Description:
The  Z-330CWA is a  small, ANSI T1.421 compliant, wall mount filter designed to expedite the service delivery and improve the performance of Asymmetric  Digital  Subscriber  Line  (ADSL) and Home Phoneline Network (HPN) services.  This  model  filters  all  telephone  sets,  facsimile machines, answering machines, etc. individually or in groups and includes an additional unfiltered  jack  for  use  with  an  ADSL  modem and/or  HomePNA  device.  The DSL filter design electronically isolates the high-speed DSL and HPN data streams from the voice band Plain Ordinary Telephone Service (POTS). This third  order  filter  design  effectively  blocks  the ADSL, HPN and other radio frequencies up to 10 Megahertz (MHz). 
Applications:
The  Z-330 CWA filter is used with other filters  distributed throughout  the subscribers' premises to isolate all voice band equipment devices such as telephone sets (including cordless types), answering machines, facsimile (fax) machines, 56Kb/s and lower rate modems, automatic dialers, and recorder connectors.  The filters may also be  used to isolate the telephone network jack connected  to  a  digital  cable  and/or  satellite television set-top box.
