Description: The value of tmnxMcPathMdaOperChlTimeRemain indicates the time remaining before the bandwidth update timer for the channel on the MDA expires. The bandwidth update timer determines how often multicast bandwidth is updated for a channel. When the value of this field becomes zero indicating that the bandwidth timer has expired, the bandwidth of the channel represented by the field tmnxMcPathOperChlIngLastHighest is updated to the value of the field tmnxMcPathOperChlIngSecHighest. If the timer is restarted, it indicates that the current bandwidth of the channel has either stayed the same or increased since the last poll.
