Re-arrangeable analog electrical cross connect

摘要

A solid-state electronic switching system is disclosed. The switching system may be used to provide re-arrangeable analog electrical cross connections between telephone lines from a telephone company's central office and telephone lines that lead to subscribers' homes. The central office may reallocate services, without dispatching a technician, by issuing re-arrangement commands that reconfigure the analog electrical cross connections in the switching system. The switching system has been designed so that it may be used to interconnect telephone lines on which analog telephone services are provided.
