Abstract
For interconnecting data networks which use cabling, which is actually provided for other purposes, as transmission medium for data packets, a private branch exchange is provided for connecting subscriber terminals via subscriber lines. The private branch exchange has an integrated interconnecting device via which data packets which are transmitted via the subscriber lines and which are coded into signals outside a frequency range used for communication with the subscriber terminals are extracted from a first subscriber line and extracted data packets are injected into a second subscriber line.
