DSL Filters

2Wire 1-Line Inline DSL Filters are for single line telephones or phoneline devices (such as fax machines, answering machines, and analog computer modems). The 1-line inline DSL filter installs easily between the phone jack and telephone device. Once the filter is installed, telephone devices will be completely isolated from the DSL frequency spectrum, resulting in clear phone service.

Eliminate Interference Ensures optimized DSL connections and "total isolation" of analog noise, interference, and modem errors. Compatible Complies with G.lite ADSL, Full-Rate G.dmt, final T1/E1 specification, and HPNA version 1.0 and 2.0 technologies.

Connect Multiple Filters Supports up to five (5) phone filters without any degradation in line quality. Technical Specifications All 2Wire DSL filters ensure optimized DSL connections and "total isolation" of analog noise, interference and modem errors.

• 2Wire DSL filters can be used with telephones, fax machines, and analog modems that share a DSL line or use home computer networks (HPNA), or both.
• Use one filter for each telephone device. If several devices are connected to the same telephone wall jack, use only one filter between the first device and the wall jack.
• Complies with Full Rate G.dmt (G.992.1) and G.lite (G992.2) ADSL.
• Complies with the final T1/E1 specification.
• Stopband rejection greater than 25 dB beyond 50kHz.

  We are a distributor of broadband DSL filters and splitters from the innovators and leaders in broadband technology - Bourns, Pulse/Excelsus, Tii Network Technologies, 2Wire and Wilcom. Separating the DSL signal from the telephone service requires either a splitter in or near the NID or DSL filter at each device. DSL filters (micro-filters) are available for one and two line POTS/telephone installations. For DSL splitters please visit: DSL/ADSL/VDSL splitters

DSL filters - What are they ? Why you may need one (or more) ?

  DSL filters, also known as a micro-filters, is a small in-line device sometimes required in DSL installations. It filters line interference to standard telephone phone equipment when the equipment lines share the same line as the DSL service. DSL stands for Digital Subscriber Line, an always-on Internet service provided through in-place telephone lines. The ISP providing DSL service uses these standard telephone lines to provide a high-bandwidth channel that can deliver downstream speeds up to 3mbps. A special DSL modem is required and DSL filters may also be required, depending on the installation method

   Without DSL filters, signals or echoes from analog/telephone devices at the top of their frequency range can result in reduced performance and connection problems with DSL service. While those from the DSL service at the bottom of its range can result in line noise (poor voice quality, actual audio noise, and functional problems) for analog/telephone devices.

NOTE:
  If DSL filters are used instead of a splitter, a maximum of five phone devices with filters can be used before they begin to excessively degrade the DSL signal.
