Description 1
<Definition> Indicates the amount of remaining time in minutes that the current message shall be active. The time shall be accurate to the nearest second and rounded up to the next full minute. For example, a value of 2 shall indicate that the time remaining is between 1 minute and 0.1 seconds and 2 minutes. Page 172 NTCIP 1203 v02.35 When a new message is activated with a minute-based duration, or this object is directly SET, the minute-based duration value shall be multiplied by 60 to determine the number of seconds that the message shall be active. Thus, if a message activation is for 2 minutes, the DMS will be assured to display the message for 120 seconds. The value 65535 indicates an infinite duration. A value of zero (0) shall indicate that the current message display duration has expired. A SET operation on this object shall allow a Central Computer to extend or shorten the duration of the message. Setting this object to zero (0) shall result in the immediate display of the dmsEndDurationMessage. <Unit>minute <Object Identifier> 1.3.6.1.4.1.1206.4.2.3.6.4
