VC-234
High Performance Ethernet over VDSL Solution
The PLANET VC-234 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 VC-
234 supports ultra-high performance to the pervasive telephone line
network with up to 100/100Mbps asymmetric data rate within 300m and
20/4Mbps for 1.4km long range connections.
Implements with Existing Telephone Copper Wires
The VC-234 is also a Long Reach Ethernet (LRE) Bridge providing four RJ-
45 Ethernet ports 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 VC-234 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 VC-234 into the existing RJ-11 telephone jack
and a high-performance VDSL2 network can be connected. The VC-234 is
ideal to be used as an Ethernet extender to an existing Ethernet network.
Delivers High-Demand Service Connectivity for ISP / Triple Play Devices
The VC-234 provides excellent bandwidth to satisfy the triple play devices
for home entertainment and communication. With the capability of
100/100Mbps symmetric data transmission, the VC-234 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 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 VC-234 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-
234 and a CO mode VC-234 must be setup as one pair of converters to
perform the connection.
Provides Superior Upstream and Downstream Transmission Performance
The VC-234 also defines symmetric band plan for the transmission
of upstream and downstream signals; the band plan performs higher
transmission quality in short range for central side (CO) in symmetric
mode. In all, when the VC-234 is in profile 17a operation mode, it
provides long distance transmit with Ultra-high performance to the
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.
