Abstract
A private branch exchange for use in telephone systems comprises at least one basic module connected to the branch lines, first equipment connected line by line and second inter connection equipment. The base module includes interior line equipment(I1-Ii) and exterior line equipment (E1-Ei) with interconnection circuits (C1-CK) and a microprocessor (MP1). The base module is connected to a certain number of subscribers via interior lines (LI1-LI1) and to the central public system by exterior lines (LE1-LEi). Switching may be via a pulse code modulation system. The microprocessor controls interconnection and emission of calling tones etc.
