www.pulseelectronics.com ex135.a (02/12) z-blocker ? Z-330TJA description the Z-330TJA is a small, ansi t1.421 compli - ant in-line flter designed to expedite the service delivery and improve the performance of digital subscriber line (dsl) and home phone line net - work (hpn) services. this model flters all tele - phone sets, facsimile machines, answering ma - chines, etc. individually or in groups and includes an additional unfltered jack for use with an xdsl modem and/or homepna device. our in-line flter design electronically isolates the high-speed dsl and hpn data streams from the voice band plain old telephone service (pots). this third order flter design effectively blocks the xdsl, hpn and other radio frequencies up to 30 megahertz (mhz). applications the Z-330TJA flter is used with other z-block - er ? flters distributed throughout the subscribers' premises to isolate all voice band equipment de - vices such as corded/cordless telephones, answer - ing machines, fax machines, 56kb/s and lower rate modems, automatic dialers, recorder connec - tors and satellite television set-top boxes. features isolates telephone equipment impedances from the xdsl and hpn systems provides a convenient dsl/hpn jack for easy broadband access attenuates dsl & hpn signals to phone equipment to prevent conversion to voice band signals attenuates hpn signals to unbalanced phone equipment to prevent radiation into electronic equipment attenuats radio signals picked up by an unbalanced telephone acting as an antenna from affecting dsl or hpn receivers minimizes voice band interference --- transmission, signaling and supervision 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 z-blocker ?
