Circuit arrangement for a telephone system, particularly a telephone branch exchange, with speech and signal path through- connection via serially connected matrices for circuits of different types

摘要

The terminal stations can be connected to columns or rows of matrices (K1, K7) with switching points which can be actuated independently of one another and to the rows or columns of these matrices (K1, K7), junction lines can be connected which connect matrices (K1, K7) of different terminal station groups and establish connections to different matrices (KA12, QS12) connecting through junction lines, in which arrangement different connecting matrices (KP1, KK, KC11, KS) can be successively interposed in these junction lines for circuits of different types. <IMAGE>
