This technology offers the absolute fastest possible data transmission speeds over existing copper telephone lines or coaxial cables without the need for rewiring. The VC-201A / VC-202A / VC-204 Ethernet Over VDSL2 Converter has a switching architecture with RJ-45 10/100Mbps Ethernet port and one asymmetric or symmetric Ethernet over VDSL port (Asymmetric means upstream and downstream rate are not the same and Symmetric means upstream and downstream rate are similar) – the VDSL port can be RJ-11 connector (VC-201A / VC-204) or BNC Connector (VC-202A). The VC-201A / VC-202A / VC-204 can be set to Central Office (CO) or Customer Premises Equipment (CPE) mode via a DIP switch. When VC-20X-CO (VC-201A / VC-204) is connected with other VC-20X-CPE (VC-201A / VC-204) device, the performance will up to 100/55Mbps for asymmetric data rate within 200m and up to 25/4Mbps for asymmetric data rate at 1.6km. The VC-202A (BNC) performance is up to 100/65Mbps for asymmetric data rate within 200m and up to 25/5Mbps Mbps for asymmetric data rate at 3.0km. This capability is ideal for use as an Ethernet extender for your existing Ethernet network. PLANET VDSL2 Converter provides a much cheaper replacement and smooth migration for existing Long Reach Ethernet (LRE) networks. The cable specifications of the connection are listed as following: l 10Base-T, Category 3, 4 or 5 UTP l 100Base-TX, Category 5, 5e or 6 UTP l Ethernet over VDSL2, Twisted-pair telephone wires l Ethernet over VDSL2, Coaxial cable The two drawings pictures are typical application for the Ethernet over VDSL2 Converter. Note Slave device (CPE) must connect to Master device (CO) through the telephone wire or coaxial cable. It is not allow connecting like Master to Master or Slave to Slave. To define the VC-201A / VC-202A / VC-204 to CO or CPE, please refer to section 2.2.1 for more detail.

By switching the transmission modes, you can obtain a best transmission mode to suit with phone line quality or distance of connectivity. The following is the summary table of transmission setting, bandwidth and distance extensibility tested for AWG 24 (0.5mm) twisted-pair without noise and cross talk. 19 DIP-1 DIP-2 DIP-3 DIP-4 Mode Channel Band Plan SNR OFF CO Interleave Symm 9dB ON (default) CPE Fast Asymm 6dB n CO / CPE • CO (Central Office) – the Master device mode, usually the CO device will be located at the data center of ISP or enterprise to link to the backbone. • CPE (Customer Premises Equipment) – the Slave device mode, usually the CPE device will be located at branch office, home or remote side as the long reach data receiver. The CPE can be connected to the PC, IP Camera or Wireless Access Point and etc network devices. Note When the Ethernet Over VDSL2 Converter operate at CPE mode, the DIP switch 2,3,4 is no function. n Fast and Interleave mode • Fast mode guarantees a minimum end to end latency less than 1 ms. • Interleaved mode provides impulse noises protection with a duration less than 250 us. Interleaved mode has a maximum end to end latency of 10m sec. n Band Plan • User can switch the Band Plan either Symmetric or Asymmetric by their own. When Symmetric is selected that provides better upstream performance, when Asymmetric is selected that provides better downstream performance. Refer to table above for details. 20 n Target SNR (Signal Noise Ratio) Margin • When fixed SNR margin is selected, the system will maintain the SNR margin at 9 dB across all usable loop length. Note By default setting, the four DIP switch at “ON” position and operate as “CPE”. For operate as “CO”, please adjust the DIP 1 switch to “OFF” position. Adjust other DIP switch setting to fill different network application demand. Please power off the Ethernet over VDSL2 Converter before making any transmission mode adjustment. 2.2.2 DC Power Jack VC-201A / VC-202A / VC-204 require 5V DC power input. It will conform to the bundled AC adapter. If you have the issue to make the power connection, please contact your local sales representative. Note 1. The device is a power-required device, it means, it will not work till it is powered. If your networks should active all the time, please consider using UPS (Uninterrupted Power Supply) for your device. It will prevent you from network data loss or network downtime. 2. In some area, installing a surge suppression device may also help to protect your Ethernet Over VDSL2 Converter from being damaged by unregulated surge or current to the Ethernet over VDSL2 Converter or the power adapter. 21 3. Installation 3.1 Install Ethernet over VDSL2 Converter The Ethernet over VDSL2 Converter does not require any software configuration. Users can immediately use any feature of this product simply by attached the cables and plug power on. There is some key limitation on the Ethernet over VDSL2 Converter. Please check the following items: l VC-201A and VC-204: The device is used for Point-to-Point connection only (Master device to Slave device) and has equipped with 2 RJ-11 connectors for VDSL port. One for voice device connection (like telephone) and the other one for network link connection. Depending on the quality of telephone line, the maximum distance of one VDSL segment is 1.6km (5250ft) with AWG 24 telephone wires. l VC-202A: 1 BNC connector and supports 50 or 75 ohm cable. Depending on the quality of coaxial cable, the maximum distance of one VDSL segment is 3.0km (9842ft) with 5C coaxial cable. The distance will change by the quality of telephone wires and coaxial cables. 22 3.1.1 VC-201A / VC-202A / VC-204 LAN to LAN connection Two sets of the Ethernet over VDSL2 Converters could be used to link two local Area networks that are located in different place. Through the normal telephone line, it could setup a 100/55Mbps asymmetric backbone, but one Ethernet over VDSL2 Converter must be Master (CO mode) and the other one is Slave (CPE mode).

FAQ Q1: What voltage that VC-201A / VC-202A / VC-204 used? A1: 5V DC, 2A Q2: What is VDSL2? A2: VDSL2 (Very High-Bit-Rate Digital Subscriber Line 2), G.993.2 is the newest and most advanced standard of xDSL broadband wire line communications. Designed to support the wide deployment of Triple Play services such as voice, data, high definition television (HDTV) and interactive gaming, VDSL2 enable operators and carrier to gradually, flexibly, and cost efficiently upgrade exiting xDSL-infrastructure. Q3: What is the best distance for VC-201A / VC-202A / VC204? A3: In order to guarantee the stability and better quality of network, so we would suggest the distance within 1.6 kilometer is the best for VC-201A / VC-204 and 3.0kilometer for VC-202A. Q4: What is the best date rate for VC-201A / VC-202A / VC204? A4: We provide the data rate of the VC-201A / VC-204 is up to 100Mbps/55Mbps and the VC-202A is up to 100Mbps/ 65Mbps (downstream / upstream) in 200 meters Q5: Can VC-201 compatible with VC-201A / VC-204? A5: Currently NO. Although VC-201 (profile 12a) and VC-201A / VC-204 (profile 17a) are base on ITU-T G.993.2 VDSL2, but with different Profiles, so far they are not compatible with each other. 32 Q6: Can VC-202 compatible with VC-202A? A6: Currently NO. Although VC-202 (profile 12a) and VC-202A (profile 17a) is base on ITU-T G.993.2 VDSL2, but with different Profiles, so far they are not compatible with each other. Q7: What is SNR and what’s the effect? A7: In analog and digital communications, Signal-to-Noise Ratio, often written SNR, is a measure of signal strength relative to background noise. The ratio is usually measured in decibels (dB). In digital communications, the SNR will probably cause a reduction in data speed because of frequent errors that require the source (transmitting) computer or terminal to resend some packets of data. SNR measures the quality of a transmission channel over a network channel. The greater the ratio, the easier it is to identify and subsequently isolate and eliminate the source of noise. Generally speaking, the higher SNR value gets better line quality, but lower performance. Q8: What is band plan and what’s the effect? A8: VDSL2 defines multiple band plans and configuration modes (profiles) to allow asymmetric and symmetric services in the same binder (by designated frequency bands) for the transmission of upstream and downstream signals. User has the ability to select fixed band plan. When Symmetric is selected that provides better downstream performance, when Asymmetric is selected that provides better upstream performance. 33 This page is intentionally left blank This page is intentionally left blank This page is intentionally left blank
