A telecommunication system is configurable so that there can be flexible control of a switching command issued by an application to a platform where the switching command is executable in (a) a first execution mode in which the switching command is executed simultaneous with switching and verified or (b) a second execution mode in which the switching command is executed immediately and without verification. The application can be run to cause the switching command to be sent to the platform and the platform can execute the switching command received from the application. At least one of testing on a case-by-case basis and deciding which execution mode should be utilized for execution of the switching command can also occur before the sending of the switching command and/or before the executing of the switching command.
