Main distribution frame and method for implementing same

Abstract

The embodiment of the invention relates to a main distribution frame and a method for implementing the same. The method for implementing the main distribution frame comprises the following steps: separating a composite signal transmitted by a user into a narrow-band signal and a broadband signal; and respectively carrying out circuit switching on the separated narrow-band signal and the broadband signal by adopting a narrow-band switching matrix module and a broadband switching matrix module. In the method, by separating the composite signal on a subscriber line into the narrow-band signal and the broadband signal, circuit switching is respectively performed on the narrow-band signal and the broadband signal by adopting the narrow-band switching matrix module and the broadband switching matrix module so as to provide different switching implementation modes by aiming at the different signals.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for realizing a general distribution frame and the general distribution frame. Background technique [0002] Main Distribution Frame (MDF) is a connection and protection module in wired communication technology, which is used to connect central office equipment and user terminals, and provide overcurrent and / or overvoltage protection for lines. [0003] The main distribution frame usually includes a switching matrix module (CROSS-CONNECT MATRIX, CCM) and a protection module. For applications that provide narrowband services and broadband services at the same time, the user line can contain narrowband and broadband service signals, narrowband services such as POTS (Plain Old Telephone Service, ordinary telephone service), broadband services such as XDSL (X Digital Subscriber Line, digital subscriber line business). Specifically, the subscriber line (Subscriber Lin...

Problems solved by technology

[0005] Since the existing switch matrix module directly selects the path of the subscriber lines containing narrowband and broadband service signals, and the narrowband and broadband service signals have different characteristics, then the switching implementation of the switch matrix module cannot adapt to the characteristics of narrowband and broadband signals at the same time , and, once the switching matrix module fails, all services of the subscriber line will be affected
