ABSTRACT:
A system and methods are disclosed in which two telephone calls are terminated simultaneously provided that one call is a local call and the second call is a trunk call and further provided that the local call and trunk call originate in separate line units. This is made possible by dividing a central office telephone switching system into two halves wherein each half includes both number translator circuits and code translator circuits and wherein each half includes both local register groups and trunk register groups. An allotter alternates between the register groups in each half of the circuit while indexing the register groups in order to match a local call placed in one-half of the circuit with a trunk call placed in the other half of the circuit for simultaneous termination.
