VC-234G is in the symmetric mode, it provides a better upstream performance, and when it is in the asymmetric mode, it gives a better downstream performance. It also works in conjunction with vectoring-enabled DSLAMs to remove crosstalk interference and improve maximum line bandwidth across the existing copper 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-demanding Service Connectivity for ISP/Triple Play Devices
The VC-234G provides an excellent bandwidth demand for the triple play devices for home entertainment and communication. With the asymmetric data transmission of 324/60Mbps (G.INP, Asym, 8dB), 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, which is ideal for the following network applications:
- Long-distance IP network devices
- IP digital signage
- Cable TV to IPTV
- Distance video education
- Electronic billboards
- Other applications
Easy and Flexible Installation
The Ethernet-over-VDSL2 Bridge 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 point-to-point connection, a CPE mode VC-234G and a CO mode VC-234G must be set up as one pair of Bridges to perform the connection.
ADSL2+ Fallback
For those ISPs that still provide ADSL broadband service, the VC-234G can support transmission rates up to 24Mbps downstream and 1Mbps upstream with the ADSL2+ technology. The VC-234G establishes a connection with ISP and can be also directly switched over to VDSL2 after the ISP network upgrade.
