This read-write, persistent value defines the time window, in minutes, used together with cmmModemResetLimit to judge whether a modem is repeatedly resetting badly enough to be declared faulty. Admins tune this window to match how quickly a genuinely faulty modem tends to cycle versus how far apart occasional benign resets normally occur. For example, pairing cmmModemResetTime of 10 minutes with a reset limit of 3 means three or more resets within any 10-minute span would trigger a fault declaration.
