Mechanisms of connection establishment
The request for establishment of a TeleService connection is triggered by the engineering
station. This request is sent via the intranet or Internet to the TeleService server (telecontrol
server or TeleService gateway).
The TeleService server forwards to request to the CP in the S7 station. The TeleService
server sends the request by e-mail to the SMS gateway which converts the e-mail and
forwards it as an SMS to the CP in the S7 station via the mobile wireless network.
The TeleService connection is finally actively established by the CP.
