Circuit arrangement for telecommunication switching systems in, particular telephone switching systems, having selectable connection-specific switching devices

摘要

Announcement trunk repeaters (B1-Bx) for various announcements are combined to form a common trunk group. One recorded-announcement device (N1-N99) for a specific announcement is reached in each case from an announcement trunk repeater via selectors (L1-Lx). Combining the announcement trunk repeaters (B1-Bx) to form a common trunk group enables their loading to be balanced. Particularly important for public recorded announcement services in cases of disaster. <IMAGE>
