Z-BLOCKER® Z-330PJ
xDSL over POTS CPE In-Line Filter
Description
The Z-330PJ is a small, in-line, ANSI T1.421-com-
pliant customer premises equipment (CPE) filter de-
signed 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-330PJ filters
all telephones, facsimile (fax) machines, answer-
ing machines, and other telephone equipment. Its
third-order 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.
Z-330PJ xDSL over POTS CPE In-Line Filter
