Problems solved by technology

[0003] The technical background of network cable power supply and public switch telephone network PSTN voice: this technology has been developed on the basis of network cable power supply, which increases the transmission capacity of PSTN voice. At present, the demand for information technology of network terminal equipment is strong, and data is transmitted purely through data network Although the IP phone with voice can meet this demand, it needs the cooperation of gateways in various places, and it has not been used on a large scale at present.

Embodiment Construction

[0013] A kind of data interface, described interface comprises Ethernet interface line RJ45 network cable and transformer coupler, 4 pairs of twisted pairs in the RJ45 network cable namely 8 lines are determined as (1, 2, 3, 4, 5, 6 in order) , 7, 8), where 1, 2, 3, and 6 wires are defined as data / telephone wires, 4, 5 wires are defined as power supply positive wires, and 7, 8 wires are defined as power supply negative wires, as shown in the table 1; RJ45 has a total of 8 wires, and the connecting cable contains 4 pairs of twisted pairs. The Institute of Electrical and Electronics Engineers IEEE802.3 standard defines two pairs of twisted pairs 1, 2, 3, and 6 for data transmission, and the other two pairs of twisted pairs Not useful or reserved. Based on the definition of IEEE802.3, IEEE802.3af utilizes the remaining two pairs of cables or data lines as power feed. In addition to power feeding and data transmission, we also need to transmit telephones, and we must ensure compa...

Abstract

This invention relates to a data interface especially to a data interface deciding power supply and phone relying on the type of data terminal equipments(DTE) including the ether net interface line RJ45 net line and a transformation coupler, four pairs of twisted-pair lines in RJ45 net line are defined as follows: 1, 2, 3, 6 are defined as the data/phone lines, 4,5 are defined as the power positive terminal lines, 7,8 are the negative lines, and 1,2 are connected with either end of the coupler, the central tap of the coupler is linked to the phone line, 3,6 are connected with either end of another transformation coupler, the central tap is linked with the phone line, those who use said interface can switch in the ether net to realize data communication or switch in PSTN net to transfer phones and provide feed for terminal equipments. This invention provides a method for automatically identifying the end type to provide supply to it accordingly.

Description

technical field [0001] The invention relates to a data interface, in particular to a data interface which depends on the type of data terminal equipment (DTE) to determine power supply and telephone. With this interface, it is possible to simultaneously complete access to Ethernet to realize data communication, access to PSTN network to transmit voice and Provides power to end devices. Background technique [0002] Technical background of network cable power supply: accessing through ordinary user lines, not only can access Ethernet to receive / send network data, but also provide remote power supply when power supply is needed. With the development of communication technology, IP phones, wireless LAN access points, and IP security cameras are more popular, and the power consumption of these devices is reduced, so it is very urgent to provide remote power supply through Ethernet network cables. One of the commonly used network terminals (wireless local network access devices,...
