Description

Communication network, distribution frame, communication method, and patch panel mounting method

The present invention relates to the field of communications, and more particularly to a communication network, a distribution frame, a communication method, and a wiring rack mounting method. Background technique

In the field of telecommunications, operators can provide broadband telecommunication services or narrowband telecommunication services to users through a pair of twisted pairs. They can also provide broadband telecommunication services and narrowband telecommunication services to users at the same time, such as: 1) ordinary telephones are opened asymmetrically Digital subscriber line (Asymmetrical Digital

Subscriber Loop over Plain Old Telephone Service, ADSL over POTS);

2) ADSL over Integrated Services Digital Network (ADSL over ISDN) is added to the integrated services digital network;

3) Very high speed DSL; Very High Rate DSL over POTS (VDSL over POTS);

4) ISDN will open VDSL (VDSL over ISDN) and other services.

At present, these businesses have been carried out quite widely at home and abroad. In this paper, broadband services based on twisted pair for ADSL, VDSL, etc. are collectively referred to as xDSL.

The above various services use the network equipment consisting of the central office equipment, the distribution frame, and the customer equipment shown in FIG. At the central office, it includes a Digital Subscriber Line Access Mulitiplexer (DSLAM, also known as a broadband access device) and POTS/ISDN. The DSLAM includes an xDSL service board and a splitter (SPL), and the POTS/ISDN includes a POTS/ISDN service board. On the user side, including SPL, telephone, and Remote Terminal Unit (RTU). The MDF is connected to multiple client devices, and each user terminal is connected to an external MDF. The MDF connects the client devices to the central office device through the user's external line.

When processing the service, the xDSL signal and the POTS/ISDN signal coexist in one user's outside line. In the bureau On the end side, the SPL in the DSLAM separates the wide and narrow services and sends them to the broadband service board (xDSL service board) and the narrowband service board (POTS/I SDN service board) for processing. On the user side, the SPL will The separated wide and narrowband services are sent to the RTU and the telephone of the client respectively.

In practice, when a narrowband user applies for broadband services, the central office must add the SPL in the DSLAM to separate the wide and narrowband service data. In addition, in order to ensure the normal operation of the xDSL service, it is necessary to diagnose various types of faults that affect the service in a timely manner. Therefore, it is necessary to measure the subscriber line parameters, and the broadband test unit (BTU) that performs the measurement needs to access the above services. Going in the network, and such access does not affect the normal development of the business.

Referring to Figures 2 and 3, another prior art broadband telecommunications service network employs an MDF-based splitter mounting structure. In this scheme, the SPL is installed on the MDF, and each SPL corresponds to one user. The SPL is inserted into each wiring terminal on the MDF frame by a structure such as a gold finger (shown in Figure 3). Each user corresponds to 8 wiring terminals, wherein the upper two terminals are connected to the DSLAM, the upper right two terminals are connected to the POTS/I SDN (ie, the switch), and the lower right two terminals are connected to the subscriber line, the lower left The two terminals of the square are not used. The input gold finger in the SPL is connected to the subscriber line terminal of the wiring terminal, and the output gold finger is connected to the DSLAM and POTS/I SDN terminals. The network has the following characteristics:

1) The wideband and narrowband client device is connected to the MDF, and the voice telephone signal is separated to the switch user terminal through the SPL, and the wideband digital signal is directly connected to the DSLAM user terminal;

2) For users who have not opened broadband services, the SPL module is not installed at the MDF, and the physical path of the subscriber line through the MDF to the DSLAM is interrupted, and only the voice signal of the telephone is reserved to the switch.

(The MDF wiring terminal connects the subscriber line and the switch by default);

3) It is no longer necessary to install SPL in the DSLAM machine.

In carrying out the creation process of the present invention, the inventors found that at least the following problems exist in the existing broadband service network technologies:

Since one SPL corresponds to one user, the MDF is generally installed near the user. In practice, each user needs to delegate the staff to the MDF site to perform the operation of plugging the SPL into the corresponding user wiring terminal when applying for broadband service. Obviously, the time for applying for broadband service is not uniform but the number is small. When a large new application is applied, the labor cost is high; and, whether it is an operator or a newly applied user, it takes a lot of time to install the broadband. Similarly, when broadband users need to revoke broadband services, they still need to delegate staff to the MDF site, spending the same labor and time costs. Summary of the invention

As can be seen from the above embodiment, since the connection module 422 including the plurality of separation units 4221 is used on the distribution frame connecting the client device 410 and the central office device 430, the existing one separate separator corresponds to one user terminal. The design of the device installation is changed to integrate a plurality of separation units 4221 on one module, and each separation unit 4221 corresponds to one client device 410. Thus, a connection module 422 can be used to plug in the wiring terminals of the plurality of client devices 410.
