Z-330TJA Datasheet, PDF (1/2 Pages) Pulse A Technitrol Company – Isolates telephone equipment impedances from the xDSL and HPN systems

Z-BLOCKER® Z-330TJA
Description
The Z-330TJA is a small, ANSI T1.421 compli-
ant in-line filter 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 filters all tele-
phone sets, facsimile machines, answering ma-
chines, etc. individually or in groups and includes
an additional unfiltered jack for use with an xDSL
modem and/or HomePNA device. Our in-line filter
design electronically isolates the high-speed DSL
and HPN data streams from the voice band plain
old telephone service (POTS). This third order
filter design effectively blocks the xDSL, HPN
and other radio frequencies up to 30 Megahertz
(MHz).
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
