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.
1
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

4-1. Install and Wiring
JetCon 2502 is an Ethernet over VDSL Extender which adopted 2 RJ-11 connectors for the connection of Line and VDSL communication; the Ethernet supports RJ-45 for 10/100Mbps. About the connectors, please refer to figure
2-2-2 in chapter 2.2.
In figure 4-1-1, the architecture uses traditional 1 pair twisted cable between central office (CO site) and remote (CPE site) to achieve data and voice communication over VDSL 2 technology without wire reconstruction.
Figure 4-1-1
11
Connecting the communication port
CO (Central office) site: The RJ-11 port (Line) on the CO site should connect to voice network – (PSTN); JetCon 2502 will modulate voice and Ethernet signal into VDSL-2 signal and forward to CPE site by paired twisted cable through RJ-11
(VDSL-2 ) connector. During the communication, the LED will activate as different operating status. Please refer to chapter 2-2 for LED description.
CPE (Customer premise equipment) site: the remote CPE site is the same as CO site; the line port is connected to a POTS Phone and provides voice communication.
4-2. Dip switch configuration
JetCon 2502 provides 4 DIP switches for system configuration; each DIP switch has independent function. Please refer to the following description.
DIP Switch -1: Mode selection.
Master mode (On): Acts as Central office (master).
Slave mode (Off): Acts as remote office (slave).
Each JetCon 2502’s mode should correspond to central (master) or remote (slave) installation. The default setting is slave mode (off)
DIP Switch-2: Impulse Protection.
The impulse protection can deliver better communication quality under 250ms duration of noise when configuring this function; the stream will have longer forwarding latency.
On: Interleave mode with six ms forwarding latency time.
Off: Fast mode with one ms forwarding latency time.
DIP Switch-3: Symmetric.
Symmetric mode (Off): Upstream and downstream with same data forwarding rate.
The default setting is “Off”.
Asymmetric mode (On): Upstream and downstream with different data forwarding rate.
DIP Switch-4: SNR (Signal to Noise Ratio)
SNR (On): Better channel noise protection with SNR up to 9 dB.
SNR (Off): Original channel noise protection with 6 dB SNR. (Default setting)
Activate these functions when JetCon 2502 is allocated or installed in environments with huge electric static or electric magnetic interferences.

4-3. VDSL2 Technology
The VDSL (Very High Bit-rate Digital Subscriber Line) is a DSL technology providing faster data transmission over a single flat untwisted or twisted pair of copper wires. These fast speeds mean that VDSL is capable of supporting high bandwidth applications such as HDTV, as well as telephone services (Voice over
IP) and general Internet access, over a single connection. VDSL is deployed over existing wiring used for POTS (Plain Old Telephone Service) and lower-speed
DSL connections. This VDSL standard ITU G.993.1 was approved and released in
November 2001.
The VDSL2 is second generation of VDSL and standardized as ITU-T G.993.2 in
Feb, 2006. It is an access technology that exploits the existing infrastructure of copper wiring network originally deployed for POTS services. It can be deployed from central offices, from fiber-end cabinets that located near the customer premises, or within buildings for the last mile access of FTTB (Fiber to the building), FTTH (Fiber to the home) or FTTC (Fiber to the corner, cabinet).
The VDSL 2 technology is the newest and advanced technology that deploys on the copper wires to support triple play services, such as voice, data, high definition television (HDTV) and interactive games.
The VDSL 2 has defined 3 band planes- Annex A for North-American, Annex B for
Europe and Annex C for Japan. Band plan is defined as the following frequency spectrum diagram.
Annex A, North American
Annex B, Europe, 997 symmetric band plan

11. Repeat step 10 to make sure the Ethernet connection of both sites is successfully established.
12. Pick up the remote-site POTS phone and check the dial tone is heard from the phone receiver to ensure the Public Switched Telephone Networks has recognized that a phone has gone off-hook; and the switching equipment is prepared to receive the dialed digital tone or DTMF code.
21
13. Try to dial a phone number to establish a voice connection to make sure the voices are clear.
14. If the data or voice communication cannot establish, please contact Korenix local dealer or distributor for further assistance.
5-2. Troubles shooting
Make sure you use the correct DC power suppliers (DC12~ 48 V) or power adapters.
Select Ethernet cables with specifications suitable for your applications to set up your systems. Ethernet cables are categorized into unshielded twisted-pair
(UTP) and shielded twisted-pair (STP) cables. Category 3 Ethernet cables are suitable for systems with 10 Mbps transmission speed. For systems with
100Mbps transmission speed, Category 4, 5 Ethernet cables are the only suitable specifications for this environment. Also make sure that the distance between each node cannot be longer than 100 meters (328 feet).
If the power LEDs goes off as the power cord plugged in, a power failure might occur. Check the power output connection to see if there is any error at the power source. If you still cannot solve the problem, contact your local dealer for assistance
