Abstract
An interface circuit is described for interconnecting a packet switched system to a circuit switched system which enables a uniform dialing plan to be utilized to establish intra-system or inter-system connections. This is accomplished by assigning each terminal of the packet switched system a unique terminal address similar to the extension number used for terminals of the circuit switched system. The interface also distinguishes data call set-up requests from other control commands received from the packet switched system.
