Abstract: Telephone network service logic relating to calls over the telephone network to a customer terminal, uses both terminal functions and network functions. The terminal has a service logic script for execution at the terminal to control the terminal functions. To control the execution of this script remotely from the network, a script-control message is determined and sent over the telephone network to the terminal. This may use the GR30 message format, with an additional call qualifier specific to the terminal service logic script, and the type of control being requested, e.g., start execution or terminate the script. This enables the reliability of the interaction between the service logic at the network side, and the service logic script at the terminal to be improved. This enables announcement type services to be provided in which a loudspeaker on the terminal can be remotely controlled to make verbal announcements without requiring customer action to lift a receiver.

Abstract: In methods and apparatus for providing suppressed ringing access to a subscriber line, a connection request is sent from a server to a telecommunications switch and the switch performs a connection routine in response to the connection request to connect the server to the subscriber line. The connection routine is adapted to avoid audible ringing of a telephone set connected to the subscriber line. The connection request comprises a signal indicating a subscriber line to which the server is to be connected and a signal indicating that suppressed ringing access to that subscriber line is desired. The methods and apparatus avoid the need for especially provisioned trunks between the server and the terminating switches by including in the connection request a signal indicating that suppressed ringing is desired and by making the telecommunications switch responsive to that signal.
