LEA Customer Premise Solution LEA has developed a full range of solutions for ADSL filtering and is recognized by all the major telecom equipment suppliers and carriers worldwide
Distributed Filter PMF270P01-FR-D The PMF270P01-FR-D is a distributed filter which has been designed to implement the functionality of low pass filter in an ADSL over POTS application. Asymmetric Digital Subscriber Line (ADSL) is a technology used to transmit broadband information over existing copper wires that connect home and businesses to the Public Switched Telephone Network (PSTN). ADSL is very viable technology to support high-speed access, enabling a theoretical maximum downstream rate of 9Mbps and a maximum upstream rate of 640kbps. POTS service can coexist with ADSL without interruption or degradation of service due to the filtering action of the ADSL/POTS splitter. The PMF270P01-FR-D is functionally a low pass filter which separates the transmission of POTS signals and ADSL band signals. A second purpose is to isolate poorly balanced POTS equipment from the line at ADSL band frequencies in order to prevent unnecessary egress (and ingress) from ADSL signals. As the POTS splitter connects directly to the Subscriber Line media, it must also provide some protection for externally induced line hits or faults which could damage any attached equipment or endanger
