Z-BLOCKER® Z-D250CWA Dual-Line Wall-Mount Filter Description The Z-D250CWA is a compact, dual-line, wallmount customer premises equipment (CPE) filter designed to expedite the service delivery and improve the performance of digital subscriber line (DSL) and home phoneline network (HPN) services over plain old telephone service (POTS). The Z-D250CWA 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-D250CWA filters both line 1 and line 2 at a two-line wall jack to reduce crosstalk and interference that can occur between lines. The filter also provides a convenience jack for DSL or HPN connections. The wall-mount filter allows two-line filtering of both the wall phone and a second phone device, such as an answering or fax machine. Features Front and back views of the Z-D250CWA. Note that in-line filter can be removed from wall-mount housing, giving subscribers without wall-mount phones an additional in-line filter. Applications Installation of the Z-D250CWA wall-mount filter is quick and easy. The DSL user simply removes and disconnects the wall phone, connects and aligns the Z-D250CWA filter with the mounting screws of the wall plate, pushes the locking tabs in place, and reconnects and attaches the wall phone. ● Filters both lines at a two-line wall jack ● Provides filtered connections for up to two phone devices ● Isolate telephone equipment impedances from the xDSL and HPN systems ● Blocks xDSL and HPN signals from voice-band equipment ● Provides a DSL convenience jack for connecting a DSL modem or HPN device ● Compatible with all major xDSL standards including ADSL Full Rate (ITU-T G.992.1), ADSL G.Lite (ITU-T G.992.2), ADSL2 (ITUT G.992.3 and .4), ADSL2+ (ITU-T G.992.5 in analog mode), ADSL2++, VDSL (ITU-TG.993.1), VDSL2; also V.90 and Metallic Loop Testing compatible The DSL user installs an Excelsus filter into each telephone line jack in the subscriber’s 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.
