Z-BLOCKER® Z-300LS-T
xDSL over POTS In-Line Filter
Description
The Z-300LS-T is a small in-line filter designed to
expedite the service delivery and improve the
performance of digital subscriber line (DSL) and
home phoneline network (HPN) services. This
model fits all telephone sets, facsimile machines,
answering machines, etc. individually or in groups
on line 1 only. Our in-line DSL filter design
electronically isolates the high-speed DSL and
HPN data streams from the voice band plain old
telephone service (POTS) equipment. This design
effectively blocks the DSL, and HPN up to 30
Megahertz. Applications
The Z-300LS-T filters are used with other
Z-BLOCKER® filters distributed throughout the
subscribers' premises to isolate all voice band
equipment devices such as corded/cordless tele-
phones, answering machines, fax machines,
56Kb/s and lower rate modems, automatic dialers,
recorder connectors and satellite television set-top
boxes.
The Z-300LS-T in-line DSL filter is one of many
filters manufactured by Excelsus for subscriber in-
stalled digital services within homes, offices, and
hotels. Excelsus is the number one selling brand of
DSL filters worldwide.
