Z-BLOCKER® Z-D250P2J
xDSL/POTS CPE Dual In-Line Filter
Description
The Z-D250P2J is a small, in-line 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 ordinary telephone service (POTS).
The Z-D250P2J filters all telephones, facsimile
(fax) machines, answering machines, and other
telephone equipment. Its filter design electroni-
cally 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.
