Problems solved by technology

[0008] However, in these two existing implementation methods, whether it is a dial switch or a jumper cap, manual configuration is required when the external physical interface is changed, which is easy to cause misdialing and missed dialing; in addition, for dialing In terms of switch mode, due to the structural characteristics of the DIP switch itself, it is very likely that the DIP switch will not be in place and cause poor contact.
When users need to dial codes or jump wires, they first need to power off, pull out the entire board, and then set it manually, which means that the business of the entire board will be interrupted

Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0029] In order to solve the problems in the prior art, the embodiment of the present invention provides a copper cable. The main solution is to make the negative signal line in each differential pair in one direction be connected to the ground in the unbalanced 75 ohm copper cable. line connected. Wherein, the negative signal line in each differential pair in one direction can be the negative signal line in the sending differential pair, generally T-signal line; or it can also be the negative signal line in the receiving differential pair, generally R-signal line. In this way, the connection between the negative signal wire and the ground wire in the differential pair is directly realized inside the copper cable, so tha...

Abstract

The invention discloses a coaxial cable, a connector and a system and a method for realizing single-board compatible external connection. Each differential and centered negative signal wire in one direction in the coaxial cable and the connector is connected with a ground wire. In the invention, a breakthrough in the conventional thinking formulary of realizing switchover among interfaces in the single board is made, and the compatibility of the same single board with different physical interfaces is realized creatively by reforming the unbalanced 75-ohm coaxial cable without arranging interface type switching devices such as dial switches, jumper caps and the like in the single board. When the physical interfaces are needed to be switched, the cable is only needed to be replaced without performing operation such as dialing or jumper and the like in the single boards such as a circuit switch interface board and the like, so that the reliability and operability in the process of interface switchover are improved greatly. The coaxial cable, the connector and the system and the method have the advantages of low cost, low failure rates and the like.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a system and method for implementing a copper axis cable, a connector, and a single-board compatible external connection. Background technique [0002] With the development of digital communication technology, communication systems using Plesiochronous digital hierarchy (PDH, Plesiochronous digital hierarchy) have been widely used in various backbone networks and local area networks. However, the prior art PDH only has regional (such as North America, Japan, Europe) digital signal rate and frame structure standards, and there is no unified international standard and interface specification, which has caused great trouble to the use and maintenance of the system. [0003] At present, there are mainly two systems in the PDH series, E1 and T1. Among them, E1 is a subgroup rate, which is a European standard, and the transmission rate is 2048kbit / s; T1 is formulated by the Ameri...
