Planet Technology Network Router VC 204 User Manual

VC-204  
4-Port Ethernet over VDSL2 Bridge  
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.  
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.  
Key Features  
Cost-effective VDSL2 CO / CPE bridge solution  
Implements with Existing Telephone Copper Wires  
One box design, CO / CPE selectable via DIP Switch  
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.  
Defines asymmetric (Plan 998) and symmetric (Plan 997) band  
plans for the transmission of upstream and downstream signals  
Complies with IEEE 802.3, IEEE 802.3u and IEEE 802.3x  
standards  
DMT (Discrete Multi-Tone) line coding  
Half duplex Back pressure and IEEE 802.3x Full Duplex Pause  
frame flow control  
Built-in POTS splitter to share voice and data  
Delivers High-Demand Services Connectivity for ISP / Triple Play  
Devices  
Two RJ-11 connectors for each VDSL port, one for VDSL  
connection and one for POTS connection  
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.  
Voice and data communication can be shared simultaneously  
based on the existing telephone wire  
Supports up to 1536 bytes packet size, IEEE 802.1Q VLAN tag  
transparent  
VDSL2 stand-alone transceiver for simple bridge modem  
application  
Advantage of minimum installation time (Simply as Plug-and-  
Play)  
Easy Installation  
Selectable target band plan and target SNR margin  
The Converter is plug-and-play design and fully compatible with all kinds  
of network protocols. Moreover, the operating status of each individual  
Supports extensive LED indicators for network diagnostics
