ABSTRACT:
A switching network is disclosed which employs a simplified distributing frame to interconnect line selection units and group selection units. An intergroup trunking formula using multibit designations for each terminal is employed as a guide in forming the distributing frame. The system permits intermediate access to the network at the link-terminals by way of loop circuits coupled to the distributing frame. The use of distributing frame according to the invention enables the use of plug-in modular wiring.
