1. Introduction
This document describes the how to use the Korenix JetCon 2502 Ethernet
over VDSL extender, including installation and specifications. Following this
user manual, you will be well learned about how to help you construct
Network infrastructure with JetCon 2502. The followings are brief
introduction of JetCon 2502.
Ideal Ethernet /Voice Extender
JetCon 2502 is an Ethernet/POTS to VDSL2 (Very High-Rate Digital
Subscribe Loop -2) extender and is compliant with ITU-T G.993.2 standard.
It allows the VDSL2 carriers to deliver Ethernet data & voice up to 100Mbps
in both upstream and downstream over existing twisted copper. The JetCon
2502 Ethernet over VDSL converter features Discrete Multi-Tone
modulator/ de-modulator and VDSL Analog Front End (AFE) technology; it
is an ideal solution to carry POTS signal (Voice) and Ethernet Data stream
to 3000 feet to extend local LAN and voices over the same line.
Economical and Simple Connection
To deploy VDSL2 access with the telephone network, the VDSL2 converter
should follow the line impedance of telephone network. Therefore, each
region will adopt different line splitter to provide best communication quality.
Therefore, users need additional wiring and splitter, but mostly make a
jumble at home or office. The JetCon 2502 has implement splitter for each
region to save your installation time.
Central and Discrete Internet Access
For the network infrastructural, JetCon 2502 is the best choice to plan
centralized internet access through the existing POTS wiring system for
hotels, dormitories or where need extend LAN over 100m over a single pair
of copper wires.
Triple Play – HDTV, Data Access, Video conference
JetCon 2502 allows users to compete with wireless and satellite providers
by offering outstanding service, such as Video conference, HDTV or Video
chatting over a existing telephone copper cable without any configuration;
just plug and play to enlarge infrastructure for your applications.

Internet last mile access
The VDSL2 technology also deployed at the last mile of internet access; the
ISP uses the fiber cable as backbone uplink to the basement of building
(FTTB) or corner of streets (FTTC) and uses the exist 1 pair twisted cable of
POTS system to carry voices and Ethernet data stream for user via VDSL2
signal.
Intelligent Traffic System application
In the Intelligent Traffic system (ITS), the VDSL2 technology could be
applied in the long distance data transmission for traffic signal control or
traffic information signboard. JetCon 2502 can save the deployment cost of
fiber by using the twisted cable up to 3000 feet at DS/US data rate 35Mbps /
8Mbps for low speed data transmission over the Ethernet link distance.
Subway & Railway System application
JetCon 2502 can also be applied in the subway and railway system to offer
long distance transmission with low data traffic; for example, the Fire Alarm
System (FAS) and Passenger Information Direction System (PIDS) use the
VDSL2 technology to communicate between outdoor device and Control
Room to replace the fiber cable and save the cost of deployment
