Method for setting wire distributing frame, wire distributing frame and wire distributing frame module

Abstract

This invention relates to a method for designing a wiring frame which is to set IMB on a wiring frame including a filter circuit separating broadband signals and narrow band signals or wire protection circuit of narrowband port or that of broadband service port, or those of narrow and broadband service ports, or protection circuit of narrowband service port and a filter separating broadband and narrowband signals or circuit of the broadband and filter separating broadband and narrow band signals, or the circuit of narrow band, the said circuit of broadband and filter separating signals of broadband and narrowband.

Description

technical field [0001] The invention relates to a distribution frame, a distribution frame module and a setting method in a distribution system in the wired communication field of telecommunication services. Background technique [0002] In the wiring system in the wired communication field of the telecommunications business, the internal line module of the distribution frame MDF (Main Distribution Frame) only provides the function of line connection. Therefore, for applications that provide broadband telecommunication services and narrowband telecommunication services on a pair of user lines at the same time, such as ADSL overPOTS (additional ADSL for ordinary telephones), ADSL over ISDN (additional ADSL for ISDN), VDSL over POTS (additional ADSL for ordinary telephones VDSL), VDSL over ISDN (ISDN plus VDSL) and other applications, it is necessary to equip the broadband access equipment (DSLAM, DSL Access Manager) with a circuit component that separates the broadband and na...

Problems solved by technology

[0007] from figure 2 image 3 It can be seen that the disadvantages of the prior art are: (1) if the broadband service is added on the basis of the narrowband service, it is necessary to add 2 (or 2 groups) internal line modules of the distribution frame in the MDF for each user, and the cost and The space requirement is relatively high; (2) There are 2 sets of cables between the MDF and the DSLAM, one set carries (xDSL+POTS / ISDN) line signals, and the other set carries (POTS / ISDN) line signals; (3) Because the splitter circuit is inside the DSLAM equipment, it will occupy the space of the DSLAM equipment rack, resulting in a decline in the number of broadband users that can be accommodated by a DSLAM equipment rack, which limits the increase in the port density of the DSLAM; (4) The jumper operation to be done on the MDF is more complicated

(5) Both broadband and narrowband line cards have protection circuits, and the protection circuits are repeated, resulting in an increase in system cost
