# Session Time-Out

Certain protocols and types of sessions require timely responses from the Destination, or else the session is taken down. If the protocol does not specify a time-out, this parameter will. This parameter is only relevant for OTP (Over the Phone programming) and FP (Front Panel programming) sessions. The purpose is to assure that the RTU will not be inadvertently be left in programming mode, since calls to destinations will not occur while the RTU is in this mode.
