  • Page 3: Foreword: Vdsl2 Solution

    Since VDSL2 has the characteristic of higher bandwidth over shorter distances, the ideal architecture for Telecoms is to use fiber optic lines as the backbone and a VDSL2 line as the last mile into the home or office. With outstanding throughput, the NV-202 can complement a fiber network to offer the best solution for delivering Triple play(Video/Voice/Data) or home entertainment services.

  • Page 20 NV-202 VDSL2 Bridge with DIP Switch USER’S MANUAL Ver. A4 TIP(Reference Only): Interleave delay function is used in digital data transmission technology to protect the transmission against noise issue and data error. If during transit more than a certain amount of data has been lost then the data cannot be correctly decoded. Short bursts of noise on the line can cause these data packets to become corrupt and the bridge has to re-request data which in turn can slow down the overall rate at which data is transmitted.
  • Page 21 2. Please note that the user can use 12VDC power input. Do not exceed DC 12V. Be sure to disconnect the power before installing and/or wiring your NV-202 bridge. Please calculate the maximum possible current in each power wire and common wire. Observe all electrical codes dictating the maximum current allowable for each wire size.
