Abstract
Low space requirements, ease of installation, highswitching speed, nominal maintenance requirements, and highly automated production are demands imposed on modem exchanges. The crosspoint system developed by Siemens AG has been specially designed to meet these requirements. Since most teleprinter exchanges are rated for a capacity of less than 100 subscribers, the first embodiment of the system principle is a subdistrict exchange catering to 50 subscribers and permitting expansion for a total of 400 subscribers. One version of district exchange intended for major switching applications is engineered as a transit exchange with trunk lines only.
