Modem DTE Inactivity Timeout
1.3.6.1.2.1.38.1.6.1.5
The amount of idle time in minutes that the modem will wait before disconnecting a connection. When a call is connected and no data is transferred (continuous marking condition) on both circuits 103 and 104 for the specified time, the DCE disconnects the call. If the value is 0, no idle disconnect will occur. This function applies to asynchronous dial operations only and is intended for administrative control over idle connections.
