Abstract: A communications terminal (10) is to be configured for operation of a new service or application by connection to a service provision platform (12) over a connection (11). In order to do this, an installation server (15) generates instructions to a user terminal (13) over a separate link (14). These instructions are used to configure the communications terminal (10) to operate the service required. The terminal (13), separate link (14) and installation server (15) are then used to monitor, over a connection (19) independent of the newly-installed connection (11), the response of the service provision platform (12) to the test transmissions sent to it from the terminal (10) over the new connection (11), and to initiate test messages from the service provision platform (12) to the communications terminal.

Abstract: Data signals (e.g DTMF tones) transmitted on a telephone call between a customer terminal (1) and a call center platform (4) are diverted at the call center platform 4 to a secure payment system (3) such that the call center operative cannot intercept them. In order to verify that this has been done, the security system provides access to the user over a connection (23,230) independant of the connection (34,41) to the call center that allows the user to independently verify that the secure connection 34 has been made. This may take the form of returning the user's calling line identity (CLI) for the connection (34) over the independant connection (23/230) or, where CLI is not available, transmitting a one-time code over one of the links for the user to return over the other. The customer can continue to talk to the call center operative as only DTMF tones are diverted.
