Branch element for operating in a communication network, network and method for operating a branch element

摘要

The shunt unit (T1) has a line (H) with two ends such as current supply lead (SZ) and current rear guiding lead, which are connected to a redundancy manager. The manager is designed to interconnect the two ends with one another in an event of an error. Each of a set of supply testing devices is provided for supplying testing current to the line. Each of a set of terminal testing devices is provided for detecting the testing current on the line. Each terminal testing device is configured for deactivating a bus termination assigned to the shunt unit, during detection of the testing current. An independent claim is also included for a method for operating a shunt unit.
