Embodiment Construction

[0022] FIG. 1 shows two shunt elements T1 , T2 , as shown respectively in FIG. 4 in the above-cited WO 2005 / 053221 .

[0023] Between the two shunt elements T1 and T2 there is a coupling in the form of an electrically conductive connection, only two of which are shown here for the sake of overview, and of course the network (see WO2005 / 053221, reference number 11 in this document ) may comprise more than two shunt elements T1, T2. The connection between the two shown branching elements T1, T2 is referred to below as line H, wherein the communication connections existing between other not shown branching elements are also based on this line section, so that line section H represents The route segments denoted H1, H2, H3, H4, H5 and other possible route segments in WO2005 / 053221.

[0024] For the shown shunt elements T1 , T2 only details of interest to the invention are shown. Other details are not shown for the sake of overview, wherein these elements are not shown in this fi...

Abstract

A branch element is specified for use in a communication network, whereby in the interplay of two branch elements designed according to the invention, a cleared fault in a communication medium stretching between the two branch elements, in particular a line, with a power supply cable and a current return cable, can be recognized with the help of a test current, which can be supplied by supplying test equipment-preferably provided in each branch element-and which can be detected using terminating test equipment-likewise preferably provided in each branch element-and whereby each terminating test equipment is designed and / or provided to deactivate a bus termination assigned to the respective branch element when the test current is detected.

Description

technical field [0001] The present invention relates to a branching element operating in a communication network, in particular as disclosed by WO2005 / 053221 of the applicant of the present invention, the entire disclosure content of which is hereby incorporated into this application. Furthermore, the invention relates to a network having at least two branching elements and a method for operating such a branching element. Background technique [0002] In a redundant communication network according to WO2005 / 053221, faults on main line sections are isolated by means of branching elements arranged in the communication network. A switch in the main line separates the faulty wire. Through the redundant switchover provided by the redundancy manager, the branch element spatially closest to the fault location is supplied with operating voltage from the side facing away from the fault. By means of this branching element, the faulty main line section is checked from both sides by f...
