Abstract

PURPOSE:To obtain excellent constitution in spacewise and economy, by constituting the complete group of one one-stage link every a given subscriber group and providing a plurality of this complete group. CONSTITUTION:The number of lines n per one complete group is corresponded to one switch group HG of the local exchanger to constitute the part in HG as one stage complete link. This is provided for a plurality corresponding to HG. With this provision, the number of switches required taking the number of subscribers as m, the number of switches as l, and m=nl, is 1 and it means 1/l in comparison with conventional systems and the space is also reduced to 1/l. Accordingly, the cost required for installation is reduced to about 1/l. Further, with this constitution, the number of switches required accompanied with the increase in the subscribers K is DELTAl, if m+k=n(l+DELTAl) is established, and it can be the switch increase by one for the increase within the range of k<n.
