ABSTRACT:
A modular jack includes a filter circuit for each of the transmit and receive pins in order to shape the signal waveforms, isolate the user from the line, and filter out both common and differential mode noise in high-speed communications systems, such as 10BASE-T, 100BASE-T, token ring and ATM applications. The manufacture of the modular jack of the present invention is simplified by the design of the components which make up the modular jack assembly. More specifically, the contact pins of the modular jack are divided into a contact pin array and a mounting pin array. The two pin arrays are electrically coupled through a printed circuit board which carries the two filters. A platform formed on the mounting pin array facilitates the attachment of the printed circuit board during manufacture.
