VC-204
High Performance Ethernet over VDSL Solution
The PLANET VC-204 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). The VDSL2
technology offers the absolutely fastest data transmission speeds over
existing copper telephone lines without the need of rewiring. The VC-204
supports ultra-high performance to the pervasive telephone line network
with up to 100/55Mbps asymmetric data rate within 200m and 25/4Mbps
for 1.6km long range connections.
Implements with Existing Telephone Copper Wires
The VC-204 is also a Long Reach Ethernet (LRE) converter provides 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-204 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-204 into the existing RJ-11 telephone
jack and a high-performance VDSL2 network can be connected. It is ideal
for use as an Ethernet extender to an existing Ethernet network.
Delivers High-Demand Services Connectivity for ISP / Triple Play
Devices
The VC-204 provides excellent bandwidth to satisfy the triple play devices
for home entertainment and communication. With the capability of
100/55Mbps symmetric data transmission, the VC-204 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 Converter 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. There are two selectable models of the VC-204,
one is used at client side (CPE) and the other one is at central side
(CO). The CPE or CO mode can be adjusted by using a built-in DIP
switch. For point-to-point connection, a CPE mode VC-204 and a CO
mode VC-204 must be setup as one pair of converters to perform the
connection.
Provides Superior Upstream and Downstream Transmission
The VC-204 also defines asymmetric (Plan 998) and symmetric (Plan
997) band plans for the transmission of upstream and downstream
signals. The featured band plan 997 provides the symmetric
transmission on both downstream and upstream. On the other hand,
the band plan 998 performs higher transmission quality in short range
for central side (CO) in asymmetric mode. In all, when the VC-204
is in symmetric mode, it provides better upstream performance, and
when the VC-204 is in asymmetric mode, it gives better downstream
performance.
