Abstract The ATM based B‐ISDN offering a multiplicity of services in an integrated way represents the future communication network. One of the major points relates the signalling system to be adopted in order to fulfil the high flexibility the B‐ISDN requires. The first part of this document deals with the general requirements of the B‐ISDN signalling system, analyzing the new call and connection control concepts and giving some guide‐lines for a modelling activity. Considerations for a long‐term signalling system, which will have to handle a multiplicity of services, are also presented: multimedia services, complex call configurations, transitions among them during the lifetime of a call, and re‐configurations of attributes values for a connection are described. The second part proposes some basic issues for a preliminary example of signalling system which handles ATM point‐to‐point connections between two users or between a user and a specialized node, supporting services which require centralized resources within the network, such as connectionless or multimedia services.
