First Claim
Patent Images
1. A communication system comprising:
- at least first and second communication subscribers, each communication subscriber respectively including means for generating signals to be transmitted and means for interpreting signals received; and
at least one network cable electrically connected between the first and second communication subscribers via which an at least two-channel bidirectional transmission of the data in the form of electrical signals simultaneously occurs between the first and second communication subscribers, the at least one network cable further connected to a network termination via which the first and second communication subscribers can be supplied with energy;
wherein the network cable is an at least three-lead, shielded network cable including a conductor, a zero conductor and a protective conductor, the conductor and the zero conductor forming a first transmission channel, and the protective conductor forming a second transmission channel; and
the network termination is a single-phase network termination.

Abstract
A communication system having at least two communication subscribers unidirectionally or bidirectionally exchanging data that are electrically connected to one another via at least one network cable which is in turn, connectible to a network termination via which energy can be supplied to the communication subscribers and via which an at least two-channel transmission of data in the form of electrical signals can occur at the same time from a first to a second communication subscriber.
