摘要：
A slave switch having a number of connections for traffic with switch-external users, and a number of extensions intended for connection with switch-internal users, is disclosed. The slave switch is characterized in that it is constructed to initiate originating calls only, and in that the switch includes by-pass signalling means. A method of communication between the slave switch and a master switch is also disclosed.
