product s pecification CPF101NW data sheet subject to change without notice rdps-pots321(r1)03/15/2002 sheet 3 of 13 1. introduction: the CPF101NW is a splitter module that has been specifically designed to implement the functionality of low pass filter in isdn over adsl application.the CPF101NW integrate low pass filter that block the high frequency energy from reaching the isdn device and provide isolation from impedance effects of the isdn device on adsl. because the isdn splitter connects directly to the subscriber loop media , it must also provide some protection for externally induced line hits or faults which could damage any attached equipment or endanger humans interacting with the installed equipment. the circuit protection will be provided mostly by standard central office line protection means and additional protection measures built into splitter to protect against line overstress which could damage the splitter itself.this splitter mainly consist of one low pass filter which provide isdn and pots solution respectively 2. reference: ref. 1 : etsi tr 101 728 v1.1.1(2000-12) ref. 2 : splitter requirement specification for hm130 ref. 3 : itu-t g.992.1 asymmetrical digital subscriber line (adsl) transceiver ref. 4 : itu-t k.21 resistibility of subscribers terminal to over-voltages and over-currents. ref. 5 : itu-t k.44 resistibility tests for telecommunication equipment exposed to overvoltages and overcurrents ?e basic recommendation 3. abbreviations: adsl asymmetric digital subscriber line isdn integrated service digital network co central office cpe customer premise equipment. pots plain old telephone service rt remote terminal z adsl network termination of adsl
