Product Specification

CPF127F

1. Introduction:

The CPF127F is a splitter module that has been specifically designed to implement the

functionality of low pass filter in ISDN over ADSL application.The CPF127F integrate low

pass filter that blocks 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 consists of one low pass filter which provides ISDN and POTS

solution respectively
