DSL Filters

Description:
The Z-D250P2J is a small, in-line customer premise equipment (CPE) DSL filters designed to expedite the service delivery and improve the performance of digital subscriber line (DSL) and home phoneline network (HPN) services over plain ordinary telephone service (POTS). The Z-D250P2J filters all telephones, facsimile (fax) machines, answering machines, and other telephone equipment. Its filter design electronically isolates the high-speed DSL and HPN data streams from the voice-band POTS to provide premium voice quality and optimal DSL and HPN data rates. The Z-D250P2J filters both line 1 and line 2 at a two-line jack to reduce crosstalk that can occur between lines.

Features
• Isolate telephone equipment impedances from the xDSL and HPN systems
• Blocks xDSL and HPN signals from voice-band equipment up to 10 Megahertz
• Filters both lines at a two-line jack
• Provides a convenient DSL/HPN jack for easy broadband access
• Compatible with all major xDSL standards including ADSL Full Rate (ITU-T G.992.1), ADSL G.Lite (ITU-T G.992.2), ADSL2 (ITU-T G.992.3 and .4), ADSL2+ (ITU-T G.992.5 in analog mode), ADSL2++, VDSL (ITU-T G.993.1), VDSL2; also V.90 and Metallic Loop Testing compatible
• Compliant and listed with UL / CSA 60950, FCC CFR 47 Part 68, and IC CS-03

Applications:
The DSL user installs the Z-D250P2J in-line DSL filters into each telephone line jack in the subscribers’ premises that contains voice-band equipment devices, including corded/cordless telephones, answering machines, fax machines, 56Kb/s and lower rate modems, automatic dialers, recorder connectors and satellite television set-top boxes.

  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, 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

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.
