A communications protocol interface is arranged at a central station of a telecommunications network and is responsive to a control message received from a network controller in accordance with a first message protocol to transmit the control message in accordance with a second message protocol to subscriber stations and is responsive to a control message received in accordance with the second message protocol to transmit the control message to the network controller in accordance with the first message protocol. The first message protocol is a balanced protocol with the communications protocol converter or the network controller able to initiate an exchange of information. The second message protocol is a master-slave protocol with the communications protocol interface acting as master. The second control message protocol operates over central station bus for communicating with at least one network element in the central station.
