Inlet splitting plane, high pass filter splitting plane, and main distribution frame
First Claim
1. An inlet splitting plane for a main distribution frame, comprising:
- a low pass filter which permits a telephone communication signal to pass therethrough and does not permit an ADSL (asymmetric digital subscriber line) signal to pass therethrough.

Abstract
A main distribution frame (MDF) is provided for providing the user with ADSL services by simply making a slight modification to a conventional main distribution frame and performing an extremely simple wiring operation. An inlet splitting plane (ISP) and a high pass filter splitting plane are also provided which can be suitably used in the main distribution frame. The main distribution frame has an outlet splitting plane, the inlet splitting plane having a low pass filter, and a high pass filter splitting plane having a high pass filter. The outlet splitting plane is connected to supply its output to the inlet splitting plane and high pass filter splitting plane in parallel. The inlet splitting plane is connected to a telephone exchanger system, while the high pass filter splitting plane is connected to an ADSL system.
