TRANSFER CIRCUIT

A transfer system for providing transfer services to trunk circuits involved in connections between inside and outside parties. In response to a signal from the inside party, a trunk circuit is connected to any one of a plurality of transfer circuits through a switching network. The transfer circuit seizes the common control through a line circuit and transmits dial pulses received from the trunk circuit to complete a transfer connection to a transfer party. If the transfer party is an inside party, the transfer circuit, in response to a subsequent signal from the initial inside party, sets up a conference connection. When the initial inside party hangs up, the transfer circuit enables a transfer common control circuit to seize the common control and to set up a second connection between the transfer party and the trunk and thereafter releases the transfer connection through the transfer circuit. Safeguards are provided to assure that the second connection is properly established prior to the disconnection of the transfer connection.
