Introduction:
The CPF102IG is a splitter module that has been specifically designed to implement the functionality of low pass filter in ISDN with 2B1Q/4B3T over ADSL application. The CPF102IG 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.
