upstream, high Performance Ethernet over VDSL
Solution 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 symmetric data rate within 300m and
20/4Mbps for 1.4km long range connections.
    Implementing 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.
  Delivering 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 the local Internet,
such as VOD (Video on Demand), Voice over IP, Video phone,
IPTV, Internet caching server, distance education,
and so on.   Easy & 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-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.
  Providing 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.
