Product Details

High Specification

This is a small in-line filter designed to expedite the service delivery and improve the performance of asymmetric digital subscriber line (adsl) services. This model filters all telephone sets, facsimile machines, answering machines, etc individually or in groups on line. The in-line dsl filter design electronically isolates the high-speed dsl and hpn data streams from the voice band telephone service (pots) effectively blocking the adsl, and other radio frequencies up to 10 megahertz. The advantage of this model is that when the telephone set is on-hook the filter exhibits lower capacitance, which provides improved side-tone and return loss characteristics. This dynamic feature allows several filters to be used on a single phone line without any discernable loss in voice quality.
