Abstract:
In a switching system for establishing connections related to two types of functions, a method of establishing a call received as an incoming call for a first type of function and transmitted as an outgoing call for a second kind of function, comprising the steps of:receiving said call in said switch; seizing a real first time-slot associated with a connection for a first type of function; establishing a virtual connection between said first time-slot and a virtual time-slot for said first function; seizing a real second time-slot for said call associated with a connection for a second type of function; establishing a virtual connection between said second time-slot and a virtual time-slot for said second type of function; and connecting said real first and said real second time-slot for completing said call; whereby no physical loop-around trunk is required for said connection, even though said connection apparently comprises two separate connections, one for each function and uses software as if two connections were being established.
