A telecommunications system incorporates a switch based private network having a transparent network signalling system and having a plurality of nodes interfacing each via a switch with an intelligent public network. The public network incorporates a service control point having associated therewith a database containing destination addresses corresponding to call numbers received from the private network. The database provides routing data for call independent signalling information in response to requests from a node on behalf of a private service provided to a user of that node and from a public network switch on behalf of a private service provided to a directly connected user of that switch.
